AWS Certified CloudOps Engineer Associate SOA-C03 Practice Question

Your company manages infrastructure for multiple AWS accounts using Terraform. You must build a CI/CD pipeline that: validates plans on every commit, stores Terraform state centrally with locking to prevent simultaneous writes, and avoids long-lived credentials in the pipeline environment. Which approach meets these requirements while following AWS and Terraform best practices?

  • Configure an encrypted, versioned S3 bucket with a DynamoDB table for state locking; have CodeBuild assume an environment-specific IAM role via STS and run Terraform with the S3 backend.

  • Wrap Terraform modules in CloudFormation StackSets and use CloudFormation as the remote backend; pass cross-account role ARNs to CodePipeline through environment variables.

  • Use the local backend on the CodeBuild container and rely on CodePipeline artifact versioning; create a single IAM user with AdministratorAccess and embed its access keys in the buildspec file.

  • Store the state file in a CodeCommit repository and enable repository versioning; store each account's access keys in Secrets Manager and inject them into the build environment.
