1 Appendix The Real MCTS SQL Server 2008 Exam 432 Self Test Appendix 1

2 2 Appendix Self Test Appendix Chapter 1: New Features in SQL Server You are setting up security for your new SQL Server 2008 installation. Management is concerned about security. What approach should you take to ensure security settings are optimal? A. Use the Surface Area Configuration Tool to secure the installation B. Use the new Security Analysis tool to secure the installation C. Use SQL Server Configuration Manager to secure the installation D. Use Windows Service Manager to enable and disable the appropriate services The correct answer is C. On the Start menu, point to All Programs Microsoft SQL Server 2008 Configuration Tools SQL Server Configuration Manager. Answer A is incorrect because the Surface Area Configuration Tool is no longer used to secure SQL Server Answer B is incorrect because there is no Security Analysis tool in SQL Server While Answer D may work, it s not the best answer. Your answer should be the most correct using the new features, even though some of the other answers may technically work. 2. You have been tasked with setting up standards for your SQL Server 2008 installation. You need to enforce a table naming convention. What is the best way to accomplish this in your SQL Server 2008 environment? A. Use Windows Group Policy B. Create DDL Triggers C. Create DML Triggers D. Create a Declarative Management Framework policy The correct answer is D. This is the most efficient way to accomplish the task of enforcing a table naming convention. Answer A is incorrect Windows Group Policy does not provide a mechanism for enforcing table naming conventions. While Answer B could would, it s not the best solution. Answer C is incorrect as DML triggers provide no means to control DDL code.

3 Self Test Appendix Appendix 3 3. You have been asked to create a backup of your production database and restore it on a development server. Your production server is using the full recovery model. Full backups are taken Monday and Wednesday. Transaction log backups are taken every hour. Today is Friday. The backup needs to be created as quickly as possible. What s the fastest way to get the latest database copy while minimizing impact to production? A. Create a normal backup. Use that to restore to development. B. Create a Copy Only Backup. Use that to restore to development. C. Use the Wednesday backup. Restore the transaction log backups since Wednesday. D. Copy the.mdf and log files and use SP_attach. The ideal situation would be to use B, the Copy Only Backup. Copy Only doesn t affect the backup chain and will provide the quickest solution while minimizing interruptions. Answer A will affect the backup chain, so it s somewhat disruptive. Answer C is not the fastest method, and there would be quite a few transaction logs to restore. Answer D would require stopping the SQL service on the production server, rendering it unusable during the copy. 4. You have a SQL Server 7.0 database and would like to move it to a new SQL Server 2008 instance. The database is part of an FDA-validated system and cannot be changed at all? How can this be accomplished? A. Restore the 7.0 database on your new server and set the compatibility mode to 7. B. You must upgrade the database to SQL 2005 or greater. C. Restore the 7.0 database on your new server and set the compatibility mode to 6.5. D. Copy the.mdf and log files and use SP_attach. The correct answer is B. Answers A and C are incorrect as SQL Server 2008 does not support 7 or 6 compatibility. Answer D is incorrect as the database must be upgraded and cannot just be attached. 5. You have an application that is being upgraded from SQL Server 2005 to SQL Server You notice that some stored procedures are not working correctly. An excerpt is as follows:

4 4 Appendix Self Test Appendix SELECT * FROM Territories, Region WHERE territories.regionid *= region.regionid What should you do to resolve the issue? A. There is no issue. The problem lies elsewhere. B. The join syntax is incorrect. Replace with left join. C. The select is incorrect. You need to enumerate the fields. D. The where clause should be = not =. The answer is B. The join syntax is no longer supported. Answer A is incorrect, as the old join syntax ( = and = ) will no longer work. Answer C is not correct; although Select will work, it is not good practice. Answer D is incorrect as it will change the left join to an inner join, which would change the overall function of the select statement. 6. Your disk is almost full on the transaction log drive for a database server. How can you resolve this issue? A. Use BACKUP LOG WITH TRUNCATE_ONLY B. Change the mode to simple and shrink the log C. Reinstall SQL D. Drop the database and restore from the last backup The correct answer is B. Answer A would be the answer with SQL Server 2005; however, this command is no longer available. Answer C will not solve the problem, and Answer D would result in data loss and could take a while. 7. You want to enforce a standard naming convention for stored procedures. What s the best way to do this in SQL Server 2008? A. Create a DDL trigger B. Use the performance data warehouse C. Create DML triggers D. Use the SQL Server 2008 Declarative Management Framework The correct answer is D. The DMF will allow you to perform the task at hand. Answer B has nothing to do with enforcing naming conventions. While Answer A could work, it s not the best approach. Answer D will not allow you to perform the task of enforcing naming conventions.

