VMware VMware Certifications VCP5-DCV Questions & Answers

• Question 451:

  When a virtual machine interacts with persistent thick virtual disks stored on a traditional Fibre Channel storage array, which two actions are always taken by the VMkernel? (Choose two.)

  A. The file corresponding to the virtual machine is located on the VMFS datastore using NPIV.

  B. Correlate the blocks requested by the virtual machine with the actual blocks on the array.

  C. Send the I/O request through the device driver to the physical HBA or software FCoE adapter.

  D. Place an atomic lock on the metadata database for the VMFS volume.

  Correct Answer: BC

• Question 452:

  Which two storage adapters require no VMkernel ports? (Choose two.)

  A. Independent Hardware iSCSI Adapter

  B. iSCSI Software Adapter

  C. Dependent iSCSI Adapter

  D. Fibre Channel HBA

  Correct Answer: AD

  Independent hardware iSCSI adapter and Fibre Channel HBA don't need VMkernel ports. Independent hardware iSCSI adapter implements its own networking and management interfaces. All configuration such as IP management, MAC addressing and other parameters are completely separate from VMware.

• Question 453:

  An administrator plans to deploy ESXi 5.x on a blade server containing no local disks. What boot options are supported for use in place of local disks? (Choose three.)

  A. An SD card

  B. A NIC with iBFT

  C. Auto Deploy

  D. A server with IPMI or iLO

  E. A dedicated NFS share

  Correct Answer: ABC

• Question 454:

  When comparing software iSCSI initiators with independent hardware initiators, what are the additional CHAP security levels available for a software implementation? (Choose two.)

  A. Do not use CHAP unless required by target

  B. Use CHAP

  C. Use CHAP unless prohibited by target

  D. Do not use CHAP

  Correct Answer: AB

• Question 455:

  The storage administrator is preparing an action plan to upgrade a Fibre Channel storage array.

  The current plan will result in extended downtime for a VMFS LUN that is part of a SDRS cluster.

  What steps can be taken in a vSphere 5.x environment to minimize the impact of the downtime? (Choose two.)

  A. Ensure there are multiple active paths to the LUN

  B. Ensure DRS is configured properly

  C. Use Storage vMotion to migrate the affected VMDKs

  D. Place the datastore into maintenance mode

  Correct Answer: CD

• Question 456:

  Which two types of information can be obtained about a VMFS datastore using the Summary tab for a connected host in the vSphere Client? (Choose two.)

  A. Multipathing status for the datastore

  B. Hardware Acceleration status

  C. Alarm Actions status for the datastore

  D. Runtime name of the datastore

  Correct Answer: BC

• Question 457:

  An administrator is configuring an ESXi 5.x host with two dual-port Fibre Channel (FC) HBAs. The FC storage array has four active storage processor ports. Zoning is configured on both fabrics, with ESXi HBA ports and the array ports in the same zone. There are two LUNs with VMFS datastores configured.

  Using Round Robin multipathing, what is the maximum number of paths that can be used to send data to the VMFS datastores at any given time?

  A. 2

  B. 3

  C. 1

  D. 4

  Correct Answer: A

  Multi-pathing is set on the HBA level and there are 2 HBAs. Therefore they will alternate on each HBA.

• Question 458:

  Which three features can be used in combination with network-attached storage (NAS)? (Choose three.)

  A. Datastores up to 64TB

  B. virtual-mode RDMs

  C. N-Port ID Virtualization

  D. Storage I/O control

  E. VMware Storage DRS

  Correct Answer: ADE

  In vSphere, you can use NAS with datastores up to 64 TB in capacity, storage I/O control and Storage DRS. NAS supports all three of these.

• Question 459:

  Which three files are valid virtual machine files that might be identified when examining a folder that contains a virtual machine template on a VMFS datastore? (Choose three.)

  A. RDM map file (-rdm.vmdk)

  B. BIOS settings file (.bios)

  C. Template file (.vmtx)

  D. Lock file (.lck)

  E. Suspended state file (.vmsn)

  Correct Answer: ACE

  RDM map file, template file and suspended state file are virtual machine files that reside in a folder named after that virtual machine. The template file is related to virtual machines configurations and the suspended state file is related to configuration that suspends virtual machines. RDM is a mapping file in a separate VMFS volume that acts as a proxy for a raw physical storage device. The RDM allows a virtual machine to directly access and use the storage device. The RDM contains metadata for managing and redirecting disk access to the physical device. The file gives you some of the advantages of direct access to a physical device while keeping some advantages of a virtual disk in VMFS. As a result, it merges VMFS manageability with raw device access. RDMs can be described in terms such as mapping a raw device into a datastore, mapping a system LUN, or mapping a disk file to a physical disk volume. All these terms refer to RDMs.

• Question 460:

  Which are the correct parameters to specify when adding an iSCSI target to an ESXi 5.x host using the Static Discovery tab?

  A. iSCSI server ip address, port 902

  B. iSCSI server ip address, port 3260

  C. iSCSI server ip address, port 902, iSCSI target name

  D. iSCSI server ip address, port 3260, iSCSI target name

  Correct Answer: D
