Why each option
When manual resume is enabled for a pool member, if its health check fails and then passes, the member remains in an Offline (Disabled) state, requiring manual intervention to restore service.
With manual resume enabled, a pool member that fails its health monitor is marked as Offline (Disabled). It will stay in this disabled state even if subsequent health checks pass, and requires a manual administrative action to be re-enabled and become available again.
If manual resume is enabled, a failed pool member would be disabled, not merely enabled in an offline state, as 'enabled' implies it could be brought online automatically.
The pool member's status would not be 'Available' after a health check failure, regardless of manual resume being enabled, because 'Available' signifies it is ready to receive traffic.
The pool member cannot be 'Available (Enabled)' if it first fails a health check and manual resume is enabled, as manual resume explicitly prevents automatic re-enabling.
