In a basic routing context, the presence of a route entry in the routing table indicates that a route is directly connected to a subnet. When a device, such as a router, is configured to connect to a particular network segment, it recognizes the networks it is directly attached to and adds those routes to its routing table. This entry typically includes the network address and subnet mask, confirming that the router has a direct link to that subnet without requiring further routing to reach it.

The other options provide scenarios that don’t accurately reflect what signifies a directly connected route. For instance, an unknown destination address does not pertain to direct connections, while a Time To Live (TTL) value of 255 pertains to packet life during transmission, not the routing table. Lastly, routes that are manually configured may or may not represent directly connected networks, as manual configuration can also pertain to static routes that point to remote networks rather than directly attached subnets. Thus, the route entry in the routing table specifically confirms direct connections.
