   A network engineer is implementing HSRP on a pair of routers. The engineer wants to ensure that the router with the higher priority becomes the active router and that it regains the active role after a failure and recovery. Which two configuration elements are required?

   • AIncrease the hold timer on the preferred router and set the same priority on both routers.
   • BSet the priority value and enable preemption on the preferred router.
   • CConfigure a higher virtual MAC address on the preferred router and enable preemption on the standby router.
   • DSet the hello timer to a lower value on the preferred router and disable preemption.

   Which statement accurately describes how a first hop redundancy protocol (FHRP) can provide load balancing among multiple routers on the same LAN?

   • AIt load balances by having each router forward traffic for a different protocol, such as TCP or UDP
   • BIt requires hosts to be configured with multiple default gateway IP addresses and to alternate between them
   • CIt uses a single virtual IP address but allows multiple routers to forward traffic simultaneously for different hosts
   • DIt assigns different virtual IP addresses to different groups of hosts, and each group uses a different active router

   A network engineer is troubleshooting an HSRP deployment. The two routers are in the same HSRP group, but the standby router is not taking over when the active router fails. The engineer verifies that the standby router is receiving HSRP hello messages from the active router. What is the most likely cause of the failure?

   • AThe standby router has a lower priority than the active router.
   • BThe virtual IP address is not configured on the standby router.
   • CThe hello timer is set too low on the standby router.
   • DThe standby router has preemption enabled.

   A network administrator needs to provide default gateway redundancy for a LAN segment. The requirement is that both routers should be able to forward traffic simultaneously to make use of both uplinks, rather than having one router idle. Which protocol should the administrator choose?

   • AVRRP with a single virtual router.
   • BStatic routing with equal-cost paths on the hosts.
   • CHSRP with two groups configured on the same pair of routers.
   • DGLBP with a single virtual IP address.
