VMware Specialist: vSAN 6.x Exam (2VB-601) Free Practice Test

Question 1

Consider the following vSAN stretched cluster scenario:
* Site A is the preferred site, Site B is the secondary site
* Site C is running the vSANwitness host virtual appliance
* A virtual machine named VM01 is located on the vSAN datastore
* VM01 is running on a host at SiteB
* The vSAN default storage policy is assigned to VM01
* The vSAN default storage policy has NOT been modified
* All aspects of the cluster are functioning properly
Where are reads and writes for VM01 performed?

A. Reads are performed at Site B, writes are performed synchronously at Site A and Site B.

B. Reads are performed at Site B, writes are performed at Site B.
Changes to Site B are replicated asynchronously to Site A through the vSAN witness host.

C. Reads and writes are performed at Site A since it is the preferred site. Changes to Site A are replicated asynchronously to Site B

D. Reads and writes are performed at Site A and Site B using a round-robin algorithm.

Correct Answer: C

Question 2

What is the VMware-recommended network configuration between the three sites in a vSAN stretched cluster?

A. L3 connectivity between all three sites.

B. L2 connectivity between the preferred and secondary sites, and L3 from the preferred and secondary sites to the witness site.

C. L2 connectivity between all three sites.

D. L3 connectivity between the preferred and secondary sites, and L2 from the preferred and secondary sites to the witness site.

Correct Answer: B

Question 3

An administrator is deploying vSAN 6.6.
What must the administrator configure to set up vSAN networking?

A. A vSAN VMkernel port on each host in the cluster

B. IGMP snooping on the switch

C. A class A network address

D. A matching subnet mask on all vSAN VMkernel ports

Question 4

An administrator is designing a vSAN cluster for a number of new workloads. The design calls for the use of erasure coding with RAID 5.
Which statement is true about what is needed to meet the needs of this scenario?

A. An all-flash configuration is required.

B. Six nodes are required at a minimum.

C. vSAN Enterprise licensing is required

D. vSAN Standard licensing is sufficient

Question 5

In a vSAN stretched cluster with Primary level to tolerate set to 1 and Secondary level of failure to tolerate set to 2, what is the maximum amount of space that a 100GB virtual disk could consume without any other policy rules set?

A. 600GB

B. 400GB

C. 100GB

D. 200GB

Question 6

Which two vSAN configurations require the use of a witness appliance? (Choose two.)

A. two-node configuration

B. all-flash configuration

C. stretched cluster configuration

D. hybrid configuration

Correct Answer: A,C

Question 7

A 12-node vSAN cluster has been deployed across three server racks in a data center.
* There are four nodes in each server rack.
* A vSAN fault domain has been configured for each server rack for a total of three fault domains.
* All virtual machines in the cluster have the vSAN default storage policy assigned to them.
* This policy has not been modified.
* vSphere HA is enabled for the cluster.
* One of the server racks loses power.
How does this affect virtual machines running on this cluster?

A. All virtual machine data remains accessible. Virtual machines running on nodes in the failed server rack are restarted on nodes in the other two server racks. Virtual machines in the other two server racks continue to run.

B. Virtual machines running on nodes in the failed server rack remain offline for 60 minutes. Virtual machines in the other two server racks continue to run and are marked "Degraded".

C. Since there are four nodes in each server rack, erasure coding is used to rebuild data that was lost due to the server rack power failure. vSphere HA monitors the rebuild process and powers on all affected virtual machines after the rebuild process is complete.

D. Virtual machine data in the failed server rack is rebuilt immediately using parity information. vSphere HA powers off and restarts all of the virtual machines to rebalance storage utilization across the cluster.

Correct Answer: A

Question 8

What is the purpose of the cache tier in an all-flash vSAN cluster?

A. 20% write caching and 70% read caching and 10% checksum metadata.

B. Read caching only.

C. Write caching only.

D. 30% write caching and 70% read caching.

Question 9

An administrator is designing a vSphere cluster with the VSAN default policy. The requirement is to maintain full redundancy of data and virtual disks during any patching or maintenance of this cluster.
What is needed to meet the needs of this scenario?

A. Use of RAID-5/6 erasure coding

B. Multiple disk groups per host

C. VMware Proactive HA

D. A minimum of four hosts in the cluster

Question 10

What must be enabled for the vSAN online health feature to function?

A. Proactive Tests Service

B. Customer Experience Improvement Program

C. vRealize Operatons vSAN Status Plugin

D. vSphere Proactive HA

Correct Answer: B
