• Question 443:

  A virtual machine requires a 4TB disk for application data. The storage administrator has already created and presented a 4TB LUN to an ESXi 5.x host. The host is currently configured with a single 500GB VMFS5 datastore. What is the next step the vSphere administrator must use to provision the data disk?

  A. Create a virtual compatibility mode RDM mapping to the 4TB LUN.

  B. Create a physical compatibility mode RDM mapping to the 4TB LUN.

  C. Expand the existing VMFS volume to 4TB. Create a physical compatibility mode RDM mapping to the 4TB LUN.

  D. Expand the existing VMFS volume to 4TB. Create a virtual compatibility mode RDM mapping to the 4TB LUN.

  Correct Answer: B

• Question 444:

  Where must the VMware vSphere Storage Appliance Manager (VSA Manager) be installed?

  A. On a Windows virtual machine created on the first VSA host

  B. The VSA Manager is deployed as a separate virtual appliance

  C. On a vCenter Server outside of the VSA environment

  D. It is pre-installed on the VMware vSphere Storage Appliance

  Correct Answer: C

  VMware vsphere storage appliance manager is always installed on a vcenter server that resides outside of VSA environment.

• Question 445:

  What are two requirements when configuring a Fibre Channel SAN with an ESXi 5.x cluster? (Choose two.)

  A. RDMs must be zoned and masked to each ESXi 5 host in the cluster

  B. A FCP HBA or hardware supporting FCoE must be installed in the hosts

  C. Each LUN should contain only one NFS datastore.

  D. Each LUN must present a unique LUN ID to each ESXi hosts.

  Correct Answer: AB

  A: correct because yes, you have to Zone and mask to allow only the Hosts in that you want in.

  Zoning has the following effects:

  -Reduces the number of targets and LUNs presented to a host.

  -Controls and isolates paths in a fabric.

  -

  Can prevent non-ESXi systems from accessing a particular storage system, and from possibly destroying VMFS data.

  -

  Can be used to separate different environments, for example, a test from a production environment.

  B: correct because yes you need HBAs to connect to the FC.

  C is obviously wrong as the FS is VMFS not NFS

  D is wrong because: Page 37 of the vSphere storage guide says. For multipathing to work properly, each LUN must present the "same" LUN ID number to all ESXi hosts.

• Question 446:

  What two statements are true about Fibre Channel zoning? (Choose two.)

  A. Zones define paths to a Fibre Channel array

  B. Zones control access to LUNs on a Fibre Channel storage array

  C. Zones can be soft or hard

  D. Zones can be configured on an array or ESXi host

  Correct Answer: AC

• Question 447:

  How does a hardware FCoE Adapter appear to an ESXi host?

  A. As an uplink adapter attached to a vSphere Distributed Switch.

  B. As a hardware FCoE Adapter.

  C. As an enabled FCoE software initiator.

  D. As a Fibre Channel Adapter.

  Correct Answer: D

• Question 448:

  A vSphere 5.x environment has an ESXi 5.x host configured to boot from a hardware independent iSCSI adapter. What is the expected outcome if the administrator attempts to disable the iSCSI HBA in the vSphere client?

  A. The adapter will be disabled, but is re-enabled the next time the host boots up.

  B. The adapter will be disabled and the host will not boot the next time the host boots up.

  C. A hardware independent iSCSI adapter cannot be disabled from the vSphere Client.

  D. The adapter will be enabled, but the host will boot into troubleshooting mode the next time the host boots up.

  Correct Answer: C

• Question 449:

  ACME Tools has a vSphere 5.x deployment with an older iSCSI storage array. The administrator is considering adding an additional array, which will include support for the vStorage APIs for Array Integration (VAAI). Which two tasks would be completed in a reduced period of time if the new array was added? (Choose two.)

  A. creating VMFS datastores on the new array

  B. creating fault tolerant virtual machines on the new array

  C. migrating virtual machines using Storage vMotion between the arrays

  D. writes to thin provisioned virtual disks on the new array

  Correct Answer: BD

• Question 450:

  Which options would reduce the load on the VMkernel when connecting to an iSCSI array? (Choose two.)

  A. Use an independent hardware iSCSI adapter

  B. Use a Converged Network Adapter

  C. Enable the software iSCSI adapter

  D. Use a dependent hardware iSCSI adapter

  Correct Answer: AD

  Since independent hardware iSCSI adapter doesn't need a VMkernel port, and it uses all its networking and management interfaces all by itself, it will significantly reduce the load on VMkernel. Similarly, dependent iSCSI adapter use very little resources and hence can reduce the load off VMkernel.
