Question 40
Domain 4: Billing, Pricing, and SupportAn AWS customer wants to lower storage costs for data that is accessed infrequently but still must remain immediately available when requested. Which storage choice is the best fit?
Correct answer: B
Explanation
Use a lower-cost storage tier designed for infrequent access when data must still be retrieved immediately without archival delay. Archive tiers are better for rarely accessed data that can tolerate slower retrieval. — 05-AWS_Core_Services.md
Why each option is right or wrong
A. Choose an archive storage tier intended for long-term retention with delayed retrieval.
Archive tiers are intended for long-term retention and do not provide immediate access on request.
B. Choose an infrequent access storage tier intended for lower-cost storage with immediate retrieval.
The scenario requires both lower cost for infrequently accessed data and immediate availability when requested. An infrequent access storage tier matches those two conditions, unlike archive-oriented storage that trades cost for slower retrieval.
C. Choose a storage tier optimized for continuously accessed active data at standard rates.
Standard-access tiers are for frequently accessed active data rather than cost-optimized infrequent access.
D. Choose a storage option intended only for temporary caching rather than durable stored data.
Caching options are for temporary performance acceleration, not durable lower-cost storage tiers.
