An administrator must enable Telnet access to Router X using the router username and password database for authentication. Which configuration should be applied?
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
It's D, but the answer is not complete. Telnet would have be enabled on newer code like 17.1. For older gear it was enabled out of the box.
CAT9-UADP_2(config-line)#login local ?
<cr> <cr>
CAT9-UADP_2(config-line)#login local
CAT9-UADP_2(config-line)#do sh run | i transport input (show defaults)
transport input ssh
transport input ssh
CAT9-UADP_2(config-line)#
CAT9-UADP_2(config-line)#transport input ?
all All protocols
none No protocols
ssh TCP/IP SSH protocol
telnet TCP/IP Telnet protocol

Most search returns show that Telnet is on by default with Cisco. So, D would be the nearest to true answer.
However, in CML with newer code, no transport is set:
R20#more system:default-running-config | s transport
mode transport
transport input none <------------
R20#sh ver | s Version
Cisco IOS Software, IOSv Software (VIOS-ADVENTERPRISEK9-M), Version 15.9(3)M8, RELEASE SOFTWARE (fc1)

login local → username + password
