Correct answer: It provides the default gateway redundancy on a LAN using two or more routers..
Why this is the answer
VRRP (Virtual Router Redundancy Protocol) is a First Hop Redundancy Protocol (FHRP) that provides default gateway redundancy. It allows multiple routers to share a single virtual IP address and MAC address, acting as a single virtual router. If the active router fails, a standby router automatically takes over the role of the default gateway, ensuring continuous network connectivity for hosts on the LAN. Traffic load balancing is typically handled by protocols like GLBP or by configuring equal-cost multi-path (ECMP) routing, not VRRP. Preventing Layer 2 loops is the function of Spanning Tree Protocol (STP). Sharing routing table information is the role of routing protocols like OSPF or EIGRP.
