Question

In regards to HA, if two hosts have datastore access, how is the new master selected?

A) Based on the host with the highest CPU utilization.
B) Based on the host with the highest memory utilization.
C) Based on the host with the highest network throughput.
D) Based on the host with the lowest UUID (Universally Unique Identifier).

Answer 1

In VMware HA clusters, the new master host is chosen based on the host with the lowest UUID, ensuring a consistent selection process.

Step-by-step explanation:

In VMware High Availability (HA) setups, when there is a need to select a new master among hosts that have datastore access, the new master is typically selected based on a specific attribute. The correct option from the provided choices is:

• D) Based on the host with the lowest UUID (Universally Unique Identifier).

The HA master host is responsible for monitoring the state of other hosts in the HA cluster and for managing the process of restart for VMs in case of host failures. The use of the UUID ensures a consistent and straightforward selection process, which avoids the fluctuating metrics such as CPU.
