SCS-C03 Exam Dumps : AWS Certified Security – Specialty

AWS best practices require CloudFormation to assume a dedicated service role. This ensures consistent permissions regardless of the user. Users must have iam:PassRole permission to pass the role. Updating stacks to use the service role enforces uniform deployment behavior.

Encrypted EBS snapshots that use the default AWS managed key cannot be shared across accounts. AWS documentation states that only snapshots encrypted with a customer managed key can be shared, and the customer managed key must also allow the destination account or automation role to use it. Therefore, the target accounts need customer managed KMS keys and appropriate KMS permissions for the automation role. The security account also needs permissions to use its own customer managed key when copying and re-encrypting the evidence snapshot. The automation must explicitly use the customer managed KMS key, not the AWS managed key. Updating the AWS managed key policy is not possible in the required way because AWS managed keys are controlled by AWS.

Amazon S3 Lifecycle rules provide anative, fully managed mechanismto automatically transition or delete objects based on their age. According to the AWS Certified Security – Specialty Official Study Guide, S3 Lifecycle policies are therecommended and most secure methodfor enforcing data retention requirements because they operate automatically, consistently, and without custom code.

By configuring a lifecycle rule to delete objects after 45 days, the company ensures that sensitive datasets are retained long enough to support the 30-day model training process while remaining compliant with the data retention policy. Lifecycle rules are enforced by Amazon S3 itself and apply uniformly to all objects in the bucket or to objects that match specific prefixes or tags.

Option B and Option C introduce unnecessary operational complexity and risk by relying on custom Lambda code and scheduling. These approaches are more error-prone, harder to audit, and less reliable than a built-in S3 capability. Option D is incorrect because S3 Intelligent-Tiering manages storage cost optimization and does not delete data.

AWS documentation explicitly states thatS3 Lifecycle rules are the standard control for enforcing retention and deletion policies, particularly for sensitive data stored at scale.