5 Self Test Appendix Appendix 5 8. You want to enforce a standard naming convention for tables and stored procedures. Your company has two SQL Server 2008 servers and 60 SQL Server 2005 servers. You need to use the same solution on all servers. What s the best way to do this in SQL Server 2005 and SQL Server 2008? A. Create a DDL trigger for all servers B. Use the performance data warehouse C. Create DML triggers D. Use the SQL Server 2008 Declarative Management Framework The correct answer is A. This will work on SQL Server 2005 and SQL Server 2008 servers. While Answer D is correct, the DMF will allow you to perform the task at hand only on SQL Server 2008 servers. Answer B has nothing to do with enforcing naming conventions. D will not allow you to perform the task of enforcing naming conventions. 9. You have a database table with a varchar(600) field in it. Most of the records in the table have a null value for this field. How can you save space? A. Move the data into a second table B. Use sparse columns C. Install a third-party tool on the machine to compress the data D. Use the SQL Server 2008 Declarative Management Framework The correct answer is A. Sparse columns will take up less space for varchar columns. Sparse columns will take up less space for most columns, but cannot be used for text, ntext, image, timestamp, user-defined data type, geometry, or geography or varbinary (max) with the FileStream attribute can be sparse. Answer C is incorrect; this is not the best approach. Answer D is incorrect, as the Declarative Management Framework will not save you space. 10. You have a database table with a FileStream field in it. Most of the records in the table have a null value for this field. What s the best way to save space? A. Move the data into a second table B. Use sparse columns C. Use the SQL Server 2008 Declarative Management Framework D. None of the above

6 6 Appendix Self Test Appendix The correct answer is D. Answer A is incorrect; this will not save space. Answer B is incorrect, as sparse columns will take up less space for most columns, but cannot be used for text, ntext, image, timestamp, user-defined data type, geometry, or geography or varbinary (max) with the FileStream attribute can be sparse. 11. You need to store images in for a Web site using SQL Server How can you accomplish this? A. Use a FileStream data type, and the images will be stored on disk B. Use a varchar data type and store the images in that field C. Use an int data type and store the images in that field D. Use an nchar data type and store the images in that field The correct answer is A. The FileStream data type is meant for storing files on disk. You could also store the image in a varbinary field, but moving forward the recommended approach is to use the FileStream data type. Answers B, C, and D all reference data types that cannot be used to store binary data like image files. One approach is to use a varchar field as a pointer to the disk, but this is not recommended after the introduction of the FileStream data type. 12. You are responsible for a system that is used for both online transaction processing (OLTP) and reporting. When reports run on the server, the OLTP process slows way down. How can you allow reports to be run on the server and minimize impact to the OLTP processes? A. Use the Resource Governor B. Use a DDL trigger C. Use a DML trigger D. Use processor affinity masks A is the correct answer. The Resource Governor allows you to assign workloads to different groups, then assign a priority to those groups. Answers B and C are incorrect. Triggers cannot be used for this purpose. Answer C is incorrect. Processor affinity masks cannot be used for this purpose.

