Configuration Processes and the Configuration File
Cisco requires that CCNAs master the process of changing and manipulating the configuration
files in the IOS. This includes initially setting up an IOS device, handling ongoing
configuration, and moving configuration files.
As mentioned in Chapter 1, "All About the Cisco Certified Network Associate Certification"
configuration mode is another mode for the Cisco CLI. Changing the configuration of the router
by typing various configuration commands is the purpose of configuration mode. Figure 2-6
illustrates the relationships among configuration mode, user EXEC mode, and priviledged
EXEC mode.
