What technology enables multiple routers to appear as a single default gateway to hosts on a local network, providing continuous connectivity if one router fails?
Virtual LANs
Spanning Tree Protocol
Dynamic Host Configuration Protocol
First Hop Redundancy Protocols
First Hop Redundancy Protocols (FHRP) such as HSRP, VRRP, and GLBP allow multiple routers to share a virtual IP address as the default gateway. This ensures that if the active router fails, another router can seamlessly take over, maintaining network connectivity for hosts. The other options do not provide this functionality: Virtual LANs (VLANs) segment network traffic, Spanning Tree Protocol (STP) prevents loops in switched networks, and Dynamic Host Configuration Protocol (DHCP) assigns IP addresses to hosts.
