Guys, A simple “ntp ?” CLI global config command will reveal the answer and settle all doubts.
ntp authentication-key 1 md5 141411050D 7 >> Defines the authentication key
ntp authenticate >> Enables or disables the NTP authentication feature
B seems the correct answer the way the question is phrased.
Tricky.
B
I’m leaning towards B on this one
r1(config)#ntp ?
access-group Control NTP access
authenticate Authenticate time sources
authentication-key Authentication key for trusted time sources
B is incorrect. That will simply enable NTP authentication. The correct answer is A. Read the question, you want to authenticate the time source. This has to be done with the md5 string.
Defines the authentication keys. The device does not synchronize to a time source unless the source has one of these authentication keys and the key number is specified by the ntp trusted-key number command.
Agree with ig. The answer is B.
I think “B” is correct
here, directly from the Router :
R1(config)#ntp ?
access-group Control NTP access
allow Allow processing of packets
authenticate Authenticate time sources
authentication-key Authentication key for trusted time sources
================
R1(config)#ntp authenticate ?
Answer “A” would be for entering the cmd for authentication-key
