VMware Advanced VMware Cloud Foundation 9.0 Storage Sample Questions:

1. An administrator needs to monitor an external NFS datastore attached to a VMware Cloud Foundation (VCF) cluster to confirm that it meets latency and throughput targets.
Drag and drop the three correct options to monitor NFS performance from the Options list on the left and place them into the Valid Actions on the right in any order. (Choose three.)

2. A VMware Cloud Foundation (VCF) Management Domain is requested to be deployed with the following information:
. 6 blade style hosts with no local storage beyond the operating system.
. 4 25 Gb networking cards installed in each host.
. A 30 TB external array configured to support NVMe/TCP only.
. 2 dVS switches, one configured for storage isolation and one for all other traffic.
. Aria Operations is not currently deployed in the environment.
Place the general steps in sequence for converging VCF on to this configuration.

3. An administrator is working on a VMware Cloud Foundation (VCF) Workload Domain that was configured to use vSAN for principal storage. The administrator wishes to create and configure a datastore cluster to host tenant VMs using that vSAN backed storage across multiple clusters, mixed OSA and ESA, in the domain.
What should the administrator consider?

A) When using vSAN datastores, Datastore Clusters are not supported. Each VM must be placed manually on the vSAN datastore.
B) A datastore cluster can combine different storage types, such as vSAN, FC, and NFS datastores, as long as they are in the same vCenter; Storage DRS will treat them uniformly.
C) vSAN OSA and ESA based datastores must be added to a datastore cluster tag and then selected as part of a single storage policy.
D) When using vSAN as the underlying datastore, an administrator must create the datastore cluster via vCenter APIs, include the vSAN datastore(s) in it, enable Storage DRS, and ensure the VM Storage Policies reference the appropriate vSAN-capable datastore.

4. An architect is designing a vSAN Original Storage Architecture (OSA) cluster for a VMware Cloud Foundation (VCF) Management Domain. The following details were made available:
* 12 hosts, each host with: 3 x 800 GB NVMe (cache) and 12 x 3.84 TB SAS SSD (capacity).
* Planned configuration: 3 disk groups per host (1 NVMe + 4 SSD each).
* Storage policy: FTT = 2 (RAID-1), Checksum. Deduplication and Compression are Enabled.
* Network: 25 GbE dedicated vSAN network fabric, properly configured for jumbo frames.
After deployment and loading test data to 70% capacity, the operations team reported extended resync times when two hosts are placed into maintenance mode with "Ensure Accessibility" selected and no hardware or network bottlenecks were detected.
How can the administrator explain the observed behavior?

A) "Ensure Accessibility" triggers a full component migration when FTT = 2, regardless of available quorum.
B) Deduplication and compression cause cache-tier contention during resync.
C) NVMe devices in the cache tier limit backend de-staging throughput during resync.
D) With 3 disk groups per host, vSAN introduces additional metadata and resync operations under FTT = 2.

5. In a vSAN ESA cluster, one host goes offline unexpectedly for more than an hour.
When it returns online, vSAN needs to rebuild and restore compliance for several objects that became degraded during the outage.
Drag and drop the three correct options for the automatic recovery process from the Options list on the left and place them into the Valid Actions on the right in any order. (Choose three.)
