VMware 2VB-601 Online Questions & Answers

• Question 61:

  When using vSAN in a two-node direct connect configuration, how do data nodes communicate with the vSAN witness appliance?

  A. The vCenter Server acts as a proxy between data nodes and the vSAN witness.
  B. An alternate VMkernel interface that has connectivity to the vSAN witness must be tagged with a vSAN traffic type of "witness" VM
  C. Two-node direct connect does NOT require connectivity to the vSAN witness appliance.
  D. If the data node management VMkernel interfaces that are tagged for management traffic only have connectivity with the vSAN witness, they will provide communication with the vSAN witness.
  B. An alternate VMkernel interface that has connectivity to the vSAN witness must be tagged with a vSAN traffic type of "witness" VM

  ---

  Traditional vSAN 2 Node configurations require connectivity between the vSAN tagged VMkernel ports, and the vSAN Witness Appliance's VSAN tagged VMkernel port. 2 Node Direct Connect Witness Traffic Separation provides the ability to directly connect vSAN data nodes in a 2 Node configuration. Traffic destined for the Witness host can be tagged on an alternative interface from the directly connected vSAN tagged interface.

• Question 62:

  Which format for desktops does vSAN support?

  A. vmfsSparse
  B. SE Sparse Disk
  C. Horizon Sparse
  D. vSAN Sparse
  D. vSAN Sparse

• Question 63:

  Which are two functions of software checksums in a vSAN environment? (Choose two.)

  A. Limit the number of IOPS that an object can consume
  B. Perform disk scrubbing in the background
  C. Limit the number of reads to the capacity tiered disks
  D. Automatically detect and resolve silent disk errors
  B. Perform disk scrubbing in the background
  D. Automatically detect and resolve silent disk errors

  ---

  Software checksums which will perform the following checks:

  1.

  Write failures to disks

  2.

  Network copy failures

  3.

  Checksum failures ?will fetch data from another copy.

  4.

  Disk Scrubbing will run in the background

  5.

  Enables additional level of data integrity

  6.

  Automatically detects and solve silent disk errors

• Question 64:

  A three-host hybrid vSAN has been deployed. Hardware maintenance is required for one of the hosts. What happens when the host is place into maintenance mode using the "Evacuate all data" option?

  A. All data is migrated from the host that is being placed into maintenance mode. Data redundancy is temporarily reduced.
  B. All data is migrated from the host that is being placed into maintenance mode. Once the data migration is complete, the host enters maintenance mode.
  C. The host enters maintenance mode.. A warning displays indicating it is NOT possible to migrate all data from the host if any object has a policy assigned where Primary level of failures to tolerate is greater than 0.
  D. When working with a three-host cluster, you CANNOT place a server in maintenance mode with the "Evacuate all data" option selected.
  D. When working with a three-host cluster, you CANNOT place a server in maintenance mode with the "Evacuate all data" option selected.

  ---

  A cluster with three fault domains has the same restrictions that a three-host cluster has, such as the inability to use Evacuate all data mode or to reprotect data after a failure.

• Question 65:

  Which three statements are true regarding vSAN networking requirements? (Choose three.)

  A. Each host must have minimum bandwidth dedicated to vSAN: 1. Dedicated 1 Gbps for hybrid configurations. 2. Dedicated or shared 10 Gbps for all-flash configurations.
  B. vSAN supports both IPv4 and IPv6.
  C. Each host in the vSAN cluster must have a VMkernel network adapter with vSAN traffic enabled.
  D. Each host in a vSAN cluster must use NIC teaming with NetFlow enabled.
  E. The vSAN port group must have Promiscuous Mode emabled.
  A. Each host must have minimum bandwidth dedicated to vSAN: 1. Dedicated 1 Gbps for hybrid configurations. 2. Dedicated or shared 10 Gbps for all-flash configurations.
  B. vSAN supports both IPv4 and IPv6.
  C. Each host in the vSAN cluster must have a VMkernel network adapter with vSAN traffic enabled.

• Question 66:

  Which two factors below determine how a VMDK object will be split on a vSAN cluster? (Choose two.)

  A. Checksum parameter
  B. Free capacity in the cache tier devices
  C. Size of the VMDK object
  D. Stripe width parameter
  C. Size of the VMDK object
  D. Stripe width parameter

  ---

  Note: Number Of Disk Stripes Per Object, commonly referred to as stripe width, is the setting that defines the minimum number of capacity devices across which each replica of a storage object is distributed.

• Question 67:

  For a hybrid vSAN configuration, the SSD resides in which tier?

  A. Read tier
  B. Write tier
  C. Cache tier
  D. Capacity tier
  C. Cache tier

  ---

  In a VMware vSAN configuration, the SSDs are used for the vSAN caching layer for hybrid deployments and for the capacity layer for all flash.

• Question 68:

  In order to support Oracle Real Application Cluster (RAC), which change must be made to each applicable virtual machine?

  A. Set virtual disk sharing to multiwrite mode.
  B. Enable vApp options.
  C. Change SCSI controller type from virtual to physical.
  D. Enable virtual machine Memory Hot Plug.
  A. Set virtual disk sharing to multiwrite mode.

• Question 69:

  An administrator has configured a storage policy with a Primary level of failures to tolerate set to 3 and assigned this policy to a virtual disk.

  What is the minimum number of hosts required in this vSAN cluster?

  A. 3
  B. 4
  C. 6
  D. 7
  B. 4

• Question 70:

  vSAN storage policies can be created from which three of the listed vSAN rules? (Choose three.)

  A. Compression/Deduplication enabled/disabled
  B. Disable object checksum
  C. Primary level of failures to tolerate
  D. Replication enabled/disabled
  E. Force provisioning
  B. Disable object checksum
  C. Primary level of failures to tolerate
  E. Force provisioning

  B: Checksum vSAN 6.2 includes End-to-End Software checksum to help avoid data integrity issues that may arise in the underlying disks. By default, checksum is enabled in version 6.2 but can be explicitly disabled via a storage policy setting. Software checksum can be disabled by completing the following procedure.

  1.

  From the vSphere Web Client, click Policies and Profiles and Select VM Storage Policies.

  2.

  Select a Virtual Machine Policy.

  3.

  Right click and Select "Edit Settings"

  4.

  From the Rule-Set 1 screen, select "Add rule"

  5.

  Select "Disable object checksum" from the drop down list
