A. B. C. D.C.
The Quality of Service (QoS) mechanism is used to manage and prioritize network traffic to ensure that important traffic receives adequate bandwidth and is not impacted by other types of traffic. QoS achieves this by applying various techniques to control and shape traffic flow.
Out of the given options, the QoS component that alters a packet to change the way that traffic is treated in the network is "marking."
"Marking" is the process of adding a tag or value to a packet's header to identify the type of traffic it represents. Marking a packet allows network devices to differentiate between different types of traffic and apply appropriate QoS policies, such as prioritization, policing, and shaping.
For example, network administrators can use marking to identify voice and video traffic and apply a higher priority to these packets, ensuring that they receive sufficient bandwidth to maintain their quality. Similarly, marking can be used to identify lower-priority traffic such as file transfers and limit the amount of bandwidth they can use, ensuring that they do not impact the performance of higher-priority traffic.
To summarize, "marking" is a QoS component that alters a packet by adding a tag or value to its header to identify the type of traffic it represents, enabling network devices to apply appropriate QoS policies to prioritize or limit its bandwidth usage.
