Certified Network Defender (CND) — Question 4

In which of the following conditions does the system enter ROM monitor mode? Each correct answer represents a complete solution. Choose all that apply.

Answer options

• A. The router does not have a configuration file.
• B. There is a need to set operating parameters.
• C. The user interrupts the boot sequence.
• D. The router does not find a valid operating system image.

Correct answer: D, C

Explanation

The system enters ROM monitor mode when it cannot find a valid operating system image (D) or when the user interrupts the boot process (C). Options A and B are not correct because a missing configuration file does not directly lead to ROM monitor mode, nor does the need to set parameters trigger this mode.
