If a device does not have a startup configuration stored in

If a device does not have a startup configuration stored in NVRAM, what happens when it is booted?

A. The system boots into ROMMON.

B. The system boots directly into Privileged mode.

C. The system boots into Setup mode, prompting the user for basic configuration information.

D. Nothing. Without a startup configuration, the boot process cannot occur.

Solution

C is correct. Setup mode prompts administrators, step by step, for basic configuration settings when a startup configuration file cannot be found.

A, B, and D are incorrect. A is incorrect because the router will only boot into ROMMON when the IOS is corrupt or the configuration register is set to 2100—the presence of a startup configuration file is irrelevant to this process. B is incorrect because a Cisco device never boots directly into Privileged mode.D is incorrect because this is a false statement.
