Which has a master router and one or more backup routers. The master router has the highest priority.

• A. HSRP
• B. RIP
• C. VRRP
• D. GLBP

Answer: (C)

VRRP is a gateway redundancy protocol that elects a single master router to forward traffic for a virtual IP, with one or more backup routers standing by. Each router in the group has a priority value, and the router with the highest priority becomes the master. If the master fails, the next-highest priority backup takes over, ensuring continuous access for hosts using the virtual gateway. This behavior matches the description of having a master router with the highest priority and one or more backups. GLBP focuses on load balancing among gateways, HSRP is a Cisco variant with similar master/ standby dynamics, and RIP is a routing protocol, not a redundancy mechanism.
