An administrator is monitoring a High Availability (HA) and Distributed Resource Scheduler (DRS) enabled cluster and has noticed that virtual machines in the cluster are being migrated without user intervention. Why is this happening?

Question

Accepted Answer

A. The DRS Automation level is set to Fully Automated. The 'Fully Automated' DRS automation level causes the cluster to both place VMs on initial power-on and continuously rebalance workloads by initiating vMotion migrations automatically when imbalance exceeds the configured migration threshold, with no user intervention required.

Answer

B. The Automation level is set to Automatic. 'Automatic' is not a valid DRS automation level name; the valid levels are Manual, Partially Automated, and Fully Automated, so this is a distractor with an incorrect label.

Answer

C. The DPM Threshold is set to Aggressive. The DPM (Distributed Power Management) Threshold being set to Aggressive controls host power-on/off consolidation behavior, not VM migration between powered-on hosts.

Answer

D. The Power Management feature is configured. The Power Management (DPM) feature governs host power states to save energy, not load-balancing VM migrations across running hosts in the cluster.
