What option is the most efficient resolution to enable additional VMs to be created?

An administrator manages an AHV cluster that is dedicated to a dev/test environment. The administrator receiving complaints from users that they are unable to create new VMs on the cluster.

After the reviewing the cluster, the administrator finds that the memory resources are almost fully utilized, with many VMs over-provisioned on memory.

What option is the most efficient resolution to enable additional VMs to be created?
A . Enable Memory Overcommit on the over-provisioned VMs.
B. Enable Memory HA on the over-provisioned VMs.
C. Upgrade the nodes with additional memory DlMMs.
D. Disable HA Reservation on the cluster.

Answer: A

Explanation:

Enable Memory Overcommit on the over-provisioned VMs is the most efficient resolution to enable additional VMs to be created. Memory overcommit allows VMs to use more memory than physically available on a host by compressing and swapping memory pages to storage1. This can improve memory utilization and increase VM density on a cluster1. However, memory overcommit is not supported when HA is configured to use reserved hosts, so you may need to disable HA reservation on the cluster before enabling memory overcommit1.
