What happens when you click "TEST" while setting up an AWS bucket?

When you click "TEST" while setting up an AWS bucket, a test archive file is created to verify your AWS permissions. This process is crucial for ensuring that the connection between your Splunk instance and the AWS bucket is configured correctly. The creation of this test archive provides a practical means of confirming that the necessary permissions are in place for Splunk to access and interact with the AWS services.

This test file allows administrators to verify that the IAM role and policy permissions assigned are functioning appropriately and that data can be written to the specified bucket as needed without actual data transfers occurring at this stage. By doing so, the setup can be validated before any critical operations are executed, reducing the likelihood of encountering permission-related issues during actual data operations.
