Question
A network technician needs to restore the factory settings on a Cisco router. What command should they use?
A. write erase
B. erase startup-config
C. reload
D. reset factory
E. clear config
Answer
B. erase startup-config
Explanation
This command deletes the startup configuration, allowing the router to reboot with default settings.
To restore a Cisco router to factory settings, use the erase startup-config command.
- The erase startup-config command deletes the startup configuration file stored in NVRAM. This file contains all user-defined settings, including interface configurations, passwords, and routing protocols.
- After issuing the command, reload the router with the reload command. When the router restarts, it will not find a startup configuration and will prompt for initial setup, effectively returning it to factory default settings.
- This process does not erase the IOS image or other files in flash memory; it only removes the configuration, ensuring the router boots as if it were new out of the box.
erase startup-config removes all configuration settings from NVRAM, and after a reload, the router returns to its factory default state, ready for fresh configuration.
