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

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?

• A. vSAN OSA - Hybrid
• B. vSAN ESA Storage Clusters
• C. vSAN ESA
• D. vSAN OSA - All Flash

A financial organization successfully deployed a new Workload Domain in VMware Cloud Foundation (VCF) using NFS storage. All ESX hosts are commissioned and connected to the same storage network. The system administrator is tasked to configure a new NFS datastore in the existing cluster.
Which two steps are correct? (Choose two.)

• A. Configure vSAN on all hosts.
• B. Mount the NFS datastore on each ESX host in the cluster.
• C. Mount the NFS datastore on one ESX host in the cluster.
• D. Create an NFS export on the storage array.
• E. Attach NFS as a secondary datastore.

As part of standard operating procedures, when an administrator leaves the organization, a shallow rekey operation must be performed on a vSAN ESA cluster with vSAN Data-at-Rest Encryption enabled.
Which key is rotated during a shallow rekey operation?

• A. Host Key
• B. Key Derivation Key
• C. Disk Encryption Key
• D. Key Encryption Key

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 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.
• B. vSAN OSA and ESA based datastores must be added to a datastore cluster tag and then selected as part of a single storage policy.
• C. 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.
• D. When using vSAN datastores, Datastore Clusters are not supported. Each VM must be placed manually on the vSAN datastore.