7 Self Test Appendix Appendix You are creating an application to track crime in different locations throughout a large city. What data type could prove useful for storing location data (longitude and latitude)? A. Varchar B. int C. Char D. Spatial The correct answer is D. Spatial data types are ideal for this type of data. Answer A could work, but is not ideal. Answers B and C are not ideal for storing this type of information. 14. You are running out of space on the drive used to store backups. All of the servers use the same network location. What can you do to save space with your backups while maintaining the same number of backups? A. Use data compression B. Use compressed backups C. Use full backups D. Use a third-party tool B is the correct answer. Compressed backups take up less space. Answer A is incorrect; this will save space in the data files. Answer C is incorrect; this will not save space. Answer D will work, but it s not the best solution. 15. You need to store sensitive data in your SQL Server database. The application has already been written and works fine. What s the easiest way to do this without having to change your application? A. Modify the stored procedures to use xp_encryptstring B. Use transparent data encryption C. Use a third-party tool D. Use a trigger The correct answer is B. Transparent data encryption enables data to be stored securely by encrypting the database files. Answer A is incorrect, as this is not the best approach. Answer C is incorrect; while there are third-party encryption tools, this is not the best approach. Answer D is incorrect; triggers by themselves are not a correct solution.

8 8 Appendix Self Test Appendix 16. Within your application, you need to log all changes to one table. DDL and DML changes must be logged. What s the best approach to solve this problem? A. Use the built-in auditing capability B. Create a DDL trigger C. Create a DML trigger D. This cannot be accomplished A is the correct answer. SQL Server 2008 has built-in auditing capability. Answers B and C are incorrect as they are not a complete solution. Answer D is incorrect, as this can be accomplished with Answer A. 17. You have a server that supports Hot Add CPU. The current CPU utilization is 95 to 100 percent most of the time. The server is mission-critical and cannot be shut down. SQL Server 2008 Standard Edition is installed. What should you do? A. Use the Hot Add CPU feature to add another CPU B. Use the Hot Add CPU feature to add two CPUs C. Add more memory to the server D. Schedule an outage and add another CPU to the server The correct answer is D. SQL Server 2008 Standard Edition does not support Hot Add CPU, which makes Answers A and B incorrect. Answer C is incorrect the issue is CPU, so adding more memory will in all likelihood not solve the problem. 18. You are contemplating using data compression on a table. You would like to know how much space this will save. How can you determine the savings? A. View the table properties B. Enable compression, then check the table size C. Use sp_estimate_data_compression_savings D. Use sp_check_compression The correct answer is C. sp_estimate_data_compression_savings will help you determine if the table is worth compressing. This procedure accepts five parameters.

9 Self Test Appendix Appendix 9 The two critical parameters Answer A is incorrect; compression information is not shown in the table properties. Answer B will not solve the problem before applying compression. Answer D is incorrect, as there is no stored procedure by that name. 19. You have a server that supports Hot Add Memory. Performance is sluggish, and you believe adding more memory will help. The server is mission-critical and cannot be shut down. SQL Server 2008 Standard Edition is installed. What should you do? A. Use the Hot Add CPU feature to add another CPU B. Use the Hot Add CPU feature to add two CPUs C. Add more memory to the server. D. Schedule an outage and add memory to the server. The correct answer is D. SQL Server 2008 Standard Edition does not support Hot Add Memory, which makes Answer C incorrect. Answers A and B are incorrect the issue is memory, so adding more CPU will in all likelihood not solve the problem. 20. You have a SQL Server 2008 installation, and you want to create a highavailability solution. What are the ideal approach(es) to solve this problem? A. Backup and restore B. Replication C. Mirroring D. Clustering The correct answers are C and D. C and D are automated high-availability solutions. Answer A is not necessarily a good solution as it is not automated. Answer B will create a copy of a database, but will require intervention in order for the replicated database to become the active database.

16 16 Appendix Self Test Appendix Chapter 3: Configuring SQL Server You ve just started as a DBA at a company that has recently installed a dedicated server running both a SQL Server 2008 default instance and the database for the company s ERP system. You want to implement a process to test the database with new SQL Server patches and service packs before they are applied to the live database. There is no budget to buy any new servers, but the existing hardware is under-utilized and you re confident it will suffice for your short-term needs. Which of these options would meet your needs? A. Restore a copy of the live database as test on to its own disk array. Apply patches and service packs to the new database and test them before applying them to the live database. B. Install a named instance for testing. Create a database snapshot on the named instance pointing to the live database on the default instance. Apply patches and service packs to the named instance and test before applying them to the default instance. C. Install another default instance for testing and restore a copy of the live database. Apply patches and service packs to the second instance and test before applying them to the live instance. D. Install a named instance for testing and restore a copy of the live database. Apply patches and service packs to the named instance and test before applying them to the default instance. Correct Answer & Explanation: D. SQL Server patches and service packs are applied at the instance level. Having a separate instance with a copy of the live database is the only way to achieve the requirements. Incorrect Answers & Explanations: A, B, C. Answer A is incorrect because you cannot apply service packs and patches to individual databases. Answer B is incorrect because you cannot create a database snapshot between instances. You have to restore a copy of the database onto the instance. Answer C is incorrect because you can only have one default instance. 2. Last month your company went through an exercise to standardize service accounts while you were on holiday. You ve just restarted SQL Server after applying a service pack, and now the instance won t start. You check the Windows Event Log and see lots of errors about not being able to open the error log. What is the most likely cause?

