VMware Certified Professional 6 – Data Center Virtualization Delta Beta Exam

Question No: 71 – (Topic 3)

Which two statements are true regarding VMFS3 volumes in ESXi 6.x? (Choose two.)

  1. Creation of VMFS3 volumes is unsupported.

  2. Upgrading VMFS3 volumes to VMFS5 is supported.

  3. Existing VMFS3 volumes are unsupported.

  4. Upgrading VMFS3 volumes to VMFS5 is unsupported.

Answer: A,B Explanation:

While a VMFS-3, which is upgraded to VMFS-5, provides you with most of the capabilities as a newly created VMFS-5, there are some differences. Both upgraded and newly created VMFS-5 support single-extent volumes up to 64TB and both support VMDK sizes of ~2TB, no matter what the VMFS file-block size is. However additional differences, although minor, should be considered when making a decision whether to upgrade to VMFS-5 or create new VMFS-5 volumes.

What will be created upon completion of the steps in this wizard?

  1. 100GB VMFS5 datastore with free space available for expansion

  2. 100GB VMFS5 datastore with free space available for a second datastore

  3. 100GB VMFS3 datastore

  4. 200.01 GB VMFS5 datastore

available for expansion.

Question No: 75 – (Topic 3)

An administrator is configuring virtual machines to use Worldwide Port Names (WWPNs) to access the storage.

Which two conditions are required? (Choose two.)

  1. The switches in the fabric must be N-Port ID Virtualization aware.

  2. The virtual machines must be using passthrough Raw Disk Mapping (RDMp).

  3. The virtual machines must be using Virtual Machine Disk (VMDK).

  4. The switches in the fabric must be Storage I/O Control aware.

Answer: A,B Explanation:

To configure virtual machines to use WWPNs, you have to set N-Port ID virtualization aware setting on the switches in the fabric and you should also make sure that the virtual machines must be using passthrough raw disk mapping.

Question No: 77 – (Topic 3)

Where is a Virtual SAN Fault Domain configured?

  1. VMware Virtual SAN Cluster configuration

  2. VMware High Availability Cluster configuration

  3. Distributed Resource Scheduler configuration

  4. Datacenter Advanced Settings configuration

Answer: A Explanation:

If your Virtual SAN cluster spans across multiple racks or blade server chassis in a data center and you want to make sure that your hosts are protected against rack or chassis failure, you can create fault domains and add one or more hosts to it.

A fault domain consists of one or more Virtual SAN hosts grouped together according to their physical location in the data center. When configured, fault domains enable Virtual SAN to tolerate failures of entire physical rack as well as failures of a single host, capacity device, network link or a network switch dedicated to fault domains. Fault domains cannot be configured for stretched or metro clusters.

The number of failures your cluster can tolerate depends on the number of failures a virtual machine is provisioned to tolerate. For example, when a virtual machine is configured with Number of failures to tolerate=1 and using multiple fault domains, Virtual SAN can tolerate a single failure of any kind and of any component in a fault domain, including the failure of

an entire rack.

When you configure fault domains on a rack and provision a new virtual machine, Virtual SAN ensures that protection objects, such as replicas and witnesses are placed on different fault domains. If, for example, a virtual machine#39;s storage policy is Number of failures to tolerate=n, Virtual SAN requires a minimum of 2*n 1 fault domains in the cluster. When virtual machines are provisioned in a cluster with fault domains using this policy, the copies of the associated virtual machine objects are stored across separate racks.

Question No: 78 – (Topic 3)

Which two considerations should an administrator keep in mind when booting from Software Fiber Channel over Ethernet (FCoE)? (Choose two.)

  1. Software FCoE boot configuration can be changed from within ESXi.

  2. Software FCoE boot firmware cannot export information in FBFT format.

  3. Multipathing is not supported at pre-boot.

  4. Boot LUN cannot be shared with other hosts even on shared storage.

Answer: C,D Explanation:

When you boot the ESXi host from SAN using software FCoE, certain requirements and considerations apply.

->You cannot change software FCoE boot configuration from within ESXi.

->Coredump is not supported on any software FCoE LUNs, including the boot LUN.

->Multipathing is not supported at pre-boot.

->Boot LUN cannot be shared with other hosts even on shared storage.
