- A
Export Teradata data to Cloud Storage and use BigQuery load jobs scheduled via Cloud Scheduler.
Why wrong: While possible, it's not using Data Transfer Service and adds complexity; Data Transfer Service is the recommended approach.
- B
Use Cloud Data Fusion to create a batch pipeline from Teradata to BigQuery.
Why wrong: Data Fusion is an ETL tool, but for simple scheduled transfers, Data Transfer Service is simpler and more integrated.
- C
Create a transfer config with source type 'Teradata', target dataset, and schedule frequency.
This is the correct way to set up periodic incremental transfers from Teradata to BigQuery.
- D
Use a BigQuery scheduled query to SELECT * FROM Teradata via federated query.
Why wrong: Federated queries are for querying external sources directly, not for scheduled transfers.
PCD Migrate Data Solutions Practice Question
This PCD practice question tests your understanding of migrate data solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A team is migrating a Teradata data warehouse to BigQuery using the BigQuery Data Transfer Service. They need to schedule regular incremental transfers. What is the correct configuration for the transfer?
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
Create a transfer config with source type 'Teradata', target dataset, and schedule frequency.
BigQuery Data Transfer Service for Teradata supports scheduled transfers. The correct setup is to configure a transfer config with a schedule (e.g., daily) and specify the dataset and table mappings. The service handles incremental loads based on a watermark column.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
