4 1.1 Describe and recognize common desktop virtualization technologies and products Which phrase best describes a VHD? A. A logical volume B. A dynamic disk C. A basic disk D. A logical disk A virtual hard drive (VHD) is a logical disk created using a virtualization technology such as Hyper-V. Virtual disks are represented by.vhd files. Dynamic and basic disks are physical disks, not logical disks. A volume is a portion of a disk. Study Guide 3

5 1.2 Describe and recognize Mobile Computing technologies and their implications on customer needs You want to ensure that Windows-based mobile clients for one of your customers receive timely operating system updates. Some clients rarely connect to the internal business network. What should you use? A. Windows Server Update Services (WSUS) B. Configuration Manager C. Windows Update Agent (WUA) D. Systems Management Server (SMS) You should use WUA to update the mobile clients. WUA contacts the Microsoft Windows Update Web site directly and checks for updates. You can control whether or not the updates are downloaded and installed automatically for each client on an individual basis. Network server based solutions, including WSUS, Configuration Manager, or SMS, should not be used because some of the clients rarely connect to the network. This means that the clients would not receive timely updates. With WSUS, updates are downloaded to one central server. An administrator can then select which updates will be installed on client computers. In a routed network, you can set up local update servers that receive updates from the central server and pass them on to clients. Configuration Manager was created as a replacement for SMS. It is designed to manage network clients, including deploying updates, but requires the client computers to be connected to the network. Configuration Manager works with WSUS and receives updates from a WSUS server. SMS can be used to deploy updates, but the process is somewhat manual. You must download the updates and make them available from the SMS server, then configure deployment to client computers. Study Guide 4

6 1.3 Describe and recognize traditional PC technologies and their implications on customer needs How many peripherals per bus can Small Computer System Interface standard One (SCSI-1) support? A. 8 B. 7 C. 4 D. 16 SCSI-1 supports a computer and 7 additional peripherals per bus. SCSI is a set of standards relating to physically connecting computers and peripheral devices. This is a standard relating to the interoperability of conforming devices on a parallel interface. Like all standards in the industry, SCSI has evolved through the years including changes in transfer speeds, cables, and interfaces. Although SCSI-1 supports a total of 8 devices, the question asks for the number of other peripherals, so it is assuming that one ID is already in use. Fast-Wide SCSI supports 16 IDs (15 peripheral devices). Ultra SCSI supports 4 IDs when deployed at a length of 3 meters. Study Guide 5

7 1.4 Describe and recognize thin client technology and solutions You need to centrally deploy an application that is updated often for one of your customers. You also need to allow Windows-based thin client computers from multiple locations to access the application remotely. What should you use? A. APP-V B. System Center Configuration Manager C. Remote Desktop Services D. Server Manager You should use Remote Desktop Services. Remote Desktop Services provides session virtualization and allows you to deploy applications to remote client computers. A RemoteApp can be deployed to a Remote Desktop (RD) Session Host server and then remotely accessed by client computers. Remote Desktop Services also allows you to deploy a virtual desktop that can be accessed by remote client computers. You should not use Microsoft Application Virtualization (APP-V). APP-V provides application virtualization by isolating applications and providing application-to-application compatibility. You would use APP-V to allow users to access an application that is not compatible with another application or a previous version of the same application. You should not use System Center Configuration Manager (SCCM). SCCM is a tool that you can use to centrally manage your IT infrastructure. You can use it to deploy and update servers, clients, and other devices more efficiently. You should not use Server Manager. Server manager allows you to remotely manage a Windows 2008 server from a Windows 7 client computer. Study Guide 6

8 1.5 Describe and recognize cloud technology as it relates to client solutions Which Windows technology allows you to upload files to cloud storage and then access the files via the Internet? A. Windows Server Update Services B. Windows Live SkyDrive C. BitLockerToGo D. Sync Center Windows Live SkyDrive allows you to upload files to cloud storage and then access the files via the Internet. You can grant others the ability view uploaded files. You can also use Windows Live Mesh to synchronize files stored in the cloud. Windows Server Update Services (WSUS) is used to deploy updates to client computers connected to a network. With WSUS, the updates are downloaded directly from Microsoft to a WSUS server and can then be centrally managed, approved, and applied. BitLockerToGo is used to encrypt data stored on removable storage devices. It does not allow you to upload files to cloud storage. Sync Center is used to automatically synchronize offline files and folders between your desktop and laptop. It allows you to configure, manage, and monitor synchronization of files. You can access Sync Center via Control Panel or through Windows Mobility Center. Study Guide 7

