An administrator has been tasked to reboot a node in an encrypted vSAN cluster. The vSAN disk groups on that node become locked after rebooting the node.

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.

C. Replace the caching device in each affected disk group.

D. Run /etc/init.d/vsanvpd restart to rescan the VASA providers.

A company hosts a vSAN 7 stretched cluster for all development workloads. The original sizing of a maximum of 250 concurrent workloads in the vSAN cluster is no longer sufficient and needs to increase to at least 500 concurrent workloads within the next six months.

To meet this demand, the original 8-node (4-4-1) cluster has recently been expanded to 16 nodes (8-8-1).

Which three additional steps should the administrator take to support the current growth plans while minimizing the amount of resources required at the witness site? (Choose three.)

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.

F. Configure the new vSAN witness as a shared witness appliance.

An administrator wants to check the performance metrics for the workloads and their virtual disks that are running on a vSAN cluster, but no statistical charts are displayed in the vSphere client.

Why is this behavior being seen?

A. vSAN network diagnostic mode is not enabled.

B. vSAN proactive tests haven't been run yet.

C. vSAN performance service is turned off.

D. vSAN performance verbose mode is not enabled.

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.

During a vSAN design workshop, an architect collected these customer requirements:

Leverage vSAN storage policies with Erasure Coding.

Enable Deduplication and Compression.

Use the minimum number of hosts in the cluster.

Maintain full storage policy compliance when two nodes are down.

Which vSAN cluster design meets the customer's requirements?

A. Five nodes All-Flash vSAN cluster

B. Six nodes All-Flash vSAN cluster

C. Six nodes Hybrid vSAN cluster

D. Five nodes Hybrid vSAN cluster

An administrator wants to enable encryption on an existing vSAN cluster that already contains virtual machines.

Which additional step should the administrator take to ensure no data is lost during the encryption process?

A. Select ‘Erase disks before use’ check box when enabling encryption on a vSAN cluster.

B. Make vCenter Server trust the KMS, either by trusting the KMS or by uploading a KMS certificate.

C. Ensure that the vSAN Encryption is enabled by default on the existing cluster to encrypt old and new data.

D. Disable vSphere Distributed Resources Schedule (DRS) on the vSAN cluster.

An administrator managing a vSAN cluster of six-nodes with policy FTT-2/RAID-6 decided to put one of the nodes in maintenance mode using the “Full-data migration” option.

What will happen after this action is taken?

A. The host will enter in maintenance mode and the data will remain accessible until the host exits maintenance mode.

B. The system will prompt to add an additional host to the cluster in order to preserve the policy compliance.

C. The host will enter in maintenance mode and only data with no redundancy will remain accessible.

D. The host will enter into maintenance mode if both components of a certain object are residing on that host, then one of the components will be moved to another available host.

An administrator is tasked with preparing for a Cross vCenter migration in a stretched vSAN cluster where the virtual machines migration will be orchestrated via VMware Site Recovery Manager.

Which action should the administrator take so the migration is successful?

A. Disable vSAN Deduplication and Compression

B. Reconfigure vCenter HA Admission control

C. Enable vCenter Single Sign-On Enhanced Linked Mode

D. Make sure that Witness traffic is on the management NIC.

An administrator is tasked with sharing storage from one vSAN cluster to another vSAN cluster. SPBM management must be preserved end-to-end, and the policy must be applied by the source vSAN cluster which is storing the data. Both vSAN clusters are managed by the same vCenter server.

What should the administrator configure?

A. NFS volumes on vSAN

B. iSCSI targets on vSAN

C. HCI Mesh on vSAN

D. vVOLs on vSAN
