1 Appendix B Citrix CCA Exam Self Test Appendix 1

2 2 Appendix B Self Test Appendix Chapter 1: Installing and Managing Citrix XenApp 5.0 Server 1. Within the farm model are two technologies that make the XenApp on-demand enterprise function. What are they? (Choose two correct answers.) A. Remote Desktop Protocol (RDP) B. Independent Management Architecture (IMA) C. Independent Computing Architecture (ICA) D. Common Gateway Protocol (CGP) Correct answers and explanations: B and C. The two technologies that make the XenApp on-demand enterprise function are Independent Management Architecture (IMA) and Independent Computing Architecture (ICA). Incorrect answers and explanations: A and D. The Remote Desktop Protocol (TCP Port 3389) is utilized by Windows Terminal Services and is not used by XenApp. The Common Gateway Protocol (also known as session reliability, TCP Port 2598) is a feature of the XenApp environment but is not necessary to make the on-demand enterprise function. Since IMA and ICA are requirements for the functionality of a XenApp on-demand enterprise, only B and C are correct. 2. What is the key to a successful XenApp implementation? A. An adequate number of servers B. A well thought out design C. Proper memory and storage D. Trained systems engineers Correct answer and explanation: B. A well thought out design will encompass the proper number of servers, the required hardware for memory and storage, and the proper personnel to perform the implementation. Incorrect answers and explanations: A, C, and D. An adequate number of servers, proper memory and storage, and trained systems engineers are all correct answers, but any one alone will not necessarily ensure a successful XenApp implementation. Therefore B is the best answer. 3. Your XenApp farm is utilizing an MS Access database as the farm datastore, and the XenApp Server on which the datastore resides has crashed.

3 Self Test Appendix Appendix B 3 When attempting to recover from your last backup, the backup image is corrupted and will not restore properly. You know that you have another backup that is off-site, but it will take one day to have the media delivered. How long does your farm have before additional problems start occurring? A. 24 hours B. 48 hours C. 96 hours D. 0 hours Correct answer and explanation: D. With Presentation Server 3.0 the datastore grace period was removed. Prior to that, if the data store was offline for over 96 hours, users could no longer connect to the farm. With Presentation Server 3.0 and later, if the datastore is offline, users can still connect to the farm. It should be noted that administrators will be unable to make any modifications to the farm until datastore connectivity is restored. Therefore D is the only correct answer. Incorrect answers and explanations: A, B, and C. Older versions of Presentation Server had a datastore grace period of 96 hours before connections were denied to the farm, but that configuration was removed in Presentation Server You are the XenApp administrator of a large XenApp farm, and you have five administrators working for you that can make configuration changes to the XenApp environment. You know that you can track configuration changes to XenApp via Configuration Logging. What are the steps required to enable Configuration Logging? A. Define the Configuration Logging database access permissions, Set up the Configuration Logging database, Configure the Configuration Logging database connection, Test the connection to the Configuration Logging database, Set the Configuration Logging properties, Delegate administrative permissions, if needed. B. Define the Configuration Logging database access permissions, Set up the Configuration Logging database, Configure the Configuration Logging database connection, Test the connection to the Configuration Logging database, Delegate administrative permissions, if needed, Set the Configuration Logging properties.

4 4 Appendix B Self Test Appendix C. Set up the Configuration Logging database, Define the Configuration Logging database access permissions, Configure the Configuration Logging database connection, Test the connection to the Configuration Logging database, Set the Configuration Logging properties, Delegate administrative permissions, if needed. D. Set up the Datastore database, Define the Datastore database access permissions, Configure the Datastore Logging database connection, Test the connection to the Datastore database, Set the Configuration Logging properties, Delegate administrative permissions, if needed. Correct answer and explanation: C. The correct order of steps to enable configuration logging is: Set up the Configuration Logging database, Define the Configuration Logging database access permissions, Configure the Configuration Logging database connection, Test the connection to the Configuration Logging database, Set the Configuration Logging properties, Delegate administrative permissions, if needed. Incorrect answers and explanations: A, B, and D. You cannot define configuration logging database access permissions prior to configuring the database itself, so A and B are incorrect. Since the Configuration Logging database is separate from the Datastore database, D is incorrect. 5. You have upgraded your Citrix environment of 15 Presentation Server 4.0 Servers to XenApp 5.0. At installation time, you did not select to enable IMA Encryption, which utilizes the AES encryption algorithm to protect sensitive data in the IMA datastore. Now, you would like to enable IMA encryption on just two servers that handle sensitive data. What are the steps necessary to enable IMA encryption on these two servers? A. Generate a key file, make the key file available to all servers in the farm, load the key on every server in the farm, enable IMA encryption B. IMA Encryption cannot be enabled in this fashion. IMA Encryption is a farm-wide setting C. Generate a key file, make the key file available to all servers in the farm, load the key on only the two sensitive servers, enable IMA encryption D. Generate a key file, make the key file available to the two sensitive servers, load the key on the two sensitive servers, enable IMA encryption on the two sensitive servers

