DEA-C01 Question 220
Select 2You are designing a data management strategy for a company that processes large volumes of e-commerce transaction data in Amazon S3. The data needs to be stored for 7 years to meet compliance requirements, but after 1 year, it is infrequently accessed. To optimize storage costs, how can you manage the lifecycle of this data effectively?
- A
Create an S3 Lifecycle policy to transition the data to S3 Glacier Instant Retrieval after 1 year and delete it after 7 years.
- B
Use S3 Intelligent-Tiering to automatically optimize the storage cost for the data over its lifecycle.
- C
Create an S3 Lifecycle policy to transition the data to S3 Standard-IA after 1 year and S3 Glacier Deep Archive after 3 years, then delete it after 7 years.
- D
Store the data in S3 One Zone-IA from the start to reduce costs and delete it after 7 years.
- E
Manually move the data to S3 Glacier after 1 year using the AWS Management Console.
Show answer and explanation
Correct answers: A, C
Explanation
Managing the lifecycle of data in Amazon S3 can be optimized using S3 Lifecycle policies. Transitioning infrequently accessed data to lower-cost storage classes such as S3 Glacier Instant Retrieval, S3 Standard-IA, or S3 Glacier Deep Archive significantly reduces storage costs while ensuring compliance with retention requirements. Automated policies are preferred over manual processes to reduce human error and improve efficiency.
- A. Correct.
Correct: Configuring an S3 Lifecycle policy to transition the data to S3 Glacier Instant Retrieval after 1 year optimizes storage for infrequently accessed data. Deleting it after 7 years meets compliance requirements.
- B. Incorrect.
Partially correct, but not optimal: S3 Intelligent-Tiering automatically manages storage costs but incurs additional monitoring fees and may not be the most cost-effective solution for long-term infrequently accessed data.
- C. Correct.
Correct: Using an S3 Lifecycle policy to transition the data through S3 Standard-IA and S3 Glacier Deep Archive is a cost-effective and automated way to manage the lifecycle of data while meeting retention requirements.
- D. Incorrect.
Incorrect: S3 One Zone-IA is not suitable for critical data that requires durability across multiple Availability Zones. It also doesn't address the infrequent access and long-term storage needs.
- E. Incorrect.
Incorrect: Manually managing the data lifecycle is error-prone and inefficient when AWS provides automated lifecycle management options like S3 Lifecycle policies.