17 Self Test Appendix Appendix 17 A. The SQL Server Service account was not changed using SQL Server Configuration Manager B. The service pack failed C. Data corruption D. You don t have the right permissions to the error log Correct Answer & Explanation: A. If you don t use the Configuration Manager tool to change the service account, it will not get explicit permissions to the SQL Server directory structure. SQL Server will not start without permissions to create an error log file. Incorrect Answers & Explanations: B, C, D. Answer B is incorrect, although technically feasible; the service pack should have generated errors if there was a problem, and given the scenario it is not the most likely cause. Answer C is incorrect, although technically feasible; given the lack of any other errors and the scenario it is not the most likely cause. Answer D is incorrect because the issue is with the Service Account permissions, not your account. To install the service pack you would have needed full Administrator rights on the server anyway. 3. You have a default instance and a named instance installed on your server. The developers are complaining that they can t connect to the named instance from their workstations using Management Studio anymore. You log on to the server through Terminal Services and can connect to each instance without issue. What could the cause of this behavior be? A. The developers haven t created a SQL Server Alias to the named instance using the Shared Memory protocol. B. The SQL Browser Service has been started. C. The SQL Browser Service has been stopped. D. The IP addresses of the developers workstations have been added to the Exclude list in the TCP/IP properties of the named instance in Configuration Manager. Correct Answer & Explanation: C. By default, named instances used dynamic TCP port allocation, and clients depend on the SQL Browser Service to find the current port. Incorrect Answers & Explanations: A, B, D. Answer A is incorrect because you can t create an alias that uses the Shared Memory protocol, and it can be used only by tools running on the server. Answer B is

18 18 Appendix Self Test Appendix incorrect because the SQL Browser Service being started helps remote connections to named instances. Answer D is incorrect because you cannot exclude IP addresses from connecting to SQL Server using Configuration Manager. 4. Your security administrator has determined that all the SQL Servers in your organization need to listen on nondefault TCP ports, and she doesn t want network users to see the SQL Servers in a browse list. Which two actions would achieve this goal? A. Stop and disable the browser service on each SQL Server B. Use Configuration Manager on each server to change each instance to listen on port C. Use Configuration Manager on each server to change each instance to listen different ports D. Configure the SQL Browser Service to hide each instance E. Enable Show Advanced Options using sp_configure and use the Default TCP port option to configure the port for each instance Correct Answer & Explanation: A and C. Stopping the browser service will stop all instances on that server being browsable. Configuration Manager is the only place you can change the TCP port for an instance. Each instance on a server must listen on a unique port. Answers & Incorrect Answers & Explanations: B, D, E. Answer B is incorrect because configuring each instance with the same port on the same server will prevent all but one instance from working. Answer D is incorrect because you cannot hide an instance using the SQL Browser Service. Answer E is incorrect because Configuration Manager is the only place you can change the TCP port for an instance. 5. The company you work for has just merged with another company that uses Novell NetWare as its network operating system. The new company s developers are struggling to connect to your SQL Server. What could be the problem? A. SQL Server 2008 doesn t support the Banyan Vines protocol. B. You haven t enabled the IPX/SPX protocol. C. You haven t enabled the Banyan Vines protocol. D. SQL Server 2008 doesn t support the IPX/SPX protocol.

