Which two items are included in RF communications systems that support end-to-end communications?

• A. RF circuits and Transit Links
• B. Line of Sight and Long-range
• C. ADNS Router and INE Device
• D. NIPRNET and SIPRNET

Answer: (A)

The main idea is that end-to-end RF communications rely on both the hardware at the endpoints and the wireless path between them. RF circuits are the end devices’ front ends—the transmitters, receivers, modulators, demodulators, filters, and amplifiers that generate and process the RF signal. Transit links are the actual wireless paths that carry the modulated signal from one radio to the other, whether through space, through repeaters, or other link architectures. Together, these two elements enable the signal to travel from source to destination. The other options describe characteristics (like line-of-sight or long-range) or separate network components and devices, which don’t represent the two essential items that make up RF end-to-end communication.
