FC0-U71 Practice Question: Refer to the exhibit

Exhibit

 no shutdown

Refer to the exhibit. What is the purpose of the 'no shutdown' command in this router configuration?

⚠ Common exam trap

CompTIA often tests the misconception that 'no shutdown' is used to remove a configuration or reset an interface, when in fact it specifically toggles the administrative state from disabled to enabled.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

Enable the interface

The 'no shutdown' command is used in Cisco IOS to administratively bring an interface from the 'administratively down' state to an operational 'up/up' state. By default, many router interfaces are placed in a shutdown state upon initial configuration, and issuing 'no shutdown' enables the interface to send and receive traffic.
