Cisco CCNA (200-301)Network FundamentalsEasy
A network administrator is configuring a new Cisco switch using the console port. After successfully logging in, which command should they use to enter global configuration mode?
- Aconfigure interface
- Benable config
- Cconfigure terminal
- Dterminal configure
Show answer & explanationAnswer & explanation
Correct answer: C. configure terminal
The 'configure terminal' command is used in Cisco IOS to transition from privileged EXEC mode to global configuration mode, allowing for system-wide configuration changes.
Why the other options are wrong
- A. 'configure interface' is an invalid command; interface-specific configuration is done within interface configuration mode.
- B. 'enable config' is an invalid command; 'enable' is used to enter privileged EXEC mode.
- D. 'terminal configure' is an invalid command; the correct syntax is 'configure terminal'.
Cisco IOS Global Configuration Mode
Global configuration mode is a primary configuration mode in Cisco IOS where system-wide parameters like hostname, routing protocols, and user accounts are set.
- Accessed from privileged EXEC mode.
- Indicated by the prompt `(config)#`.
- Allows for broad, system-level changes.
Memory trick: Every user needs an interface, but global changes need a terminal.
