Question 298

Which of the following statements about VRRP are true? (Choose three.)

VRRP determines the roles of routers (master or backup) in a virtual router based on their priorities.

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.

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 bethe master router; if not, it remains in the backup state.

If two routers competing for the master router have the same priority, the router with a higher interface IP address becomes the master router.

Question 299

Which of the following statements about VRRP are true? (Choose three.)

VRRP is a redundancy protocol designed for a multicast- or broadcast-capable LAN such as the Ethernet. VRRP ensures that traffic is switched to another router when the next-hop router for a host on the LAN fails. This guarantees thereliability and non-stop forwarding of services.

In VRRP, two virtual router ID and a virtual IP address need to be configured on a router to generate a virtual MAC address. A virtual router is formed.

Hosts on a network can communication with a virtual router without knowing any information about physical routers on the network.

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 takes over as the master router.
