I agree with the comments above. How would this make it more secure from attackers?
My understanding of an Out-of-band console router or Out-of-band access method is it’s just an alternate way of accessing a device. I figured the answer would be one of the ACLs but thinking about the question more it really seems like there isn’t enough information to make a correct choice.
Could someone help me in understanding this question and answer?
