• Question 23:

  Which vSAN health check category is viewed to confirm supported storage controller drivers are in use across all hosts in the cluster?

  A. Online health
  B. Hardware Compatibility
  C. Physical disk
  D. Cluster
  B. Hardware Compatibility

  ---

  vSAN Health Service - Hardware Compatibility - Controller Firmware Check

  This health check verifies whether the storage I/O controller firmware is compatible with the controller on the ESXi host and the version of ESXi.

  If the controller is on the VMware vSAN Hardware Compatibility List (HCL) and passes appropriate controller checks, the Controller Firmware Check verifies that there the firmware version in use is on the list of supported drivers.

• Question 24:

  In a vSAN stretched cluster with Primary level to tolerate set to 1 and Secondary level of failure to tolerate set to 2, what is the maximum amount of space that a 100GB virtual disk could consume without any other policy rules set?

  A. 200GB
  B. 100GB
  C. 400GB
  D. 600GB
  C. 400GB

• Question 25:

  What are IOPS?

  A. The amount of network bandwidth measured in segments that is required to process iSCSI overhead.
  B. The number of input and/or output operations in one second.
  C. Integrated Output Performance Statistic.
  D. Intermittent Operations in Primary Storage.
  B. The number of input and/or output operations in one second.

  ---

  Input/output operations per second (IOPS, pronounced eye-ops) is an input/output performance measurement used to characterize computer storage devices like hard disk drives (HDD), solid state drives (SSD), and storage area networks (SAN).

• Question 26:

  The following are the configuration details of a 12-node all-flash VSAN cluster:

  1.

  Every node has one disk group

  2.

  Each disk group consists of one cache device and six capacity devices

  Which two methods can be used to increase the size of the cache tier in each host? (Choose two.)

  A. Promote a capacity device to a cache device so that each disk group has two cache devices.
  B. Add a new cache device to the host. Reconfigure the host to have two disk groups with one cache device and three capacity devices per disk group.
  C. Add a second cache device to each disk group.
  D. Replace the existing cache device in each disk group with a larger cache device.
  C. Add a second cache device to each disk group.
  D. Replace the existing cache device in each disk group with a larger cache device.

  ---

  As you create disk groups on each host and add cache and capacity devices, the size of the datastore increases according to the amount of physical capacity added by those devices.

  Typically, you delete devices or disk groups from vSAN when you are upgrading a device or replacing a failed device, or when you must remove a cache device.

• Question 27:

  What are two main advantages of using multiple disk groups within each host? (Choose two.)

  A. Performance
  B. Backward compatibility
  C. Cost
  D. Redundancy
  A. Performance
  D. Redundancy

• Question 28:

  Consider the following vSAN cluster scenario:

  1.

  All hosts are members of the same cluster.

  2.

  All hosts are contributing storage capacity to the vSAN datastore.

  3.

  There is not vSAN Witness Host.

  4.

  All virtual machines are assigned a storage policy where Primary level of failures to tolerate = 1.

  What is the minimum number of physical hosts required to be a supported vSAN configuration?

  A. Five (5)
  B. Three (3)
  C. Two (2)
  D. Four (4)
  B. Three (3)

  VMware vSAN Design and Sizing Guide 6.5. Page: 18 When not using a witness, there is a minimum requirement of 3 ESXi hosts in a vSAN cluster. This is the same for all versions. While vSAN fully supports 3-node configurations, they can behave differently than configurations with 4 or greater nodes. In particular, in the event of a failure there is no way for vSAN to rebuild components on another host in the cluster to tolerate another failure. Also with 3-node configurations, vSAN does not have the ability to migrate all data from a node during maintenance.

• Question 29:

  What are two ways to examine the storage policy compliance of a virtual machine? (Choose two.)

  A. 1. Browse to the virtual machine in the vSphere Web Client navigator. 2. On the Summary tab, examine the value of the VM Storage Policy Compliance property under VM Storage Policies.
  B. 1. Browse to the virtual machine in the vSphere Web Client navigator. 2. Right-click the virtual machine and select "Check storage policy compliance".
  C. 1. In the vSphere Web Client, navigate to the vSAN cluster. 2. On the Storage tab, click vSAN and select Virtual Disks. 3. Right-click on the virtual machine and select "Compliance status".
  D. 1. In the vSphere Web Client, navigate to the vSAN cluster. 2. On the Monitor tab, click vSAN and select Virtual Objects. 3. Select a virtual object. 4. Examine the value in the Compliance Status property for the object.
  A. 1. Browse to the virtual machine in the vSphere Web Client navigator. 2. On the Summary tab, examine the value of the VM Storage Policy Compliance property under VM Storage Policies.
  B. 1. Browse to the virtual machine in the vSphere Web Client navigator. 2. Right-click the virtual machine and select "Check storage policy compliance".
