After configuring a switch and saving the configuration to startup-config, the administrator discovers an error has been made in the configuration. Which of the following command entries removes the saved configuration and boots the switch into Setup mode?

A. erase nvram, followed by reload

B. delete nvram, followed by reload

C. erase startup-config, followed by restart

D. delete startup-config, followed by restart

Solution

A is correct. erase nvram removes the startup-config file, while reload reboots the system.

B, C, and D are incorrect. B is incorrect because delete nvram is not a CLI command. C and D are incorrect because restart is not a CLI command.
