- A
Transfer Appliance
Why wrong: Transfer Appliance is for offline petabyte-scale transfers, not for regular nightly transfers over the network.
- B
Storage Transfer Service
Storage Transfer Service is designed for online transfers between storage systems including S3 to GCS.
- C
BigQuery Data Transfer Service
Why wrong: BigQuery Data Transfer Service is for loading data directly into BigQuery from various sources, not for transferring files between cloud storage.
- D
Datastream
Why wrong: Datastream is for change data capture from databases, not for file transfers.

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.
A data engineer needs to schedule recurring nightly loads from Amazon S3 to Google Cloud Storage. The data is in CSV format and the volume is approximately 500 GB per night. 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
✓
Storage Transfer Service
The Storage Transfer Service is designed for online data transfers from external cloud providers like Amazon S3 to Google Cloud Storage. It supports scheduling recurring nightly transfers, handles large volumes (500 GB/night), and automatically retries failed transfers, making it the correct choice for this use case.
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
Cisco often tests the distinction between services that transfer data to Cloud Storage (Storage Transfer Service) versus services that load data directly into BigQuery (BigQuery Data Transfer Service), causing candidates to confuse the destination.
Detailed technical explanation
How to think about this question
The Storage Transfer Service uses gRPC-based parallel transfers and can be configured with a schedule using cron-like syntax. It supports incremental transfers by comparing object metadata (e.g., last modified time) to avoid re-transferring unchanged files, which is critical for nightly loads where only new or modified CSV files need to be moved. Under the hood, it leverages Google Cloud’s global network for optimized bandwidth and can handle up to 1 Gbps per transfer job.
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.
Quick reference
AWS S3 Storage Class Comparison
| Storage Class | Min Duration | Retrieval | Use Case |
|---|---|---|---|
| S3 Standard | None | Immediate | Frequently accessed data |
| S3 Standard-IA | 30 days | Immediate | Infrequent access, rapid retrieval |
| S3 One Zone-IA | 30 days | Immediate | Non-critical infrequent data |
| S3 Intelligent-Tiering | None | Immediate–hours | Unknown or changing access patterns |
| S3 Glacier Instant | 90 days | Milliseconds | Archive with instant retrieval |
| S3 Glacier Flexible | 90 days | Minutes–hours | Archive, flexible retrieval |
| S3 Glacier Deep Archive | 180 days | Hours | Long-term compliance archive |
