What are two methods of maximizing VMFS performance for virtual machines across all the hosts in a cluster? (Choose two.)

  1. Use disk shares to prioritize virtual machine disk I/O

  2. Enable Storage I/O control

  3. Enable Storage DRS with I/O load balancing

  4. Enable Host Cache using local SSD drives

Answer: B,C Explanation:

To maximize VMFS performance of virtual machines, you can enable Storage I/O control and storage DRS with I/O load balancing.

Answer: A,D Explanation:

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

Question No: 104 – (Topic 3)

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?

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

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

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

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

Answer: C Explanation:

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

Question No: 105 – (Topic 3)

The storage administrator has recommended testing the performance benefits of jumbo frames and enabled jumbo frames on the storage array. The VMware administrator has enabled jumbo frames on the VMkernel port used for the software iSCSI initiator.

What other two components must be modified to enable jumbo frames support for the software iSCSI initiator? (Choose two.)

  1. The physical switch

  2. The port group

  3. The software initiator

  4. The virtual switch

Answer: A,D

Question No: 106 – (Topic 3)

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

  1. 600MB

  2. 544MB

  3. 4GB

  4. none

Answer: D

Question No: 107 – (Topic 3)

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

  1. A new unused NFS mount

  2. An RDM with sufficient space available

  3. An unused iSCSI or FCP LUN

  4. Free space on the LUN holding the VMFS datastore

Answer: C

Question No: 108 – (Topic 3)

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

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

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

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

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

Answer: D

Reference: http://www.vmware.com/files/pdf/techpaper/VMware-vSphere-Storage-API-


Question No: 109 – (Topic 3)

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

  1. Maximum number of NFS datastores

  2. Maximum number of iSCSI LUNs

  3. Maximum number of paths to an iSCSI RDM

  4. Maximum number of iSCSI paths on a host

Answer: C Explanation:

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 No: 110 – (Topic 3)

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

  1. One-way CHAP

  2. Mutual CHAP

  3. Per-target CHAP

  4. Per-subnet CHAP

Answer: A Explanation:

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.
