Question
Refer to the exhibit. When router R1 is sending traffic to IP address 10.56.192.1, which interface or next hop address does it use to route the packet?
Options
- A10.56.0.1
- B0.0.0.0/0
- CVlan57
- D10.56.128.19
Explanation
Router R1 uses the next-hop IP address 10.56.0.1 to route traffic to 10.56.192.1, determined by finding the most specific matching route in its routing table.
Common mistakes.
- B. The 0.0.0.0/0 default route is used only when no more specific route exists in the routing table for the destination IP address.
- C. Vlan57 is an interface, but routing decisions typically involve a next-hop IP address for remote networks, or direct connection if the destination is on the same subnet.
- D. 10.56.128.19 would be a next-hop only if a more specific route for 10.56.192.1 pointed to it, or if it was part of an equally specific route but less preferred.
