If a gateway fails in a network using First Hop Redundancy, hosts should still be able to reach their default gateway.

First Hop Redundancy Protocols keep the first-hop gateway highly available by sharing a virtual gateway address across multiple routers. The hosts on the network use this virtual IP as their default gateway, and there’s a virtual MAC associated with that IP. One router acts as the active gateway, and others are ready to take over as backups. If the active router fails, a backup becomes active and starts answering ARP requests for the virtual IP, effectively taking over the gateway role without the hosts needing any reconfiguration. Traffic continues to be sent to the same gateway IP, so reachability to the default gateway is preserved, though a brief failover moment may occur. This is the intended behavior of FHRP, so the statement is true.
