4 1.1 Describe and recognize common virtualization technologies and products and their implications on customer needs A doctor's office has an X-ray machine that saves image files to an HP ProLiant DL580 with a Smart Array storage system configured as a single RAID 5 volume. The Smart Array volume is nearing capacity, but the customer has other servers with storage systems that are not full. The customer wants to add capacity using existing assets without taking the system down or making additional hardware investments. Which storage solution meets the customer requirements? A. RAID 10 migration B. Storage virtualization C. Storage Area Network (SAN) D. Network Attached Storage (NAS) Storage virtualization will meet the customer requirements. The customer can implement storage virtualization by leveraging storage systems on the other servers. A RAID 10 migration will not meet the customer requirements because it will require an investment in hardware and will require taking the system down. SAN and NAS will not meet the customer requirements because using either one will require an investment in hardware. Study Guide 4

5 1.2 Describe the business benefits of Virtualization What are two business benefits of virtualization? (Choose two.) A. Mitigates risk of downtime B. Increases server performance C. Reduces software licensing costs D. Lowers overall power requirements E. Reduces network bandwidth consumption Two business benefits of virtualization are: It mitigates the risk of downtime. It lowers overall power requirements. Virtualization does not increase server performance. With multiple virtual machines running on a physical server, performance may decrease if the server is not sized properly. Virtualization does not reduce software licensing costs. Software installed on both physical and virtual machines must be licensed. Virtualization does not reduce network bandwidth consumption. Study Guide 5

6 1.3 Define cloud and identify and describe various types of cloud services and their implications on customer needs Which product allows you to implement document collaboration, workflow management, and change tracking in a cloud environment? A. WebEx B. LinkedIn C. Carbonite D. SharePoint Online Of the products listed, only SharePoint Online allows you to implement collaboration, workflow management, and change tracking in a cloud environment. WebEx supports collaboration through online meetings, but it does not support workflow management and change tracking. LinkedIn is a tool that you can use to network with other people and participate in special interest groups. You can use Carbonite as an online backup solution Study Guide 6

7 1.4 Describe the business benefits and risks of using cloud services What are two risks associated with using a public cloud service? (Choose two.) A. Lack of scalability B. Data confidentiality C. Lack of customization D. Increased administrative overhead E. Lack of client device interoperability Two risks associated with using a public cloud service are: Data confidentiality The lack of customization You should consider implementing a private cloud to ensure data confidentiality and the ability to customize. Using a public cloud service provides you with scalability by allowing you to pay for delivery of a service instead of investing in your own hardware and software Using a public cloud service tends to decrease, not increase, administrative overhead. Public cloud services support a wide variety of client devices, so lack of interoperability is not a risk. Study Guide 7

9 2.1 Consult with an SMB customer to translate their business objectives into an enabling technology strategy A business is looking for an automated sales solution. The business has sales people who travel frequently to multiple cities. They need to be able to: Communicate with customers by . Create sales invoices in a company database. View and edit the same customer data as the inside sales team. Process customer payments. The business does not have an IT staff. Which services should you suggest? (Choose two.) A. VPN B. Hosted file sharing C. Hosted QuickBooks D. Networked QuickBooks E. Hosted Microsoft Exchange For this business, you should suggest hosted QuickBooks and Microsoft Exchange services. The QuickBooks service will allow the sales people to create invoices, process customer payments, and view and edit customer data. The Microsoft Exchange service will allow them to use to communicate with customers. Because the business does not have an IT staff, you should not suggest a VPN or a networked QuickBooks service. You should not suggest hosted file sharing because this solution does not address any of the stated requirements. Study Guide 9

10 2.2 Gather the customer's technical requirements and assess existing infrastructure Your customer is a small online retailer. The retailer has an in-house server running the following services: Microsoft Exchange Server Public-facing web site and ecommerce solution Internal web-based customer relationship management (CRM) software The customer's DSL connection has a 15 Mbps downlink and 2 Mbps uplink. Recently, orders have gone up significantly, and customers and employees are reporting slow performance. The customer relies on resellers for IT support and has no plans to hire internal IT employees. What is the best solution? A. Upgrade the internal network to 10 Gbps Ethernet. B. Upgrade the DSL line to have more upstream bandwidth. C. Move the company web site and ecommerce solution to a hosting provider. D. Set up a separate server in-house to handle hosting of the company web site and ecommerce solution. The best solution for this situation is to move the company web site and ecommerce solution to a hosting provider. This solution will offload network traffic from the retailer's network and leverage the support services available from the hosting provider. Upgrading the internal network to 10 Gbps Ethernet or upgrading the DSL line to have more upstream bandwidth will not improve performance for the retailer's customers. Because the retailer has no plans to hire internal IT employees, setting up and managing a separate server in-house is not a viable option. Study Guide 10

