- A
Cloud Dataproc
Why wrong: Dataproc is a managed Spark/Hadoop service; requires writing and maintaining code to load data.
- B
BigQuery Data Transfer Service
Supports Amazon S3 as a source for scheduled transfers directly into BigQuery.
- C
Cloud Composer
Why wrong: Composer is Apache Airflow-based orchestration; can be used but requires custom DAGs, not a turnkey transfer service.
- D
Cloud Storage Transfer Service
Why wrong: Storage Transfer Service copies objects between GCS and external clouds, but does not load into BigQuery directly.
Question 588 of 1,000
PDE Ingesting and Processing the Data Practice Question
This PDE practice question tests your understanding of ingesting and processing the data. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 ingest daily Salesforce reports into BigQuery without writing custom code. The reports are exported to an Amazon S3 bucket on a schedule. Which service should they use to automate 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
✓
BigQuery Data Transfer Service
The BigQuery Data Transfer Service (BQDTS) is the correct choice because it natively supports scheduled, automatic ingestion of Salesforce reports into BigQuery without requiring any custom code. It connects directly to the Salesforce API, extracts the reports, and loads them into BigQuery tables on a user-defined schedule, handling incremental updates and schema detection automatically.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Cloud Composer
Why it's wrong here
Composer is Apache Airflow-based orchestration; can be used but requires custom DAGs, not a turnkey transfer service.
- ✗
Cloud Storage Transfer Service
Why it's wrong here
Storage Transfer Service copies objects between GCS and external clouds, but does not load into BigQuery directly.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Cloud Storage Transfer Service (which only moves files between storage buckets) with BigQuery Data Transfer Service (which directly ingests from SaaS applications like Salesforce into BigQuery), leading them to pick option D when the requirement is for a no-code, direct-to-BigQuery solution.
Detailed technical explanation
How to think about this question
Under the hood, BQDTS uses the Salesforce Bulk API 2.0 to efficiently export large volumes of report data, handling rate limits and pagination automatically. It supports both full refresh and incremental loads based on the report's last modified timestamp, and it can automatically create or update BigQuery tables with the correct schema derived from the Salesforce report fields. A real-world scenario where this matters is when a company needs daily syncing of sales pipeline data from Salesforce to BigQuery for analytics, and BQDTS eliminates the need to manage API credentials, retries, or scheduling infrastructure.
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 |
