正解:A
In the "Basic VRRP Topology" figure, if Router A, the virtual router master, fails, a selection process takes place to determine if virtual router backups B or C must take over. If Routers B and C are configured with the priorities of 101 and 100, respectively, Router B is elected to become virtual router master because it has the higher priority. If both have the same priority, the one with the higher IP address value is selected to become the virtual router master.
