ITPEC FE Subject A October 2025 Question 23
ITPEC FE Subject A October 2025 — Question 23 of 60
QoS (Quality of Service) — mechanism to prioritize network traffic and minimize latency.
QoS assigns priority levels to different types of traffic, ensuring critical applications (VoIP, video streaming) get more bandwidth and lower latency than less important traffic.
Why not others:
- (a) AAA — Authentication, Authorization, Accounting — controls user access, not traffic priority
- (b) PoE — Power over Ethernet — delivers electrical power through Ethernet cables
- (d) RTP — Real-time Transport Protocol — carries audio/video data but is not a prioritization mechanism itself
Key rule: QoS = traffic prioritization + latency control for network applications.
