You work as a network engineer at domain .com. Study the topology exhibit carefully. Routers domain .com E and domain .com F are configured for HSRP (Hot Standby Routing Protocol). domain .com E has a priority of 100, while domain .com F has a priority of 50. At one point, when domain .com E is the active router, it fails, and domain .com F takes over as the active router. A few minutes later, domain .com E returns to service. What happens? Exhibit:

A.
domain .com F will remain the active router; there is no way for domain .com E to become the active router again unless domain .com F fails.

B.
domain .com E and domain .com F will negotiate which router should be active based on their IP addresses.

C.
domain .com E will always take over the active role; there is no way for domain .com F to remain active once another router with a higher priority is on the network.

D.
domain .com E will become the active router, if it is configured to preempt.
domain .com E. domain .com F will remain the active router because having a lower priority is better.
