SAP-C02 Design for New Solutions Practice Question
A company wants to design a cost-effective solution to store infrequently accessed log files for 7 years. The logs are generated daily and must be available for retrieval within 24 hours. Which Amazon S3 storage class should be used?
⚠ Common exam trap
Watch out — candidates often confuse retrieval time requirements with access frequency, assuming that any 'Infrequent Access' class (like S3 One Zone-IA or S3 Standard-IA) is the best choice for archival, when in fact S3 Glacier Deep Archive is designed specifically for long-term, cost-effective archival with retrieval times that still meet the 24-hour window.

Correct answer & explanation
✓
S3 Glacier Deep Archive
Amazon S3 Glacier Deep Archive is the most cost-effective storage class for infrequently accessed data that must be retained for 7 years, with retrieval times of up to 12 hours (within the 24-hour requirement). It offers the lowest storage cost among S3 classes, making it ideal for long-term archival of log files that are rarely accessed.
