Unit 1. LTM device Unit 2 becomes active as expected. The maintenance task requires the reboot of Unit 1.

has returned to standby.

Unit 1 is set with the redundancy state preference of active in high availability.

C.
A traffic group is configured with Auto Failback, and Unit 1 is the default device.
