Exam Associate Data Practitioner topic 1 question 66 discussion

The best option is C. Use the existing data pipeline tool’s BigQuery connector. Option C is best because leveraging existing tools and their BigQuery connectors is generally the fastest migration path. Reconfiguring existing mappings is more direct than introducing new services or intermediate steps, optimizing migration speed. Option A (Temporary file system and Storage Transfer Service) is incorrect because adding Cloud Storage as an intermediary step slows down migration compared to direct transfer. Option B (Cloud Data Fusion) is incorrect because building new pipelines in Data Fusion adds complexity and time, less optimal for speed if connectors already exist. Option D (BigQuery Data Transfer Service) is incorrect because Data Transfer Service is for scheduled transfers, not necessarily the fastest for a one-time bulk migration compared to direct connector usage. Therefore, Option C, using existing connectors, is the most direct and speed-optimized approach.
