A Distributed Resource Scheduler (DRS) cluster is displaying a message that recommends the
migration of virtual machines, even though the cluster is currently balanced.
What is the likely reason for this?
A.
The DRS cluster does not satisfy the resource pool reservations.
B.
The DRS cluster is not configured with shared storage.
C.
The DRS cluster is in a critical state.
D.
The DRS cluster contains hosts with CPU compatibility issues.
Explanation:
“A”
Why ‘A’ ? Not obvious at all…
I think is “A” but couldn’t find the best answer for this, but this is a begin
Virtual Machine Migration
When a cluster enabled for DRS becomes unbalanced, DRS makes recommendations or
migrates virtual machines depending on the automation level:
• If the cluster is manual or partially automated, VirtualCenter does not take automatic
actions to balance resources. Instead, the Summary page indicates that migration
recommendations are available and the Migration page displays recommendations for the
most efficient use of resources across the cluster.
