- A
Export data from Teradata to CSV files, upload to GCS using gsutil, then load into BigQuery.
Why wrong: This works but requires manual steps and is less efficient than the dedicated transfer service.
- B
Use Dataproc to run a Spark job that reads from Teradata and writes to BigQuery.
Why wrong: This adds complexity; the Data Transfer Service is simpler and purpose-built.
- C
Use Transfer Appliance to ship the data offline.
Why wrong: With a 10 Gbps connection, online transfer is faster and more practical.
- D
Use BigQuery Data Transfer Service for Teradata
This service automates the transfer from Teradata to BigQuery, handling schema and data types.

PDE Ingesting and Processing the Data Practice Question
This PDE practice question tests your understanding of ingesting and processing the data. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
You need to perform a one-time migration of historical data from an on-premises Teradata data warehouse to BigQuery. The data volume is 50 TB and you have a high-speed network connection (10 Gbps). What is the most efficient way to load the data?
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
✓
Use BigQuery Data Transfer Service for Teradata
BigQuery Data Transfer Service for Teradata is designed for this purpose; it can directly connect to Teradata and transfer data to BigQuery. Exporting to CSV then loading via gsutil is possible but less efficient. Transfer Appliance is for offline transfer but you have high-speed network. Dataproc is not needed.
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 healthcare organisation deploys an application with a public-facing web tier and a private database tier. The database subnet has no public IP and only accepts connections from the web tier's security group. Questions like this test whether you can design cloud network isolation using VNets/VPCs, subnets, and security group rules.
