Advanced VMware Cloud Foundation 9.0 Storage (3V0-23.25) Free Practice Test

Question 1

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. 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.

B. When using vSAN datastores, Datastore Clusters are not supported. Each VM must be placed manually on the vSAN datastore.

C. 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.

D. vSAN OSA and ESA based datastores must be added to a datastore cluster tag and then selected as part of a single storage policy.

Correct Answer: B

Question 2

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

Question 3

An administrator is deploying a vSphere Supervisor Cluster on a VMware Cloud Foundation (VCF) Workload Domain that uses NFS storage. As part of the configuration, the administrator must define separate storage policies for container images, ephemeral volumes, and persistent volumes within the vSphere Namespace.
The solution must align with vSphere Storage Policy Based Management (SPBM) and Broadcom TechDocs recommendations for supported Supervisor configurations.
Which configuration meets these requirements?

A. Create three distinct SPBM storage policies mapped to shared NFS datastore(s). Assign the policies to the corresponding storage options for container images, ephemeral volumes, and persistent volumes.

B. Create three SPBM storage policies that all reference the same shared NFS datastore. Assign these policies respectively to container images, ephemeral volumes, and persistent volumes when enabling Workload Management to logically isolate the volume types within a single datastore.

C. Use datastore clusters to automatically balance storage consumption for container and persistent volumes, and rely on vSphere DRS to place ephemeral data dynamically across datastores.

D. Define one default storage policy and allow the Supervisor control plane to automatically create sub- policies for container and persistent workloads during namespace provisioning.

Question 4

An administrator notices alerts triggering IOPS and Disk Throughput storage performance problems in the Fibre Channel datastore in a VMware Cloud Foundation (VCF) Workload Domain.
What can the administrator review to identify which Virtual Machines (VMs) may be experiencing storage IOPS and disk throughput performance issues?

A. Storage Operations page.

B. vSAN Health dashboard.

C. vSphere Storage Inventory dashboard.

D. Live! vSphere Heavy Hitter VM dashboard.

Question 5

An administrator is preparing to enable vSAN Data-at-Rest Encryption and must verify that the identity and key provider prerequisites are met before proceeding with the configuration.
Which two requirements must be met? (Choose two.)

A. OSA requires a trusted KMS identity before encryption can be enabled.

B. OSA does not support external KMS integration.

C. OSA requires Trusted Platform Modules (TPMs).

D. ESA requires a trusted KMS identity before encryption can be enabled.

E. ESA requires Trusted Platform Modules (TPMs).

Question 6

A multinational corporation is deploying a VMware Cloud Foundation (VCF) Workload Domain cluster to host tier-1 business applications with the following requirements:
* Deliver high performance to all workloads.
* Integration with automated VM placement.
* Reuse of existing infrastructure including multiple Fibre Channel (FC) arrays partitioned by business unit.
* The storage architecture must avoid vSAN.
* Meet organizational separation requirements.
Which two deployment approaches meet these requirements? (Choose two.)

A. Configure shared VMFS datastores on an assigned FC array as supplemental storage.

B. Configure dedicated VMFS datastores on assigned FC arrays as principal storage.

C. Configure shared VMFS datastores on an assigned FC array as principal storage.

D. Configure a shared VMFS datastore on an assigned FC array as principal storage.

E. Configure dedicated VMFS datastores on assigned FC arrays as supplemental storage.

Question 7

An administrator is responsible for managing a VMware Cloud Foundation (VCF) Private Cloud.
The following information has been provided about the environment:
* There are 3 customer datacenters, Site A, Site B and Site C.
* The datacenter at Site A runs all Production Services.
* The datacenter at Site B has reached capacity and there is no space for additional physical hardware.
* The datacenter at Site C has been commissioned to replace Site B, because there is more rack space and power capacity to cater for future demand.
The administrator has been tasked with identifying the networking requirements for a new VMware vSAN Stretched Cluster with the following requirements:
* The solution will deploy a total of 10 new ESX host servers to create a VMware vSAN Stretched Cluster.
* The solution must deploy appropriate networking to ensure minimal disruption from issues with Spanning Tree Protocol (STP).
Drag and drop the correct vSAN Site Type, Networking Type and Round Trip Latency (RTT) within the boxes provided to complete the high-level diagram.

Correct Answer:

Explanation:
Site A = Data Site; Site B = Witness Site; Site C = Data Site; Site A # Site C = Layer 3, RTT < 5 ms; Site A # Site B = Layer 3, RTT < 200 ms; Site B # Site C = Layer 3, RTT < 200 ms Site A and Site C should be the data sites because Site A hosts production services and Site C has been commissioned to replace the capacity-constrained Site B. Site B should be used as the witness site because it has no space for additional physical hosts, and a vSAN witness appliance does not run workload VMs. A vSAN Stretched Cluster requires two availability zones for data nodes and a third site for the witness appliance. The data-site-to-data-site connection carries synchronous vSAN data traffic and must meet less than 5 ms RTT. The witness site carries metadata traffic only, so the data- site-to-witness links support higher latency, with less than 200 ms RTT for up to 10 hosts per site.
Because the requirement specifically calls out minimizing disruption from STP, Layer 3 is the preferred network type between sites. VMware states that Layer 3 helps avoid STP redirecting traffic across undesirable links, such as constrained witness links.

Question 8

The security team has notified the VMware Cloud Foundation (VCF) Storage Administrator of a new security vulnerability that must be patched immediately. The vSAN Cluster uses vSphere Lifecycle Manager images.
After updating the image with the patch, what method should the administrator use to apply this patch with the least amount of disruption to the cluster?

A. Disable the Quick Boot feature in the host remediation settings for the images.

B. Disable HA admission control in the host remediation settings for the baselines.

C. Enable the Quick Boot setting in the host remediation settings for the images.

D. Enable the suspend to memory feature in the host remediation settings for the baselines.
