Explanation

NTP (Network Time Protocol) is specifically designed to synchronize clocks across network devices - routers, switches, servers, and clients - to a common time reference, making it the correct answer.

Why the distractors are wrong:

• RTP (Real-time Transport Protocol) handles the delivery of audio/video streams, not clock synchronization
• STP (Spanning Tree Protocol) prevents Layer 2 switching loops in Ethernet networks - completely unrelated to time
• TDF is not a standard networking protocol acronym in this context

Memory tip: Think of NTP as the "time cop" of the network - the "T" stands for Time, and it's been keeping networks in sync since the 1980s. If a question mentions clocks, timestamps, or time synchronization across devices, NTP is almost always the answer.
