VMware VMware Certifications VCP5-DCV Questions & Answers

• Question 431:

  How can you verify vStorage APIs for Array Integration (VAAI) is enabled?

  A. "VAAI" listed on the Hard Disk properties page for any VMDK stored on a compliant array

  B. "Hardware Acceleration" listed on the Hard Disk properties page for any VMDK stored on a compliant array

  C. "VAAI" column for any datastore created on a compliant array

  D. "Hardware Acceleration" column for any datastore created on a compliant array

  Correct Answer: D

  If you go to Host > Configuration > Storage, you can see the Hardware Acceleration Status in the panel on the right side.

  For each storage device and datastore, the vSphere Client displays the hardware acceleration support status in the Hardware Acceleration column of the Devices view and the Datastores view.

• Question 432:

  A database administrator has requested that a virtual disk attached to a virtual machine running an I/O intensive database application be fully provisioned. The virtual disk was initially thin provisioned. Which two methods would accomplish this task? (Choose two.)

  A. Use Storage vMotion and change the disk type to Flat.

  B. Use the Inflate option in the Datastore Properties.

  C. Use Storage vMotion and change the disk type to Thick Provisioned Lazy Zeroed.

  D. Use Storage vMotion and change the disk type to Thick Provisioned Eager Zeroed.

  Correct Answer: BD

• Question 433:

  Which two solutions require Raw Device Mapping using virtual compatibility mode? (Choose two.)

  A. Array-based snapshots

  B. virtual machine snapshots

  C. Move the data using Storage vMotion

  D. SAN management agents

  Correct Answer: BC

• Question 434:

  A database administrator has requested a disk for a virtual machine that will run an I/O intensive database application on an ESXi 5.x host. Which two disk types will best fit the needs of the application? (Choose two.)

  A. Raw Device Mapped Disk

  B. Thin Provisioned Disk

  C. Thick Provision Lazy Zeroed Disk

  D. Thick Provision Eager Zeroed Disk

  Correct Answer: AD

  page 31, clearly states that best http://www.vmware.com/pdf/Perf_Best_Practices_vSphere5.0.pdf performance is achieved using eager zeroed provisioned disks, even when VAAI is available

• Question 435:

  Which virtual disk types are supported on an network attached storage appliance using NFS with hardware acceleration disabled?

  A. Flat disk

  B. Raw Device Mappings

  C. Thick Provision Lazy Zeroed

  D. Thin Provision

  Correct Answer: D

  Thin provisioned disk are supported on NAS storage appliance using NFS with disabled hardware acceleration.

• Question 436:

  What are two consequences of deleting a VMFS datastore from an ESXi 5.x host? (Choose two.)

  A. The datastore is inaccessible from all connected ESXi hosts.

  B. The datastore and all virtual machines are removed from the storage device.

  C. The datastore and all virtual machines remain on the storage device.

  D. The datastore is only removed from that specific ESXi host.

  Correct Answer: AB

  The datastore will become inaccessible from all connected ESXi hosts. All the contents including datastore and all virtual machines will be removed from the storage device as well.

• Question 437:

  Click the Exhibit button.

  

  Based on the exhibit, what is the reason that two of the paths are marked as Stand by?

  A. The other two paths were set to Active.

  B. The path configuration is required by the attached storage array.

  C. The active paths were set to Preferred.

  D. The storage adapters need to be rescanned before the paths will be set to Active.

  Correct Answer: B

  The paths are standby because path configuration is required by the attached storage array.

• Question 438:

  When planning for an upgrade from vSphere4 to vSphere5 what will be the effect of upgrading a 1TB VMFS3 datastore with a 2MB block size to VMFS5?

  A. Thick virtual disks can be expanded to a maximum of 2TB.

  B. Thick virtual disks can be expanded to a maximum of 512GB.

  C. Thin virtual disks can be expanded to a maximum of 512GB.

  D. Thin virtual disks can be expanded to a maximum of 2TB.

  Correct Answer: D

• Question 439:

  Click the Exhibit button.

  

  Based on the exhibit, what is the appropriate action to set a preferred path?

  A. Paths cannot be set to preferred on this array.

  B. Right-click the path you want to prefer and then select Preferred.

  C. Right-click the path you want to prefer then select Active.

  D. Double-click the new path you wish to prefer. The other existing paths will be set to Standby.

  Correct Answer: A

  B. You can mount up to 256 NFS datastores

  C. You can use VMware Storage APIs with all NFS datastores

  D. You can use Storage vMotion from a virtual-mode RDM

  Correct Answer: AB
