What is that API?
A. A sequence packet listener (SPL) API that specifies the Director role and the match criteria for the packets
B. A listener API that registers the application to listen for data paths
C. A listener API that registers the application to listen for meters
D. A sequence packet listener (SPL) API that specifies the Advisor role and the match criteria for the packets
