Question: Which two traffic types use the Real-Time Transport Protocol (RTP)? (Choose two.)
- video
- web
- file transfer
- voice
- peer to peer
Explanation: The Real-Time Transport Protocol (RTP) is a specialized communication protocol designed specifically to facilitate the end-to-end delivery of data with real-time characteristics, such as interactive audio and video. Within the framework of network applications, particularly those utilizing the User Datagram Protocol (UDP) for transport, voice and video traffic are the primary types that leverage RTP. These media-rich transmissions, which include services such as Voice over IP (VoIP) and live multimedia streaming, are highly sensitive to latency and jitter; consequently, they prioritize the rapid, continuous flow of information over the absolute reliability provided by connection-oriented protocols. While applications such as file transfers and web browsing rely on the retransmission and sequencing mechanisms of TCP to ensure data integrity, real-time multimedia streaming accepts a degree of packet loss in favor of maintaining a synchronized and uninterrupted user experience. To manage these requirements effectively, RTP is often deployed in conjunction with the Real-Time Transport Control Protocol (RTCP) to minimize latency issues and ensure the priority delivery of real-time packets across the network infrastructure.
