Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 967
An administrator must enable Telnet access to Router X using the router username and password database for authentication. Which configuration should be applied?
Answer options
- A. RouterX(config)# line aux 0 - RouterX(config-line)# password cisco RouterX(config-line)# login -
- B. RouterX(config)# aaa new-model - RouterX(config)# aaa authentication login auth-list local
- C. RouterX(config)# line vty 0 4 - RouterX(config-line)# login - RouterX(config-line)# end -
- D. RouterX(config)# line vty 0 4 - RouterX(config-line)# login local RouterX(config-line)# end
Correct answer: D
Explanation
The correct answer is D because it configures the virtual terminal lines (vty) to use the local username and password for authentication, which is required for Telnet access. Option A incorrectly configures the auxiliary line, while options B and C do not specify the use of local authentication for Telnet sessions.
