Which protocol is described as a secure connection to transfer information and uses certificates to authenticate the server?

• A. SSH
• B. PGP
• C. HTTPS
• D. SSL

Answer: (C)

HTTPS is HTTP over TLS, which provides a secure way to transfer information by encrypting the data in transit and authenticating the server with a digital certificate. During the TLS handshake, the server presents a certificate issued by a trusted authority, the client verifies it, and then a session key is established to encrypt all subsequent data. This combination of confidentiality, integrity, and server authentication is what makes HTTPS the described protocol. The other options cover different secure mechanisms (for example, SSH for secure remote access and PGP for email encryption), and while SSL is related, modern secure web traffic uses TLS under the HTTPS umbrella.
