Which condition will cause a HA/DRS cluster to display a yellow health indicator?
A.
There are insufficient resources to satisfy the cluster’s requirements.
B.
A virtual machine has failed and cannot be restarted in the cluster.
C.
Virtual machine I/O activity in the cluster has reached or exceeded a critical level.
D.
One or more hosts in the cluster has entered maintenance mode.
Explanation:
A is correct
If the cluster does not have enough resources to satisfy the reservations of all resource pools and virtual machines, but does have enough resources to satisfy the reservations of all running virtual machines, DRS continues to run and the cluster is yellow.
