Question 292
How does vSphere HA respond to a yellow health status on an ESXi host?
- It powers off all virtual machines immediately.
- It restarts the host operating system.
- It takes no automated HA failover action, as yellow status indicates a warning rather than a confirmed failure.
- It deletes all virtual disk files.
Correct Answer: 3
Explanation
vSphere HA relies on confirmed host failures (such as missing heartbeats or red status alerts) to trigger automated failovers. A yellow health status indicates a warning condition or degraded component but does not signal an unrecoverable host crash, so HA does not trigger failover actions.
