UDP is best for what type of transmission?

UDP is best for what type of transmission?

• A. Large file transfers requiring reliability
• B. Streaming video with strict error correction
• C. Sending small amounts of data where guaranteed delivery is not required
• D. Secure encrypted communications

Answer: (C)

UDP is designed for speed and low overhead. It’s a connectionless, best-effort protocol that doesn’t guarantee delivery, order, or protection against duplicates. That makes it ideal for sending small bursts of data where losing a packet isn’t critical and low latency is more important than perfect reliability. For example, quick control messages or simple queries can get there fast without the delay of waiting for acknowledgments. If you need guaranteed delivery for large file transfers, a reliable transport like TCP is a better fit. Streaming video that requires strict error correction would either need reliability mechanisms on top of UDP or a protocol that provides guarantees, since UDP alone won’t ensure all packets arrive in order. Encrypted communications can run over UDP (such as DTLS), but the primary reason to choose UDP in this scenario is its low overhead and suitability for non-critical data.