9 Unit 2 Plan and design client solutions for SMB customers 2.1 Consult with an SMB customer to assess their business and technical needs and create a plan for a client solution 2.2 Design a client solution to meet the customer needs identified in the planning stage Study Guide 8

10 2.1 Consult with an SMB customer to assess their business and technical needs and create a plan for a client solution Your customer uses a laptop computer at home and at work. The computer is running Windows 7. It is configured as a domain member at work. She wants to access a HomeGroup on her home network. What are the limits on a domain member computer joining a HomeGroup? A. The work laptop cannot provide users with access to its files or printers. B. The work laptop cannot join the HomeGroup. C. She will not be able to modify files stored on computers in her HomeGroup. D. She cannot connect to other computers in the HomeGroup. The work laptop cannot provide users with access to its files or printers. Users cannot access files or printers on the work laptop because it is a member of a domain. She can join the HomeGroup and access resources from other computers, but cannot share resources from the domain-member computer. When she joins the HomeGroup, Windows 7 will automatically try to connect to the other computers in the HomeGroup. Whether or not she can modify files shared to the HomeGroup depends on how the files are shared. A user can choose to share files as read/write or as read-only. Study Guide 9

11 2.2 Design a client solution to meet the customer needs identified in the planning stage You need to protect the data on a USB drive for a customer who wants to require a smart card to unlock access to the data. The USB drive is used by employees who use Windowsbased computers. What should you use? A. Encrypting File System B. NTFS partition C. BitLocker Drive Encryption D. Group Policy You should use BitLocker Drive Encryption. BitLocker is supported for internal and external storage devices. You can configure BitLocker to require a password or a smart card to unlock access to the data on the drive. You should not use Encrypting File System (EFS). EFS is a method for encrypting data. EFS requires the NTFS file system, which is not supported on a USB drive. You should not use an NTFS partition. NTFS is not supported on a USB drive. You should not use Group Policy. You can use the Local Group Policy Editor to require BitLocker Drive Encryption on any storage device interacting with the computer, but it cannot be used to apply BitLocker to a storage device.

12 Unit 3 Install, configure, startup, and upgrade client solutions for SMB customers 3.1 Create pre-installation checklist 3.2 Set up a new PC (hardware) 3.3 Install the OS (operating system) 3.4 Set up a new mobile device 3.5 Set up a thin client Study Guide 11

13 3.1 Create pre-installation checklist You need to ensure that no system compatibility issues exist for your customer's current Windows Vista computer that would prevent successfully installing and running Windows 7 Which tool can you use? A. Upgrade Advisor B. Device Manager C. System Configuration D. Windows Update You can use Upgrade Advisor to ensure that no system compatibility issues exist with your current Windows Vista computer before installing Windows 7. Upgrade Advisor scans the current system for compatibility issues that might prevent a successful upgrade to Windows 7. You cannot use Windows Update. Windows Update allows you to download and install operating system updates and security fixes, not to check for upgrade compatibility issues. You cannot use Device Manager. Device Manager can be used to install and manage device drivers and roll back to a previous version of a device driver. You cannot use System Configuration. Msconfig.exe, also known as System Configuration, is a graphical tool that you can use to customize the boot process and which applications are automatically loaded when the computer is restarted. You can enable or disable startup items and explicitly control which applications are loaded at startup. Study Guide 12

14 3.2 Set up a new PC (hardware) You are planning to deploy the 64-bit version of Microsoft Windows 7 Ultimate to five computers at a customer's site. The computers have the following configuration: x64 processor 1 GB of RAM 200-GB hard disk DirectX 9 graphics device with WDDM 1.0 Applications that will be installed after the operating system installation require 100 GB of disk space. You need to ensure that users have at least 50 GB of disk space available for data files. You need to identify the necessary hardware upgrades to the computers to meet the minimum system requirements. What component or components must be upgraded? A. RAM B. RAM and hard disk C. Hard disk and graphics card D. Hard disk You need to upgrade the RAM. The 64-bit version of Windows 7 requires a 64-bit processor, 2 GB of RAM, 20 GB of hard disk space, and a DirectX 9 graphics device with WDDM 1.0 or higher. The computers only have 1 GB of RAM, so the RAM must be upgraded. You do not need to upgrade the hard disk space. The operating system will use 20 GB of disk space. Therefore, the total disk space used by operating system and applications is 120 GB, leaving 80 GB for the paging file and data files. You do not need to upgrade the graphics card. The graphics card meets the minimum requirement. Study Guide 13