5 Self Test Appendix Appendix B 5 Correct answer and explanation: B. IMA Encryption is a farm-wide setting and is an all or none setting; therefore B is the correct choice Incorrect answers and explanations: A, C, and D. Answer A provides the correct way to enable IMA encryption for the entire farm. Answers C and D are incorrect because IMA Encryption cannot be applied to individual servers and not others within the same farm. 6. You are the administrator of XenApp farm consisting of 45 XenApp 5.0 Servers. Your executive management has informed you that the company will be acquiring the assets of another company, which will double your user load and XenApp assets. Currently, you are utilizing MS Access as your datastore. Based on this new information, you have decided to migrate your datastore to a SQL Server 2005 cluster running on Windows Server What are the steps required to successfully migrate ALL servers in your farm to the new datastore? A. Run DSMAINT with the migrate option on the SQL 2005 Server, run DSMAINT with the config option on each XenApp server in the farm B. Run DSMAINT with the migrate option on the XenApp Server holding the datastore, run DSMAINT with the config option on each XenApp Server in the farm C. Run DSMAINT with the config option on the XenApp Server holding the datastore, run DSMAINT with the migrate option on each XenApp server in the farm D. Run DSMAINT with the upgrade option on the XenApp Server holding the datastore, run DSMAINT with the config option on each XenApp Server in the farm Correct answer and explanation: B. You must run DSMAINT with the migrate option on the XenApp Server where the datastore resides first, then you must run DSMAINT with the config option on all remaining XenApp servers in the farm. In addition, you must stop and restart the IMA service on all servers in the farm. Incorrect answers and explanations: A, C, and D. Answer A is incorrect because the DSMAINT command will not be available on the SQL 2005 server. Answer C is incorrect because you must migrate to the new datastore first using the DSMAINT with the migrate option. Answer D is incorrect because there is no upgrade parameter for the DSMAINT command.

6 6 Appendix B Self Test Appendix 7. You are one of a group of XenApp administrators working for an automotive parts supply company that has recently decided to utilize XenApp 5.0 for delivering applications to its employees. The company has 17 locations worldwide with a total of 3000 employees and wants to publish about 75 applications. The company already utilizes Oracle as its preferred database for other applications and has Oracle DBAs employed. Two of the XenApp administrators have said that XenApp must run on SQL Server You are the most senior of the administrators, and your management has asked you what the best solution would be. A. Recommend utilizing MS Access as the datastore because no additional cost is involved. B. Agree with the other administrators that XenApp should be installed on SQL Server C. Recommend utilizing MS SQL Express because it is free and more robust than the default MS Access datastore. D. Explain that XenApp can utilize several different databases and that, since the company already has an Oracle infrastructure in place with the DBA experience AND that the sizing requirements of the new farm dictate using a robust database, you recommend using Oracle as the datastore. Correct answer and explanation: D. The sizing requirements dictate the need for a database that only SQL Server 2005, IBM DB2, or Oracle best provides. In this case, the organization already has Oracle expertise and Oracle meets the sizing requirements, so D is the best choice. Incorrect answers and explanations: A, B, and C. Answers A and C are incorrect because of the sizing requirements. Even though the farm could be configured using MS Access or SQL Express as the datastore, as more load is placed on the farm, problems will occur. Answer B is incorrect because XenApp can utilize MS Access, MS SQL Express, MS SQL Server 2005, IBM DB2, and Oracle. MS SQL Server 2005 could be utilized but is not the best choice in this scenario. 8. You are getting ready to deploy XenApp 5.0 on five servers, with new installations of Windows Server 2008 already installed. What is the best way to quickly install XenApp to the new servers? A. Create an unattended answer text file and use that with the UNATTENDEDINSTALL.EXE.

7 Self Test Appendix Appendix B 7 B. Install XenApp on one server and configure it; then, using a product such as Symantec Ghost, clone the server image to the remaining servers. C. Create server provisioning software and hardware to install XenApp. D. Manually install XenApp on each of the five servers. Correct answer and explanation: A. Of all the options, answer A is the best. This scenario will require that two scripts be created one for creating a new farm and one for servers joining the farm. Unattended installs can also be initiated via the MSIEXEC command line as well. Incorrect answers and explanations: B, C, and D. Answer B is not the best choice, even though you could install XenApp on a single server and then clone it to the others, but the problem here is that since there are only five servers, the installation is probably utilizing MS Access as the datastore, and you cannot clone the datastore XenApp Server. Answer C is not the best choice because in order to leverage the savings provided by server provisioning, you should have a greater number of servers. Answer D will take more time than an unattended script simply from the manual interaction required. 9. You are researching various hardware and storage options that provide redundancy in case of hardware failure for the new XenApp 5.0 farm you have been tasked to build. What is the optimal configuration on which to install XenApp 5.0 considering costs and performance as factors? A. RAID level 0 B. RAID level 1 C. RAID level 5 D. RAID level 10 Correct answers and explanations: B. RAID 1 will provide mirror disk sets at a lower cost to implement than other options; therefore, Answer B is correct. Incorrect answers and explanations: A, C, and D. RAID 0 has no redundancy, so Answer A is incorrect. Since most XenApp servers are typically smaller 1 or 2U servers, the additional size and costs associated with RAID 5 typically fail to provide the return on the investment, so Answer C is incorrect. RAID 10 combines RAID 1 and RAID 0 and provides the best performance but is the most costly; thus Answer D is incorrect.

