Question 3
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.
  • D: A point in the network where QoS parameters are discarded in favor of lower-level hardware queuing functions, such as LLI (Link Layer Interleave).
