WebRTC is almost exclusively used for what scenario?

• A. Internal service-to-service communication using binary Protocol Buffers.
• B. RESTful API access to static resources.
• C. Server-side event streaming to clients.
• D. Peer-to-peer audio/video calling and conferencing.

Answer: (D)

WebRTC is built for real-time, peer-to-peer communication directly between browsers, with a focus on interactive audio and video. It provides the mechanisms to capture media, negotiate a direct, encrypted connection between two peers, and stream media with very low latency. This makes it the natural choice for scenarios like peer-to-peer audio/video calling and conferencing, where participants communicate directly without routing media through a central server and where timely delivery and synchronization are essential. The other options describe patterns that aren’t about direct real-time media between browsers: internal service-to-service communication with binary Protocol Buffers is typical of backend RPCs; RESTful API access to static resources uses a request/response model over HTTP; server-side event streaming pushes updates from server to clients, but Media paths and peer-to-peer dynamics that WebRTC optimizes aren’t part of that model. WebRTC’s strengths lie in enabling real-time, direct communication between peers, which is why its most common use is for audio/video calling and conferencing.
