How many DCPSs are associated with the BUS2 PMA?

The correct answer is based on the design and configuration of the MQ-9 aircraft's data communication systems. The BUS2 PMA (Power Management Architecture) is specifically designed with a single Data Communication Protocol Subsystem (DCPS) associated with it. The purpose of the DCPS is to facilitate communications and manage data flow within the various aircraft systems through the BUS2 network.

In the context of the MQ-9, having one DCPS ensures streamlined communication and coordination of functions handled by BUS2, thereby optimizing performance and reducing potential points of failure.

The other options either suggest a number of DCPSs that are less than or greater than the actual count, which does not reflect the established system architecture for the MQ-9. This focus on an accurate count of DCPSs is critical for understanding how the aircraft manages its power and communication systems effectively.