8 8 Appendix B Self Test Appendix 10. What are the minimum prerequisites for installing XenApp 5.0 on Windows Server 2003? A. Microsoft.NET Framework Version 2.0, Java Runtime Environment ( JRE) 1.5.0_09, Visual J#.NET Version 2.0 B. Microsoft.NET Framework Version 3.0, Visual C (Version 8.0, Service Pack 1), Visual J#.NET Version 2.0, Java Runtime Environment ( JRE) 1.5.0_11 C. Microsoft.NET Framework Version 2.0, Visual C (Version 8.0, Service Pack 1), Visual J#.NET Version 2.0, Java Runtime Environment ( JRE) 1.5.0_11 D. Microsoft.NET Framework Version 3.5, Visual J#.NET Version 2.0, Java Runtime Environment ( JRE) 1.5.0_09 Correct answer and explanation: A. Answer A is correct based on the prerequisites checklist for XenApp 5.0 on Windows Incorrect answers and explanations: B, C, and D. Answer B is the minimum prerequisite needed for XenApp 5.0 on Windows 2008 and is thus incorrect. Answer C has Visual C++ listed, which is not a requirement for XenApp on Windows 2003 and is therefore incorrect. Answer D has NET Framework Version 3.5 listed, which is not a requirement for XenApp on Windows 2003 and is thus incorrect. 11. You are the administrator of a Citrix Presentation Server 4.0 farm of 10 servers all running on Windows What are the steps necessary to upgrade and migrate your farm to XenApp 5.0 on Windows Server 2008? A. Upgrade all servers to Windows Server 2008; then upgrade XenApp to 5.0. B. Upgrade to XenApp 5.0 (Presentation Server 4.5 FR1) and then upgrade the OS to Windows Server C. Install XenApp 5.0 on a new Windows 2008 server, add it to your current farm, then migrate the datastore. D. This option is not available. Citrix does not support upgrading the operating system. You must create a new XenApp 5.0 farm running on Windows Server 2008 and migrate your settings to the new farm. Correct answer and explanation: D. The only correct answer is D because Citrix does not support upgrading the operating system.

9 Self Test Appendix Appendix B 9 Incorrect answers and explanations: A, B, and C. You must create a new XenApp 5.0 farm running on Windows Server 2008 and migrate your settings to the new farm. Answers A, B, and C are not possible as stated in Citrix documentation. 12. You are performing the initial installation of Citrix License Server. What are your options as to the kind of web server you can install Citrix License Management Console on? (Choose two correct answers.) A. Microsoft IIS B. Apache C. IBM WebSphere D. BEA WebLogic Correct answers and explanations: A and B. The Citrix License Server Management Console runs as a web service and requires that either Microsoft IIS or Apache web server be installed prior to installation. Incorrect answers and explanations: C and D. Answers C and D are incorrect because Citrix only supports IIS and Apache for the License Server Management Console. 13. You currently have a Presentation Server 4.0 farm with the License Server that came with that version, and you also have Subscription Advantage. What steps must you complete to upgrade your licensing to XenApp 5.0? A. Upgrade your Presentation Server 4.0 licenses to XenApp 5.0 on the MyCitrix web site and copy to your existing License Server. B. Install a new License Server with the same name as the old License Server and copy the old license files to the new server. C. Upgrade the License Server to the latest License Server, which is included with XenApp 5.0, fulfill your 4.0 licenses to XenApp 5.0 on the MyCitrix web site, and create a new license file to copy to your upgraded server. D. With Subscription Advantage, nothing further needs to be done to the existing licenses, and License Server is compatible with XenApp 5.0. Correct answer and explanation: C. Answer C provides the correct steps for license migration and License Server upgrade as stated by the Citrix Licensing: Migrating, Upgrading, and Renaming document.

