Google Cloud Associate Data Practitioner — Question 60

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?

Answer options

• A. 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.
• B. Use the Cloud Data Fusion web interface to build data pipelines. Create a directed acyclic graph (DAG) that facilitates pipeline orchestration.
• C. Use the existing data pipeline tool’s BigQuery connector to reconfigure the data mapping.
• D. Use the BigQuery Data Transfer Service to recreate the data pipeline and migrate the data into BigQuery.

Correct answer: C

Explanation

The correct answer is C because using the existing data pipeline tool’s BigQuery connector directly optimizes the migration process by leveraging pre-built capabilities. Alternatives like creating temporary file systems or using other services might introduce unnecessary complexity and delays in the migration timeline.
