Voice traffic is experiencing excessive jitter. A network engineer wants to improve call performance and clarity. Which of the following features should the engineer configure?
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.
