Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 969

A network engineer must configure the VTY lines on a router to achieve these results:

• Remote access should be permitted for all feasible protocols.
• Only a password should be required for device authentication.
• All idle EXEC sessions must be terminated in 60 minutes.

Which configuration should be applied?

Answer options

• A. line vty 0 15 password Cisco123 transport input ssh exec-timeout 60
• B. line vty 0 15 login password Cisco123 transport input all absolute-timeout 60
• C. line vty 0 15 password Cisco123 transport input all exec-timeout 60
• D. line vty 0 15 transport input telnet ssh rlogin login local absolute-timeout 60

Correct answer: C

Explanation

Option C is correct because it allows all protocols for remote access, requires only a password for authentication, and sets the idle timeout for EXEC sessions to 60 minutes. Option A restricts access to SSH only, while Option B uses 'absolute-timeout' instead of 'exec-timeout', which is not the correct command for this scenario. Option D also incorrectly uses 'absolute-timeout' and requires local login instead of just a password.
