VMware vSphere 7.x Advanced Design (VCAP-DCV Design 2021) — Question 24

A customer is deploying a new cluster and wants to be able to patch and update two hosts in parallel. The cluster must be able to maintain N+1 resiliency across the remaining hosts while patching activities are performed. The current expected utilization of the platform requires a minimum of two hosts to support all of the virtual machines.
What is the minimum number of hosts the customer will require in the cluster in order to meet the required resiliency level?

Answer options

Correct answer: A

Explanation

To maintain N+1 resiliency while patching two hosts, the cluster must have enough hosts to ensure that at least one host is available for every host being patched. Therefore, if two hosts are being updated, at least three must remain operational. Adding the minimum of two hosts required for utilization leads to a total of five hosts needed for the cluster. The other options do not meet this requirement.
