IT Technical Interview Practice Test

Which statement about HTTP and HTTPS is true?

HTTP transmits data over TCP port 80, while HTTPS uses TCP port 443 and provides identity verification plus encryption.

HTTP and HTTPS are two web transfer protocols, with HTTPS adding security features on top of HTTP. The standard ports reflect this: HTTP uses TCP port 80, while HTTPS uses TCP port 443. HTTPS encrypts the data in transit and authenticates the server through a TLS/SSL certificate, so information remains confidential and you can be confident you’re talking to the real server. That makes the statement correct: HTTP on port 80, HTTPS on port 443, plus encryption and server identity verification. The other options mix up the ports, claim there’s no encryption, or say both use the same port, which contradicts how these protocols actually operate.

HTTP uses port 443 and HTTPS uses port 80.

HTTP never uses encryption, HTTPS never uses port 443.

HTTP and HTTPS use the same port and neither provides encryption.