19 Self Test Appendix Appendix 19 Correct Answer & Explanation: D. Older versions of Novell NetWare used IPX/SPX as a communication protocol. SQL Server 2008 does not support it. Incorrect Answers & Explanations: A, B, C. Answer A is incorrect. While the statement is true, Banyan Vines has nothing to do with the scenario. Answer B is incorrect because SQL Server 2008 doesn t support IPX/SPX. Answer C is incorrect because Banyan Vines has nothing to do with the scenario. 6. You have just upgraded your databases from a SQL Server 2005 default instance to a SQL Server 2008 named instance called Phobos on a server named MARS. The application that uses the SQL Server sits on its own server, and you ve just found out that you can t change the connection string in the application to point to the new instance. How can you fix it? A. Add a CNAME record on your DNS server for MARS that points to MARS\Phobos B. Install SQL Server Client Tools on the application server and create a SQL Server Alias called MARS that points to MARS\Phobos C. Install SQL Server Client Tools on the application server and create a SQL Server Alias called MARS\Default that points to MARS\Phobos D. Add a PTR record on your DNS server for MARS that points to MARS\ Phobos Correct Answer & Explanation: B. Connection requests from the application to MARS will be redirected to MARS\Phobos without you having to change the connection string. Incorrect Answers & Explanations: A, C, D. Answer A is incorrect because DNS resolves IP addresses, and you still need to connect to same server (MARS). DNS has no awareness of instances. Answer C is incorrect because you connect to a default instance using the servername, not servername\ Default. Answer D is incorrect because DNS resolves IP addresses, and you still need to connect to same server (MARS). DNS has no awareness of instances. 7. You install a default instance of SQL Server 2008 Developer Edition with default configuration options. The developers complain that they can t connect to the server using SQL Server Management Studio. Which of these options is the most likely cause?

20 20 Appendix Self Test Appendix A. A firewall is blocking port B. The SQL Browser Service isn t running. C. The SQL Server tools on the developer workstations haven t been service packed. D. TCP/IP is disabled by default in Developer Edition. Correct Answer & Explanation: D. TCP/IP is disabled by default in Developer Edition, which means that all remote connections will fail. Incorrect Answers & Explanations: A, B, C. Answer A is incorrect. Although this would cause the same issue, all remote protocols are disabled, and that is the most likely cause. Answer B is incorrect because the SQL Server Browser Service isn t required to connect to a default instance using default port Answer C is incorrect. Technically, it may be possible for this to cause an issue, but it is not the most likely cause of the problem. 8. A SQL Server recently suffered from all CPUs running at 100 percent, which you found to be caused by a missing index. You fixed the problem, but you want to stop any new occurrences from saturating all CPUs. Which of these options would achieve this? A. Use sp_configure to set max degree of parallelism B. Use Configuration Manager to configure the SQL Server Service to use fewer CPUs C. Run the Database Tuning Advisor and apply any recommendations D. Use sp_configure to set cost threshold for parallelism Correct Answer & Explanation: A. Setting max degree of parallelism to less than the number of CPUs will prevent SQL Server from running parallel executions across all CPUs. Incorrect Answers & Explanations: B, C, D. Answer B is incorrect; you cannot use Configuration Manager to configure SQL Server CPU usage. Answer C is incorrect because DTA recommendations will only reduce the amount of parallelism that occurs. Answer D is incorrect because cost threshold for parallelism controls how expensive queries must be before being considered for parallelism. 9. A developer has contacted you because he wants to enable AWE memory on his Developer Edition instance, but he says that he can t see the option with sp_configure. What is the most likely cause? A. AWE is not supported with Developer Edition.

