C. esxcli vsan health cluster list
D. esxcli vsan errands timemachine get
正解：A

質問 4：

正解：B,D

質問 5：
During planned maintenance of a four-node vSAN cluster, an outsourced IT contractor accidentally removed a
2.5" SSD cache disk from one of the vSAN nodes. The storage policy has been configured with FTT=1 RAID
1, and the disk management UI marked the disk group as
Which remediation steps should the administrator select to ensure VMs become compliant with the storage policy as soon as possible?
A. remove disk group > enter host in maintenance > fully evacuate all data > exit maintenance
B. enter host in maintenance > remove from disk group > shutdown host > replace disk > power on host
C. replace the SSD cache disk > rescan > add disk back in disk group
D. vSAN Health Check > retest > object health > repair objects immediately
正解：C

質問 6：

What are two possible reasons the entire disk group is offline? (Choose two.)
A. Two capacity drives in the disk group are offline.
B. Deduplication and compression is enabled on the cluster.
C. The failed drive is configured as a cache drive for the disk group.
D. Data-at-rest encryption is enabled for the disk group.
E. RAID-5/6 (Erase Coding) is one of the failure tolerance methods in use.
正解：A,C

質問 7：
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. The VMs on the vSAN datastore need to be migrated to another datastore as quickly as possible to prevent data loss.
B. A new vCenter can be deployed using the existing KMS profile and associated with the existing vSAN encrypted clusters.
C. The data within the vSAN datastore is lost, if the hosts are powered off.
D. All encrypted disk groups become unmounted and remain offline until vCenter Server is back online.
正解：A

質問 8：
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. Place the hosts Into maintenance mode and update the IP addresses of the current vSAN VMkernel ports to the new subnet.
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. Migrate current vSAN VMkernel ports to a distributed switch and enable vSphere Network I/O Control.
正解：D
