DEA-C01 Question 243
Select 2A healthcare organization stores patient data in an Amazon S3 bucket. Due to compliance requirements, the organization must retain the data for 7 years but minimize storage costs for data that is not frequently accessed after 1 year. How can the organization configure its data retention and archiving strategy in the most cost-effective way while meeting compliance requirements?
- A
Use S3 Lifecycle policies to transition data to S3 Glacier Flexible Retrieval after 1 year and delete the data after 7 years.
- B
Store the data in S3 Intelligent-Tiering for the first year and then transition it to S3 Glacier Deep Archive for the remaining 6 years.
- C
Keep the data in S3 Standard for the first year and then move it to S3 One Zone-Infrequent Access for the remaining 6 years.
- D
Use S3 Lifecycle policies to transition data to S3 Standard-IA after 1 year and to S3 Glacier Flexible Retrieval after 5 years.
- E
Configure S3 Versioning and enable MFA Delete to prevent accidental deletion of the data.
Show answer and explanation
Correct answers: A, B
Explanation
The correct answers involve using S3 Lifecycle policies and storage classes to meet the requirements of long-term data retention and cost optimization. S3 Glacier Flexible Retrieval and S3 Glacier Deep Archive provide cost-effective storage for infrequently accessed data. S3 Intelligent-Tiering is ideal for the initial storage period, where access patterns may vary. These strategies ensure compliance with data retention policies while minimizing costs.
- A. Correct.
This option is correct as it allows the organization to transition data to a cheaper storage tier (S3 Glacier Flexible Retrieval) after 1 year and delete it after 7 years, fulfilling retention and compliance requirements.
- B. Correct.
This option is also correct since S3 Intelligent-Tiering optimizes costs for the first year, and transitioning to S3 Glacier Deep Archive ensures the lowest cost for long-term storage over the remaining 6 years.
- C. Incorrect.
This option is incorrect because S3 One Zone-IA is not ideal for critical data like healthcare records due to its lack of redundancy, and it may not comply with regulatory requirements.
- D. Incorrect.
This option is incorrect because transitioning to S3 Standard-IA for 4 years before moving to S3 Glacier Flexible Retrieval does not optimize costs as effectively as moving directly to Glacier after 1 year.
- E. Incorrect.
This option is partially relevant but does not address the primary requirement of cost optimization and compliance through lifecycle transitions.