21 Self Test Appendix Appendix 21 B. The developer is connecting with a low-privilege user and doesn t have enough permissions. C. He hasn t enabled show advanced options with sp_configure. D. He hasn t enabled /PAE in boot.ini. Correct Answer & Explanation: C. AWE is an advanced option and is only visible when show advanced options has been enabled. Incorrect Answers & Explanations: A, B, D. Answer A is incorrect because AWE is supported with Developer Edition. Answer B is incorrect because low privileges won t reduce what you see with sp_configure. Answer D is incorrect because /PAE won t affect whether or not you can see the AWE option. 10. You re running SQL Server 64-bit and want to make sure that SQL Server doesn t take too much memory. Which of these options would achieve that? A. Set Maximum Server Memory (MB) using sp_configure B. Assign the SQL Service account the Lock Pages in Memory privilege C. Set Maximum Server Memory (MB) using SQL Server Management Studio D. Start SQL Server with the -g switch passing the maximum memory as a parameter Correct Answer and Explanation: A and C. Maximum Server Memory controls how much memory SQL Server will use and can be configured using Management Studio or with sp_configure. B is incorrect because this would make a 64-bit SQL Server use AWE to lock memory pages; it wouldn t prevent it from taking too much memory. D is incorrect because the -g switch controls how much reserved memory SQL Server allocates; it won t prevent it from taking too much. 11. One of your DBAs is setting up SQLMail and has asked you for a license key for Outlook. You suggest that he enable Database Mail instead. Which two of these options are features of Database Mail? A. Received s are stored in msdb. B. It doesn t require a MAPI client. C. It is Windows failover-cluster aware. D. It is available in all SQL Server editions.

22 22 Appendix Self Test Appendix Correct Answer & Explanation: B and C. SQLMail requires a MAPI client like Outlook to run. Database Mail uses SMTP and is failover-cluster aware. Incorrect Answers & Explanations: A, D. Answer A is incorrect because you can t receive s with Database Mail. Answer D is incorrect because Database Mail is not available in SQL Server Express. 12. A business user has just phoned to say that his data wasn t updated overnight. You check SQL Server and see that a SQL Server Agent job that runs a data load failed last night. You want to be automatically notified via if it happens again. Which of these options will provide the most efficient, supported solution? A. Implement SQLMail B. Implement Database Mail C. Install a third-party SMTP mailer D. Implement Service Broker Correct Answer & Explanation: B. Database Mail is fast, efficient, reliable, and supported. It meets the criteria in the scenario. Incorrect Answers & Explanations: A, C, D. Answer A is incorrect because SQLMail is less efficient and reliable than the Database Mail that supersedes it. Answer C is incorrect because a third-party SMTP mailer would be unsupported, and Database Mail is an SMTP mailer. Answer D is incorrect because Service Broker is the messaging engine used by Database Mail. It does not provide facilities on its own. 13. You ve just upgraded to SQL Server 2008 from SQL Server 2000, and you ve dropped SQLMail in favor of Database Mail.

23 Self Test Appendix Appendix 23 Incorrect Answers & Explanations: B, C, D. Answer B is incorrect because SQLMail and Database Mail don t work together. Answer C is incorrect because you can specify multiple SMTP servers. Answer D is incorrect because the question refers to a mail server going down, not Database Mail going down. 14. You ve been investigating deadlocks on your server using trace flag 1222, and you d like to enable it permanently to capture extra information if deadlocks occur again, even if SQL Server gets restarted. What is the easiest way to do this? A. Execute DBCC TRACEON (1222,-1) B. Create a start-up stored procedure containing DBCC TRACEON (1222,-1) and use sp_configure to enable scan for startup procs C. Use Configuration Manager to add T1222 as a start-up parameter for the SQL Server service D. Execute DBCC TRACEON (1222) Correct Answer & Explanation: C. T is a start-up switch that enables the specific trace flag for all connections. Incorrect Answers & Explanations: A, B, D. Answer A is incorrect; although this would enable the trace flag on all connections (-1), it will not persist a service restart. Answer B is incorrect because it is not the easiest method for achieving the goal. Answer D is incorrect because the trace flag will not persist a service restart and would only enable it on the current connection. 15. You ve been told that you need to make your SQL Server compliant with EAL4+. What is the first step you need to do in this process? A. Use sp_configure to enable c2 audit mode. B. Use sp_configure to enable common criteria compliance enabled. C. SQL Server 2008 is automatically EAL4+ compliant. D. SQL Server 2008 does not support EAL4+ compliance.

