• Question 156:

  Which two supported tools can be used to upgrade virtual machine hardware? (Choose two.)

  A. vSphere Web Client

  B. vSphere Update Manager

  C. vmware-vmupgrade.exe

  D. esxcli vm hardware upgrade

  Correct Answer: AB

  Vmware offers the following tools for upgrading virtual machines:

  vSphere Client

  Requires you to perform the virtual machine upgrade one step at a time, but does not require vSphere Update Manager.

  vSphere Update Manager

  Automates the process of upgrading and patching virtual machines, thereby ensuring that the steps occur in the correct order. You can use Update Manager to directly upgrade virtual machine hardware, Vmware Tools, and virtual appliances.

  You can also patch and update third-party software running on the virtual machines and virtual appliances.

• Question 159:

  Refer to the Exhibit.

  

  An administrator recently created a Virtual SAN but no Storage Policies were defined. A few virtual machines were deployed to this cluster. The administrator analyzes the default Virtual SAN policy as shown in the Exhibit. Based on the exhibit, which two statements are true? (Choose two.)

  A. Losing one cluster node will not affect data availability.

  B. Losing one Hard Disk in a cluster node will not affect data availability.

  C. Creating a virtual machine Swap file will fail if it violates default storage policy.

  D. Creating a virtual machine will succeed even if it violates default storage policy.

  Correct Answer: AB

  The Virtual SAN policy shows that the tolerate level is on so losing a cluster node will not affect data availability. Same is the case with hard disk in cluster node. Losing it will not affect data availability.

• Question 160:

  Which statement is true for the Path Selection Plug-In VMW_PSP_MRU?

  A. VMW_PSP_MRU is default for a majority of active-active and active-passive arrays.

  B. VMW_PSP_MRU will remain on the selected path even if the state were to change.

  C. VMW_PSP_MRU is recommended for Virtual SAN.

  D. VMW_PSP_MRU will have no preferred path setting for the Plug-In.

  Correct Answer: D

  The host selects the path that it used most recently. When the path becomes unavailable, the host selects an alternative path. The host does not revert back to the original path when that path becomes available again. There is no preferred path setting with the MRU policy. MRU is the default policy for active-passive storage devices.
