What characterizes a host route on a Cisco router?

• A. It uses a default gateway for routing
• B. It requires multiple destination IP addresses
• C. It uses a destination IP address of a specific device and a /32 subnet mask
• D. It automatically adjusts its subnet mask

Answer: (C)

A host route on a Cisco router is characterized by using a destination IP address that corresponds to a specific device along with a /32 subnet mask. The /32 subnet mask indicates that the route is intended for a single IP address, meaning it precisely identifies one device on the network. This specificity allows the router to direct packets destined for that particular IP address without ambiguity, effectively creating a route that is focused solely on traffic to or from that host. In contrast, a default gateway is not specific to host routes as it is used for directing traffic destined for addresses outside the local subnet. The nature of host routes means they do not require multiple destination IP addresses; they are singular and exclusive to one device. Finally, host routes do not automatically adjust their subnet masks as they are statically defined by the subnet mask provided, which remains fixed at /32 for a single host route.
