AWS Cloud Development Kit - From Beginner to Professional - CDK Tokens: How to Export/Import Stack Values | Cfn Intrinsi

The video tutorial covers the use of CDK tokens, similar to CloudFormation intrinsic functions, in web applications. It explains how to create and export S3 buckets, validate and manipulate token values, and deploy stacks while checking for changes. The tutorial also discusses numerical validations and understanding runtime values in CDK.

What is a key similarity between CDK tokens and CloudFormation intrinsic functions?

• Both are used for frontend development.

• Both are used for database management.

• Both are used for backend server configuration.

• Both allow passing information between different stacks.

What is the purpose of defining a logical ID in CDK?

• To uniquely identify and export values from a stack.

• To identify the type of resource being created.

• To set the security policies for a resource.

• To specify the region of deployment.

What is the purpose of the 'cfan output' in CDK?

• To set the deployment region.

• To import values from other stacks.

• To define the security policies of a stack.

• To export values for use in other stacks.

Which of the following is NOT a type of value that a CDK token can represent?

• Boolean

• Number

• List

• String

What is the first step in creating a new bucket in CDK?

• Defining the bucket's location.

• Deploying the stack.

• Creating an object to store the bucket's value.

• Exporting the bucket's value.

What should you do if you encounter a duplicate logical ID error in CDK?

• Rename the logical ID to a unique name.

• Ignore the error and proceed.

• Restart the CDK application.

• Delete the existing resource.

What is the significance of the 'export name' in CDK?

• It determines the deployment region.

• It specifies the type of resource.

• It sets the security level of the resource.

• It allows other stacks to import the value.

How can you check the changes made to a stack before deployment in CDK?

• By reviewing the change set.

• By running a Python script.

• By exporting the stack.

• By checking the logical ID.

Why is it important to perform validations on CDK tokens?

• To ensure the tokens are not used in multiple stacks.

• To prevent tokens from being exported.

• To verify the tokens meet specific criteria before use.

• To ensure tokens are only used in Python code.

What happens to the bucket name at runtime in CDK?

• It is assigned a default value.

• It is set to a numerical identifier.

• It remains unresolved until deployment.

• It is automatically exported.