10 10 Appendix B Self Test Appendix Incorrect answers and explanations: A, B, and D. Answer A is incorrect because even though you must upgrade or fulfill your existing licenses on the MyCitrix web site, the licensing server provided with 4.0 is not compatible with XenApp 5.0. Answer B is incorrect because even though you have the correct licensing version, you must still upgrade your licenses on the MyCitrix web site. Answer D is incorrect because you must manually fulfill or upgrade your licenses on the MyCitrix web site AND you must still upgrade your License Server to the latest version that is compatible with XenApp What are the steps required to publish an application (such as Notepad) in the Access Management Console? (Choose all that are correct.) A. From the Access Management Console, expand the Farm node, right-click Application s, select New Publish Application, follow the steps in the Publish Application Wizard. B.

From the Access Management Console, expand the Farm node, right-click Applications, select Publish Application, follow the steps in the Publish Application Wizard. Correct answers and explanations: A and B. Both A and B are correct. You may select to publish a new application using either method to invoke the Publish Application Wizard. Incorrect answers and explanations: C and D. Answer C is incorrect because you must select Publish Application after you select New. Answer D is incorrect because you must select New and then select Publish Application. 15. What are all of the snap-ins that can be installed in the Access Management Console? A. Report Center, Licensing, Applications, Presentation Server, Dashboard, My Knowledge, Web Interface, Hotfix Management B. Report Center, Licensing, Diagnostic Facility, Presentation Server, Dashboard, My Knowledge, Web Interface, Hotfix Management, Documentation

11 Self Test Appendix Appendix B 11 C. Report Center, Licensing, Diagnostic Facility, Presentation Server, Dashboard, My Knowledge, Web Interface, Hotfix Management D. Licensing, Diagnostic Facility, Presentation Server, Dashboard, My Knowledge, Web Interface, Hotfix Management Correct answer and explanation: C. Answer C is correct because it lists all available snap-ins that can be installed in the Access Management Console. Incorrect answers and explanations: A, B, and D. There is no Applications snap-in, so Answer A is incorrect. There is no Documentation snap-in, so Answer B is incorrect. Answer D does not list Report Center as a snap-in and is therefore incorrect. 16. The XenApp Advanced Configuration tool replaced what prior Citrix management tool? A. Access Management Console B. Presentation Server Console C. Citrix Management Console D. ICA Configuration Console Correct answer and explanation: B. XenApp Advanced Configuration replaced the Presentation Server Console component; thus B is correct. Incorrect answers and explanations: A, C, and D. The Advanced Configuration Tool did not replace the Access Management Console, so Answer A is incorrect. The Citrix Management Console is an older component of the Citrix MetaFrame products, so Answer B is incorrect; there is no such console as the ICA Configuration Console, so Answer D is incorrect. 17. What methods can be used to create a new policy in the Advanced Configuration Tool? (Select all that apply.) A. Expand the Farm node, right-click the Policies node, select Create Policy. B. Expand the Farm node, right-click the Policies node, select New Policy. C. Expand the Farm node, right-click the Policies node, double-click the policy to configure. D. Expand the Farm node, highlight the policies node, select Actions New Policy from the file menu.

12 12 Appendix B Self Test Appendix Correct answers and explanations: A and D. Answers A and D are correct and either way may be used to create a policy. It should be noted that this only creates the policy and that the policy must still be configured. Incorrect answers and explanations: B and C. There is no option called New Policy, so Answer B is incorrect. Answer C describes how to configure a policy and is thus incorrect. 18. While using the Access Management Console remotely, you receive an error message when attempting to discover a server in your farm. What is the most likely cause of this error? A. This occurs when you use an account that does not have Distributed Component Object Model (DCOM) Remote Launch permissions on the remote server. B. You are running the Access Management Console within an RDP session. C. This occurs because the NTFS permissions are set incorrectly on the Access Management Console. D. This occurs when the account you are using does not have the proper.net permissions on the remote server. Correct answers and explanations: A. Answer A is correct. You must grant DCOM Remote Launch permissions to any Citrix administrators whom you allow to access the farm. Incorrect answers and explanations: B, C, and D. It makes no difference whether or not you are running the Access Management Console via an RDP session; so Answer B is incorrect. If NTFS permissions were set incorrectly, the Access Management Console would completely fail to launch, so Answer C is incorrect. There are no.net permissions, so Answer D is incorrect. 19. What is the best starting point for troubleshooting problems with XenApp? A. MyCitrix web site B. The Citrix Technical Support: Brief Troubleshooting Guide C. Citrix Technical Support D. Citrix Support Forums

