For those who chose B, how can it be correct? an SCP denying s3:GetObject will deny access to the objects regardless if it is from the public or within the account... B will render the bucket inaccessible.

Answer is B Enabling the PublicAccessBlock configuration on the S3 bucket prevents public access. Additionally, configuring an SCP (Service Control Policy) to deny the s3:GetObject action for the organizational unit (OU) containing the AWS account ensures that the bucket remains private.

By configuring an SCP to deny the s3:GetObject action prevents accessing S3 objects from public, but deny the s3:PutPublicAccessBlock action, prevent any changes to the disable PublicAccessBlock settings, ensuring that the bucket remains private in future.

Selected Answer: C

Enable PublicAccessBlock Configuration: https://aws.amazon.com/s3/features/block-public-access/?nc1=h_ls Configure an SCP (Service Control Policy): An SCP is a policy that you can attach to an AWS Organization, organizational unit (OU), or an account. It acts as a guardrail to control permissions across accounts. In your case, you want to deny the s3:PutPublicAccessBlock action for the OU containing your AWS account. Go to the AWS Organizations console. Navigate to the OU that contains your account. Create a new SCP or edit an existing one. Add a statement that denies the s3:PutPublicAccessBlock action for the relevant S3 buckets. Attach the SCP to the OU. Ensure that your AWS account is part of the OU.
