AWS Certified Solutions Architect – Associate (SAA-C03) — Question 17

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, optimizing costs while ensuring durability across Availability Zones. Option A, S3 Standard, is more expensive for infrequently accessed data, while C and D are unsuitable since S3 Standard-IA and S3 One Zone-IA do not provide the needed resilience against the loss of an Availability Zone.
