Which statement about NDL is true?

Which statement about NDL is true?

• A. NDL is the shell you start with to edit an IDL.
• B. NDL data is used to create IDLs via JMPS.
• C. NDL is used to modify IPF settings in FAA airspace.
• D. NDL is used to transmit PPLI data on the network.

Answer: (B)

NDL is a planning input that describes the data-link network and how units will exchange information. In the workflow, you model the network in NDL, and then a tool like JMPS uses that description to generate the Interface Description Language files that define how the Link 16 data link should be implemented or simulated. That connection—NDL as the source data used by JMPS to create IDLs—is why this statement is the correct one. The other options mix up roles: NDL isn’t a shell for editing IDLs, it isn’t something you use to change FAA IPF settings, and it isn’t the mechanism by which PPLI data is transmitted on the network.
