Exam AWS Certified Security - Specialty SCS-C02 topic 1 question 192 discussion

While the log file prefix is important for organizing logs within the S3 bucket, the prefix does not need to exist beforehand. CloudTrail will automatically create the necessary directories (based on the prefix) in the S3 bucket when logs are delivered. The existence of the prefix itself is not a critical requirement for the delivery of CloudTrail logs.

To address the issue of CloudTrail failing to deliver events to Amazon S3, the initial actions you should take are: A. Verify that the S3 bucket policy allows CloudTrail to write objects. D. Verify that the S3 bucket defined in CloudTrail exists. These steps ensure that CloudTrail has the necessary permissions to write logs to the S3 bucket and that the specified bucket is correctly set up and accessible

obvious

AD. Prefix is optional when creating a trail

(E) According to this, log file prefixes should be configured correctly both in the bucket policy and in CTrail configuration. I am assuming if the bucket does not exist, the Trail configuration should fail prematurely. https://docs.aws.amazon.com/awscloudtrail/latest/userguide/turn-on-cloudtrail-in-additional-accounts.html

AE read the documentation

AD it is.

It's AD
