VMware Advanced VMware Cloud Foundation 9.0 Storage Sample Questions:

1. An administrator wants to protect a site from disaster and re-protect after fail-over. Industry regulations require to change the primary site every six months.
Which two options are required during the inventory mapping and while running the recovery plans to fulfill this requirement? (Choose two.)

A) Extend the network between both sites.
B) Once the fail-over is successful, re-protect from VMware Live Site Recovery.
C) Use "Prepare reverse mappings" during inventory mapping creation.
D) Use a test recovery plan.
E) Once fail-over is successful, reconfigure vSAN data protection to reverse replication.

2. A VMware Cloud Foundation (VCF) environment runs mixed workloads (Online Transaction Processing (OLTP) + analytics), with the following vSAN configuration:
* 8 hosts (all-flash), ESA enabled.
* Each host: 2 x 3.2 TB NVMe devices.
* Compression is Enabled.
* Checksum is Enabled.
* Storage Policy: FTT=1 (RAID-5/6), Failures to Tolerate = 1 and Object Space Reservation = 0%.
During peak OLTP load, vSAN resync I/O and backend congestion increase latency despite having sufficient network bandwidth.
What is the direct action the administrator can perform to improve write performance while maintaining data protection compliance?

A) Increase object reservation to 100% to pre-allocate capacity and prevent log-structuring overhead.
B) Increase FTT to 2 with RAID-5/6 and disable compression.
C) Disable checksums to reduce metadata writes on NVMe devices.
D) Convert policy to RAID-1 (FTT=1) for latency-sensitive workloads while keeping compression enabled.

3. An enterprise is planning to deploy a new vSAN ESA enabled cluster to their existing VMware Cloud Foundation (VCF) Private Cloud Workload Domain. The following requirements have been given:
* 2 x 4 TB NVMe disks per host
* FTT=1/RAID-5 for all deployed Virtual Machines
* Expected dedupe/compression ratio = 1.5 (50%)
* Reserve enough capacity to rebuild a host completely in case of a failure (Host Rebuild Reservation)
* Operational Reserve of 10%
* Expected overhead for filesystem, object, etc. of 25%
How many hosts are required to meet a minimum usable capacity of 12 TB?

A) 6 hosts
B) 3 hosts
C) 4 hosts
D) 5 hosts

4. An architect has been tasked with designing a vSAN OSA storage solution for a VMware Cloud Foundation (VCF) Private Cloud. The following requirements and constraints have been gathered from the client:
* 2 x 4 TB NVMe disks per host
* 6 hosts
* FTT=1/RAID-5 for all deployed Virtual Machines
* Expected Dedupe/Compression Ratio = 2 (100%)
* Reserve enough capacity to rebuild a host completely in case of a failure (Host Rebuild Reservation)
* Operational Reserve of 10%
* Expected Overhead for Filesystem, Object, etc. of 25%
What is the approximate expected usable capacity of the resulting array?

A) 48 TB
B) 40 TB
C) 24 TB
D) 32 TB

5. Select the storage capabilities supported for use with persistent volumes in the VMware Kubernetes Service (VKS) in VMware Cloud Foundation (VCF).
Drag and drop the five supported capabilities from the vSphere Storage Capabilities list on the left and place them into the Supported Storage Capabilities list on the right in any order. (Choose five.)
