VMware Advanced VMware Cloud Foundation 9.0 Storage - 3V0-23.25 Exam Questions
QUESTION NO: 1
An agency is designing its secure private cloud on VMware Cloud Foundation with the following requirements:
* Strict data segregation between the management and workload domains.
* Company policy prevents using vSAN as a storage solution.
* Data encryption at rest is mandatory for both the management and workload domains.
* Data encryption in transit is mandatory for the workload domains.
* Data-at-rest encryption must be performed by the storage array and not rely on VMware native or vSAN- specific mechanisms.
* Allow for automated VM placement, operational integrity with VCF Operations, and assurance that file- based workloads scale efficiently.
Which storage architecture fulfills these technical and regulatory requirements?

QUESTION NO: 2
An administrator is responsible for a VMware Cloud Foundation (VCF) Private Cloud and has been tasked with identifying and explaining the different Fibre Channel (FC) Storage Area Network (SAN) components within a VCF Workload Domain cluster.

Drag and drop the correct Term onto its matching Definition.
Correct Answer:
Explanation:
LUN Masking = A security process performed on the storage array by which specific storage components are hidden to prevent unauthorized access to data; Datastore Cluster = A collection of shared resources with a shared management interface that enables resource allocation policies; SAN Fabric = A dedicated high-performance network infrastructure for storage devices; Datastore = A manageable storage entity used as a repository for Virtual Machine files including log files, scripts, configuration files and virtual disks; Host Bus Adapter (HBA) = Added to an ESX host server to allow the host access to the dedicated storage area network; Zoning = A security process completed on the Storage Area Network to ensure only certain devices can communicate with each other.
These definitions describe the core components of a Fibre Channel SAN design in a VCF Workload Domain. LUN masking is performed on the storage array and controls which hosts can see specific LUNs, preventing unauthorized access to storage. A datastore cluster is a collection of datastores managed as a shared resource pool, allowing placement and balancing policies through Storage DRS. A SAN fabric is the dedicated high-performance network that interconnects ESX hosts, Fibre Channel switches, and storage arrays. A datastore is the vSphere logical storage container where VM configuration files, virtual disks, logs, and related files reside. A Host Bus Adapter is the physical or virtual adapter in the ESX host that connects the host to the Fibre Channel storage area network.
Zoning is performed on the Fibre Channel fabric and controls which initiators and targets can communicate. Together, zoning and LUN masking provide layered access control, while datastores and datastore clusters provide the vSphere consumption model. Reference topics: Fibre Channel SAN Concepts, SAN Fabric, Zoning, LUN Masking, VMFS Datastores, Datastore Clusters.
QUESTION NO: 3
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?

QUESTION NO: 4
An administrator is tasked with deploying a vSAN ESA Stretched Cluster for a VMware Cloud Foundation (VCF) workload domain. The stretched cluster must meet the following requirements:
* Ensure the cluster supports a storage policy with a secondary level of resilience of FTT=2 using RAID-6 erasure coding.
* Allow vSAN to regain its prescribed level of resilience in the event of a sustained host outage.
What is the minimum number of hosts required in each availability zone?

QUESTION NO: 5
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.)

QUESTION NO: 7
A customer attaches an external Fibre Channel (FC) VMFS datastore to a VMware Cloud Foundation (VCF) workload domain for backup staging. The administrator must confirm that the datastore is visible to all hosts, and that path and device health alarms will trigger should a fabric link or path fail.
Which action should the administrator take to verify this?

QUESTION NO: 8
An administrator just built a new workload domain including a vSAN ESA cluster. The architecture design included the use of memory tiering and a specific smaller NVMe device has been installed in each ESX host for this purpose.
When looking in the vSphere UI, the administrator notices that the device intended to be used for memory tiering has been claimed by vSAN.
What action should be taken on each host to achieve the desired configuration?
