• Question 41:

  Part of your design includes updating VMware tools and virtual hardware to a newly updated vSphere 5.1 architecture. What is the best method for updating tools and hardware?

  A. Manually update each virtual machine

  B. Don't bother updating the VMs; the new version of hardware and tools are not necessary

  C. Use Update Manager to update all the virtual machines at once

  D. Use Update Manager to help update the virtual machines in groups, as maintenance windows allow

• Question 42:

  Which of the following is a good way to set a memory reservation?

  A. Use reservations on all virtual machines to ensure that they are all guaranteed memory.

  B. Set a reservation to a virtual machine's available memory to avoid creating a swap file.

  C. Never set a reservation on a virtual machine.

  D. Set a reservation only on a critical virtual machine, with the reservation set to the minimum amount of memory needed for acceptable performance.

  Correct Answer: D

• Question 43:

  While viewing the ESXi host resource tab, you notice that you have 1 GB of available memory. You attempt to turn on a virtual machine with a 1 GB reservation, and the virtual machine will not power on. What is preventing the virtual machine from powering on?

  A. There are too many virtual machines on the host.

  B. For a virtual machine to start, there must be enough available memory for the reservation and memory overhead.

  C. A reservation was set too high.

  D. A CPU reservation was not set.

  Correct Answer: C

• Question 44:

  You have been tasked with creating a new domain controller in the vSphere environment to replace the physical domain controller. You are trying to determine how much memory to give the virtual machine. What is your best option?

  A. Create the VM to match the memory of the domain controller

  B. Give the VM as much memory as possible to ensure optimal performance

  C. Read the vendor documentation and base your memory setting on that

  D. Look at the long-term memory metrics of the server and have the memory setting match the maximum memory used by the domain controller

  Correct Answer: D

• Question 45:

  A. True

  B. False

  Correct Answer: A

• Question 46:

  When is it appropriate for a virtual machine to use the virtual machine swap file?

  A. Always

  B. Never

  Correct Answer: B

• Question 47:

  The swap file must always be stored with the other virtual machine files.

  A. True

  B. False

  Correct Answer: B

• Question 48:

  A. comprehensive

  B. predictive

  C. adaptive

  D. literal

  Correct Answer: C

• Question 49:

  C. Adaptive

  D. Literal

  Correct Answer: B

• Question 50:

  During the design phase, one of the constraints listed is that because the organization is already using SQL Server 2008 in-house, a SQL Server database would have to be used for the vCenter Server. Because of the constraint, ______________.

  A. the organization would have to use VCSA since it supports SQL Server

  B. the organization would have to use the Windows versions of the vCenter Server, but the database would have to be internal to the vCenter Server

  C. either the VCSA or the vCenter Server can be used

  D. the Windows version of vCenter Server would have to be used because VCSA does not support SQL Server

  Correct Answer: D
