AWS Certified Solutions Architect – Associate (SAA-C02) — Question 90

A solutions architect is using Amazon S3 to design the storage architecture of a new digital media application. The media files must be resilient to the loss of an
Availability Zone. Some files are accessed frequently while other files are rarely accessed in an unpredictable pattern. The solutions architect must minimize the costs of storing and retrieving the media files.
Which storage option meets these requirements?

Answer options

• A. S3 Standard
• B. S3 Intelligent-Tiering
• C. S3 Standard-Infrequent Access (S3 Standard-IA)
• D. S3 One Zone-Infrequent Access (S3 One Zone-IA)

Correct answer: B

Explanation

The correct answer is B, S3 Intelligent-Tiering, as it automatically moves data between two access tiers when access patterns change, thus optimizing costs for both frequently and infrequently accessed files. Option A, S3 Standard, does not provide cost optimization for infrequent access, while C and D are focused on infrequent access scenarios and do not offer resilience to the loss of an Availability Zone.
