VMware VMware Certifications VCP5-DCV Questions & Answers

• Question 401:

  An administrator is creating a virtual machine that will be running Windows 2008 Enterprise (64-bit). The application to be installed in the virtual machine requires eight vCPUs to run effectively. During installation, the only available options are one, two, three, or four vCPUs.

  What condition explains the available vCPU selections?

  A. The virtual machine hardware version is 8.

  B. The guest operating system for the virtual machine is 64-bit.

  C. The ESXi host has two non hyperthreaded dual-core CPUs.

  D. The ESXi host has two hyperthreaded dual-core CPUs.

  Correct Answer: C

• Question 402:

  Click the Exhibit button.

  

  Which statement is true about the network performance of the virtual machine in the exhibit?

  A. The virtual machine can send at the maximum of 10Mbps.

  B. The virtual machine can send traffic as fast as the underlying virtual switch allows.

  C. Virtual switch autonegotiation settings must to be adjusted to improve performance.

  D. The underlying physical NIC is configured for 10Mbps.

  Correct Answer: B

  Explanation,

  The virtual machine sends traffic as fast as the underlying virtual switch allows.

• Question 403:

  An administrator is deploying several ESXi 5.x hosts. Centralized logging with accurate timestamps is a requirement for the deployment. Which two operations ensure these requirements are met? (Choose two.)

  A. Ensure TCP port 123 is not blocked

  B. Configure a syslog server on each host

  C. Configure ensure the hosts have the proper timezone configured

  D. Configure a syslog server on the vSphere Management Appliance

  Correct Answer: AD

  For centralized logging with accurate timestamps, you need to make sure TCP port 123 is not blocked. You also need to configure a syslog server on the VSA.

• Question 404:

  An administrator attempts to increase the number of vCPUs in a virtual machine to 8. The configuration cannot be successfully completed. What are two likely causes of this issue? (Choose two.)

  A. MS-DOS was selected as guest OS.

  B. The host has 4 processor threads.

  C. Virtual machine hardware version 7 was chosen.

  D. The vSphere 5.x implementation is using a Standard license.

  Correct Answer: AB

  The reasons that can cause the configuration of vCPUs in a VM to not get successfully completed can be several. First, if you have selected MS DOS as a guest OS, then it would not support 8 vCPUs. Check the processor threads. If it has 4 ot less than 4 threads, you cannot increase the number of vCPUs in a VM.

• Question 405:

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

  A. Memory Balloon Driver

  B. Transparent Page Sharing

  C. Redundant Memory Driver

  D. VMkernel Swap

  Correct Answer: B

• Question 406:

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

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

  B. Restrict access to sensitive VMs for helpdesk staff

  C. Restrict ESX Admins from managing specific hosts directly

  D. Restrict administrators from managing hosts via vCenter

  Correct Answer: AD

• Question 407:

  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?

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

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

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

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

  Correct Answer: C

  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 408:

  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?

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

  B. 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.

  C. Check the Reserve all guest memory checkbox.

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

  Correct Answer: C

• Question 409:

  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?

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

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

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

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

  Correct Answer: A

• Question 410:

  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.)

  A. Transient IP Addresses

  B. Configure OVF properties

  C. IPv6 Protocol

  D. IPv4 Protocol

  Correct Answer: AB
