Question Image

Refer to the exhibit. PC A is communicating with another device at IP address 10.227.151.255. Through which router does Router Y forward the traffic?

  • A router A
  • B router B
  • C router C
  • D router D
Explanation

Router Y uses longest-prefix matching. The destination 10.227.151.255 matches both 10.0.0.0/8 and 10.128.0.0/9, but 10.128.0.0/9 is the more specific route, so it is chosen. That route points to next hop 10.224.4.3, which corresponds to router B.
