I was going through practice questions with my students yesterday and we were given the question, "An HTTPS application is secured using the SSL/TLS protocol but should use a different port for unencrypted HTTP. Which port should unencrypted HTTP use"?
We all agreed the answer was TCP/80, but that was incorrect, with the correct answer being TCP/143. I wanted to reach out the community of other instructors here so I could get a better understanding of why the answer was 143 and not 80, not just for myself but for my students as well. From reading the CompTIA A+ book, TCP/143 is HTTP associated with IMAP and reading mail messages on a server mailbox, where TCP/80 is your standard HTTP for unsecure websites. Thanks in advance for any input and clarification as to why the answer to this question is TCP/143 and not TCP/80.
