Question: Which of the following SEAL-C reference points is NOT supported for Uncrewed Aerial System (UAS) as per the specified functional architecture?
Option 1: LM-C reference point for location management
Option 2: GM-C reference point for group management
Option 3: DM-C reference point for data monitoring
Option 4: NRM-C reference point for network resource management
Explanation: The correct answer is Option 3 because the supported SEAL-C reference points for UAS include LM-C, GM-C, CM-C, IM-C, KM-C, and NRM-C. There is no mention of DM-C as a supported reference point, making it the correct choice as the NOT supported option.
