A network engineer is designing a campus network with high availability for critical services. Which Cisco technology enables traffic to be forwarded to an alternate next hop in the event of a first-hop router failure, without requiring any configuration changes on the hosts?
Trap 1: Static default route with a floating static
Floating static routes require host configuration changes and are not transparent to hosts.
Trap 2: GLBP
GLBP provides load balancing along with redundancy, but HSRP is more commonly used for simple failover.
Trap 3: VRRP
VRRP is a standard protocol similar to HSRP but not Cisco proprietary.
- A
Static default route with a floating static
Why wrong: Floating static routes require host configuration changes and are not transparent to hosts.
- B

Why wrong: GLBP provides load balancing along with redundancy, but HSRP is more commonly used for simple failover.
- C
VRRP
Why wrong: VRRP is a standard protocol similar to HSRP but not Cisco proprietary.
- D
HSRP
HSRP is a Cisco proprietary FHRP that provides transparent failover without host configuration changes.
