Topic 1 Question 66
Your organization has decided to migrate their existing enterprise data warehouse to BigQuery. The existing data pipeline tools already support connectors to BigQuery. You need to identify a data migration approach that optimizes migration speed. What should you do?
Create a temporary file system to facilitate data transfer from the existing environment to Cloud Storage. Use Storage Transfer Service to migrate the data into BigQuery.
Use the Cloud Data Fusion web interface to build data pipelines. Create a directed acyclic graph (DAG) that facilitates pipeline orchestration.
Use the existing data pipeline tool’s BigQuery connector to reconfigure the data mapping.
Use the BigQuery Data Transfer Service to recreate the data pipeline and migrate the data into BigQuery.

- 正解だと思う選択肢: C
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.
