VMware 5v0-21-21 practice test

Question 1

An administrator is tasked with sharing storage from one vSAN cluster to another vSAN cluster. SPBM
management must be preserved end-to-end, and the policy must be applied by the source vSAN
cluster which is storing the dat
a. Both vSAN clusters are managed by the same vCenter server.
What should the administrator configure?

• A. NFS volumes on vSAN
• B. iSCSI targets on vSAN
• C. HCI Mesh on vSAN
• D. vVOLs on vSAN

Answer:

C

Question 2

cluster for a customer who is planning to use vRealize Automation to provision 600 virtual machines
into that cluster, with expected growth up to 1,000 VM. Each VM has a 40GB thick-provisioned disk.
Which flash disk size is required for the cache tier per ESXi node to meet all requirements?

• A. 400GB
• B. 700GB
• C. 600GB
• D. 800GB

Answer:

D

Explanation:
40GB x 1000VMs = 40 000 GB total max expected usage 40 000GB / 5 node cluster = 8000 GB per
node cache should be 10% so 800GB SSD is needed. However this question is stupid from real life
perspective. one host can run up to 200 VMs - so what with MM, any failure ? Cluster should be sized
with 6 ESXi hosts minumim

Question 3

An administrator is tasked with preparing for a Cross vCenter migration in a stretched vSAN cluster
where the virtual machines migration will be orchestrated via VMware Site Recovery Manager.
Which action should the administrator take so the migration is successful?

• A. Disable vSAN Deduplication and Compression
• B. Reconfigure vCenter HA Admission control
• C. Enable vCenter Single Sign-On Enhanced Linked Mode
• D. Make sure that Witness traffic is on the management NIC.

Answer:

C

Question 4

An administrator wants to deploy Kubernetes on an end-to-end VMware stack, using VMware vSAN
for storage.
Which VMware product should the administrator install as the Kubernetes platform choice?

• A. VMware Tanzu Kubernetes Grid
• B. VMware Tanzu Data services
• C. VMware Tanzu Build service
• D. VMware Tanzu Mission Control

Answer:

A

There
is a picture with integration with vSAN

Question 5

A company has deployed a 12-node (6-6-1) vSAN 7.0 stretched cluster for all production workloads.
The customer currently uses four different vSAN storage policies for running the workloads
depending on the applications requirements:
* Policy 1 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Erasure Coding
* Policy 2 - Site Disaster Tolerance=Dual Site Mirroring, FTT=Mirroring
* Policy 3 - Site Disaster Tolerance=None - Keep Data on Preferred, FTT=Mirroring
* Policy 4 - Site Disaster Tolerance=None - Keep Data on Non-Preferred, FTT=Mirroring
During the setup of the vSAN stretched cluster, the following VM/Host Rules were created:
* Preferred Site - Preferred Site workloads should run on DC1 hosts.
* Secondary Site - Secondary Site workloads should run on DC2 hosts.
Which two activities should the administrator complete to ensure that there is no impact to
production services during the maintenance window in the Preferred Site? (Choose two.)

• A. Change the Site Disaster Tolerance setting in Policy 3 to be “Dual Site Mirroring”.
• B. Update vSphere DRS site affinity rules so that Preferred Site workloads should not run on hosts in DC1.
• C. Change the Site Disaster Tolerance setting in Policy 4 to be “None - Keep Data on Preferred”.
• D. Change the FTT setting in Policy 3 to be “Erasure Coding”.
• E. Update vSphere DRS site affinity rules so that Preferred Site workloads must run on hosts in DC2.

Answer:

A, E

Question 6

An administrator is planning to deploy workloads on a six node vSAN cluster, and all nodes are
distributed equally across three racks.
Which action is required to ensure that the workload VMs remain compliant with the default vSAN
policy after a complete rack failure?

• A. Add an additional rack with two hosts, and configure vSAN with four fault domains and FTT=1 (erasure coding).
• B. Add two additional hosts per rack, and configure vSAN with three fault domains and FTT=1.
• C. Add an additional host per rack, and configure vSAN with three fault domains and FTT=2.
• D. Add an additional rack with two hosts, and configure vSAN with four fault domains and FTT=1 (mirroring).

Answer:

D

Question 7

An administrator is planning to change a vSAN Storage Policy to apply a Failures To Tolerate (FTT) of
2, using RAID-6.
What is the minimum number of vSAN nodes required?

• A. 6
• B. 4
• C. 5
• D. 8

Answer:

A

Question 8

An administrator is planning to deploy cloud-native workloads onto the vSAN Direct datastore.
Which storage policy structure rule is supported?

• A. Host-based rules
• B. vVOL storage rules
• C. Tag-based placement rules
• D. Storage performance-based rules

C

Question 9

An architect is designing a vSAN cluster.
Which storage controller option will yield optimal performance?

• A. Hugh queue depth
• B. Set caching to 50% read on the controller
• C. Enable battery write-back caching
• D. RAID 0

Answer:

A

Question 10

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
