Which of the following BEST describes a SAP when regarding QoS?

• A. A point in the network where EXP bits can be mapped to one of eight predefined FCs, each one with its own queue.
• B. A logical point in a service tunnel where all of customer traffic is aggregated.
• C. A point at which the initial classification of customer traffic occurs.