13 Self Test Appendix Appendix B 13 Correct answer and explanation: B. Answer B provides the most comprehensive method of troubleshooting problems with XenApp. Incorrect answers and explanations: A, C, and D. Answer A, The MyCitrix web site does provide documentation on XenApp but does not provide ready answers to troubleshooting problems and is incorrect. Even though you could have Citrix Technical Support troubleshoot and potentially solve your problem, Citrix Technical support is not free, and the support engineers will want you to go through steps already documented in the Troubleshooting guide. Thus Answer C is incorrect. The Citrix Support Forums are an excellent source of information and many problems can be solved there, but bad advice can also be received. In many cases, the people who will help you will direct you to conduct basic troubleshooting identified in the troubleshooting guide. Thus Answer D is incorrect. 20. What are two ways to help identify possible causes of problems in your XenApp environment? (Choose two correct answers.) A. Implement XenApp Configuration Logging. B. Utilize an efficient Service Desk. C. Use a Change Management Process. D. Monitor server event logs. Correct answers and explanations: A and C. By using XenApp Configuration Logging, you can generate reports that can assist you in determining what changes have been made to your environment, who made them, and when they were made, so Answer A is correct. A change management system allows administrators and engineers to log any and all changes to a specific environment, to include which server is affected, the time, date and implementer at a minimum, thus Answer C is correct. Incorrect answers and explanations: B and D. While a service desk can help identify that there is a problem with your XenApp environment, it does not necessarily offer possible reasons for the problem, so Answer B is not the best choice. In addition, if a server experiences an outage because of a problem, the event logs will be unavailable to assist you in determining the problem, so Answer D is not the best choice.

14 14 Appendix B Self Test Appendix Chapter 2: Configuring and Maintaining the Citrix XenApp 5.0 Farm 1. You are attempting to install SmartAuditor into your XenApp farm. You are deciding which server to use as your administration server. Your XenApp farm is a mix of various Windows server editions. Which of the following servers is not supported by SmartAuditor? A. Windows Server bit edition B. Windows Server bit edition C. Windows Server bit edition D. All of the above versions of Windows server are supported Correct Answer & Explanation: A. SmartAuditor is not supported by Windows Server 2008, 32-bit or 64-bit. Incorrect Answers & Explanations: B, C, and D. Answers B and C are incorrect because SmartAuditor runs in both 32-bit and 64-bit versions of Windows Server Answer D is incorrect because Windows Server 2008 is not supported. 2. You plan to use Installation Manager to pass not only applications to servers within your server farms but also tasks. You are not familiar with the process of writing XML code for the creation of tasks. What tool can you use to create tasks? A. Advanced Configuration Console B. PowerShell C. Task Scheduler D. Access Management Console Correct Answer & Explanation: C. Windows Task Scheduler can be used to create scheduled tasks, which can then be exported and delivered via Installation Manager. Incorrect Answers & Explanations: A, B, and D. Answer A is incorrect because the Advanced Configuration Console is used for specific, advanced features of XenApp. Answer B is incorrect because PowerShell is used for the creation of scripts. Answer D is incorrect because the Access Management Console is used for the day-to-day operations of XenApp servers and farm, not for scheduling tasks.

15 Self Test Appendix Appendix B Your manager wants to implement session shadowing in your environment for user support. However, she has some concerns about the security of this technology. You explain to her that there are various measures that can be put into place in order to protect confidentiality. Which of the following answers is/are configurable option(s)? A. Prohibit being shadowed without notification B. Require Smartcard authentication C. Prohibit remote input when being shadowed D. Prohibit shadowing by application E. A and C F. A and B Correct Answer & Explanation: E. Session shadowing can be configured to require user notification and also prohibit remote input. Incorrect Answers & Explanations: A, B, C, D, and F. Answers A and C are incorrect because they only partially answer the question. Answer B is incorrect because Smartcards cannot be integrated with XenApp. Answer D is incorrect because shadowing is not configured by application. Answer F is incorrect because it only offers half the correct answer. 4. You have brought a brand new server into your Citrix XenApp farm. When the next data collector election occurs, you want this new server to take priority during the election. Which of the following options is NOT a possible choice for a predetermined preference? A. Required B. Most Preferred C. Preferred D. Default Preference E. Not Preferred Correct Answer & Explanation: A. There is no setting Required for predetermining data collectors. Incorrect Answers & Explanations: B, C, D, and E. Answer B is incorrect because Most Preferred is the first choice for a data collector. Only one server in a zone should have this distinction. Answer C is incorrect because Preferred is the next choice after Most Preferred. Multiple preferred servers can exist.

16 16 Appendix B Self Test Appendix Answer D is incorrect because Default Preference is the setting of a server which is set by default when a new server is brought online. If neither a Most Preferred or Preferred server is available, elections will take place from this pool of servers. Finally, Answer E is incorrect because servers set to Not Preferred will only become data collectors if no other server is available. 5. You are setting up administrative accounts for various members of your IT team. Certain administrators need rights to manage server workloads within the Citrix farm. Which of the following rights can be assigned to a custom administrator account? A. Assign Load Evaluators B. Edit Load Evaluators C. View Load Evaluators D. Load Manager E. All of the above Correct Answer & Explanation: E. Assign Load Evaluators allows administrators to assign load evaluators to servers and published applications.

