Sample Questions

Question #132 / 529

A company manages multiple AWS accounts using AWS Organizations. The root OU contains two OUs: Development and Production.

Due to compliance requirements, all resources in the organization must be deployed in the us-west-2 Region. Additionally, RDS instances in the Production OU must use a predefined set of database instance classes.

A solutions architect must implement a solution that enforces these restrictions while maximizing operational efficiency and minimizing ongoing maintenance.

Which combination of steps will meet these requirements? (Choose two.)

A

Create an IAM role in one account under the Production OU. Use the rds:DBInstanceClass condition key in an inline policy on the role to restrict access to specific instance classes.

B

Create an IAM user in all accounts under the root OU. Use the aws:RequestedRegion condition key in an inline policy on each user to restrict access to all AWS Regions except us-west-2.

C

Create an SCP. Use the aws:RequestedRegion condition key to deny access to all AWS Regions except us-west-2. Apply the SCP to the root OU.

D

Create an SCP. Use the rds:Region condition key to restrict access to all AWS Regions except us-west-2. Apply the SCP to the root OU, Development OU, and Production OU.

E

Create an SCP. Use the rds:DBInstanceClass condition key to restrict access to specific database instance classes. Apply the SCP to the Production OU.

Question #493 / 529

A company is using AWS SAM for deploying serverless applications. All application code and templates are stored in Amazon S3 buckets with versioning enabled. Developers access an Amazon EC2 instance hosting a cloud-based IDE. They download code from S3, make changes, run unit tests locally, and upload the modified code back to S3. The team aims to enhance their deployment process by adopting CI/CD with AWS CodePipeline.

The developers must meet these requirements:

- Utilize AWS CodeCommit for source control.

- Automate unit testing and security checks.

- Notify developers immediately if unit tests fail.

- Dynamically toggle application features and customize deployments within the CI/CD pipeline.

- Require approval from the lead developer prior to production deployment.

Which solution fulfills these requirements?

A

Use AWS CodeBuild to automate unit tests and security scans. Configure an Amazon EventBridge rule to trigger Amazon SNS notifications when tests fail. Implement AWS CDK constructs with a feature toggle manifest file to enable/disable features dynamically. Include a manual approval step in the pipeline for the lead developer's review before deployment.

B

Use AWS Step Functions to orchestrate unit tests and security scans. Use Amazon CloudWatch Logs to detect test failures and send alerts via Amazon SES. Deploy feature toggles using AWS CloudFormation parameters and conditions. Integrate an Amazon SQS queue for the lead developer to approve deployments asynchronously.

C

Use AWS Lambda functions to execute unit tests and security scans. Configure an Amazon CloudWatch Events rule to send alerts via Amazon SNS upon test failures. Manage feature toggles using AWS Systems Manager Parameter Store and update parameters during deployment. Use AWS CodeDeploy hooks for the lead developer's approval.

D

Use Jenkins pipelines within AWS to run unit tests and security scans. Trigger Amazon SNS alerts via AWS CLI commands in the pipeline when tests fail. Implement feature flags using Amazon DynamoDB and custom scripts. Require the lead developer to approve deployments via an Amazon API Gateway endpoint.
