Which of the following best describes a data link with reliable signal when viewing telemetry for a drone?

• A. Intermittent link with occasional interference
• B. Low latency link with poor error checking
• C. Reliable link with little interference
• D. High bandwidth with no routing security

Answer: (C)

The main idea here is that reliable telemetry comes from a stable data link with minimal interference, so data packets arrive consistently and accurately. A link that has little interference means fewer random disturbances, so there are fewer corrupted or lost packets and the ground station sees up-to-date, correct information about altitude, speed, battery, and other metrics. Intermittent connections with interference cause gaps in the data, which breaks the stream of telemetry. A fast link that lacks proper error checking might deliver data quickly but can also pass along corrupted information if errors aren’t detected and corrected. A link described by high bandwidth but without attention to reliability or security focuses on speed rather than stability; even very fast links can fail if interference or errors occur. In practice, the best choice is a reliable link with little interference, ensuring dependable and accurate telemetry.
