PDE Preparing and Using Data for Analysis Practice Question
An organization wants to integrate BigQuery Omni to query data stored in AWS S3. They have set up the necessary connections. What is the primary benefit of using BigQuery Omni over simply copying the data to BigQuery?
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
✓
Ability to use BigQuery ML models on data in S3 without moving data.
BigQuery Omni allows you to query data across clouds without moving it, providing a unified analytics experience. It reduces data egress costs and avoids duplication.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Ability to use BigQuery ML models on data in S3 without moving data.
Why this is correct
BigQuery Omni supports BigQuery ML, allowing you to train and run models on cross-cloud data.
- ✗
Automatic encryption of data at rest in S3.
Why it's wrong here
BigQuery Omni does not change S3 encryption settings.
- ✗
Lower latency queries due to in-memory caching.
Why it's wrong here
BigQuery Omni queries may have higher latency than querying data stored in BigQuery natively.
- ✗
Support for real-time streaming inserts into S3.
Why it's wrong here
BigQuery Omni is for batch querying, not streaming inserts.
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 |
