VMware VMware Certifications VCP5-DCV Questions & Answers

• Question 461:

  An administrator decides to implement a Fixed multipathing policy for an ESXi 5.x host with four available paths to one VMFS datastore. After the policy has been enabled for the datastore, how many paths will have an active status by default?

  A. 4

  B. 3

  C. 1

  D. 2

  Correct Answer: A

  When the policy has been enabled for the datastore, 4 paths will have active status by default.

• Question 462:

  Click the Exhibit button.

  

  What does the graph in the exhibit indicate?

  A. The average amount of read and write latency from the ESXi host to the SAN.

  B. The average amount of read and write latency from the guest operating system to the virtual machine virtual disk file.

  C. The average amount of read and write latency from the ESXi host to the datastore.

  D. The average amount of read and write latency from the cluster to the datastore.

  Correct Answer: C

• Question 463:

  A request has been made to the SAN administrator to provision a new LUN. A LUN (LUN 6) is created, and the SAN administrator presents the LUN to an ESXi 5.x host, using the storage array SAN management software. The administrator looks at the Storage configuration for the ESXi host, and does not see the new LUN. Other LUNs from the same storage array are visible. Which two conditions are most likely to cause the error described? (Choose two.)

  A. The administrator has not performed a Rescan All on the ESXi host.

  B. The multipathing policy has been set to Fixed for the LUN.

  C. Zoning on the Fibre Channel switches is not configured correctly.

  D. The LUN was not presented to the correct ESXi host.

  Correct Answer: AD

  The cause of the error is that the administrator didn't perform a rescan all of ESXi host. Whenever a new LUN is provisioned, a manual rescan all has to be performed to enable ESXi to discover new LUNs. The second possibility is that the new LUN was not presented to the ESXi host that was intended by the administrator.

• Question 464:

  When designing a storage infrastructure to support ESXi 5.x hosts what limit will be reached first?

  A. Maximum number of NFS datastores

  B. Maximum number of iSCSI LUNs

  C. Maximum number of paths to an iSCSI RDM

  D. Maximum number of iSCSI paths on a host

  Correct Answer: C

  When the storage infrastructure is designed to support ESXi 5 hosts, the number of path to an iSCSI RDM are reaches its limit first.

• Question 465:

  Which is the most secure method of connecting to an iSCSI storage array using an independent hardware iSCSI adapter?

  A. One-way CHAP

  B. Mutual CHAP

  C. Per-target CHAP

  D. Per-subnet CHAP

  Correct Answer: A

  If you're thinking two direction CHAP authentication would be the most secure, you would probably be right EXCEPT the question was about an independent hardware iSCSI adapter. As per the VMware pubs page: "Independent hardware iSCSI supports CHAP only at the initiator level." which means One-way CHAP.

• Question 466:

  What is the default VFAT scratch partition size for ESXi 5.x when installed on a USB drive?

  A. 600MB

  B. 544MB

  C. 4GB

  D. none

  Correct Answer: D

• Question 467:

  What is one requirement when adding an extent to a VMFS datastore?

  A. A new unused NFS mount

  B. An RDM with sufficient space available

  C. An unused iSCSI or FCP LUN

  D. Free space on the LUN holding the VMFS datastore

  Correct Answer: C

• Question 468:

  How can you verify that vStorage APIs for Array Integration (VAAI) functionality is enabled for a storage array in a vSphere 5.x implementation?

  A. VAAI will be reported on the Hard Disk properties page for any VMDK stored on a compliant array

  B. Hardware Acceleration will be reported on the Hard Disk properties page for any VMDK stored on a compliant array

  C. Supported will be listed in the VAAI column for any datastore created on a compliant array

  D. Supported will be listed in the Hardware Acceleration column for any datastore created on a compliant array

  Correct Answer: D

• Question 469:

  Click the Exhibit button.

  

  For the selected item, what two properties could the storage administrator use to create a zone? (Choose two.)

  A. 20.00.00.1b.32.13.14.a7

  B. vmhba1.C0.T0.L1

  C. fc.2000001b321314a7.2100001b321314a7

  D. 50.06.01.60.c1.e0.65.22

  Correct Answer: AD

  Fibre channel adapter and target needs to be used to create a zone.

• Question 470:

  A new LUN has been provisioned to all hosts in a vSphere 5.x cluster. On one host a new VMFS datastore has been created. How will the new datastore be discovered by the other ESXi 5.x hosts?

  A. A rescan of all host bus adapters is periodically performed by ESXi hosts to detect new VMFS datastores.

  B. New VMFS volumes are automatically added to members of a cluster by vCenter 5.

  C. A manual refresh is required on each ESXi 5.x hosts to discover new VMFS datastores.

  D. A refresh of all host bus adapters is periodically performed by ESXi hosts to detect new VMFS datastores.

  Correct Answer: C

  You need to manually refresh every ESXi 5.x host to get it to discover newly added VMFS datastores.
