DEA-C01 Question 242
Select 2A company is storing critical business data in Amazon S3. The company needs to implement a data retention policy where data older than 90 days must be archived for long-term storage at a lower cost, but still needs to be retrievable within minutes if required. Additionally, the company must ensure that any deleted data is retained for compliance purposes for at least 7 years. Which combination of actions should the company take to meet these requirements?
- A
Configure an S3 Lifecycle policy to transition objects older than 90 days to S3 Glacier Instant Retrieval.
- B
Enable S3 Object Lock in compliance mode with a retention period of 7 years.
- C
Use S3 Intelligent-Tiering to automatically move data to the most cost-effective storage tier.
- D
Configure an S3 Lifecycle policy to transition objects older than 90 days to S3 Glacier Flexible Retrieval.
- E
Enable versioning and configure a lifecycle rule to permanently delete non-current versions of objects after 7 years.
Show answer and explanation
Correct answers: A, B
Explanation
To meet the company's requirements, an S3 Lifecycle policy transitioning data older than 90 days to S3 Glacier Instant Retrieval ensures lower costs with fast retrieval. Enabling S3 Object Lock in compliance mode with a 7-year retention period ensures that deleted data is retained as per compliance requirements. Together, these actions fulfill both the cost optimization and compliance retention needs.
- A. Correct.
This option satisfies the requirement to archive data older than 90 days to a lower-cost storage class with retrieval within minutes, as S3 Glacier Instant Retrieval offers millisecond access times.
- B. Correct.
This option ensures that data cannot be deleted for a minimum of 7 years, meeting the compliance requirement for retaining deleted data.
- C. Incorrect.
Although S3 Intelligent-Tiering provides cost optimization, it does not allow for precise control over data retention policies or compliance requirements.
- D. Incorrect.
S3 Glacier Flexible Retrieval provides lower storage costs but has retrieval times in the range of minutes to hours, which does not satisfy the requirement for retrieval within minutes.
- E. Incorrect.
While enabling versioning is a good practice for data protection, permanently deleting non-current versions after 7 years would violate the compliance requirement to retain deleted data.
