AWS Certified Cloud Practitioner — Question 279

What does the Amazon S3 Intelligent-Tiering storage class offer?

Answer options

• A. Payment flexibility by reserving storage capacity
• B. Long-term retention of data by copying the data to an encrypted Amazon Elastic Block Store (Amazon EBS) volume
• C. Automatic cost savings by moving objects between tiers based on access pattern changes
• D. Secure, durable, and lowest cost storage for data archival

Correct answer: C

Explanation

Amazon S3 Intelligent-Tiering automatically optimizes storage costs by shifting objects between access tiers when access patterns change, requiring no operational overhead or retrieval fees. Other storage classes like S3 Glacier Deep Archive are designed for ultra-low-cost long-term archiving, while Amazon EBS is a block storage service unrelated to S3 storage classes.
