Explanation

HSRP Preemption Configuration Explanation

Based on the exhibit (which typically shows R1 configured with a higher HSRP priority and preemption enabled, while R2 has a lower priority without preemption), R1 wins the HSRP election due to its higher priority and immediately becomes the active router (A), making option B incorrect. Option D is correct because R2 lacks the standby preempt command, meaning if R1 fails and R2 takes over as active, R2 will remain active even after R1 recovers - without preemption, a router cannot "reclaim" the active role. Option C is wrong because it incorrectly describes R1's behavior when R2 fails (R1 simply becomes active, not reverting), and option E is the opposite of D - it incorrectly suggests R1 would reclaim the active role, which only happens if preemption is configured on R1.

Memory Tip: Think of preemption as a "takeback" switch - if a router has standby preempt, it will fight to reclaim the active role when it returns. If no preempt is configured, the recovering router humbly stays as standby, letting whoever is currently active keep the role. Always check which router has preempt to determine post-failure behavior.
