CCNA Question of the Week

You examine the output of the “”show cdp neighbor”” command on Router Z and observe the following (partial output):
Device ID Local Intrfce Port ID
SwitchX fa0/0 fa0/3
RouterY s0/0/0 s0/0/2
Which statement is true regarding this scenario?

  1. Y’s s0/0/2 interface is connected to Z’s s0/0/0 interface, and Z’s fa0/0 interface is connected to X’s fa0/3 interface.
  2. Y’s s0/0/0 interface is connected to Z’s s0/0/2 interface, and Z’s fa0/3 interface is connected to X’s fa0/0 interface.
  3. Z translates X’s fa0/0 interface to its fa0/3 interface and translates Y’s s0/0/0 interface to its s0/0/2 interface.
  4. Z translates X’s fa0/3 interface to its fa0/0 interface and translates Y’s s0/0/2 interface to its s0/00 interface.

The correct answer is 1.

The “Local Intrfce” is the interface on the local device, Router Z, that is connected to the identified neighboring device. The “Port ID” is the interface on the neighboring device that is connected to the local device. Therefore, Y’s s0/0/2 interface is connected to Z’s s0/0/0 interface, and Z’s fa0/0 interface is connected to X’s fa0/3 interface.
