VMware HCI Master Specialist Sample Questions:
A vSAN administrator is working on a 4 host homogenous vSAN Cluster that has 2 disk groups per host. One of the hosts needs to be permanently removed and repurposed for some other use.
These are the out of order steps which need to be completed:
1. Delete the disk group(s) that reside on the host you want to decommission.
2. Wait for resync traffic to complete and the host to enter maintenance mode.
3. Ensure there is sufficient capacity in the vSAN disk groups to decommission a node.
4. Put the host into maintenance mode with full data migration selected.
5. Move the ESXi host out of the cluster.
What is the correct order?
- A. 4, 3, 2, 5, 1
- B. 3, 1, 4, 2, 5
- C. 3, 4, 2, 1, 5
- D. 4, 3, 2, 1, 5
Correct Answer: C 🗳️
An infrastructure architect is designing a vSAN Cluster that must satisfy these requirements:
* support storage policies with 2 failures - RAID-1 (Mirroring)
* support storage policies with 2 failures - RAID-6 (Erasure Coding)
virtual machines must maintain compliance with the storage policy rules above when one host is in maintenance mode with full data migration What is the minimum number of hosts needed to achieve these design requirements?
- A. 6
- B. 5
- C. 7
- D. 8
Correct Answer: A 🗳️
Reference the exhibit.
A university campus has a site topology illustrated in the exhibit. Adjacent connected buildings are connected with a single 40gb layer 3 network with a RTT of 0.6ms as depicted by each line. An architect wants to configure a fault domain in each building.
What would the architect need change in order to implement a fully supported vSAN Cluster?
- A. Decrease the existing RTT between the existing links by 0.1ms or more.
- B. Enable a single Layer 2 network across all buildings for vSAN connectivity.
- C. Enable IPv6 networks across all buildings for vSAN connectivity.
- D. Add an additional link to the existing adjacent links to make it redundant.
Correct Answer: D 🗳️
A vSAN disk group contains one cache drive and four capacity drives. A drive that belongs to this disk group has failed. The entire disk group containing the failed drive is offline.
What are two possible reasons the entire disk group is offline? (Choose two.)
- A. The failed drive is configured as a cache drive for the disk group.
- B. Two capacity drives in the disk group are offline.
- C. Deduplication and compression is enabled on the cluster.
- D. Data-at-rest encryption is enabled for the disk group.
- E. RAID-5/6 (Erase Coding) is one of the failure tolerance methods in use.
Correct Answer: A,B 🗳️
A 4-node vSAN cluster has a single disk group per host. An administrator wants to increase the capacity of the vSAN datastore by adding a second disk group to each host in the cluster. The newer drives intended for the second disk group are certified and in compliance with VMware Compatibility Guide (VCG). However, the newer devices procured are of a different make and model than the existing disk group composition.
Considering the scenario, which statement is true?
- A. This configuration is supported, however a separate controller is mandatory for each disk vendor.
D18912E1457D5D1DDCBD40AB3BF70D5D - B. This configuration is supported, however performance may vary across disk groups.
- C. The Capacity Tier devices need to be the same make and model as other disk groups.
- D. The Cache Tier devices need to be the same make and model as other disk groups.
