Which step should be performed to exit the locked state?

A. Manually replace the Host Encryption Key (HEK) of each affected host.

B. Restore the communication with the KMS server, and re-establish the trust relationship.

A. Add the new vSAN witness appliance to vCenter Server.

B. Deploy a new large vSAN witness appliance at the witness site.

C. Configure the vSAN stretched cluster to use the new vSAN witness.

D. Deploy a new extra large vSAN witness appliance at the witness site.

E. Upgrade the vSAN stretched cluster to vSAN 7.0 U1.

An administrator has received an alert indicating that a single capacity device is close to failing within the production vSAN Cluster. The administrator must now complete preemptive maintenance on the vSAN Cluster without impacting the availability of workloads or vSAN File Services.

The following information is known about the vSAN Cluster: vSAN 7.x Cluster vSAN node count: 8 De-Duplication and Compression: Enabled. Encryption: Disabled Current Utilization: 45% Disk Groups: 2 Devices per node: 2 x 400 GB SSD, 6 x 1.8 TB SSD

Which three steps should the administrator take to successfully complete the task? (Choose three.)

A. Remove the affected Disk Group from the vSAN Cluster, and choose Full Data Migration.

B. Replace the failed disk with a storage device that is identical in class and capacity.

C. Remove the affected Disk Group from the vSAN Cluster, and choose No Data Migration.

D. Replace the failed disk with a storage device that is identical in class but smaller in capacity.

E. Put the affected vSAN host into maintenance mode to physically replace the storage device.

F. Remove the affected Disk from the Disk Group, and choose Full Data Migration.

Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to at least double the usable capacity in their all-flash vSAN cluster.

The vSAN cluster is deployed into a co-located datacenter that is owned by a third-party hosting company. The hosting company charges a fixed monthly cost for rack space and power consumption. The service owner has been given a limited budget for additional hardware purchases, but not for on-going co-location costs.

The current vSAN cluster has the following configuration: 10 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM

1 Disk Group per vSAN node

-1 x 400 GB

-4 x 1.8 TB

De-duplication and Compression is enabled.

vSAN Capacity is currently:

-Total: 72 TB

-Usable: ~40 TB (FTT1/RAID1) and ~60 TB (FTT1/RAID5).

As a result of any action taken, the service owner would like to ensure that overall availability of the vSAN cluster is increased.

Which two recommendations meet the requirement to increase capacity while maintaining service availability? (Choose two.)

A. Install an additional 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.

B. Update the existing Disk Group, and claim the newly installed drives for each node.

C. Create a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.

D. Install an additional 3 x 1.8 TB SSDs per vSAN node.

E. Replace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.

After a vSAN Witness Appliance network configuration, the vSAN administrator notices that vSAN traffic flows from vmk0 (Management Traffic) rather than vmk1 (vSAN Traffic).

Which step should be taken to resolve this issue?

A. Configure vmk0 with IP address on the same range as that of vmk1.

B. Tag the vmk0 for vSAN traffic.

C. Configure vmk1 with IP address on the different network than that of vmk0.

D. Tag the vmk1 for Witness traffic.

An organization has two vSAN clusters managed by the same vCenter Server, each providing 100TB of storage. The first cluster runs at 75% of its storage capacity, and the second cluster runs at 50% of its storage capacity.

The company also has the following:

An iSCSI array of 300TB. which runs at 76% of its capacity A NAS system of 200TB, which runs at 10% of its capacity A Fiber channel (FC) array of 300TB, which runs at 80% of its capacity

The administrator is asked to add an additional 25TB of storage to the first cluster. The administrator 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. Create an HCI Mesh using the first cluster's datastore.

B. Obtain additional free capacity from the existing NAS storage.

C. Obtain additional free capacity from the existing FC storage.

D. Create an HCI Mesh using the second cluster's datastore.
