VMware VMware Certifications VCP-510 Questions & Answers

• Question 371:

  Click the Exhibit button. An administrator is configuring vMotion in their environment. As part of the implementation, an administrator is examining resource mapping for virtual machines. What is a likely cause of the error shown in the exhibit?

  

  A. vMotion has been disabled because the are no other hosts in the cluster with vMotion enabled.

  B. vMotion has not been enabled on the Production port group.

  C. The administrator has not created a Managent network.

  D. vMotion has not been enabled on a VMkernel port group.

  Correct Answer: D

• Question 372:

  Which of these factors indicates a high likelihood that the performance of a virtual machine disk is being constrained by disk I/O?

  A. A large number of commands issued

  B. A high device latency value

  C. A high disk used value

  D. A large number of kilobytes read and written

  Correct Answer: B

• Question 373:

  An administrator has determined that storage performance to a group of virtual machines is reduced during peak activity.

  The virtual machines are located in a VMFS datastore called Production1 on an active-active storage array.

  The ESXi 5.x host running the virtual machines is configured with an MRU multipathing policy. Which two actions can be taken to improve the storage performance of these virtual machines? (Choose two.)

  A. Add virtual storage, create a VMFS datastore called Production2 on the new storage, and then migrate some of the virtual machines from Production1 to Production2.

  B. Change the storage multipathing policy to Round Robin.

  C. Add physical storage, create a VMFS datastore called Production2 on the new storage, and then migrate some of the virtual machines from Production1 to Production2.

  D. Change the storage multipathing policy to Fixed with default settings.

  Correct Answer: BC

• Question 374:

  A company wants to increase disk capacity for their vSphere environment Management mandates that:

  1.

  vMotion must work in this environment.

  2.

  The existing LAN infrastructure must be used.

  Which storage option best meets the company objectives?

  A. iSCSI

  B. Fibre Channel

  C. SATA

  D. NFS

  Correct Answer: D

• Question 375:

  Which resource management technique can be used to relieve a network bottleneck caused by a virtual machine with occasional high outbound network activity?

  A. Convert the switch from a vSphere Standard Switch to a vSphere Distributed Switch.

  B. Create a new port group for the virtual machine and enable traffic shaping.

  C. Apply traffic shaping to the other virtual machines in the same port group.

  D. Apply traffic shaping to the virtual machine with high activity.

  Correct Answer: B

• Question 376:

  An administrator is informed that there will be a storage maintenance window and that failovers may occur. What is the expected length of time that a Windows 2008 virtual machine storage I/O will pause during a path failover?

  A. 0 to 30 seconds

  B. 90 to 120 seconds

  C. 60 to 90 seconds

  D. 30 to 60 seconds

  Correct Answer: D

• Question 377:

  An administrator receives a complaint that a virtual machine is performing poorly. The user attributes the issue to poor storage performance. If the storage array is the bottleneck, which two counters would be higher than normal? (Choose two.)

  A. Average ESXi VMKernel latency per command, in milliseconds (KAVG per cmd)

  B. Average device latency per command, in milliseconds (DAVG per cmd)

  C. Average virtual machine operating system latency per command, in milliseconds (GAVG per cmd)

  D. Number of SCSI reservation conflicts per second (CONS per second)

  Correct Answer: BD

• Question 378:

  An administrator must decommission a datastore. Before unmounting the datastore, which three requirements must be fullfilled? (Choose three.)

  A. No virtual machines reside on the datastore.

  B. The datastore is not used for vSphere HA heartbeat.

  C. No registered virtual machines reside on the datastore.

  D. The datastore must not have any extents.

  E. The datastore must not be part of a datastore cluster.

  Correct Answer: ABE

• Question 379:

  An administrator is unable to connect a vSphere Client to an ESXi 5.x host. Which option can be selected from the direct console to restore connectivity without disrupting running virtual machines?

  A. Restore the Standard Switch from the ESXi host.

  B. Restart the Management Agents from the vSphere client.

  C. Restart the Management Agents from the ESXi host

  D. Disable the Management Network from the vSphere client.

  Correct Answer: C

• Question 380:

  A user attempts a remote SSH connection to a newly-installed ESXi 5.x host to execute some commands. The SSH connection attempt fails, though the user is able to receive a ICMP ping back from the host. What must the administrator do to enable SSH? (Choose two.)

  A. Enable root logon on the ESXi server.

  B. Open the SSH port on the ESXi firewall.

  C. Start the SSH service on the ESXi server.

  D. Create a local user on the ESXi server.

  Correct Answer: BC
