If two routers connected to the same Ethernet are configured to run HSRP (Hot Standby Router Protocol) in the same group number, which router’s MAC address will be associated with the virtual IP address?

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:
