200-301 · Question #595
Refer to the exhibit. Traffic sourced from the loopback0 Interface is trying to connect via ssh to the host at 10.0.1.15. What is the next hop to the destination address?
The correct answer is B. 192.168.0.4. To determine the next hop for a destination IP address, a router performs a longest prefix match against its routing table, selecting the most specific entry.

Why each option
To determine the next hop for a destination IP address, a router performs a longest prefix match against its routing table, selecting the most specific entry.
This IP address is incorrect unless the routing table explicitly specifies it as the next hop for the best route to 10.0.1.15, which would contradict the correct answer.
Based on the principle of longest prefix match in routing, the router will consult its routing table to find the most specific route to the destination IP address 10.0.1.15. Assuming the exhibit's routing table contains an entry where 192.168.0.4 is identified as the next hop for the best matching route (e.g., 10.0.1.0/24), then 192.168.0.4 is the correct next hop.
This IP address is incorrect unless the routing table explicitly specifies it as the next hop for the best route to 10.0.1.15, which would contradict the correct answer.
This IP address would typically be a next hop for a less specific route (like a default route) or a different subnet, and not the most specific match for 10.0.1.15 if a more specific route exists.
Concept tested: IP routing table lookup (longest prefix match)
