2V0-620 · Question #166
Which two statements are correct when turning off a Distributed Resource Scheduler (DRS) Cluster? (Choose two.)
The correct answer is B. The resource pool hierarchy of the DRS cluster is removed. C. The affinity settings of the DRS cluster are removed and not maintained when DRS is re-enabled. When DRS is disabled on a cluster, the resource pool hierarchy is removed and affinity rules are also discarded and will not be restored if DRS is later re-enabled.

Why each option
When DRS is disabled on a cluster, the resource pool hierarchy is removed and affinity rules are also discarded and will not be restored if DRS is later re-enabled.
The resource pool hierarchy is not maintained when DRS is disabled; it is destroyed because resource pools depend on DRS being active to function.
Disabling DRS removes the resource pool hierarchy because resource pools are a DRS construct; without DRS active, vSphere cannot maintain or enforce the pool configuration, so it is deleted.
Affinity and anti-affinity rules are also DRS-specific settings that are removed when DRS is turned off, and they are not persisted or automatically restored if DRS is re-enabled later, requiring manual reconfiguration.
Affinity settings are not maintained or preserved through a DRS disable/re-enable cycle; they must be manually recreated after DRS is turned back on.
