SOA-C02 Question 115
Select 3You are a SysOps Administrator tasked with setting up Amazon S3 Cross-Region Replication (CRR) for a bucket that stores critical business data. After configuring CRR, you notice that no objects are being replicated to the destination bucket. Which of the following steps should you take to troubleshoot and ensure CRR is working correctly?
- A
Ensure versioning is enabled on both the source and destination buckets.
- B
Verify that the IAM role associated with the replication configuration has the required permissions.
- C
Confirm that objects in the source bucket have the 'public-read' ACL set.
- D
Check if the replication rule is enabled in the source bucket's configuration.
- E
Confirm that the source bucket and destination bucket are in the same AWS Region.
Show answer and explanation
Correct answers: A, B, D
Explanation
To ensure Amazon S3 CRR functions correctly, certain prerequisites must be met: versioning must be enabled on both buckets, the IAM role must have the necessary permissions, and the replication rule must be enabled in the configuration. Additionally, CRR is designed for cross-region replication, so the buckets must be in different Regions. Objects' ACL settings, such as 'public-read', are not a factor in CRR functionality.
- A. Correct.
Versioning must be enabled on both the source and destination buckets for CRR to work. Without versioning, replication cannot occur.
- B. Correct.
The IAM role associated with the replication configuration must have permissions to replicate objects to the destination bucket. If the role lacks sufficient permissions, replication will fail.
- C. Incorrect.
CRR does not require objects to have a 'public-read' ACL. This is unrelated to the replication process.
- D. Correct.
Replication rules must be enabled for CRR to function. If the rule is not enabled, no objects will be replicated.
- E. Incorrect.
CRR specifically replicates data between buckets in different AWS Regions. If the buckets are in the same Region, Same-Region Replication (SRR) would be used instead of CRR.
