VCP-DCV vSphere Performance and Scaling Practice Question
A vSphere cluster with 3 ESXi hosts (each with 2 sockets, 8 cores per socket, hyperthreading enabled, and 256 GB RAM) runs a set of web server VMs. The cluster is configured with DRS enabled and a migration threshold of 3 (conservative). The administrator notices that one host has consistently high CPU ready time (average 15%) while the other two hosts have ready time below 2%. The host with high ready time has 10 VMs, while the others have 6 each. CPU utilization on the busy host is 80%, while on the other hosts it is 40%. What should the administrator do to improve the situation with minimal disruption?

Correct answer & explanation
✓
Increase the DRS migration threshold to a more aggressive value (e.g., 4 or 5).
The cluster is unbalanced because DRS is not migrating VMs aggressively enough. Increasing the DRS migration threshold to a more aggressive level will allow DRS to move VMs from the overloaded host to the underutilized hosts. Option D is the best immediate step. Option A would increase overhead and is not best practice. Option B would be effective but requires manual intervention and may not be the simplest. Option C would add capacity but is a longer-term solution.

- ✓
Increase the DRS migration threshold to a more aggressive value (e.g., 4 or 5).
Why this is correct
A higher threshold allows DRS to balance the cluster more aggressively, moving VMs away from the overloaded host.
