DEA-C01 Question 218
Select 2Your company stores large volumes of data in Amazon S3. To optimize costs, you need to implement a solution that automatically moves objects that are infrequently accessed to a lower-cost storage class and deletes objects that are no longer needed after a year. Which combination of actions should you take to meet these requirements?
- A
Configure an S3 Lifecycle policy to transition objects to S3 Standard-IA after 30 days and delete them after 365 days.
- B
Manually move objects to S3 Glacier Deep Archive after 60 days using the AWS Management Console.
- C
Enable S3 Intelligent-Tiering on all buckets to automatically move objects to the most cost-effective storage tier.
- D
Set up an S3 Lifecycle configuration to transition objects to S3 Glacier Deep Archive after 60 days and delete them after 365 days.
- E
Use AWS Glue to identify and move infrequently accessed data to lower-cost storage tiers.
Show answer and explanation
Correct answers: A, D
Explanation
To meet the requirements of transitioning infrequently accessed data to a lower-cost storage class and deleting expired data automatically, S3 Lifecycle policies are the best solution. Configuring lifecycle rules allows you to automate these processes effectively. While S3 Intelligent-Tiering optimizes costs, it does not fulfill the deletion requirement. Manual processes and using AWS Glue are not suitable for this scenario as they lack automation or are unrelated to lifecycle management.
- A. Correct.
Correct. This option directly uses S3 Lifecycle policies to transition data to a lower-cost storage class and delete objects after a specific period, addressing both requirements efficiently.
- B. Incorrect.
Incorrect. Manually moving objects is not automated and does not align with the requirement for automatic lifecycle management.
- C. Incorrect.
Incorrect. While S3 Intelligent-Tiering optimizes storage costs, it does not support automatic deletion of objects after a specific duration, which is required in this scenario.
- D. Correct.
Correct. Configuring an S3 Lifecycle policy to transition objects to S3 Glacier Deep Archive and delete them after 365 days meets both the cost optimization and data deletion requirements.
- E. Incorrect.
Incorrect. AWS Glue is a data processing service and is not designed for managing the lifecycle of data stored in S3.
