SCS-C02 Question 385
Select 2Your company stores critical logs in an Amazon S3 bucket. These logs must be retained for seven years to meet compliance requirements, after which they can be deleted. The company also wants to optimize storage costs by transitioning older logs to Amazon S3 Glacier Deep Archive after one year. Which configuration should you implement using an S3 Lifecycle policy to meet these requirements?
- A
Create a Lifecycle policy that transitions objects to S3 Glacier Deep Archive after one year and expires them after seven years.
- B
Create a Lifecycle policy that transitions objects to S3 Standard-IA after one year and expires them after seven years.
- C
Create a Lifecycle policy that transitions objects to S3 Glacier after one year and deletes them after seven years.
- D
Create a Lifecycle policy that transitions objects to S3 Glacier Deep Archive after one year and deletes them after seven years.
- E
Create a Lifecycle policy that transitions objects to S3 Glacier Deep Archive after seven years.
Show answer and explanation
Correct answers: A, D
Explanation
To meet the compliance and cost optimization requirements, a Lifecycle policy should transition objects to S3 Glacier Deep Archive after one year, as it is the most cost-effective storage class for long-term data. The objects should then be deleted after seven years to adhere to the data retention policy. Both options 1 and 4 satisfy these requirements.
- A. Correct.
Correct: This configuration transitions objects to S3 Glacier Deep Archive after one year, which is the desired storage class for cost optimization, and deletes them after seven years to meet compliance requirements.
- B. Incorrect.
Incorrect: Transitioning to S3 Standard-IA after one year is not cost-optimal compared to S3 Glacier Deep Archive for long-term storage.
- C. Incorrect.
Incorrect: Although transitioning to S3 Glacier is valid, S3 Glacier Deep Archive is more cost-effective for the stated use case.
- D. Correct.
Correct: This configuration also transitions objects to S3 Glacier Deep Archive after one year for cost optimization and deletes them after seven years, meeting the requirements.
- E. Incorrect.
Incorrect: Transitioning objects to S3 Glacier Deep Archive after seven years does not satisfy the requirement of optimizing costs starting after the first year.
