Nokia Certified Network Associate (NCNA) — Question 30

You are configuring your Nokia 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 A (Ctrl-z), which is used to exit to the ROOT context from any command level in the CLI. Option B (Ctrl-c) interrupts the current command without returning to the ROOT context, while option C (Esc) does not have the function to return to ROOT, and option D (Shift-Page Down) is not a command used for navigation in the CLI.
