Cisco CCNA (200-301)Network FundamentalsEasy
A network engineer is configuring a new Cisco router. After connecting to the console port, they see a prompt like `Router>`. To access configuration commands for interfaces, routing protocols, and other global settings, what is the next command mode the engineer must enter?
- AInterface Configuration Mode
- BGlobal Configuration Mode
- CPrivileged EXEC Mode
- DLine Configuration Mode
Show answer & explanationAnswer & explanation
Correct answer: C. Privileged EXEC Mode
The `Router>` prompt indicates User EXEC mode. To access configuration commands, the engineer must first enter Privileged EXEC mode using the `enable` command, which changes the prompt to `Router#`.
Why the other options are wrong
- A. Interface Configuration Mode is entered from Global Configuration Mode to configure specific interfaces.
- B. Global Configuration Mode is entered from Privileged EXEC mode using `configure terminal`, but Privileged EXEC is the immediate next step from User EXEC.
- D. Line Configuration Mode is used to configure console, AUX, and VTY lines, not global settings or interfaces.
Cisco IOS Command Modes
Cisco IOS uses a hierarchical structure of command modes, each with specific command sets, to manage and configure network devices.
- User EXEC Mode (`>`) provides basic monitoring commands.
- Privileged EXEC Mode (`#`) allows more powerful monitoring and access to configuration modes.
- Global Configuration Mode (`(config)#`) is for device-wide settings.
- Specific configuration modes (e.g., interface, router) are entered from Global Configuration Mode.
Memory trick: User to Privileged, then Global to Specific.
