Routers E and F are configured for HSRP (Hot Standby Routing Protocol). E has a priority of 100,
while F has a priority of 50. At one point, when E is the active router, it fails, and F takes over as
the active router. A few minutes later, E returns to service. What happens?

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

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

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

D.
E will become the active router, if it is configured to preempt

E.
F will remain the active router because having a lower priority is better.
