VMware Certified Professional 5 – Data Center Virtualization for Instructors

Question No: 161 – (Topic 4)

The RDP performance for a virtual machine on an ESXi 5.x host appears to be degraded.

What are two possible causes of the problem? (Choose two.)

  1. The virtual machine has a high Ready value.

  2. The virtual machine#39;s network adaptor is not configured to Connect at power on.

  3. The virtual machine#39;s network adaptor is not configured as connected.

  4. The virtual machine is on a physical network that has become saturated.

Answer: A,D Explanation:

The virtual had a high ready value and it is on a physical network that has become saturated. That’s why the RDP performance becomes degraded.

Users are having difficulty accessing a Web server since a new Web application was configured in a virtual machine running on sc-titanium03.vmeduc.com. The web server has been assigned 1 vCPU. The vSphere Client reports the error shown in the exhibit. DRS is set to fully automated mode, but the problem has not resolved.

Which action can resolve the issue?

  1. Set a CPU reservation for the web server VM.

  2. Manually move the Virtual Machine using high priority vMotion.

  3. Configure the DRS Migration Threshold to Aggressive.

  4. Set CPU affinity for the virtual machine.

Answer: A

Question No: 163 – (Topic 4)

Users are complaining that they cannot access their files on a file server virtual machine. The vSphere Client shows that a triggered alarm stating disk latency is beyond the default threshold for the datastore where the file server virtual machine is located. The path selection policy has been set by the ESXi host to Fixed with default path settings.

Which two options could be used to increase performance of the file server virtual machine? (Choose two.)

  1. Use disk shares to increase the priority for the datastore housing the file server virtual machine.

  2. Use vMotion to relocate the VM to an ESXi host with lower HBA saturation.

  3. Change the path selection policy to Round Robin.

  4. Change the path selection policy to Most Recently Used (MRU).

Answer: B,C Explanation:

To increase the performance of the file server virtual machine, you can use vMotion to relocate VM to an ESXi host with lower HBA saturation. You also need to change the path selection policy to round robin.

Question No: 164 – (Topic 4)

A new ESXi 5.x host is set up with two virtual machines. A memory limit is applied so that users will have predictable performance as virtual machines are added to the host.

What is the effect of applying a memory limit to these virtual machines?

  1. No physical memory will be granted above the limit, but VSWP can be used.

  2. No physical memory will be granted above the limit, unless expandableVM shares are set to high.

  3. Physical memory will be granted above the limit under normal conditions. Disk pages will be used if contention occurs.

  4. Physical memory will be granted above the limit under normal conditions, unless physical memory runs out.

Answer: A

Question No: 165 – (Topic 4)

Which two options cannot be edited if vApp Options is disabled in the Options tab of a virtual machine that is part of a vApp? (Choose two.)

  1. Transient IP Addresses

  2. Configure OVF properties

  3. IPv6 Protocol

  4. IPv4 Protocol

Answer: A,B

Question No: 166 – (Topic 4)

An administrator is updating a program running on a virtual machine. The update file has been downloaded as an .iso file and placed on a shared NFS datastore. An attempt to mount the .iso file to the virtual machine fails, but subsequent testing shows that the .iso file can be mounted to a virtual machine running on another ESXi 5.x host.

Which step can be taken to enable access to the .iso file for the affected virtual machine?

  1. Reboot all ESXi hosts in the cluster where the affected virtual machine is running.

  2. Refresh all datastores on the ESXi host running the affected VM.

  3. Rescan all datastores on the ESXi host running the affected VM.

  4. Unmount the volume from the ESXi host running the affected VM, and then add as a new datastore.

Answer: B Explanation:

The first step is to refresh all datastores on the ESXi host running the affected Virtual Machine. This way, the .iso file can be get access from the affected VM. Refreshing datastores, reinitiate the connections and make sure they are working fine.

Question No: 167 – (Topic 4)

During peak operating hours, an administrator finds that a business-critical application running in a virtual machine is not performing as well as during normal hours.

Which memory management method can be used to guarantee that the application performs well at all times?

  1. Set a reservation equal to the average memory utilization of the virtual machine running the application.

  2. Set the share level to high for the virtual machine running the application and set the share level for all other virtual machines to low.

  3. Check the Reserve all guest memory checkbox.

  4. Set a reservation equal to the installed memory of the ESXi host running the application.

Answer: C

Question No: 168 – (Topic 4)

A database administrator has reported periodic poor performance on a particular virtual machine. The virtual machine administrator has noticed a significant drop in performance when utilized memory exceeds 1GB.

What does this indicate and what could be checked next?

  1. The application problems are definitely due to a non-memory-related problem. CPU affinity settings should be checked for this virtual machine.

  2. The application problems are definitely due to a non-memory-related problem. CPU utilization should be checked next, using Windows Task Manager.

  3. The virtual machine might not have physical memory available. Compression and swap activity on the ESXi host should be checked next.

  4. The virtual machine might not have physical memory available. Ensure the memory limit on the VM is set to 0 MB.

Answer: C Explanation:

If the performance degrades when the memory exceeds the allocated value, the virtual machine might not have physical memory available. Check compression and swap activity on ESXi host to see where the additional memory is going.

Question No: 169 – (Topic 4)

What are possible valid uses for the default No Access role in vCenter? (Choose two.)

  1. Restrict usage on a object for a member of a group assigned full permissions to the object

  2. Restrict access to sensitive VMs for helpdesk staff

  3. Restrict ESX Admins from managing specific hosts directly

  4. Restrict administrators from managing hosts via vCenter

Answer: A,D

Question No: 170 – (Topic 4)

Which memory conservation technique collaborates with the server to reclaim pages that are redundant in a virtual machine or virtual machines?

  1. Memory Balloon Driver

  2. Transparent Page Sharing

  3. Redundant Memory Driver

  4. VMkernel Swap