You believe the issue is isolated to a particular server. Which of the following can be monitored using performance indicators? A. Bandwidth and compression for ICA sessions B. Individual virtual sessions of a client session C. Bandwidth constraints of Citrix XenApp clients D. Latency counters for ICA sessions Correct Answers & Explanations: A, B, and D. The built-in performance counters installed as part of XenApp server can monitor bandwidth compression, virtual channels, and latency of ICA sessions. Incorrect Answer & Explanation: C. Answer C is incorrect as this is not something that can be measured from the XenApp server. 11. Your manager is looking for the most cost-effective and easiest means to deploy the SmartAuditor Player to authorized users. Which of the following solutions are possible? A. Install the player on a Windows 2003 host and publish the application. B. Use an application deployment product such as Microsoft System Center Configuration Manager 2007 to deploy the application.

19 Self Test Appendix Appendix B 19 C. Stream the application to the desktops using XenApp application publishing. D. All of the above. Correct Answers & Explanations: A and B. You can manually install the player on a user workstation, publish it on a Windows 2003 XenApp server, or deploy it using technologies such as System Center Configuration Manager (SCCM), Group Policy, or similar technology. Incorrect Answers & Explanations: C and D. Answer C is incorrect as Citrix neither recommends nor supports streaming the player. Answer D is incorrect since C is incorrect. 12. You want to manage remote servers from a single administrative location. You have administrative tools running on a local server but are still unable to manage the remote servers. What protocol must you enable in order for remote management to work? A. RDP B. COM C. ICA D. DCOM Correct Answer & Explanation: D. DCOM is a protocol used to initiate remote procedure calls (RPC) on a server. DCOM is not enabled by default. Incorrect Answers & Explanations: A, B, and C. Answer A is incorrect because Remote Desktop Protocol (RDP) is the default Terminal Services protocol. Answer B is incorrect as it is similar to DCOM but an older version of the technology. Answer C is incorrect because ICA is the default Citrix communication protocol. 13. Your manager has asked you to create various administrative groups to handle very specific tasks within your XenApp farm. Which of the following answers are tasks groups that can be assigned to custom authority administrators? A. Administrative Folder tasks B. Super User tasks C. View-only tasks D. Printer Management Folder tasks E. Server Folder tasks F. Help Desk tasks

20 20 Appendix B Self Test Appendix Correct Answers & Explanations: A, D, and E. There are seven task groups from which tasks can be assigned to custom authority administrators: Administrators, Applications, Farm, Load Evaluators, Policies, Printer Management, and Servers. Incorrect Answers & Explanations: B, C, and F. Answers B, C, and F are incorrect because no such groups exist. 14. You are running both Citrix XenApp and Microsoft System Center Operations Manager 2007 in your IT enterprise environment. Your administrative team has asked to monitor the Citrix XenApp farm using SCOM. Which of the following objects can be monitored and reported on in SCOM? A. Citrix Zone B. Citrix Unsupported Server C. Citrix Unlicensed Server D. Citrix License Server E. All of the above F. None of the above Correct Answer & Explanation: E. The management pack for Systems Center Operations Manager 2007 allows you to monitor and report on 10 different objects: Citrix Deployment, Citrix Farm, Citrix Zone, Citrix Zone Data Collector, Citrix Farm Metric Server, Citrix Managed Server, Citrix Unsupported Server, Citrix Unlicensed Server, Citrix License Server, and Citrix Server. Incorrect Answers & Explanations: A, B, C, D, and F. Answers A, B, C, and D are incorrect because they only partially answer the question. Answer F is incorrect since all of the above answers are correct. SCOM will probably not be on the test but I do think Resource Manager and EdgeSight should be explored. 15. You check the Citrix support site and notice that there are several new hotfixes available to you to install on your XenApp farm. You are about to bring two new XenApp servers online shortly as well. What method of installation might you use to install these hotfixes without manually launching each one individually? A. Package the hotfixes together and stream them using a published application.

21 Self Test Appendix Appendix B 21 B. Use Citrix Installation Manager to deploy the hotfixes to the unconfigured servers. C. Create a custom installation that includes the hotfixes. D. You must install all hotfixes manually for security purposes. Correct Answer & Explanation: C. Before installing Citrix XenApp onto the new servers, you can create a custom installation which will include all the hotfixes you have chosen to include. Incorrect Answers & Explanations: A, B, and D. Answer A is incorrect because a hotfix is not an application and cannot therefore be streamed. Answer B is incorrect since Installation Manager will only work on servers that already have XenApp installed. Answer D is incorrect since you can automate hotfix installation. 16. Steamed applications use a specific type of file to provide information about the application that is being delivered. What is the name of this file? A. MST file B. MSI file C. Application profile D. Streaming profile Correct Answer & Explanation: C. An application profile contains critical information about the application being delivered to the end-user.

