Which entry from the routing table indicates a host route?

• A. L 192.168.1.1/32 is directly connected, F0/1
• B. O 192.168.1.0/24 [110/2] via 10.1.1.3, F0/0
• C. C 192.168.1.0/30 is directly connected, F0/0
• D. S 192.168.1.0/24 [5/0] via 10.1.2.3

Answer: (A)

A host route is a single-host entry using a /32 prefix, typically shown with the local route code (L). This indicates the router’s own address on an interface and tells the router how to deliver frames addressed to that specific IP. The line with L 192.168.1.1/32 is exactly that: it points to the router’s own IP 192.168.1.1 on interface F0/1, meaning packets destined for 192.168.1.1 are consumed locally by the router, not forwarded. Other entries show networks rather than a single host. A /24 or /30 prefix represents a network, not a specific host, and the codes (C for directly connected network, O for OSPF-learned, S for static) indicate different routing sources or types of routes. Hence, the /32 host route is the correct indicator of a host route.