15 3.3 Install the OS (operating system) You need to install Windows 7 on a customer's netbook computer, which does not have a DVD drive. You want to install Windows 7 using a USB device. What should you do FIRST? A. Format the USB device as FAT32. B. Run Diskpart and clean the USB device. C. Create a primary partition on the USB device. D. Copy the contents of the Windows 7 DVD installation media to the USB device. First, you should run Diskpart and clean the USB device. After cleaning the device, you can create a primary partition, make that partition active and format it as FAT32, assign it a drive letter, copy the contents of the Windows 7 DVD installation media to it, and run the install from the USB device. You should not format the USB device as FAT32 first. You should first clean the USB device using Diskpart, create a primary partition on it, and make that partition the active partition. You should not create a primary partition on the USB device first. You should first clean the USB device. You should not copy the contents of the Windows 7 DVD installation media to the USB device first. You should first clean the USB device, create a primary partition, make the partition active, format the USB device as FAT32, and assign it a drive letter. Study Guide 14

16 3.4 Set up a new mobile device You are configuring networking for a Windows 7 mobile client at a customer's site. You want the Windows 7 client to connect to a wireless access point (WAP) that does not broadcast its service set identifier (SSID). You need to minimize the possibility of compromising network security. What should you do? A. Configure the network properties to connect automatically to the WAP when in range. B. Configure the network properties to connect automatically to the WAP when in range and connect even if the network is not broadcasting. C. Manually connect to the network listed as Unnamed Network and enter the SSID when prompted. D. Modify the WAP to have it broadcast its SSID. You should manually connect to the network listed as Unnamed Network and enter the SSID when prompted. This solution ensures that the WAP is sent probe packages only when the client connects, minimizing the possibility of compromising the SSID. Configuring a WAP to not broadcast its SSID is not a reliable security measure. Even though the WAP is not regularly broadcasting its SSID, it will send its SSID as the response to a probe by a wireless client. Wireless clients configured for automatic connection will probe the WAP every 60 seconds, increasing the possibility that the SSID could be detected. You should not configure the network properties to connect automatically to the WAP when in range. This setting is used to automatically connect to wireless networks that broadcast their SSIDs. You should not configure the network properties to connect automatically to the WAP when in range and connect even if the network is not broadcasting. This will cause the WAP's SSID to be listed as an available network and will cause the WAP to be probed regularly, potentially exposing it to unauthorized users. You should not modify the WAP to have it broadcast its SSID. This would make the WAP readily visible to any client in range. Even though not broadcasting the SSID is not a reliable security measure, broadcasting the SSID is even less secure. This is because broadcasting the SSID announces the existence of the WAP whether or not any valid clients are attempting to connect to the WAP. Study Guide 15

18 3.5 Set up a thin client Your customer has a new HP Compaq MultiSeat Desktop computer. He wants you to set it up to support eight HP t150 Zero Client for MultiSeat stations. You need to ensure that the data on USB devices attached to each station is available only to the user of that station. Which operating system (OS) should you install on the desktop computer to support these thin clients? A. Microsoft Windows MultiPoint Server 2010 Essential version B. Microsoft Windows MultiPoint Server 2011 Essential version C. Microsoft Windows MultiPoint Server 2010 Extended version D. Microsoft Windows MultiPoint Server 2011 Extended version To support this configuration, you should install Microsoft Windows MultiPoint Server 2011 Extended version. This OS supports up to 10 stations and ensures that data on any USB device attached to a station is available only to the user of that station. You should not install Microsoft Windows MultiPoint Server 2010 Essential version or Microsoft Windows MultiPoint Server 2011 Essential version. These versions only support up to four t150 stations. You should not install Microsoft Windows MultiPoint Server 2010 Extended version. This version allows users at each station to access data on a USB device on other stations. Study Guide 17

19 Unit 4 Troubleshoot and perform repair/replacement procedures for client solutions for SMB customers 4.1 Troubleshoot common client issues using the HP 6-step troubleshooting methodology 4.2 Describe how to best use support resources Study Guide 18

20 4.1 Troubleshoot common client issues using the HP 6-step troubleshooting methodology You recently upgraded a customer's computer to Windows 7, and now one of the applications is not running properly. What should you attempt FIRST to correct the problem? A. Modify the Compatibility mode of the application. B. Create a shim for the application. C. Uninstall and reinstall the application. D. Run Application Compatibility Manager. You should modify the Compatibility mode of the application. The Compatibility tab in the application's Properties dialog box has a Compatibility mode option that you can set to allow an application to run in an environment that emulates a previous Windows version. You should not create a shim for the application. A shim is a piece of code that translates code in an incompatible application to code that is compatible with Windows 7. Developing a shim would require much more effort. Therefore, it would be best to first modify the Compatibility mode of the application. You should not uninstall and reinstall the application because this would most likely not resolve issues relating to application compatibility. You should not run Application Compatibility Manager (ACM). ACM is used to determine whether applications are compatible prior to an upgrade to Windows 7. Windows Study Guide 19

