Chapter 6. Managing Virtual Machines > Answers to Review Questions

6.6. Answers to Review Questions

  1. B. You can enter cost center values to help you track resources used. You can then give this information to a cost center so they can calculate a charge for the use of these virtual machines.

  2. C. Checkpoints are a way to temporarily save your virtual machine. This is a great way to have recoverability if you need to load software or do testing. Backups would also work here, but a backup is a longer process and much more complex. You would not want to move or save the virtual machine to another Hyper-V server, and virtual machines can't automatically recover.

  3. C. The Custom tab fields give you 10 custom fields that you can configure to be anything that your organization needs including departments and geographic location.

  4. B. The Migrate link is the way to move a virtual machine from one Hyper-V server to another. You can migrate a virtual machine by clicking the Migrate link in the Actions section.

  5. D. The Priority section gives you the ability to assign a virtual machine a higher priority to the host machine's CPU. There are four priority settings that you can choose from: High, Normal (the default), Low, and Custom.

  6. C. The self-service role allows an administrator to give users the right to create and manage their own virtual machines. Users can create and manage their own virtual machines by using the self-service web portal.

  7. B. The biggest advantage of IDE compared to SCSI is that IDE can be booted from. You can't boot the machine up from a SCSI drive. SCSI drives have greater performance than IDE and they are primarily used for storage. Hyper-V virtual machines can use SCSI devices, but they can't be booted from SCSI devices.

  8. A. Checkpoints are a quick and easy way to set up saved states at a given period in time. Checkpoints are used for recoverability from a failure or error. Create checkpoints before you do any major updates or improvements to the Hyper-V virtual machines.

  9. C. The Reserves tab allows an administrator to reserve resources for the operating system on the host. The options allow you to set aside resources for the Windows Server 2008 operating system. As you are creating and running virtual machines, these virtual machines will take resources away from the host operating system. By setting aside resources just for the host operating system, you guarantee that the host operating system will continue to function properly.

  10. B. When configuring the virtual machine, you can specify how you want the virtual machine to react when the physical system stops. There are three options that you are allowed to choose from: Save State, Turn Off Virtual Machine, and Shut Down Guest OS. Save State guarantees that when the host system shuts down, the virtual machine will be saved.

  11. A. The Remote tab allows you to set up the port that enables remote connections to the virtual server. Remote connections to the virtual server are enabled by default, but you may need to configure your port number.

  12. B. Templates allow you to create multiple virtual machines with the same hardware and software settings. Using templates allows you to quickly create a virtual machine without the need to create the virtual machine from scratch.

  13. A, B, D. All of the answers are correct except for C. Administrator passwords should not be blank on a server. The administrator password should be blank in the template but servers should never have blank administrator passwords.

  14. B. This is a server that will contain your library shares for all of your Hyper-V servers to use. After you add the new library server to the SCVMM utility, you need to share folders on that server. After the folders are shared, you add a share into the SCVMM utility. This will then give you the ability to place virtual machines onto the shared server.

  15. A. Hardware profiles can be used for a new virtual machine or a virtual machine template. Hardware profiles allow you to preset the hardware configuration in advance, and then you can choose these hardware profiles during the creation of the virtual machines.

  16. B. By choosing the Always Automatically Turn On The Virtual Machine radio button, you ensure that whenever the physical machine starts, the virtual machine will automatically start. This guarantees that if the machine reboots or restarts, the virtual machine restarts.

  17. C. You'd use the Guest Operating System page if this template is going to be a member of the workgroup or domain. Here you would also set the Administrator's password and the user credentials needed to properly add the computer to the domain.

  18. A. In the Network Adapter section is the Ethernet (MAC) Address settings. This section allows you to configure a MAC address for the virtual network adapter. You can dynamically configure the MAC address, which means that the system will assign a MAC address to the virtual network adapter, or you can manually configure a MAC address.

  19. A, B, C, D. All of the answers are part of Integrated Services. Integrated Services are the extra services that you want your virtual machine to complete while running in Hyper-V. There are five services that you can choose for your virtual machine: Operating System Shutdown, Time Synchronization, Data Exchange, Heartbeat, and Backup (Volume Snapshot).

  20. A. Image libraries are an easy way to organize your virtual machines. After setting up a library server, you just share the folders where you want to place the virtual machines.
