Final answer:
If Router A sees the distance between Network X and Router B with the next hop, it means that Router A and Router B are directly connected.
Step-by-step explanation:
If Router A sees the distance between Network X and Router B even with the next hop to travel from Router A to Router B, it means that Router A and Router B are directly connected. In networking, the term 'next hop' refers to the next router in the path to reach the destination network. When Router A can see the distance to Router B along with the next hop, it indicates that the two routers are adjacent to each other in the network topology.