You mention as one of the advantages the ability to stream applications. Which of the following is NOT an advantage of streaming an application? A. Increased application speed B. Reduced application conflicts C. Single point of management D. Reduction in cost based on desktop support maintenance

22 22 Appendix B Self Test Appendix Correct Answer & Explanation: A. Streaming an application does not necessarily guarantee that it will run faster than one published in the traditional Citrix fashion or installed directly on a workstation. Incorrect Answers & Explanations: B, C, and D. Answers B, C, and D are all incorrect since they are all advantages of streaming applications. 18. You have recently upgraded to XenApp from Citrix Presentation Server. New workstations that you are deploying to employees have the latest Citrix client. Employees with existing computers will have their clients updated over the next three to six months. Your manager wants you to deploy a new application to all clients and wants to take advantage of application streaming. What setting should you use when publishing the application? A. Server desktop B. Content C. Accessed from a server D. Streamed if possible, otherwise accessed from a server E. Streamed to client Correct Answer & Explanation: D. The requirement from management was that the application be made available to all clients. Since the legacy clients do not support streamed applications, you would stream if possible or otherwise access it from the server in the traditional manner. Incorrect Answers & Explanations: A, B, C, and E. Answer A is incorrect since this would present an entire desktop to the end user. Answer B is incorrect as this is used to present documents and web pages. Answer C is incorrect because it does not use streaming at all. Answer E is incorrect since the legacy clients cannot support streaming and would not be able to access the application. 19. You have recently implemented Citrix EdgeSight for the management of your Citrix farm. You are new to EdgeSight and would like to know more information about the individual features of the product as you work with the management console. Which of the following would provide this type of help? A. Help Link B. Getting Started C. Enabling pop-up help D. None of the above

You are attempting to get more detailed help on a particular feature of EdgeSight. However, when you attempt to launch the Help Link, it fails with a Page Not Found error. What is the cause of this? A. You have not properly licensed EdgeSight. B. You did not choose to install the help files while installing EdgeSight. Launch the installation process again. C. You do not have access to the Internet from this server. D. You should use Getting Started instead. Correct Answer & Explanation: C. Help Link launches an online version of the help files. The server that is running EdgeSight must have Internet access. Incorrect Answers & Explanations: A, B, and D. Answer A is incorrect since licensing would not affect your access to the help files. Answer B is incorrect as there is no installation option for the help files, they are online. Answer D is incorrect because Getting Started only provides a brief overview of the features. Chapter 3: Configuring ICA Sessions 1. Darien is a user in your environment who works at a remote office. The location connects through a Metro E connection to a centralized office where the XenApp server farm exists. Darien attempts to launch Microsoft Word from the farm and is successful. As he is working, his application suddenly stops responding and an hourglass appears. Within a minute, the pointer reappears and he is able to continue working. Place the following items in order to best describe what most likely occurred in this situation. You may not use all of the available options. 1. The Session Reliability timeout on the XenApp farm was exceeded, so the session status returned to active.

24 24 Appendix B Self Test Appendix 2. The network connection from Darien s workstation to the XenApp farm was broken. 3. The user continued to appear connected. 4. The network connection was restored, so the application became responsive again and the user could work. 5. Session Reliability settings on the XenApp farm allowed the session to remain open on the server farm. A. 3, 2, 1 B. 2, 5, 3, 4 C. 5, 2, 3, 1 D. 2, 1, 4 Correct Answer & Explanation: B. This is the correct sequence. When the network connection between the client and server is interrupted the session remains open on the server due to Session Reliability settings. The user continues to appear connected during the interruption, and once the network connection is restored the application becomes responsive again and the user can continue working. Incorrect Answers & Explanations: A, C, D. Answer A is incorrect, because this is not the correct order of steps. Answer C is incorrect, because this is not the correct order of steps. Answer D is incorrect, because this is not the correct order of steps. 2. A user named Carlos calls you saying that he has just rebooted his workstation and he cannot launch the application he was logged on to before the reboot. When you log on to the console you see that many users are connected into your XenApp farm and are working normally on applications. What could be a possible cause of this issue? A. Carlos does not have permissions to access the server farm. B. The server to which Carlos is configured to connect is off. C. The IMA services on the server Carlos is connecting to are not responsive. D. Carlos must be granted permissions to the application he is trying to access. Correct Answer & Explanation: C. The IMA service on XenApp servers is required for new connections. Existing connections are not affected by restarting this service.

