   A network administrator is implementing GLBP on a LAN segment with two routers. The administrator wants to ensure that both routers forward traffic for the same virtual IP address. How does GLBP achieve this?

   • AIt assigns a unique virtual MAC address to each router and answers ARP requests with different virtual MACs.
   • BIt uses the physical MAC address of each router and relies on the hosts to load balance.
   • CIt configures both routers with the same physical MAC address and uses equal-cost routing.
   • DIt uses a single virtual MAC address that both routers share, and the active router forwards all traffic.

   A network administrator is implementing GLBP on a LAN segment with three routers. The administrator wants to ensure that if one router fails, the remaining two routers continue to forward traffic and that the load is redistributed. What must be configured?

   • AConfigure multiple GLBP groups and assign each router to a different group.
   • BEnable preemption on all routers and set different priorities.
   • CUse HSRP instead of GLBP to ensure load redistribution.
   • DConfigure GLBP with a single virtual IP address and let the AVG manage virtual MAC assignments.

   In an HSRP group, what is the role of the router with the highest priority value?

   • AIt becomes the backup router and only forwards traffic if the active router fails
   • BIt becomes the active router and forwards traffic for the virtual IP address
   • CIt becomes the standby router and monitors the active router for failures
   • DIt becomes the virtual router and does not forward any traffic

   A network administrator is designing a LAN segment where end hosts use a single default gateway IP address. The administrator wants to ensure that if the router currently serving as the default gateway fails, another router can take over without requiring any configuration changes on the hosts. What is the primary purpose of implementing a first hop redundancy protocol (FHRP) in this scenario?

   • ATo provide a secondary IP address on each router so that hosts can manually switch to a backup gateway
   • BTo enable routers to exchange routing tables so that they can learn the best path to remote networks
   • CTo provide a virtual IP address that is shared among routers so that hosts always have a reachable default gateway
   • DTo load balance traffic between multiple routers by assigning each host a different default gateway IP address

   An administrator is configuring HSRP and wants to ensure that if the active router's uplink to the ISP fails, the standby router will take over as active. What should the administrator configure?

   • ASet the HSRP hold timer to a very low value on the standby router.
   • BConfigure a static route on the standby router to the ISP.
   • CEnable HSRP preemption on both routers.
   • DConfigure HSRP object tracking on the uplink interface and reduce the priority of the active router when the uplink goes down.
