Question

Which of the following ports would be most likely to allow secure remote access into a system within a data center?A. UDP port 53B. UDP port 123C. TCP port 443D. TCP port 1701

Answer 1

C. TCP port 443.

Step-by-step explanation:

TCP (transmission control protocol) is a connectiod oriented protocol, that is unlike UDP (user datagram program) it needs a connection between the source and destination to be successful. Port numbers are used with ip addresses to specify packets meant for a given application.

The tcp 443 represents the HTTPs protocol, used to request and get packets from a remote and secure web server.

With this protocol and port number "TCP 443", a system can request a secure remote access to another system in a data center.
