A. It will shut down.
B. Nothing.
C. It will be powered off.
D. It will be suspended.
C. The Vmware Tools are required for a proper shutdown of the guest OS, so the virtual machine without the Vmware Tools would be powered off.

- When implementing VMware FT, what is the overhead percentage that is required?
A. 5 to 10 percent
B. 10 percent
C. 5 to 20 percent
D. 20 percent
C. FT has an overhead of 5 to 20 percent that must be accounted for. This is for additional CPU, RAM, disk IO and network IO.
- Which of the following schedulers exist in a DRS-enabled cluster? (Choose two.)
A. Priority scheduler
B. Global scheduler
C. Entitlement scheduler
D. Local Scheduler
B and D. Enabling DRS on a cluster will create a second layer of scheduling architecture to go along with the local scheduler on each ESXi host. This second scheduler is called the global scheduler.
- Which of the following statements best describes the Expandable Reservation parameter?
A. The expandable Reservation parameter can be used to allow a child resource pool to request resources from its parent.
B. The expandable Reservation parameter can be used to allow a child resource pool to request resources from its parent or ancestors.
C. The Expandable Reservation parameter can be used to allow a parent resource pool to request resources from its child.
D. The Expandable Reservation parameter can be used to allow a parent resource pool to request resources from a sibling.
B. Selecting the expandable reservation allows a child resource pool to requires resources from its parent or ancestors.
- When raising the EVC mode for the cluster, which of the following statements is true? (Choose two.)
A. Raising the EVC mode for cluster involves moving from a greater feature set to a lower feature set.
B. Raising the EVC mode for cluster involves moving from a lower feature set to a great feature set.
C. Running virtual machines will need to be powered off during this operation.
D. Running virtual machines may continue to run during this operation.
B and D. Raising the EVC mode for cluster involves moving from a lower feature set to a greater feature set. Virtual machines can continue to run during this operation.
- When using vMotion to migrate a virtual machine, the option to select a resource pool was not available for the destination. What could be a reason for this?
A. The VM has an individual memory reservation set.
B. vMotion does not allow this operation.
C. Changing resource pools is not allowed.
D. No resource pools exist in the destination.
D. If resource pools do not exist in the destination, the Migrate Virtual Machine Wizard will not offer you the option to select a resource pool.
- In which of the following automation levels will vCenter Server inform of suggested virtual machine migrations and place the virtual machines on ESXi hosts at VM startup?
A. Manual
B.Partially automated
C. Fully automated
D. None of these
B. In the partially automated automation level, vCenter Server will inform of suggested virtual machine migrations and place the virtual machines on ESXi hosts at VM startup.
- Which of the following admission control policies will result in an ESXi host in the cluster that is unable to run virtual machines until a failover situation occurs?
A. Host failures the cluster tolerates
B. Percentage of cluster resources reserved as failover spare capacity
C. Specify failover hosts
D. None of these
C. When choosing the specify failover hosts admission control policy, no virtual machines can be powered on when they are on the specified failover hosts, unless an HA event has occurred.
- Which of the following are configurable resource pool attributes? (Choose all that apply.)
A. Shares
B. Reservation
C. Priority
D. Name
A, B and D. Resource pools allow shares, reservations, and limits to be configured, and the resource pool name can be changed.
- A master host has stopped receiving heartbeats from a slave host. What are the possible conditions that the slave host could be in? (Choose all that apply.)
A. Failed
B. Unprotected
C. Isolated

- Which of the following can be used to enable and disable VMware FT for a virtual machine that contains a single eager zeroed thick-provisioned disk? (Choose all that apply.)
A. The vSphere Client for the powered-on virtual machine
B. The vSphere Client for the powered-off virtual machine
C. The vSphere Web Client for the powered-on virtual machine
D. The vSphere Web Client for the powered-off virtual machine
A, B, C and D. Both clients can be used to enable FT. The power state of the VM is irrelevant, since the VM’s virtual disk files are already eager zeroed thick provisioned.
- You need to test the FT configuration in your environment. Which of the following approaches is both supported and noninvasive?
A. Pull the power cables from an ESXi host that is running VMs with FT enabled.
B. Use the Web Client and right-click the secondary virtual machine Choose the Delete From Disk option.
C. Put an ESXi host with FT VMs running on it in maintenance mode.
D. Use the Web Client and right-click a virtual machine that has FT enabled on it. Choose the Fault Tolerance Test Failover option from the context menu that appears.
D. The Fault Tolerance Test Failover option is both noninvasive and fully supported.
- You want DRS to use the most aggressive setting possible for the migration threshold. How do you accomplish this?
A. Move the slider for the automation level to the far left in the DRS settings.
B. Move the slider for the migration threshold to the far left in the DRS settings.
C. Move the slider for the automation level to the far right in the DRS settings.
D. Move the slider for the migration threshold to the far right in the DRS settings.
D. The migration threshold is configured beneath the automation level settings of the DRS cluster. Moving the slider to the far right will set the migration threshold to Aggressive.
- Which of the following is a use case for VMware FT? (Choose all that apply.)
