Question 1

A storage administrator is being presented with the following VMware Cloud Foundation (VCF) architectural details: • The applications data will require 2.5 PB of capacity. • The production applications will be hosting archival solutions and gateways. • There will be some applications deployed for the purpose of testing and development. What is the optimal principal storage that the administrator can recommend?

Options :

A : vSAN ESA Storage Clusters

B : vSAN ESA

C : vSAN OSA - All Flash

D : vSAN OSA - Hybrid

Answer: A

Question 2

A storage architect is designing a vSAN solution that enforces quotas and Access Based Enumeration (ABE) on all file shares. What should the architect highlight as a design decision implication?

Options :

A : When creating the share, enable quotas and ABE under SMB settings.

B : Quotas are supported only on NFS shares; ABE is supported only on SMB shares.

C : Deploy separate file services servers, one for quotas and one for ABEs.

D : Quotas and ABEs must be configured at a cluster level and not per-share.

Answer: A

Question 3

An administrator reports that after rebooting one host in a vSAN cluster configured with Data-at-Rest Encryption using an external Key Management Server (KMS), the host shows all vSAN disk groups as unmounted. The KMS is online and reachable from all hosts. In vCenter, the host displays the following event: “Failed to retrieve encryption key from KMS.”Key ID: All other hosts in the cluster remain healthy and show “Encryption: Enabled.” Why did the encryption key retrieval fail for this host?

Options :

A : The host’s trust relationship or certificate with the KMS is invalid or missing.

B : The cluster requires a Deep Rekey operation to restore access to the encrypted disks.

C : The vCenter Server has not been restarted to refresh the encryption key cache.

D : The TPM on the host failed to unlock the data encryption keys.

Answer: A

Question 4

A cache drive failed on one of the vSAN OSA nodes in the cluster. When the drive failed, vSAN started a resync to ensure the health of the data, and all objects are showing a healthy and compliant state. The vSAN administrator needs to replace the failed cache drive. Which set of steps should the vSAN administrator take?

Options :

A : Place the disk group into maintenance mode, and select Full Data Migration. Then, physically replacethe failed cache device. Afterwards, vSAN will rebuild the disk group automatically.

B : Physically replace the failed cache device, and vSAN will automatically allocate the storage.

C : Remove the existing vSAN disk group, and physically replace the device. Then, check to verify that theESX host automatically detects the new device. Afterwards, manually recreate the Disk Group.

D : Physically replace the failed cache device, and vSAN will automatically create a new disk group. Then,remove the disk group with the failed device.

Answer: C

Question 5

An architect is presented with the following requirements for the storage solution in a VMware Cloud Foundation (VCF) Workload Domain.The solution must: • Allow for rapid recovery in case of an availability zone failure. • Provide an extremely high amount of IOPS to all applications. • Allow for additional storage to be added as application needs grow. • Provide the lowest latency possible for configured applications. • Provide recovery in case of datastore failure. • Encrypt data in transit and at rest. What two vSAN advanced technologies must be deployed to meet these requirements? (Choose two.)

Options :

A : vSAN File Service

B : vSAN Storage Cluster

C : vSAN Stretched Clusters

D : vSAN Data Protection Service

E : vSAN iSCSI Target Service
