Which of the following is a protocol that describes an approach to providing "streamlined" support of OSI application services on top of TCP/IP-based networks for some constrained environments?

Explanation

Lightweight Presentation Protocol (LPP) is correct because its very name signals its purpose - "lightweight" is a direct synonym for "streamlined," and LPP (RFC 1085) was specifically designed to provide a simplified mechanism for running OSI application-layer services over TCP/IP networks in constrained environments where full OSI stack support isn't practical.

Why the distractors are wrong:

• A (NNTP) is for distributing and reading Usenet newsgroup articles - it has nothing to do with OSI service mapping.
• C (IRC) is a real-time text messaging/chat protocol, unrelated to OSI application service bridging.
• D (DHCP) dynamically assigns IP addresses and network configuration to hosts - it operates at a completely different layer and purpose.

Memory tip: The answer hides in plain sight - the question uses the word "streamlined" and the correct answer contains the word "Lightweight." On exam day, match the synonym: streamlined = lightweight = LPP.
