What is a typical validation process for a telemetry system prior to deployment?

• A. Marketing approval, user surveys, and legal review.
• B. Only unit testing.
• C. Code compilation and static analysis.
• D. Requirements review, unit testing, integration testing, emulator testing, field testing, performance validation, safety review, and acceptance testing.

Answer: (D)

A telemetry system needs a multi-stage validation process before deployment to ensure it meets requirements and operates reliably in real-world conditions. Starting with a requirements review ensures what the system is supposed to do is clear and testable. Unit testing checks individual components in isolation, confirming they behave as intended. Integration testing then verifies that these components interact correctly as a whole. Emulator testing uses simulated environments to exercise the system without real-world risks, while field testing puts it through actual operational conditions. Performance validation checks that the system meets timing, throughput, and resource limits. Safety review identifies and mitigates potential hazards, and acceptance testing confirms the system satisfies stakeholder needs and is ready for deployment. The other options miss essential parts of this process: they either focus on non-technical aspects like marketing and surveys, rely on only one type of testing, or rely solely on static analysis, which cannot capture real behavior, performance, or safety in operation.
