B. show sessions
C. show interfaces
D. show standby
Which two outcomes are predictable behaviors for HSRP? (Choose two)
A. The two routers share a virtual IP address that is used as the default gateway for devices on the LAN
B. The two routers negotiate one router as the active router and the other as the standby router
C. Each router has a different IP address both routers act as the default gateway on the LAN, and traffic is load balanced between them
D. The two routers synchronize configurations to provide consistent packet forwarding
E. The two routed share the same IP address, and default gateway traffic is load-balanced between them
How does HSRP provide first hop redundancy?
A. It load-balances traffic by assigning the same metric value to more than one route to the same destination in the IP routing table
B. It load-balances Layer 2 traffic along the path by flooding traffic out all interfaces configured with the same VLAN
C. It forwards multiple packets to the same destination over different routed links and data path
D. It uses a shared virtual MAC and a virtual IP address to a group of routers that serve as the default gateway for hosts on a LAN
What is the primary purpose of a First Hop Redundancy Protocol?
A. It allows directly connected neighbors to share configuration information
B. It allows a router to use bridge priorities to create multiple loop-free paths to a single destination
C. It reduces routing failures by allowing Layer 3 load balancing between OSPF neighbors that have the same link metric
D. It reduces routing failures by allowing more than one router to represent itself, as the default gateway of a network
When the active router in an HSRP group fails, what router assumes the role and forwards packets?
A. listening
B. backup
C. forwarding
D. standby

33. Refer to Exhibit. How does SW2 interact with other switches in this VTP domain?
