Since Auto Failback is enabled, BIGIP-D will come out of standby and become active once BIGIP-B reboots.

When BIGIP-B goes down:

BIGIP-D is skipped because it is Forced Offline/Standby.
The next available device in the HA order is BIGIP-C, which becomes active.

When BIGIP-B finishes rebooting:

Because auto failback is enabled, the traffic group automatically moves back to the highest-priority available device according to the HA order.
BIGIP-D is still forced to standby, so it is not eligible.
The next highest-priority available device is BIGIP-B.
