Exam 200-301 topic 1 question 972 discussion

To allow administrators to authenticate via Telnet directly to global configuration mode using a local username and password, the switch must be configured with a local username and corresponding password, and the VTY lines must be set to use local login credentials. Additionally, to ensure the user has the proper level of privilege to enter global configuration mode directly, the username should be created with the highest privilege level (15). Based on these requirements, the additional configuration that must be applied is: B. R1(config)#username admin privilege 15 secret p@ss1234 R1(config)#line vty 0 4 R1(config-line)#login local This configuration sets up a local user with full privileges and configures the VTY lines to require local username and password authentication for Telnet access. Note that there's a typographical error in the command R1(config-if)#line vty 0 4 -; it should be R1(config)#line vty 0 4, as line configuration is not done in interface configuration mode but directly in global configuration mode.

If i remember correctly, telnet is enabled by default, so we don't need the 'transport intput telnet'

'to authenticate directly to global configuration mode via Telnet using a local username and password' so answer 'B'

I've tries option B and it works, the question said "allow administrators to authenticate directly to global configuration mode", so command "privilege 15" must required.

The transport is only implied in answer A. It is not the best configuration but it may work.
