100-150 Question 251
Select 4You are troubleshooting a network issue where an interface on a Cisco device is not functioning as expected. You log in to the device and attempt to use the 'show ip interface brief' command, but you receive an error message stating 'Incomplete command'. You suspect that your current privilege level is restricting your access. What steps should you take to resolve this issue and verify the interface status?
- A
Use the '?' command to check the available commands and their syntax.
- B
Request a higher privilege level from the network administrator to access the required commands.
- C
Use the 'tab' key to auto-complete the command syntax and ensure it is entered correctly.
- D
Run the 'show interfaces status' command even at a low privilege level, as it works in all modes.
- E
Switch to privileged EXEC mode using the 'enable' command and reattempt the 'show ip interface brief' command.
Show answer and explanation
Correct answers: A, B, C, E
Explanation
The error 'Incomplete command' can occur due to incorrect syntax, insufficient privilege level, or incomplete command entry. Using the '?' command and 'tab' key helps verify and correct the syntax. If the privilege level is too low, requesting higher privileges or switching to privileged EXEC mode using the 'enable' command is necessary to access restricted commands like 'show ip interface brief'. Option 4 is incorrect because 'show interfaces status' also requires privileged access, making it inaccessible at lower privilege levels.
- A. Correct.
Using the '?' command provides guidance on available commands and their correct syntax, which can help you identify if the issue is with your command entry.
- B. Correct.
If your privilege level is too low to execute certain commands, you may need to request higher privileges from the network administrator.
- C. Correct.
Using the 'tab' key for auto-completion ensures the command syntax is correct, which can prevent errors like 'Incomplete command'.
- D. Incorrect.
The 'show interfaces status' command requires privileged EXEC mode and is not accessible at all privilege levels. Therefore, this option would not resolve the issue.
- E. Correct.
Switching to privileged EXEC mode using the 'enable' command grants access to commands like 'show ip interface brief', provided you have the correct credentials.