25 Self Test Appendix Appendix B 25 Incorrect Answers & Explanations: A, B, D. Answer A is incorrect, because Carlos would not have been able to log on if he did not have permissions to access the server farm. Answer B is incorrect, because users are not configured to connect to certain application servers. Answer D is incorrect, because the user stated that he had been using the application before the reboot, which implies he has permissions to the application already. 3. Session Reliability changes the way a client interacts with the XenApp farm in which of the following ways? Select two. A. Users can disconnect and reconnect to the sessions faster. B. If a user loses network connectivity her session does not disconnect. C. Disconnections are not permitted in order to keep sessions reliable. D. The default ICA port changes from 1494 to Correct Answers & Explanations: B, D. Answer B is correct, because brief disconnections from the network, as in wireless situations or remote office situations, do not result in automatic disconnection of an ICA session. Answer D is correct, because ICA traffic without Session Reliability enabled runs on port By enabling Session Reliability, the primary port for communication between client and server changes to Incorrect Answers & Explanations: A, C. Answer A is incorrect, because once a session enters a disconnected state Session Reliability is no longer a factor. Answer C is incorrect, because it is an invalid statement. Whether disconnections are allowed is not a feature or setting of Session Reliability. 4. A user is in the middle of crafting a PowerPoint presentation. He receives a phone call which is requesting his presence in another building. He decides to disconnect his session to PowerPoint and resume when he arrives in his new location. Which of the following best describes what the user must do to reconnect to his session once he arrives in the other building? A. Log on to the XenApp Plugin and the disconnected sessions will resume automatically. B. Log on to the XenApp Plugin and launch PowerPoint. C. Log on to the XenApp Plugin, right-click the XenApp System Tray icon, and click Reconnect Sessions. D. Log on to the XenApp Plugin, right-click the XenApp System Tray icon, and click Resume Sessions.

26 26 Appendix B Self Test Appendix Correct Answer & Explanation: C. From the right-click menu in the System Tray icon, Reconnect Sessions will be an available option which will reconnect a user to any disconnected sessions he may have. Incorrect Answers & Explanations: A, B, D. Answer A is incorrect, because disconnected sessions will not resume automatically with a new login. Answer B is incorrect, because launching the application will start a new session. Answer D is incorrect, because there is no Resume Sessions option. 5. Sally has successfully logged on to her XenApp Plugin client, and is now trying to launch an application but is receiving an error on each attempt. She is working from a satellite office today and this is the first time she has been in this location. As she asks around the office, she realizes that no one else in this location uses the XenApp Plugin. What is the most likely cause for Sally s failure to log on? A. Sally does not have permissions to the application she is trying to launch. B. Port 1494 is not open on the firewall from the satellite office to the main office. C. Port 2598 is not open on the firewall from the satellite office to the main office. D. Sally has locked out her user account from too many invalid logon attempts, so she has been restricted in launching applications. Correct Answer & Explanation: C. Session Reliability is enabled by default in XenApp 5.0, and the standard port used by the XenApp plug-in to launch applications is Once logon is completed, this port must be open from the client to the XenApp server farm for applications to launch successfully. Because Sally is in a satellite office, the firewall between the office and the main location where the XenApp servers reside mostly likely does not allow traffic on port Incorrect Answers & Explanations: A, B, D. Answer A is incorrect, because if Sally did not have permissions to the application the icon would not be rendered. Answer B is incorrect, because with session reliability enabled in the XenApp farm port 1494 is not the default port in use when an application is launched. Answer D is incorrect, because authentication credentials are passed when the user logs on to the XenApp Plugin client, which was successful for Sally.

27 Self Test Appendix Appendix B You have decided to use an MSI file to install the XenApp Plugin on the workstations in your environment. You utilize Active Directory Group Policy to install the MSI file on the machines of a group of pilot users. The users inform you that they are being prompted with a XenApp installation screen. Which of the following commands will allow you to create an MSI file that will install silently? A. msiexec /I B. msiexec /A C. msiexec /U D. msiexec /P Correct Answer & Explanation: B. /A is the correct switch to use with msiexec to launch the Client Packager and create an unattended installer file. Incorrect Answers & Explanations: A, C, D. Answer A is incorrect, because the /I switch is utilized for unattended installations. Answer C is incorrect, because the /U switch does not exist. Answer D is incorrect, because the /P switch does not exist. 7. A user is logged on to the network through a VPN connection. She has successfully launched an internal expense report tool from her XenApp plug-in. Suddenly her home Internet connection fails and she is disconnected from the VPN. What is the current state of her session on the XenApp farm? A. Disconnected, and she may reconnect to her session and continue working B. Disconnected, and she has lost her work C. Terminated, and she may reconnect to her session and continue working D. Idle, and she may reconnect to her session and continue working Correct Answer & Explanation: A. When a user unexpectedly loses her connection to a XenApp session, her session will enter a disconnected state, and as long as she reconnects before the disconnect timeout expires, she will be able to continue working where she left off. Incorrect Answers & Explanations: B, C, D. Answer B is incorrect, because if the session is in a disconnected state, she can reconnect and resume the application where she left off. Answer C is incorrect, because terminated sessions cannot be reconnected to. If a session is terminated, any unsaved work is lost. Answer D is incorrect, because an idle connection occurs only when a user remains connected but not active in the session.
