An organization has configured Distributed Power Management (DPM) on a vSphere 6 cluster. The organization wants to be alerted when an ESXi host has been powered down by DPM. Which two options…
The correct answer is B. DrsEnteredStandbyModeEvent C. Event-based. DPM uses DRS infrastructure to power ESXi hosts on and off, and alerting on a completed standby entry requires an event-based alarm tied to the correct past-tense event name.

Why each option
DPM uses DRS infrastructure to power ESXi hosts on and off, and alerting on a completed standby entry requires an event-based alarm tied to the correct past-tense event name.
DrsEnteringStandbyModeEvent fires while the host is in the process of entering standby (present progressive), not after the power-down is complete, so it does not satisfy the requirement to alert when the host has been powered down.
DrsEnteredStandbyModeEvent is the event fired after a host has fully entered standby mode (past tense, action completed), making it the correct event name to trigger an alert that DPM has powered down the host.
An event-based alarm is required because the desired notification is triggered by a discrete, one-time occurrence (the host entering standby), not by a continuously monitored metric or state condition.
A condition-based alarm monitors an ongoing metric or state threshold (such as CPU usage remaining above a value), which is inappropriate for detecting a discrete event like a host being powered down by DPM.
