SAP-C02 Design for New Solutions Practice Question
A company is designing a new application that will store and retrieve large files (up to 5 TB). The files must be accessible via HTTPS and must be durable. Which AWS storage service should be used?
⚠ Common exam trap
A common mix-up: candidates confuse file storage (EFS) or block storage (EBS) with object storage (S3), overlooking that only S3 provides native HTTPS access and 11 nines durability for large objects without requiring an EC2 instance or additional infrastructure.
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
✓
Amazon S3
Amazon S3 is the correct choice because it supports objects up to 5 TB in size, provides HTTPS access via RESTful API endpoints, and offers 99.999999999% (11 nines) durability by automatically replicating data across multiple Availability Zones. S3 is purpose-built for storing and retrieving large files over the internet with high durability and scalability.

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 |
