AWS SAA-C03 - Practice Test #1
65 complete questions for AWS Solutions Architect Associate exam preparation.
A company generates 5 TB of log data daily. For compliance regulations, data must be retained for 5 years. During the first 30 days, logs are frequently accessed for analysis. After 30 days, they are rarely queried. If old data needs to be accessed after 30 days, a retrieval time of up to 12 hours is acceptable. Which Amazon S3 lifecycle strategy meets these requirements while being the MOST COST-EFFECTIVE solution?

Explanation
Detailed breakdown of the correct answer
Storage Cost Optimization
The access pattern is predictable: frequent access for the first 30 days and rarely thereafter, with a 12-hour retrieval window. Amazon S3 Glacier Deep Archive is the lowest-cost storage class in AWS, and its standard retrieval time is up to 12 hours, which perfectly fits the requirement.
Therefore, the correct answer is: Store data in S3 Standard and create an S3 Lifecycle rule to transition to S3 Glacier Deep Archive after 30 days. It meets the SLAs and offers the lowest price per GB/month.
The option that says: Use S3 Intelligent-Tiering... is incorrect because Intelligent-Tiering adds a monitoring and automation charge. If the access pattern is known and static (exactly 30 days), configuring manual S3 Lifecycle rules is cheaper than paying the monitoring fee.
The option that says: Transition to S3 Glacier Flexible Retrieval... is incorrect because, although Flexible Retrieval supports retrievals in minutes or a few hours, it is more expensive than Deep Archive. The scenario allows up to 12 hours of waiting, making Deep Archive the 'MOST COST-EFFECTIVE' choice.
The option that says: Transition them to S3 One Zone-IA... is incorrect because One Zone-IA is designed for infrequent access with millisecond retrieval and is significantly more expensive than Glacier classes for long-term (5 years) retention.
