An administrator is tasked with setting up HCI mesh between the following two vSAN clusters:

• Cluster 1 uses FTT=1 via mirroring
• Cluster 2 uses FTT=1 via Erasure Coding

The administrator configures Cluster 2 as the cluster that is contributing storage to HCI mesh.

Which FTT applies to objects created on Cluster 1 when using the HCI Mesh shared storage?

  • A. HCI mesh always uses FTT = 1.
  • B. HCI Mesh always uses the default vSAN policy from the target site.
  • C. HCI Mesh always uses the source vSAN cluster to set its policy.
  • D. HCI mesh always uses FTT = 0.


Answer : B

Due to an update in their security requirements, an organization is no longer compliant because the metadata traffic between hosts in their vSAN cluster is not being encrypted.

Which step must be taken by the administrator to meet the new security requirements?

  • A. Enable vMotion encryption on the vSAN cluster.
  • B. Enable virtual machine encryption on the vSAN cluster.
  • C. Enable Data-At-Rest Encryption on the vSAN cluster.
  • D. Enable Data-In-Transit Encryption on the vSAN cluster.


Answer : D

A vSAN administrator notices that all the applications on a vSAN cluster are suffering from performance degradation. The main applications on this cluster are very random write-intensive and generate a lot of i/o. De-staging seems to be going awfully slow.

Given the following information:

• Each host has a single disk group.
• Each disk group has 7 capacity disks.
• The size of each cache disk is 600 GB.

How should the administrator solve this problem?

  • A. Add additional disk groups
  • B. Add more capacity disks
  • C. Add more cache disks
  • D. Increase the size of cache disks


Answer : D

An organization has two vSAN clusters managed by the same vCenter server, each providing 100 TB of storage. The first cluster runs at 75% of its storage capacity, and the second cluster runs at 40% of its storage capacity.

The company also has the following:

• an iSCSI array of 300 TB, which runs at 76% of its capacity
• a NAS system of 200 TB, which runs at 10% of its capacity
• a Fiber channel (FC) array of 300 TB, which runs at 80% of its capacity

The administrator is asked to add an additional 25 TB of storage to the first cluster but is also made aware that there is no budget to purchase new hardware and that the vSAN Storage Policy Based Management must be kept in place.

Which storage option will work for this use case?

  • A. Use the iSCSI array to obtain additional free capacity.
  • B. Use the NAS to obtain additional free capacity.
  • C. Use an HCI Mesh to obtain additional capacity.
  • D. Use the FC array to obtain additional free capacity.


Answer : C

A capacity upgrade to a production vSAN 7.0 U1 cluster will provide an administrator with a number of SSD storage devices that can be reused in the development vSAN Cluster.

The company security policy mandates the following:

• All data must be encrypted-at-rest.
• All data on all drives must be securely erased before being removed and reused.

Which two steps should the administrator take to ensure that all data on the storage devices is securely erased? (Choose two.)

  • A. When putting the node in maintenance mode, choose the Ensure data accessibility option.
  • B. Run the Start-VsanWipeDisk PowerCLI command.
  • C. Turn off vSAN Encryption on the vSAN Cluster.
  • D. When putting the nodes in maintenance mode, choose the Evacuate all data option.
  • E. When putting the node in maintenance mode, choose the No data evacuation option.


Answer : BD

A faulty disk was not cleanly removed from the vSAN cluster when being replaced.

Which action should be taken to resolve the problem and restore the vSAN cluster to a healthy state?

  • A. Delete and recreate the disk group.
  • B. Reboot the host to clear the lock.
  • C. Rescan the SCSI adapter to clear the lock.
  • D. Ignore the errors, and add the new disk into the disk group.


Answer : A

An administrator is discussing the "No Data Migration" vSAN maintenance mode.

In which situation should the administrator recommend this mode?

  • A. When the VMs are protected by vSphere Fault Tolerance
  • B. When the vSAN host requiring maintenance is a compute node only
  • C. When the cluster has three fault domains configured
  • D. When objects are configured with FTT=0


Answer : D

An administrator notes that the Data-At-Rest Encryption keys have expired.

Which action is needed to resolve this situation?

  • A. Add a new Standard Key Provider at the vSAN cluster level
  • B. Generate new encryptions keys at the vSAN cluster level
  • C. Add an additional KMS at the vCenter server level
  • D. Generate new encryptions keys at the vCenter server level


Answer : B

An administrator has changed the Virtual Machine Storage Policy from RAID-5 to RAID-6.

How many failures can be tolerated when this change is made?

  • A. 3
  • B. 4
  • C. 2
  • D. 5


Answer : C

An administrator is troubleshooting vSAN performance issues, and the performance diagnostics reports:

"There are errors seen in one or more physical NICs on one or more hosts."

Which two problems must be resolved to fix this issue? (Choose two.)

  • A. A 25 Gb/s NIC needs to be installed.
  • B. There are incompatible firmware and driver versions.
  • C. There is an incorrectly set MTU.
  • D. The vSAN version needs to be upgraded to 7.0.
  • E. A firewall is blocking ports.


Answer : BC

During a vSAN design workshop, the customer has provided the following information:

• There are many development activities that require burst compute and that there is an in-tention to use the existing ESXi hosts.
• The existing ESXi hosts are not vSAN ready nodes, so they will not be participating in vSAN capacity.

Which three recommendations should the architect make? (Choose three.)

  • A. Compute-only hosts can have a vSAN VMkernel with same pNIC speed.
  • B. It is recommended to add hosts with at least a disk controller for cluster expansion.
  • C. Compute-only hosts can consume from vSAN even if not within the same cluster.
  • D. Adding identical vSAN nodes for cluster expansion will support an efficient operation.
  • E. Compute-only hosts must exist in the same vSAN cluster.
  • F. Compute-only hosts must have a vSAN VMkernel with same pNIC speed.


Answer : ADE

During a vSAN design workshop, the customer expressed the following requirements:

• The ESXi hosts will have their disk related hardware changed to become vSAN nodes.
• The default storage policy will be based on an FTT=2 (Failures to Tolerate).
• The vSAN Primary level of failures to tolerate (PFTT) will be set to a value of 2.

Based on the request, the architect was shown the following information about the current cluster:

• The number of existing ESXi hosts is 8.
• vSphere High Availability (HA) Admission control set to 37.5%.

How does this information impact the vSAN cluster design?

  • A. Secondary level of failures to tolerate must be defined with a value of 2.
  • B. The current configuration is recommended for the vSAN transformation.
  • C. The vSphere HA Admission Control must be set to a maximum of 25%.
  • D. Proactive HA should be enabled on the vSAN cluster.


Answer : C

A vSAN policy has been configured with Erasure Coding on a vSAN stretched cluster.

Which RAID level and FTT setting have been specified?

  • B. PFTT with RAID1
  • C. PFTT with RAID5/6
  • D. SFTT with RAID5/6
