Refer to the Exhibit. An administrator is reviewing a vSphere Distributed Resource Scheduler (DRS) enabled Cluster and observes unexpected behavior as shown in the Exhibit.
What are three potential causes of the cluster imbalance? (Choose three.)
A. A local device is mounted to one or more virtual machines.
B. DRS rules prevent virtual machines from being moved.
C. vMotion is not configured and enabled.
D. There are insufficient cluster resources to perform the migration.
E. DRS has been configured for a conservative migration threshold.

Not C, because the picture shows that vMotion is up and running
Not D, because the picture shows that there are clearly enough host memory and host CPU resources.
The link also states:
“The migration threshold is too high.
A higher threshold makes the cluster a more likely candidate for load imbalance.”
which makes ‘E’ valid

A,B,C and E are mentioned as possible causes, but in the exhibit we can see that vMotion migrations has occured (124 of them), which should rule out C.
