SOA-C02 Question 114
Select 4You are managing an S3 bucket in the us-east-1 region that stores critical data for your organization. To ensure this data is backed up automatically in the eu-west-1 region, you enable Cross-Region Replication (CRR). After configuring the replication, you notice that no objects are being replicated. Which of the following actions should you take to troubleshoot and resolve the issue?
- A
Verify that versioning is enabled on both the source and destination buckets.
- B
Check if the destination bucket policy allows the necessary permissions for replication.
- C
Ensure that all objects in the source bucket have the 'CRR' tag specified in the replication rule.
- D
Confirm that the replication IAM role has the required permissions for replication.
- E
Manually copy existing objects from the source bucket to the destination bucket as Cross-Region Replication only applies to new objects.
Show answer and explanation
Correct answers: A, B, D, E
Explanation
Cross-Region Replication (CRR) requires versioning to be enabled on both the source and destination buckets, appropriate permissions in the destination bucket policy, and a properly configured replication IAM role. Additionally, CRR does not replicate existing objects; only new objects or updates to existing objects are replicated. To resolve the issue, you must verify these configurations and manually copy existing objects if necessary.
- A. Correct.
Versioning must be enabled on both the source and destination buckets for Cross-Region Replication to work. Without this, replication will fail.
- B. Correct.
The destination bucket policy must allow replication permissions for the specified IAM role. Without these permissions, the replication process cannot work.
- C. Incorrect.
Replication is not dependent on an 'CRR' tag being applied to objects. This is incorrect because replication rules are based on bucket-level settings or prefix/object filters.
- D. Correct.
The IAM role created for replication must have adequate permissions to access both the source and destination buckets. Without these permissions, replication tasks will not proceed.
- E. Correct.
Cross-Region Replication only applies to objects that are uploaded or modified after the replication configuration is enabled. Existing objects must be manually copied if replication of those objects is required.