24 24 Appendix Self Test Appendix to enable Common Criteria Compliance. Answer D is incorrect because SQL Server 2008 supports EAL4+ through Common Criteria Compliance. 16. Some of your full-text indexes are consuming a lot of server resources. You investigate and discover that the index causing the problem is on a text-based field that is updated frequently. You ve spoken to the business, and the updates don t affect their search results. What could you do to reduce the overall impact on the server while keeping the index fairly up-to-date? A. Set change tracking on the index to AUTO B. Move the index to a filegroup on its own drive C. Set change tracking on the index to MANUAL and schedule a nightly population update. D. Set change tracking on the index to OFF Correct Answer & Explanation: C. This will still track changes but switches off auto propagation to the index. A nightly update will process all the tracked changes. Incorrect Answers & Explanations: A, B, D. Answer A is incorrect; change tracking is already at the default setting of AUTO, and that is what is causing the problem. Answer B is incorrect because you want to reduce overall impact, and this option will only directly affect disk i/o. Answer D is incorrect because there is no method specified to keep the index updated. 17. You have installed a default and two named instances called Phobos and Deimos on a server called Mars. How would you connect to each instance? A. Mars, Mars\Phobos, Mars\Deimos B. Mars, Mars1\Phobos, Mars2\Deimos C. Default, Phobos, Deimos D. Default, mars\phobos, mars\deimos Correct Answer & Explanation: A. The default instance accessed by using the servername and each instance is accessed by adding \<instancename> to the servername. Incorrect Answers & Explanations: B, C, D. Answer B is incorrect; Mars1 and Mars2 refer to different servers. Answer C is incorrect because Default is invalid for the default instance and the server is missing from the instance names. Answer D is incorrect because Default is invalid for the default instance.

25 Self Test Appendix Appendix Your developers complain that they can t connect to the server using SQL Server Management Studio. You ve used Terminal Services to log on to the server, and you ve confirmed that TCP/IP is enabled. You now want to test it with a local connection. What should you do? A. Nothing, just connect B. Disable Shared Memory in Configuration Manager C. Move TCP/IP above Shared Memory in the connection protocol order D. Disable Shared Memory using sp_configure shared memory enabled Correct Answer & Explanation: B. Disabling Shared Memory will force SQL Server to use the next protocol to connect which is TCP/IP by default. Incorrect Answers & Explanations: A, C, D. Answer A is incorrect; local connections will use the Shared Memory protocol by default. Answer C is incorrect because Shared Memory cannot be moved in the connection protocol order, only disabled. Answer D is incorrect because the sp_configure option is invalid. 19. You are responsible for a large-capacity server that has a default instance of SQL Server 2008 installed and hosts databases for multiple applications belonging to several of your customers. A new database needs to be moved to the server, which has a different collation, and the collation of TempDB needs to match it. You can t change the collation for your existing TempDB because it will affect all the applications. What could you do? A. Create another TempDB with the right collation and configure the new database to use it B. Configure the database to use a different TempDB on a remote server C. Install a new instance for the database with a default collation the same as the database D. A separate server with a separate instance is the only option Correct Answer & Explanation: C. You can have only one TempDB database per instance, and it might be feasible to install a second instance on a large capacity server. Incorrect Answers & Explanations: A, B, D. Answer A is incorrect; you can have only one TempDB per instance. Answer B is incorrect because you cannot configure to use a remote TempDB. Answer D is incorrect because it isn t the only option.

Jose has ownership of database tables in database A and database B, both of which reside in the same instance of SQL Server where cross database ownership chaining has been enabled. Jose uses a database view in database A to join both tables in order to retrieve the needed data. Jose grants Jack permission to use her database view. What other permissions need to be granted in order for Jack to retrieve data using Jose s view? A. Jack needs to be granted read permissions to the table in database B that is used by the view. B. Since cross database ownership chaining is enabled in this instance, no additional permissions need to be granted. C. The tables used by the view in database A and B need read permissions granted to Jack. D. Jack cannot use Jose s view since she is the owner. Jack will need his own view and permissions. The correct answer is B. With cross database ownership chaining, credentials are only checked on the first object request. Since Jack was granted permission by the object s owner, Jose s credentials will be used to access the tables in database B. Answer A is incorrect since Jack was granted permission to the view by the object owner and cross database ownership chaining was enabled. Jack s credentials would not be checked for accessing the table in database B. In addition, there is no need to permission the database B table to Jack.
