The correct answer is C. Both resource pools no longer exist and all virtual machines that resided in the resource pools. Disabling DRS on a cluster permanently destroys all resource pools; re-enabling DRS does not restore them, leaving the cluster with no resource pool configuration.
Question
A cluster with two resource pools named RP-PROD and RP-DEV is configured based on custom requirements. A vSphere administrator temporarily disables DRS for this cluster. Upon re-enabling DRS, how would the resource pool configuration have changed?
Options
- ABoth resource pools still exist, but their shares have been reverted to the default share values.
- BNothing. Everything has stayed the same.
- CBoth resource pools no longer exist and all virtual machines that resided in the resource pools
- DBoth resource pools exist, but all virtual machines that resided in the resource pools now

Why each option
Disabling DRS on a cluster permanently destroys all resource pools; re-enabling DRS does not restore them, leaving the cluster with no resource pool configuration.
Share values are irrelevant because the resource pools themselves are fully destroyed when DRS is disabled, not simply reset to default values.
The configuration does not remain intact; disabling DRS is destructive to resource pool definitions and the prior state is not preserved or restored upon re-enabling.
vSphere resource pools are a construct tied to the DRS scheduler and are automatically deleted when DRS is disabled on a cluster. VMs that resided in those pools are moved up to the cluster root inventory, and re-enabling DRS starts with an empty resource pool hierarchy - RP-PROD and RP-DEV are permanently gone.
Resource pools do not persist in any form after DRS is disabled; they are not retained with reassigned VMs or otherwise recoverable by re-enabling DRS.
Concept tested: DRS resource pool behavior when DRS is toggled off and on
