Which traffic class is typically Real-time, such as RTP voice?

• A. Best-effort
• B. Background
• C. Real-time
• D. Scavenger

Answer: (C)

Traffic in QoS is grouped by how sensitive it is to delay and jitter. Real-time traffic is the category for streams that must arrive with minimal delay, such as voice. RTP voice is highly delay- and jitter-sensitive, so it’s placed in the Real-time class to get the highest priority treatment (fast forwarding, low latency queuing) even when the network is busy. Other classes like Best-effort handle ordinary data without guarantees, Background is for large, delay-tolerant transfers, and Scavenger is the lowest priority. Mapping voice to the Real-time class ensures it receives the resources needed to maintain call quality.
