Explanation
MQC (Modular QoS CLI) is built on three foundational elements: flow strategy (A), which defines the overall approach to handling traffic flows; traffic classification (B), which uses class-maps to identify and group packets based on criteria like DSCP, ACLs, or protocols; and traffic behavior (D), which uses policy-maps to define actions (marking, shaping, policing, queuing) applied to classified traffic.
Option C (Stream discarding) is incorrect because it is not a recognized MQC component - MQC may include dropping/discarding as a behavior action, but "stream discarding" is not one of the three structural pillars of the framework itself.
Memory tip: Think of MQC as "Classify → Behave → Flow" - first you classify traffic, then you define its behavior, and your flow strategy ties it all together. If an answer choice sounds like a sub-action within a behavior (like "discard"), it's likely a distractor, not a core element.
