This domain is part of the AWS Certified DevOps Engineer Professional practice test. Each question is tagged by exam objective and difficulty so you can drill exactly the areas you need.

Sample Questions

A platform team wants every application stack to define resources, dependencies, parameters, and exported values in a repeatable way. Which CloudFormation design should be used?
  • A. A version-controlled template with Resources, Parameters, Outputs, and explicit dependencies where needed
  • B. A runbook that asks operators to create resources in console order
  • C. A plain text checklist stored with no resource definitions
  • D. A single unmanaged JSON file containing only resource names

A complete template makes the stack reproducible and lets CloudFormation understand resource creation order, configuration inputs, and values exported to other stacks. This is the correct answer.

A CloudFormation template must expose a database endpoint to a dependent application stack. What template section supports this?
  • A. Outputs with an export or a consumed stack output pattern
  • B. Mappings only
  • C. Conditions only
  • D. Metadata only

Outputs publish useful values after stack creation, and exports can allow other stacks to reference them. This is the correct answer.

A team repeatedly copies the same VPC resources into many templates and mistakes are increasing. Which IaC component pattern should reduce duplication?
  • A. Copy and paste the VPC resources into every template release
  • B. Reusable nested stacks or modules for the common VPC pattern
  • C. Create the VPC manually and omit it from version control
  • D. Use stack outputs as the only definition of the VPC

Reusable components keep shared infrastructure definitions consistent while allowing teams to pass environment-specific inputs. This is the correct answer.

A company wants a reusable template component but also wants teams to control allowed input values. What should be included?
  • A. Hardcoded production values in every property
  • B. Parameters with constraints and defaults where appropriate
  • C. Unconstrained free-form parameters for every security setting
  • D. Outputs that ask users to type values during rollback

Parameter constraints restrict valid inputs and defaults improve usability without hardcoding every environment value. This is the correct answer.

A team uses Terraform for some infrastructure but must deploy CloudFormation StackSets for AWS-managed account baselines. What is the DevOps concern?
  • A. Let every tool update every resource whenever it detects drift
  • B. Use each IaC tool with clear ownership boundaries to avoid conflicting resource management
  • C. Disable all state and drift tracking because two tools are present
  • D. Convert all infrastructure changes into manual console steps

Multiple IaC tools can coexist when ownership is explicit and the same resource is not managed by competing systems. This is the correct answer.

A CloudFormation template creates an Auto Scaling group and an Application Load Balancer target group. The group should not launch instances until the target group exists. What should the template use if implicit references are insufficient?
  • A. A random sleep command in a developer laptop script
  • B. A resource tag named CreateAfter
  • C. DependsOn or references that express the resource dependency
  • D. A longer stack name

Dependency declarations or intrinsic references help CloudFormation order creation when one resource depends on another being ready. This is the correct answer.

A team wants to model AWS infrastructure in TypeScript and synthesize CloudFormation templates in a pipeline. Which framework is most appropriate?
  • A. AWS CodeArtifact
  • B. AWS CodeDeploy AppSpec only
  • C. AWS CDK
  • D. Amazon ECR lifecycle policy

AWS CDK lets teams define cloud infrastructure in programming languages and synthesize CloudFormation templates. This is the correct answer.

A security team wants infrastructure templates to be reviewed like application code. What template management practice is best?
  • A. Allow operators to edit live stack resources directly for speed
  • B. Store the only template copy in a local downloads folder
  • C. Recreate templates from CloudTrail after each release
  • D. Keep templates in version control and require pull request review before deployment

Version control and review provide change history, peer review, and a controlled path into deployment pipelines. This is the correct answer.
