Question
Company configures a landing zone in AWS Control Tower. The company handles sensitive data that must remain within the European Union. The company must use only the eu-central-1 Region. The company uses SCPs to enforce data residency policies. GenAI developers at the company are assigned IAM roles that have full permissions for Amazon Bedrock.
The company must ensure that GenAI developers can use the Amazon Nova Pro model through Amazon Bedrock only by using cross-Region inference (CRI) and only in eu-central-1. The company enables model access for the GenAI developer IAM roles in Amazon Bedrock. However, when a GenAI developer attempts to invoke the model through the Amazon Bedrock Chat/Text playground, the GenAI developer receives the following error.
User: arn:aws:sts::123456789012:assumed-role/AssumedDevRole/DevUserName
Action: bedrock:InvokeModelWithResponseStream
On resource(s): arn:aws:bedrock:eu-west-3::foundation-model/amazon.nova-pro-v1:0
Context: a service control policy explicitly denies the action
The company needs a solution to resolve the error. The solution must retain the company's existing governance controls and must provide precise access control. The solution must comply with the company's existing data residency policies.
Which combination of solutions will meet these requirements? (Choose two.)
- A. Add an AdministratorAccess policy to the GenAI developer IAM role.
- B. Extend the existing SCPs to enable CRI for the eu.amazon.nova-pro-v1:0 inference profile. Correct
- C. Enable Amazon Bedrock model access for Amazon Nova Pro in the eu-west-3 Region.
- D. Validate that the GenAI developer IAM roles have permissions to invoke Amazon Nova Pro through the eu.amazon.nova-pro.v1:0 inference profile on all European Union AWS Regions that can serve the model. Correct
- E. Extend the existing SCP to enable CRI for the eu.* inference profile.
Explanation
The correct answers are B and D because extending the existing Service Control Policies (SCPs) to explicitly allow cross-Region inference (CRI) for the specific model in option B ensures that data residency policies are maintained while allowing necessary access. Option D validates that IAM roles have permissions to invoke the Amazon Nova Pro model through the specified inference profile across all EU regions, ensuring precise access control and compliance with governance controls.
