Exam AWS Certified Advanced Networking - Specialty ANS-C01 topic 1 question 145 discussion

Exam question from Amazon's AWS Certified Advanced Networking - Specialty ANS-C01
Question #: 145
Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

A team of infrastructure engineers wants to automate the deployment of Application Load Balancer (ALB) components by using the AWS Cloud Development Kit (AWS CDK). The CDK application must deploy an infrastructure stack that is reusable and consistent across multiple environments, AWS Regions, and AWS accounts.

The lead network architect on the project has already bootstrapped the target accounts. The lead network architect also has deployed core network components such as VPCs and Amazon Route 53 private hosted zones across the multiple environments and Regions. The infrastructure engineers must design the ALB components in the CDK application to use the existing core network components.

Which combination of steps will meet this requirement with the LEAST manual effort between environment deployments? (Choose two.)

  • A. Design the CDK application to read AWS CloudFormation parameters for the values that vary across environments and Regions. Reference these variables in the CDK stack for resources that require the variables.
  • B. Design the CDK application to read environment variables that contain account and Region details at runtime. Use these variables as properties of the CDK stack. Use context methods in the CDK stack to retrieve variable values.
  • C. Create a dedicated account for shared application services in the multi-account environment. Deploy a CDK pipeline to the dedicated account. Create stages in the pipeline that deploy the CDK application across different environments and Regions.
  • D. Write a script that automates the deployment of the CDK application across multiple environments and Regions. Distribute the script to engineers who are working on the project.
  • E. Use the CDK toolkit locally to deploy stacks to each environment and Region. Use the --context flag to pass in variables that the CDK application can reference at runtime.

BC. https://docs.aws.amazon.com/cdk/v2/guide/environments.html you can use environment variables to pass in values that vary across environments and Regions. You can use the --context flag when running cdk deploy to set environment variables for the CDK application. You can also use the CDK_DEFAULT_ACCOUNT and CDK_DEFAULT_REGION environment variables provided by the AWS CDK CLI to specify the target account and Region for deployment.

By utilizing AWS CloudFormation parameters for environment-specific values and setting up a CDK pipeline, you can achieve a consistent deployment across multiple environments and Regions with minimal manual effort.

In general, we recommend AGAINST using AWS CloudFormation parameters with the AWS CDK. https://docs.aws.amazon.com/cdk/v2/guide/parameters.html

Something to review for option A In general, we recommend against using AWS CloudFormation parameters with the AWS CDK. The usual ways to pass values into AWS CDK apps are context values and environment variables. Because they are not available at synthesis time, parameter values cannot be easily used for flow control and other purposes in your CDK app.

I think should be AC, the concern I have is A - you can use AWS CloudFormation outputs to read parameters across stacks in the same Region, but you can’t do this across Regions
