Question 1

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

Answer: B,C

Question 2

An administrator is troubleshooting a vSAN performance issue. In the vSAN cluster performance charts there is a high latency on the vSAN cluster. What is a possible cause of the performance issue?

Options :

A : The Virtual Machines are using PVSCSI controllers.

B : Jumbo frames are enabled on the VMkernel adapters.

C : Erasure Coding is disabled in the storage policy.

D : There is congestion in one or more disk groups.

Answer: D

Question 3

An administrator is tasked with setting up immutable snapshots for recovery in case of a cyber-attack. Which two limitations apply when configuring immutable snapshots? (Choose two.)

Options :

A : The Virtual Machine cannot be part of multiple protection groups.

B : The protection group cannot have more than 7 snapshot schedules.

C : Virtual machine hardware cannot be changed on VM having immutable snapshots.

D : Virtual Machine hardware must be at least version 10.

E : The protection group cannot be both replicated and immutable.

Answer: C,E

Question 4

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 5

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
