VMware Advanced VMware Cloud Foundation 9.0 Storage Sample Questions:

1. A storage architect has been called into a meeting with the accounting team who is trying to determine why
20% of their raw capacity is not available for consumption. Their vSAN cluster was created with the following characteristics:
* 2 x 2 TB NVMe disks in 6 hosts in their vSAN cluster.
* FTT=1, RAID-1 for the default policy.
* Host Rebuild Reserve not activated for this cluster.
Which two items should the Architect say accounts for most of the unusable capacity? (Choose two.)

A) Operational Reserve (policy changes, rebalancing, data movement)
B) RAID Overhead
C) VM swap overhead
D) Encryption overhead
E) Host upgrade overhead

2. An architect is designing a vSAN storage solution for a remote site. The following requirements have been given:
* There is enough rack space for two hosts, each with 36 CPU cores and 256 GB of RAM.
* The physical network at the remote site supports 10 Gb maximum.
* The network connecting the remote site to corporate has 10 Gb of bandwidth with an average RTT of 25 ms.
* High availability is expected for all the Virtual Machines running at the remote site.
* The solution must provide additional storage to 16 graphic design Windows based workstations.
* Active Directory is configured and available at the remote site.
* The graphic design application requires native NTFS permissions.
What vSAN advanced technology is required for configuring this remote site?

A) vSAN File Share NFSv3 services
B) vSAN File Share SMB services
C) vSAN HCI Mesh
D) vSAN Storage Cluster

3. A vSAN ESA cluster experienced a host NVMe failure, causing several objects to become non-compliant.
Select the steps vSAN ESA follows to detect, evaluate and repair the non-compliant objects.
Drag and drop the four correct options from the Options list on the left and place them into the Required Options on the right in any order. (Choose four.)

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

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?

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