An administrator is configuring a network to prioritize VoIP traffic over HTTP traffic to ensure call quality during peak hours. Which QoS mechanism should be used to categorize and manage these differing types of traffic effectively?
Load balancing
Class of Service (CoS)
Traffic shaping
Packet sniffing
Class of Service (CoS) is a Quality of Service (QoS) mechanism that operates at Layer 2 to mark frames with a priority level. This allows network devices to categorize traffic and prioritize sensitive data, such as VoIP packets, over less time-sensitive traffic like HTTP. This process is crucial for maintaining call quality during periods of network congestion. Traffic shaping is a different QoS technique focused on controlling the rate of traffic flow rather than prioritizing by type. Packet sniffing is a monitoring tool used to capture and analyze network traffic, not manage it. Load balancing distributes traffic across multiple network paths or servers to improve availability and performance but does not inherently prioritize traffic based on its type.
