    VRRP determines the roles of routers (master or backup) in a virtual router based on their priorities.
  2. B
    If a backup router works in non-preemption mode and has a higher priority than the masterrouter, it will become the master router unless the master router fails.
  3. C
    After a backup router in preemption mode receives a VRRP packet from the master router, it compares its priority with the priority carried in the VRRP packet. If its priority is higher than the priority of the master router, it preempts to be the master router; if not, it remains in the backup state.
  4. D
    If two routers competing for the master router have the same priority, the router with a higher interface IP address becomes the master router.

  3. C
    Hosts on a network can communication with a virtual router without knowing any information about physical routers on the network.
  4. D
    A virtual router consists of a master router and several backup routers. The master router forwards packets. When the master router fails, a backup router
