A company's network design requires that there should be no single point of failure for the default gateway used by hosts on a subnet. Which protocol would be best suited to ensure that if the active gateway fails, another router will immediately take over the role of the default gateway without significant disruption to network traffic?
Configure Routing Information Protocol (RIP) on the routers
Set a static route on each host to a secondary gateway
Configure Virtual Router Redundancy Protocol (VRRP) on the routers
Enable Spanning Tree Protocol (STP) on participating switches
