GLBP is configured on a network as its first-hop redundancy protocol. The GLBP group has three members. For some reason, the AVG on the group becomes unavailable. How would the routers in the GLBP group handle the situation?

An election process will take place, and since there are more than two members in the group, the member with the highest GLBP priority will take over as the new AVG. Highest IP address will be the tie-breaker if the members have the same priority

The new AVG will be elected randomly because there are more than two members in the group

An election process will take place, and, since there are more than three members in the group, the only parameter to be used in selecting the new AVG is the highest IP address

An election process will take place, the member with the highest GLBP priority will take over as the new AVG. If they have the same priority, the member with the highest Virtual MAC address will take over as the new AVG

Explanation

If an AVG fails, an election process will take place. Because there are three members in the GLBP group, first, the member with the highest priority will be elected as the new AVG, and, if they have the same priority, the member with the highest IP address will be elected. If there are only two members, then that backup gateway will take over immediately. The virtual MAC address is not used as a tie-breaker and the election of AVG is not done randomly.
