- A
Transfer Appliance
Transfer Appliance is the right choice for petabyte-scale offline data transfer when network bandwidth is insufficient.
- B
BigQuery Data Transfer Service for Oracle
Why wrong: BigQuery Data Transfer Service does not support Oracle as a source.
- C
Datastream
Why wrong: Datastream is designed for ongoing change data capture (CDC), not for large initial bulk loads over slow networks.
- D
Storage Transfer Service
Why wrong: Storage Transfer Service is for transferring data between cloud storage systems (e.g., S3 to GCS), not from on-premises Oracle.
Question 169 of 1,000
PDE Ingesting and Processing the Data Practice Question
This PDE practice question tests your understanding of ingesting and processing the data. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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 data engineer needs to migrate 200 TB of on-premises Oracle data to BigQuery. The network bandwidth is limited to 100 Mbps, and the data must be loaded within 2 weeks. Which Google Cloud service is most appropriate for the initial data 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
✓
Transfer Appliance
Transfer Appliance is correct because it is a physical device designed for large-scale offline data transfers when network bandwidth is insufficient. With 200 TB at 100 Mbps, the theoretical transfer time exceeds 190 days, far beyond the 2-week window. Transfer Appliance allows shipping the data directly to Google, bypassing network constraints entirely.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

BigQuery Data Transfer Service for Oracle
Why it's wrong here
BigQuery Data Transfer Service does not support Oracle as a source.
- ✗
Datastream
Why it's wrong here
Datastream is designed for ongoing change data capture (CDC), not for large initial bulk loads over slow networks.
- ✗
Storage Transfer Service
Why it's wrong here
Storage Transfer Service is for transferring data between cloud storage systems (e.g., S3 to GCS), not from on-premises Oracle.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates may assume online services like Storage Transfer Service or BigQuery Data Transfer Service can handle large volumes if given enough time, ignoring the hard bandwidth calculation that proves 200 TB at 100 Mbps is impossible within 2 weeks.
Detailed technical explanation
How to think about this question
Transfer Appliance uses a ruggedized server with high-capacity storage (up to 480 TB per unit) that you physically ship to Google Cloud. Once received, the data is ingested into Cloud Storage, from which it can be loaded into BigQuery. The appliance supports encryption at rest and can be ordered with a specific data transfer job ID to track the process end-to-end.
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.
TExam Day Tips
- 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.
