Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
S3 Standard: Designed for frequently accessed data with low latency and high throughput.
Correct matches: S3 Standard for frequently accessed data, S3 Intelligent-Tiering for automatic cost optimization, and S3 Glacier for archival. Common confusions involve mixing up Standard-IA and Glacier Deep Archive definitions.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
S3 Standard: Designed for frequently accessed data with low latency and high throughput.
Why this is correct
S3 Standard is the default storage class for frequently accessed data, providing low latency and high throughput.
S3 Intelligent-Tiering: Automatically moves data between access tiers to optimize costs.
Why this is correct
S3 Intelligent-Tiering monitors access patterns and moves data to the most cost-effective tier.
S3 Glacier: Long-term archival with retrieval times from minutes to hours.
Why this is correct
S3 Glacier is designed for archival data that is accessed infrequently, with retrieval times ranging from minutes to hours.
S3 Standard-IA: Lowest-cost storage class for long-term retention with retrieval times of 12 hours.
Why it's wrong here
Incorrect. This describes S3 Glacier Deep Archive, which has the lowest cost and retrieval times of 12 hours. S3 Standard-IA is for infrequently accessed data requiring rapid access.
S3 Glacier Deep Archive: For data accessed less frequently but requires rapid access when needed.
Why it's wrong here
Incorrect. This describes S3 Standard-IA (Infrequent Access), which is for data accessed less frequently but with rapid access needs. S3 Glacier Deep Archive is for long-term archival with very slow retrieval.
Quick reference
| 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 |
