Remember, classification identifies, while marking modifies packet headers! --Microsoft Copilot

IPP Marking DSCP(Differentiated Service Code Point) By having generally agreed upon standard markings for different kinds of traffic. Default Forwarding (DF) - best effort traffic Expedited Forwarding (EF) - Low losslatency/jitter traffic Assured Forward Forwarding (AF) -

D is correct

D is the correct answer.

forgot to attach my vote lol

Answer is correct: Chatgpt: Marking is a QoS technique where a value is modified or added to a specific field in the packet header to indicate the class or priority of the packet. This marking can be used to differentiate and prioritize different types of traffic based on their specific requirements. For example, in IP-based networks, the Differentiated Services Code Point (DSCP) field in the IP header can be modified to set the class of service for a packet. By changing the value of the DSCP field, the packet is marked with a specific priority or class, allowing routers and switches along the network path to apply appropriate QoS policies and forwarding behaviors. Marking is crucial in QoS implementation as it enables network devices to identify and treat packets differently based on their class of service, ensuring that higher-priority traffic, such as voice or real-time applications, receives preferential treatment and appropriate QoS handling.