21 4.2 Describe how to best use support resources Your customer has a variety of HP computers and peripheral devices that are all under warranty. You plan to use the online diagnostic tools available through HP Instant Support Professional Edition to resolve issues that the customer reports to you. For which three products can you use the online diagnostic tools? (Choose three.) A. HP desktop computers B. HP BladeSystem servers C. HP printers D. HP storage systems E. HP notebook computers You can use the online diagnostic tools for HP desktop computers, HP printers, and HP notebook computers. HP Instant Support also includes Chat support for products that are under warranty. You cannot use the online diagnostic tools available through HP Instant Support Professional Edition for HP BladeSystem servers. For these servers, HP offers the HP Proactive BladeSystem Service. You cannot use the online diagnostic tools available through HP Instant Support Professional Edition for HP storage systems. For these systems, you can use HP Insight Remote Support, which is included with an HP warranty and with the HP Care Pack Service. Study Guide 20

22 Unit 5 Perform administrative and operational tasks 5.1 Perform change management and version control 5.2 Perform backups 5.3 Perform administrative and maintenance tasks Study Guide 21

23 5.1 Perform change management and version control Your customer has run out of space on a partition of a Linux-based client computer. You plan to move data from the partition to a new partition, and you want to prevent the need to reconfigure existing applications with the new data path. What type of link should you create? A. hard B. alternate C. symbolic D. shadow A symbolic link consists of text that is interpreted and followed as a path to another file or directory. In this scenario, you would move the data off the full partition and create a symbolic link to map the old path to the data to the new path, thus ensuring that applications can continue to locate the data they require. Symbolic links are also useful in situations where a binary expects a configuration file at /etc/app.conf but you place the configuration file in /tmp/app.d/app.conf instead. In this scenario, you could create a symbolic link using the command: ln -s /tmp/app.d/app.conf /etc/app.conf You use a hard link to define a name for a file that is different from the original file name, in essence giving the file multiple names, each of which can be in a separate directory on the same file system as the directory in which the file was originally created. Each name refers to the same file. A symbolic link is also referred to as an alias, not an alternate. A shadow is used in the OS/2 operating system similar to the way in which a symbolic link is used in Linux. Study Guide 22

24 5.2 Perform backups You are preparing to make several changes to a computer running Microsoft Windows 7. You need to be able to quickly revert to the current registry settings. You want to minimize the effort and hard disk space required to accomplish this. What should you do? A. Create a backup task. B. Create a file backup. C. Create a system restore point. D. Create a system image. You should create a system restore point. A system restore point lets you quickly restore registry settings, as well as other settings used by the Windows operating system. System restore requires minimal storage space compared to other backup methods. One potential drawback of system restore, in some situations, is that it does not have any affect on personal files. You should not create a system image. This is a full backup of the computer, including the operating system, installed applications, personal files, and configuration settings. You would be able to recover from this image, but it requires more space than creating a system restore point. The hard disk file system is not specified in this question, but the system image can be used only with partitions formatted with the NTFS file system. You should not create a file backup. A file backup can back up operating system information, but requires more effort that a system restore point because you would need to specify the files and folders to back up. This would also require an understanding of system configuration and how it is stored on the hard disk. You should not create a backup task. This is a way of specifying file backups to run periodically, but does not necessary back up any data when the task is first created. Study Guide 23

25 5.3 Perform administrative and maintenance tasks You need to customize the boot process and selectively control which applications automatically load when a customer's Windows 7 computer restarts. Which tool should you use? A. Device Manager B. System Configuration C. System Center Configuration Manager D. System Information You should use System Configuration (Msconfig.exe). System Configuration is a graphical tool that you can use to customize the boot process and which applications are automatically loaded when the computer is restarted. You can enable or disable startup items and explicitly control which applications are loaded at startup. You should not use Device Manager. Device Manager is used to view and manage device properties and device drivers. You can use Device Manager to install or update device drivers, roll back device drivers, and troubleshoot devices and device driver problems. You should not use System Center Configuration Manager (SCCM). SCCM is a tool that you can use to centrally manage your IT infrastructure. You can use it to more efficiently deploy and update servers, clients, and other devices. You should not use System Information (Msinfo32.exe). System Information can be used to view detailed information about a computer system, such as details about the hardware and software that is installed. Study Guide 24
