CLF-C02 Question 225
Single answerYou are managing a large-scale data archival system that requires data to be stored at the lowest possible cost, but the data must still be retrievable within minutes if needed. Which Amazon S3 storage class should you choose?
- A
S3 Standard
- B
S3 Intelligent-Tiering
- C
S3 Glacier Instant Retrieval
- D
S3 Glacier Deep Archive
Show answer and explanation
Correct answer: C
Explanation
For archival data that must still be retrievable within minutes, S3 Glacier Instant Retrieval is the optimal choice. It combines low-cost storage with fast retrieval times, meeting the requirements of the scenario. Other storage classes like S3 Standard and S3 Intelligent-Tiering are not as cost-effective for archival purposes, and S3 Glacier Deep Archive has retrieval times that are too long for this use case.
- A. Incorrect.
S3 Standard is optimized for frequently accessed data and offers high availability and low latency but is not cost-effective for archival data.
- B. Incorrect.
S3 Intelligent-Tiering automatically moves data between tiers based on access patterns but is not the most cost-effective option for archival purposes.
- C. Correct.
S3 Glacier Instant Retrieval is specifically designed for archival data that requires quick retrieval (within milliseconds to minutes) and offers a low-cost storage solution.
- D. Incorrect.
S3 Glacier Deep Archive is the lowest-cost storage class, but retrieval times can take hours, making it unsuitable for use cases requiring fast access.
