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

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 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 5

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.
