Practice Tests & Scenarios
A company needs to store log files that are accessed frequently for the first 30 days, then rarely accessed but must be available within minutes. Which storage strategy is most cost-effective?
A) S3 Standard for all data
B) S3 Intelligent-Tiering
C) S3 Standard with lifecycle to Standard-IA after 30 days
D) S3 One Zone-IA for all data
Answer: C) S3 Standard with lifecycle to Standard-IA after 30 days
This provides optimal cost savings by using Standard for frequent access, then automatically transitioning to Standard-IA for infrequent access with immediate availability.
