SAA-C03 Question 495
Single answerA financial services company needs to retain transaction logs for a period of 7 years to comply with regulatory requirements. The logs are accessed infrequently but must be immediately available when requested. Which solution provides the most cost-effective and compliant approach to meet these requirements?
- A
Store the logs in Amazon S3 Standard with a lifecycle policy to transition them to Amazon S3 Glacier Deep Archive after 7 years.
- B
Store the logs in Amazon S3 Intelligent-Tiering and configure a lifecycle policy to delete them after 7 years.
- C
Store the logs in Amazon S3 Glacier Instant Retrieval and configure a lifecycle policy to delete them after 7 years.
- D
Store the logs in Amazon S3 Standard-IA (Infrequent Access) with no lifecycle policy.
Show answer and explanation
Correct answer: B
Explanation
To meet the regulatory requirement of 7 years of data retention with immediate access, S3 Intelligent-Tiering provides a cost-effective solution. It automatically optimizes storage costs over time while ensuring that the logs are immediately accessible. Configuring a lifecycle policy to delete the data after 7 years ensures compliance with the retention policy.
- A. Incorrect.
Storing the logs in S3 Standard and transitioning them to Glacier Deep Archive after 7 years does not meet the requirement of immediate availability, as Glacier Deep Archive retrieval times are not instant.
- B. Correct.
S3 Intelligent-Tiering is a cost-effective storage class for data with unpredictable access patterns. It automatically moves objects to the most cost-efficient tier based on usage, and it ensures immediate availability, making it suitable for this scenario. Configuring a lifecycle policy to delete the logs after 7 years meets the retention requirement.
- C. Incorrect.
S3 Glacier Instant Retrieval provides instant access but is more expensive than S3 Intelligent-Tiering for this workload. It is not the most cost-effective solution.
- D. Incorrect.
S3 Standard-IA offers lower costs for infrequent access but does not automatically optimize for changing access patterns over time. It is less efficient compared to S3 Intelligent-Tiering for data with unpredictable access needs.
