  3. routing data between networks.
  4. troubleshooting.
  5. connecting one router to another.

Answer:

Correct answer: 1, 2 and 4
Explanation: By using router console port you can configure router, can set password and recover password, troubleshooting etc. So, options 1, 2 and 4 are the correct answers. But to route data between networks, you need to define routing protocol. So, option 3 is incorrect. To connect one router to another you need a physical medium. There is no use of console port. So, option 5 is incorrect.

Question No. 02
