Designing for Cisco Internetwork Solutions (DESGN, legacy) — Question 37

In which layer of the OSI model does Real-Time Transport Protocol (RTP) operate?

Answer options

• A. Network
• B. Application
• C. Transport
• D. Session

Correct answer: C

Explanation

The Real-Time Transport Protocol (RTP) operates at the Transport layer of the OSI model, where it is responsible for delivering audio and video over networks. The other options, Network, Application, and Session, refer to different layers that serve distinct roles in data communication, but they do not handle the real-time transport of multimedia data like RTP does.
