4. What are two characteristics of Gateway Load Balancing Protocol (GLBP) operation? (Choose two.)

• The active virtual gateway (AVG) is the backup for the AVF.

5. Refer to the exhibit. What action does the command standby 1 track Serial0/0/0 on router R1 perform?

14. Which statement is true about the gateway redundancy protocols ?

• By making use of a single virtual IP address and multiple virtual MAC addresses, HSRP provides load balancing over multiple routers (gateways). All routers in the virtual router group participate in forwarding packets.
