Which feature is least essential in a robust telemetry data pipeline?

• A. Data compression.
• B. Data prioritization.
• C. Data sampling control.
• D. Manual intervention only without automated handling.

Answer: (D)

Automation and resilience are at the heart of a robust telemetry data pipeline. Data compression helps reduce bandwidth and storage needs, which is vital when dealing with high-volume telemetry. Data prioritization makes sure the most important signals—like health indicators or critical alerts—get delivered first, even when resources are limited. Data sampling control lets you manage data volume while preserving meaningful information, so you can maintain a representative view of the system without overwhelming the pipeline. The approach that relies on manual intervention only without automated handling is least essential because robustness depends on automated, scalable processes. Manual steps introduce delays, inconsistency, and a lack of scalability across many devices and varying network conditions. Automated retry, backoff, failure handling, and continuous monitoring keep the pipeline reliable and responsive without requiring constant human effort.
