A network engineer must configure a switch to allow remote access for all feasible protocols. Only a password must be requested for device authentication and all idle sessions must be terminated in 30
The correct answer is A. line vty 0 15. Remote access (VTY) configuration requires enabling all feasible transport protocols, setting a local password for authentication, and configuring an idle session timeout.

Why each option
Remote access (VTY) configuration requires enabling all feasible transport protocols, setting a local password for authentication, and configuring an idle session timeout.
This configuration correctly enters VTY line configuration, enables all transport protocols (`transport input all`), sets a password for authentication (`password cisco` and `login`), and configures the idle session timeout to 30 minutes (`exec-timeout 30 0`).
While `transport input all` and `exec-timeout 30 0` are correct, `login local` requires a local username database for authentication, which contradicts the requirement for 'only a password' used directly on the line.
Concept tested: VTY line configuration (remote access, authentication, timeout)
