PCDE Migrate data solutions Practice Question
A data analyst needs to load data from an on-premises Teradata system into BigQuery on a recurring daily schedule. Which Google Cloud service should they use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
BigQuery Data Transfer Service
BigQuery Data Transfer Service is the correct service for scheduled, recurring data loads from on-premises Teradata into BigQuery. It supports Teradata via an agent-based transfer configuration. Cloud Composer is a workflow orchestration tool, not directly designed for this use case. Cloud Data Fusion provides ETL capabilities but is not the best fit for simple daily Teradata-to-BigQuery transfers. Database Migration Service is intended for migrating databases to Cloud SQL, not for loading data into BigQuery.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Cloud Composer
Why it's wrong here
Composer is a workflow orchestrator, not a direct data transfer service.
- ✗
Cloud Data Fusion
Why it's wrong here
Cloud Data Fusion is unsuitable for this scenario as it is primarily designed for complex ETL/ELT pipelines requiring extensive data transformation, cleansing, and orchestration across various sources, rather than a direct data load. While it can connect to Teradata and BigQuery, its strength lies in visual, code-free development of intricate data workflows. It is tempting as a general data integration platform and would be the correct choice if the requirement involved sophisticated data manipulation, aggregation, or joining multiple disparate datasets before loading into BigQuery.
- ✓
BigQuery Data Transfer Service
Why this is correct
Data Transfer Service supports Teradata scheduled transfers.
- ✗
Database Migration Service (DMS)
Why it's wrong here
DMS is for live migrations, not scheduled batch transfers.
