Question 590
A release gate must account for this limitation while using: Apply a tested S3 bucket policy that enforces the required encryption conditions for the defined upload path. This relates to a situation where an ML data bucket must reject client uploads that do not request the approved server-side encryption mode even though S3 default encryption exists. Which limitation is most important when deciding whether this change is suitable?
- Secrets retrieval still requires secure logging and prevents no exposure if code prints the value.
- Granting S3 GetObject without necessary KMS permissions can still cause access denied.
- Private subnets without endpoints can break necessary S3, ECR, or logging access.
- Encryption policy condition handling must account for AWS-managed default encryption and client behavior.
Explanation
Correct Answer
D:This is a real operational limit for the described design: Encryption policy condition handling must account for AWS-managed default encryption and client behavior. The associated control is: Apply a tested S3 bucket policy that enforces the required encryption conditions for the defined upload path. Its intended result is: Noncompliant write requests fail before protected input data is stored. This limitation must still be managed.

Explanation
Correct Answer
A:This is a real operational limit for the described design: Granting S3 GetObject without necessary KMS permissions can still cause access denied. The associated control is: Encrypt model artifacts with a suitable KMS key and grant decryption only to approved roles.

Question 592
During risk sign-off, the team must assess this approved design step: Configure SageMaker jobs for restricted VPC networking with only approved endpoints and outbound paths. This relates to a situation where a hospital's training jobs should not call arbitrary public internet endpoints while reading private patient data. Which limitation is most important when deciding whether this change is suitable?

Question 593
A release gate must account for this limitation while using: Enable supported ECR image scanning and block promotion of artifacts with disallowed findings. This relates to a situation where an ML deployment pipeline pulls a custom container image containing a known vulnerable package and security wants the image rejected before production.

- Passing a vulnerability scan does not guarantee the runtime has no exploitable weaknesses.
- Least privilege must include legitimate output writes and KMS decrypt/encrypt operations as appropriate.
- Granting S3 GetObject without necessary KMS permissions can still cause access denied.
- Encryption policy condition handling must account for AWS-managed default encryption and client behavior.
Explanation
Correct Answer
A:This is a real operational limit for the described design: Passing a vulnerability scan does not guarantee the runtime has no exploitable weaknesses.
