Correct answers: A, B, C
Explanation
To effectively verify and troubleshoot the interface status, you need to view the interface summary with 'show ip interface brief,' use command help and auto-complete for correct syntax, and enter privileged EXEC mode to gain access to advanced commands. Skipping to configuration mode directly from user EXEC mode is not possible, making option 4 incorrect.
- A. Correct.
The 'show ip interface brief' command provides a quick summary of all interfaces, their statuses, and IP address information, which is essential for troubleshooting.
- B. Correct.
Using '?' after a partial command provides a list of available commands or options, helping to ensure the correct syntax when troubleshooting.
- C. Correct.
Entering privileged EXEC mode using the 'enable' command grants access to additional diagnostic and configuration commands needed for troubleshooting.
- D. Incorrect.
You cannot directly enter 'configure terminal' from user EXEC mode. You must first enter privileged EXEC mode using the 'enable' command.
