VCP550 · Question #71

What two requirements must be met to create a fully automated Distributed Resource Scheduler (DRS) cluster? (Choose two.)

The correct answer is A. Shared storage D. vMotion. A fully automated DRS cluster requires shared storage so any host can access VM disk files, and vMotion so running VMs can be live-migrated between hosts for load balancing.

Why each option

A fully automated DRS cluster requires shared storage so any host can access VM disk files, and vMotion so running VMs can be live-migrated between hosts for load balancing.

AShared storageCorrect

Shared storage is mandatory because DRS must be able to run any VM on any host in the cluster; without a shared datastore, a destination host cannot access the VM's disk files and vMotion cannot complete the migration.

BHosts with identical processor features

Identical processor features are not a hard requirement for DRS; Enhanced vMotion Compatibility (EVC) can bridge mixed CPU generations, and DRS itself does not mandate homogeneous processors.

CStorage vMotion

Storage vMotion enables live migration of VM disk files between datastores and is a prerequisite for Storage DRS, not Compute DRS; a standard fully automated DRS cluster does not require it.

DvMotionCorrect

vMotion is the core technology DRS uses to migrate running VMs between hosts to balance CPU and memory utilization; without vMotion, DRS has no mechanism to rebalance workloads and cannot function in fully automated mode.
