CCNA Routing and Switching (legacy) — Question 35

What can be done to secure the virtual terminal interfaces on a router? (Choose two.)

Answer options

• A. Administratively shut down the interface.
• B. Physically secure the interface.
• C. Create an access list and apply to the virtual terminal interfaces with the access-group command.
• D. Configure a virtual terminal password and login process.
• E. Enter an access list and apply it to the virtual terminal interfaces using the access-class command.

Correct answer: D, E

Explanation

The correct options are D and E because configuring a virtual terminal password and a login process (D) ensures that only authorized users can access the interface, while applying an access list with the access-class command (E) restricts access based on specified criteria. Options A and B do not effectively secure the virtual terminal interfaces, as shutting down the interface (A) is not a practical security measure, and physically securing the interface (B) is not applicable for virtual terminals.
