Which mode provides complete access to view the configuration files on a Cisco device?

Privileged EXEC mode is designed to allow users complete access to view the configuration files and enable features on a Cisco device. When operating in this mode, users can execute a wide range of commands that provide detailed information about the device's configuration and status, as well as settings that control the operations of the device.

In this mode, users have access to the commands necessary to display the running configuration and startup configuration files, making it a valuable tool for administrators who need to perform troubleshooting or modify settings. Users can enter Privileged EXEC mode from User EXEC mode by typing the enable command and providing the required password if one is set.

The other modes have limited capabilities. Global configuration mode allows users to set configurations but does not provide the complete access to view all files like configurations. User EXEC mode is restricted to basic commands and does not allow viewing of the detailed configuration files, while ROMMON mode is a low-level mode used primarily for system recovery and does not include typical configuration management capabilities.
