AWS Certified Solutions Architect Associate SAA-C03 Practice Question
An e-commerce application has seasonal peaks that drive short-term surges in user traffic and data storage. The solution must remain highly available and performant during holiday spikes while keeping storage costs low the rest of the year. Which AWS storage option best meets these requirements?
Use Amazon S3 Intelligent-Tiering to automatically move data among frequent, infrequent, and archive access tiers.
Set up multiple EBS volumes with different sizes and manually switch between them based on expected traffic.
Store all data in Amazon S3 Glacier to achieve cost savings on storage during low-traffic periods.
Create a large S3 bucket to handle potential spikes without enabling any cost-optimization features.
Amazon S3 Intelligent-Tiering is designed for data with unpredictable or changing access patterns. It monitors each object and, after 30 days of no access, moves it from the Frequent Access tier to the lower-cost Infrequent Access tier. After 90 days, objects transition to the Archive Instant Access tier, and (if enabled) to Archive Access and Deep Archive tiers after 90 and 180 days, respectively. If an object is later accessed, it is automatically returned to the Frequent tier-providing consistent performance while minimizing cost.
S3 Standard without Intelligent-Tiering never moves objects to cheaper tiers, so long-term storage costs stay high. EBS volumes must be manually resized or automated with custom scripts; they do not elastically grow and shrink with demand. S3 Glacier classes are intended for archival data: retrieval takes minutes to hours, making them unsuitable for a production e-commerce workload that needs immediate access.
