A company Is using vSAN Data At Rest Encryption. vCenter is placed on a separate management cluster with external storage. The external storage system has suffered from a disk error and the vCenter Server restore from backup has been unsuccessful, due to media errors.
Considering the scenario, which statement Is true?

• A.A new vCenter can be deployed using the existing KMS profile and associated with the existing vSAN encrypted clusters.
• B.All encrypted disk groups become unmounted and remain offline until vCenter Server is back online.
• C.The VMs on the vSAN datastore need to be migrated to another datastore as quickly as possible to prevent data loss.
• D.The data within the vSAN datastore is lost, if the hosts are powered off.

A vSAN disk group contains one cache drive and four capacity drives. A drive that belongs to this disk group has failed. The entire disk group containing the failed drive Is offline.
What are two possible reasons the entire disk group Is offline? (Choose two.)

• A.Two capacity dnves in the disk group are offline.
• B.Data-at-rest encryption is enabled for the disk group.
• C.Deduplication and compression is enabled on the cluster.
• D.The failed drive is configured as a cache drive for the disk group.
• E.RAID-5/6 (Erase Coding) is one of the failure tolerance methods in use.

A company has reserved the last Saturday of the month to conduct server maintenance. An administrator is allowed to perform maintenance from 5 AM to 12 PM. During the upcoming maintenance window, the administrator will upgrade the controller driver, controller firmware, and vSphere version.
Environment details:
* vCenter is already at the latest version
* 5 node vSAN cluster
* The VMs are using a mix of RAID-0, RAID-1, and RAID-5 policies
* Each node is storing 20 TBs worth of VMs
Which maintenance mode option will allow an administrator to successfully perform the required upgrades, while ensuring all VMs remain online?

• A.Full data migration
• B.No Data Migration
• C.Ensure Accessibility
• D.Admission Control Enabled

An administrator Is reassessing subnet use in preparation for migrating existing vSAN Clusters to a new subnet.
Which steps should the administrator perform to ensure all VMs remain online during the vSAN network subnet migration?

• A.Migrate current vSAN VMkernel ports to a distributed switch and enable vSphere Network I/O Control.
• B.Migrate the VMs using Storage vMotion off the vSAN datastore and rebuild a new vSAN Cluster using the new subnet.
• C.Add a second VMkernel port on the new subnet for all hosts and remove original vSAN VMkernel ports.
• D.Place the hosts Into maintenance mode and update the IP addresses of the current vSAN VMkernel ports to the new subnet.

The vSAN Health Check 'Hosts disconnected from vCenter Server' is reporting an error state for one host in the vSAN Cluster. All other health checks in the Network category are in a green state.
Which VMware recommended remediation task should be taken by the administrator?

• A.Right-click the affected host and click Remove from Inventory.
• B.Configure a vSAN-enabled VMkernel port on the affected host.
• C.Restart the vSAN Management Daemon.
• D.Right-click the affected host and click Connection > Connect.
