The best answer is A. Adopt a rule-based extraction, transformation, and loading (ETL) framework . In PMI-CPMAI, the Identify Data Needs domain includes overseeing data cleaning, preprocessing, transformation, and validation so that data is suitable for model development. PMI's official exam outline specifically calls out defining data requirements, coordinating data cleaning and normalization, verifying preprocessing results, and ensuring the prepared data meets the format and quality needed for the intended AI approach.
An ETL framework is the most direct fit because the scenario is about getting telemetry data into the right format and shape for model use. ETL handles extraction from source systems, transformation into a usable model-ready structure, and loading into the target environment in a controlled, repeatable way. By contrast, DDS is more about data exchange architecture, not primary preparation for modeling. ML algorithms are used to learn from prepared data, not to format it. Batch processing may improve throughput, but performance optimization does not solve the core requirement of structuring and transforming the data correctly. Under PMI-CPMAI logic, data preparation should be systematic, auditable, and aligned to the model's requirements, which makes ETL the strongest answer.
