Quality of Service (QoS) prioritizes delay-sensitive traffic such as VoIP by assigning higher priority in queues, reducing jitter, latency, and packet loss. Implementing QoS policies ensures stable and clear voice communication.
* B. STP (Spanning Tree Protocol) prevents switching loops, but it does not address jitter or real-time traffic performance.
