Which abbreviation represents the protocol known as Secure Sockets Layer?

• A. SID
• B. SNMP
• C. SMTPS
• D. SSL

Answer: (D)

SSL is the abbreviation for Secure Sockets Layer, the original protocol designed to encrypt data in transit between a client and a server. This acronym directly matches the name of that protocol, which is why it’s the correct choice. While TLS later replaced SSL as the more secure standard, the legacy name SSL is still commonly used to refer to the encrypted channel itself. The other options refer to different concepts or protocols: SID isn’t related to encryption, SNMP is for managing network devices, and SMTPS denotes SMTP over SSL/TLS rather than the Secure Sockets Layer protocol itself.
