Answer: A, D

Explanation:

The configuration shows that R1 and R2 are configured for HSRP (Hot Standby Router Protocol). R1 has a higher priority (120) than R2 (110), so R1 becomes the active router. If R1 goes down, R2 will become active because of its lower priority but will not revert back to standby when R1 comes back online due to preemption not being configured.
