5V0-21.21 Online Practice Questions and Answers

An architect needs to automate an infrastructure that supports VMware Horizon as well as VMware Tanzu. Which solution mandates the use of VMware vSAN?

A. VMware Cloud Foundation

B. VMware Horizon

C. VMware Tanzu

D. VMware vRealize Automation

A customer is planning to deploy a vSAN cluster to host their in-house distributed ERP system. The hardware specifications for their server nodes include:

2 x Intel Xeon CPU E5-2697 v3 @ 2.60GHz 1TB memory

Which boot device is supported for the vSAN ESXi nodes for this customer?

A. A 16GB single-level cell (SLC) SATADOM device must be used.

B. A 4GB USB or SD device must be used.

C. A 16GB multiple-level cell (MLC) SATADOM device must be used.

D. ESXi Hosts must boot from a PMEM device.

An architect is designing for a production vSAN cluster, and the customer introduced these requirements

related to File Services:

A minimum of 12 files shares.

30TB NFS capacity to mount workload VMs.

What should be the architect's recommendations?

A. Point out the risks regarding putting the hosts in maintenance mode in terms of FSVM.

B. Confirm on all of the requirements and move forward with the physical design.

C. Raise concerns regarding support when running VMs on an NFS share as risk.

D. Highlight the required number of nodes required for the vSAN cluster as a constraint.

Due to the success of the recently deployed developer-only private cloud solution, a company has a new requirement to at least double the usable capacity in their all-flash vSAN cluster.

The vSAN cluster is deployed into a co-located datacenter that is owned by a third-party hosting company. The hosting company charges a fixed monthly cost for rack space and power consumption. The service owner has been given a limited budget for additional hardware purchases, but not for on-going co-location costs.

The current vSAN cluster has the following configuration: 10 vSAN Nodes with 2 CPUs (20 cores), 512 GB RAM

1 Disk Group per vSAN node

-1 x 400 GB

-4 x 1.8 TB

De-duplication and Compression is enabled.

vSAN Capacity is currently:

-Total: 72 TB

-Usable: ~40 TB (FTT1/RAID1) and ~60 TB (FTT1/RAID5).

As a result of any action taken, the service owner would like to ensure that overall availability of the vSAN cluster is increased.

Which two recommendations meet the requirement to increase capacity while maintaining service availability? (Choose two.)

A. Install an additional 400 GB SSD and 4 x 1.8 TB SSDs per vSAN node.

B. Update the existing Disk Group, and claim the newly installed drives for each node.

C. Create a new Disk Group, and claim the newly installed cache and capacity SSD drives for each node.

D. Install an additional 3 x 1.8 TB SSDs per vSAN node.

E. Replace existing SSDs with an 800 GB SSD and 4 x 3.8 TB SSDs per vSAN node.

After a vSAN Witness Appliance network configuration, the vSAN administrator notices that vSAN traffic flows from vmk0 (Management Traffic) rather than vmk1 (vSAN Traffic).

Which step should be taken to resolve this issue?

A. Configure vmk0 with IP address on the same range as that of vmk1.

B. Tag the vmk0 for vSAN traffic.

C. Configure vmk1 with IP address on the different network than that of vmk0.

D. Tag the vmk1 for Witness traffic.

A cache disk failure marked a vSAN disk group as failed, and the data is being rebuilt on other disk groups.

Which action should the vSAN administrator take to reduce the negative impact on the VMs?

A. Enabling Resync Throttling

B. Enabling Maintenance mode with no data evacuation

C. Enabling automatic rebalance

D. Setting the vSAN policy's IOPS limit for object value to 0 (unlimited)

An administrator managing a vSAN cluster of six-nodes with policy FTT-2/RAID-6 decided to put one of the nodes in maintenance mode using the “Full-data migration” option.

What will happen after this action is taken?

A. The host will enter in maintenance mode and the data will remain accessible until the host exits maintenance mode.

B. The system will prompt to add an additional host to the cluster in order to preserve the policy compliance.

C. The host will enter in maintenance mode and only data with no redundancy will remain accessible.

D. The host will enter into maintenance mode if both components of a certain object are residing on that host, then one of the components will be moved to another available host.

An architect is working with vSAN and setting the fault domains to support FTT=1. How many fault domains will be needed?

A. 2

B. 3

C. 4

D. 1

A customer is planning to migrate their physical Microsoft SQL Server clustered workloads to vSAN enabled vSphere clusters.

The following requirements must be met:

Each MSSQL cluster is made up of 3 nodes Highest possible availability against node failures Some of the vSAN clusters will only consume storage

What should the architect recommend?

A. vSAN iSCSI Target Service

B. Stretched vSAN Cluster

C. vSAN Direct

D. vSAN File Services

An administrator of “vsan-prod” cluster noticed the witness components of VMs are flagged as absent after a failed attempt to replace the vSAN Witness Host.

Which action should the administrator take to resolve this issue?

A. Upgrading the vSAN on-disk format

B. Running the vSAN Skyline Health check to ensure there are vSAN Object Health errors and executing the Repair Object Immediately option

C. Using the RVC command: vsan.resync_dashboard ~/computers/vsan-prod

D. Placing the vSAN Witness Host in Maintenance Mode and adding to the vSAN cluster