11 2.3 Design the end-to-end Technical Solution for an SMB customer including on-premises, hosted, and cloud solution components You are assessing whether a cloud or on-premises solution is better for your customer. Match each customer situation with the best solution. Solutions Cloud On-Premises Customer Situations Diversity of client platforms Customer has a data center facility Low IT budget Quick implementation Regulations require data privacy Customer situations for which implementing a cloud solution is best include: A low IT budget The need for a quick implementation A diversity of client platforms Customer situations for which implementing an on-premises solution is best include: The customer has a data center facility Regulatory requirements require data privacy Study Guide 11

12 2.4 Design online presence and hosted services solution elements (incorporating both onsite and cloud components as appropriate) You are meeting with a new customer who has previously registered a domain with Godaddy.com. The customer wants you to get the new domain set up with hosting, so that the web designer can take over. What should you do NEXT? A. Enable DNS. B. Enable SMTP mail for the hosting account. C. Enable a hosting account for the web site. D. Contact the web designer to determine the implementation platform. You should contact the web designer to determine the implementation platform. You need to know the implementation platform before you set up the account at Godaddy.com. You should not enable DNS, enable SMTP mail for the hosting account, or enable a hosting account for the web site until after you contact the web designer. Study Guide 12

13 2.5 Design an end-to-end solution for support/disaster recovery for an SMB customer You are designing a disaster recovery plan for a company that is located in an area that is vulnerable to natural disasters. You want to minimize data loss and maximize availability. Which actions would be important to perform? (Choose two.) A. Identify the systems and applications that are mission critical. B. Design link aggregation. C. Design data storage as 1+0 RAID arrays. D. Identify the storage location for on-site backup tapes. E. Identify the acceptable level of service required in the event of a disaster. To minimize data loss and maximize availability, you should: Identify the systems and applications that are mission critical. Identify the acceptable level of service required in the event of a disaster. Before you can design a recovery plan, you need to determine which systems and applications are mission-critical so you can plan not only for recovery, but also continuity. You need to prioritize the systems and applications according to how important they are to the mission of the organization. Identifying the acceptable level of service required in the event of a disaster helps to identify the measures you need to take to provide that level of service. Study Guide 13

14 2.6 Write and present a solution proposal to the customer decision makers You have met previously with a customer to understand the customer's business needs. You are now proposing a specific solution set to meet those needs. What things should you ask when validating a possible solution set with a customer? (Choose two.) A. Is the timeframe doable? B. Do you have on-site IT staff? C. Is the cost quoted affordable? D. What applications do you currently use? E. How many software licenses do you have? When you are validating the solution with the customer, it is important to validate the proposed schedule and the cost. You would typically ask the other questions when you are gathering information, not when you are validating the solution. Study Guide 14

15 Unit 3 Install, configure, and upgrade end-toend IT solutions for SMB customers 3.1 Implement changes to the existing infrastructure to support solution - including servers, storage, data, network, clients, applications, and users Study Guide 15

16 3.1 Implement changes to the existing infrastructure to support solution - including servers, storage, data, network, clients, applications, and users Your customer has decided to implement cloud-based storage. The requirements indicate that the customer will be storing 100 MB of data per hour. The current network uses 100BASE-TX to the desktop. There is an Internet firewall at the customer's site. The customer has Internet access through a local provider. Which two statements will be true about implementing cloud storage? (Choose two.) A. The cloud-based storage will be easier to expand than local storage. B. The local storage will be easier to expand than cloud-based storage. C. The cloud-based storage will be generally slower than local storage, due to the speed of the Internet. D. The cloud-based storage will be generally faster than local storage, due to the speed of the Internet. Cloud-based storage is easier to expand than local storage. When you have contracted for cloud-based storage, you do not need to purchase hardware and install it to expand the capacity. You can often expand the storage capacity by requesting it online.

