2V0-620 · Question #160

Which two events happen when Distributed Resource Scheduler (DRS) is disabled? (Choose two.)

The correct answer is B. The cluster's resource pool hierarchy and affinity rules are not re-established when DRS is turned C. The cluster's resource pools are removed from the cluster. Disabling DRS removes all resource pools from the cluster, and those resource pools along with their hierarchy and affinity rules are not automatically restored when DRS is re-enabled.

Why each option

Disabling DRS removes all resource pools from the cluster, and those resource pools along with their hierarchy and affinity rules are not automatically restored when DRS is re-enabled.

AThe cluster's resource pool heirarchy and affinity rules are re-established when DRS is turned

This statement is incorrect because the resource pool hierarchy and affinity rules are NOT re-established when DRS is turned back on - they are permanently lost at the time DRS is disabled.

BThe cluster's resource pool hierarchy and affinity rules are not re-established when DRS is turnedCorrect

When DRS is disabled, the resource pool hierarchy, VM-to-resource-pool assignments, and affinity rules are permanently discarded and will not be automatically re-established if DRS is turned back on - administrators must recreate them manually.

CThe cluster's resource pools are removed from the cluster.Correct

All resource pools defined within the DRS cluster are deleted from the cluster when DRS is disabled, because resource pools are a DRS construct and cannot exist on a cluster without DRS enabled.

DThe cluster's resource pools are removed from the cluster and assigned to the hosts.

Resource pools are not re-assigned to individual hosts when DRS is disabled - they are simply removed entirely, as resource pools are a cluster-level construct that has no per-host equivalent.

Concept tested: DRS disable behavior on resource pools and affinity rules
