Question 1 of 100
Which two vSAN Health Check items are included for vSphere Update Manager integration? (Choose two.)
Answer

Suggested Answer

The suggested answer is A, D.

When considering the integration of vSAN Health Check items with vSphere Update Manager, two crucial components come into play: the vSAN build recommendation and ensuring the vSAN release catalog is up-to-date. The vSAN build recommendation helps identify the appropriate builds needed for maintaining compatibility and stability within the environment, which is essential for effective updates and maintenance. The vSAN release catalog being up-to-date ensures that all the latest software and patches are available for deployment, which is integral to maintaining system health and performance. Therefore, these two items are included in the vSAN Health Check items for vSphere Update Manager integration.

Question 2 of 100
What is a benefit of using vSphere Distributed Switches in a vSAN network?
Answer

Suggested Answer

The suggested answer is A.

A vSphere Distributed Switch simplifies network abstraction, which eases network management by abstracting the underlying hardware. This allows for centralized control and administration of networking across multiple hosts, reducing the manual configuration required and minimizing the potential for errors. Additionally, Distributed Switches support advanced networking features and ensure consistent network configurations across the environment, making them highly beneficial for a vSAN network.

Question 3 of 100
A single disk in a vSAN disk group suffers from an unrecoverable hardware failure. This causes vSAN to set the health status for all disks in the group to
Permanent disk loss, indicating disk failure.
Assuming all other disks have not suffered from a hardware failure, why would vSAN mark all disks in the group as failed?
Answer

Suggested Answer

The suggested answer is D.

If deduplication and compression are enabled on a vSAN cluster, an unrecoverable hardware failure in any single disk of a disk group causes the entire disk group to be marked as failed. This is because deduplication and compression introduce dependencies across all disks within the group, and failure of one disk disrupts the integrity of the entire deduplication and compression process.

Question 4 of 100
In stretched clusters, what is a benefit of implementing a virtual witness rather than a physical witness?
Answer

Suggested Answer

The suggested answer is A.

A virtual witness in a stretched cluster benefits from reduced vSphere licensing because the vSAN Witness Appliance is provided by VMware with its own embedded license and does not require an additional separate vSphere license. This makes it a more cost-effective solution compared to using a physical witness, which would need its own vSphere license.

Question 5 of 100
A storage administrator discovers vSAN is rebalancing components across a cluster randomly and faces degraded performance on the applications.
What should be done to avoid these issues?
Answer

Suggested Answer

The suggested answer is C.

To avoid issues with vSAN rebalancing components randomly and causing degraded performance on the applications, it is essential to keep the total storage consumption below 70 percent. This practice ensures there is enough free space for maintenance tasks, resynchronization after interruptions, and overall data balance, which helps in minimizing automatic rebalancing events.