17 Unit 4 Optimize and troubleshoot end-to-end IT solutions for SMB customers 4.1 Apply the HP troubleshooting methodology in an end-to-end solution environment 4.2 Troubleshoot common issues in end-to-end solutions for SMB customers 4.3 Optimize common performance issues in end-to-end solutions for SMB customers Study Guide 17

18 4.1 Apply the HP troubleshooting methodology in an end-to-end solution environment A customer has a server that runs two virtual machines: APPSRV and DBSRV. The APPSRV virtual machine has an external network interface and an internal network interface. The DBSRV virtual machine has only an internal network interface. APPSRV runs a client/server application that reads from and writes to a database on DBSRV. The virtual hard disks for each virtual machine are located on separate volumes. The customer reports that when he connects to APPSRV and attempts to insert a record, data is not updated in the database. What should you do FIRST? A. Move the virtual hard disks to the same volume. B. Verify that APPSRV can communicate with DBSRV. C. Verify that the client computer can communicate with DBSRV. D. Change the network interface on DBSRV to an external network interface. Because the application on APPSRV writes to a database that is stored on DBSRV, if a user cannot write to the database, you should check the connectivity between the two virtual machines. You should not verify that the client computer can communicate with DBSRV. The client computer does not need to communicate with DBSRV. APPSRV needs to communicate with DBSRV. Also, because DBSRV only has an internal network interface, it can only communicate with the virtualization server and other virtual machines on that server. You should not change the network interface on DBSRV to an external network interface. The problem is communication between APPSRV and DBSRV, not DBSRV and the client on the external network. Study Guide 18

19 4.2 Troubleshoot common issues in end-to-end solutions for SMB customers A customer has multiple branch offices that connect to a centralized mail server. One branch reports that no users in the office have access. What should you do FIRST to troubleshoot this issue? A. Reboot the mail server. B. Ping the mail server to confirm that it is up and running. C. Confirm that the problem is isolated to that office by calling another remote office. D. Confirm that the user accounts have not been locked because of multiple login retries. You should first confirm that the problem is isolated to that office by calling another remote office. If the problem affects all branches, it is more urgent and requires a more immediate response. Confirming that other offices have normal access also tells you that the mail server is running. You should not reboot the mail server first. Doing so will mean that all users lose access to for a while, so it should not be the first response. The problem could be the connection between the branch and the server, so rebooting the server should wait until the problem has been isolated to the server and you are certain that it needs to be rebooted. After you have confirmed that the problem is isolated to the branch office, you can check for locked out user accounts. However, it seems unlikely that everyone in the branch office got locked out after multiple logon attempts. Study Guide 19

20 4.3 Optimize common performance issues in end-to-end solutions for SMB customers A customer complains that performance of the company's infrastructure that is based on virtual machines in not acceptable. Which HP tool you can use to identify bottlenecks on the host server and a recommendation about how to solve it? A. Resource Monitor B. Performance Monitor C. Insight Diagnostic Online Edition D. Insight Control performance management Insight Control performance management provides information on bottlenecks and instructions about how to solve them. Resource Monitor is a Microsoft Windows tool, not an HP tool. Performance Monitor can provide some information about bottlenecks if you configure it to do so, but it does not provide instructions about how to solve them. Diagnostic Online will not detect performance issues, only hardware problems. ftp://ftp.compaq.com/pub/products/servers/management/releasenotes230.pdf Study Guide 20

21 Unit 5 Administer and manage end-to-end IT solutions for SMB customers 5.1 Add users, groups and profiles on cloud services in addition to local infrastructure Study Guide 21

22 5.1 Add users, groups and profiles on cloud services in addition to local infrastructure You are conducting a security audit for your customer in conjunction with moving to cloud services. You have discovered that the system administrator uses the same password for all services. Some services require more secure passwords than others. Number the web sites below in order from least to greatest password strengths. What is most likely wrong? A. Gmail B. Local newspaper C. ebay seller account D. PayPal business account The order from least to greatest password strengths is local newspaper, Gmail, ebay seller accounts, and PayPal business accounts. A local newspaper web site typically has the least secure requirements for passwords. Gmail, ebay seller accounts, and PayPal business accounts generally have more secure requirements for passwords.
