Alcatel-Lucent NRS I Composite Exam — Question 8

You are configuring your Alcatel-Lucent 7750SR Service Router from the Command Line Interface (CLI), and after entering a lengthy command, wish to return directly to the ROOT context. Which control command allows you to do this quickly?

Answer options

• A. Ctrl-z
• B. Ctrl-c
• C. Esc
• D. Shift-Page Down

Correct answer: A

Explanation

The correct answer is Ctrl-z, as it is specifically designed to exit the current context and return to the ROOT context in the CLI. Ctrl-c is used to cancel a command in progress, while Esc and Shift-Page Down do not provide the functionality needed to return to the ROOT context.
