Understanding Terraform import command behavior

What does the terraform import command do when executed?

A It adds an existing cloud resource to the Terraform state without modifying the resource.

B It creates the resource in the cloud provider based on the Terraform configuration.

C It deletes the resource from the cloud provider and removes it from the Terraform state.

D It updates the Terraform configuration files to match the existing cloud resource.

💡 Hint

Think about whether terraform import changes the actual cloud resource or just Terraform's knowledge of it.

The terraform import command links an existing resource in the cloud to Terraform's state file. It does not create, delete, or modify the resource itself, nor does it change configuration files.

❓ Configuration

Correct syntax for Terraform import command

Which of the following is the correct syntax to import an AWS S3 bucket named my-bucket into Terraform resource aws_s3_bucket.example?

A terraform import aws_s3_bucket.example aws_s3_bucket.my-bucket

B terraform import aws_s3_bucket.example bucket/my-bucket

C terraform import aws_s3_bucket.example my-bucket

D terraform import aws_s3_bucket.example s3://my-bucket

💡 Hint

Remember the format is terraform import <resource_type.resource_name> <resource_id>.

The correct syntax uses the resource address followed by the resource ID as recognized by the cloud provider. For S3 buckets, the bucket name alone is the ID.

Impact of importing resources on Terraform state and configuration

After importing an existing cloud resource into Terraform state using terraform import, what must you do to ensure Terraform manages the resource correctly in future runs?

A No further action is needed; Terraform automatically updates configuration files.

B Manually add the matching resource block to the Terraform configuration files.

C Delete the resource from the cloud and recreate it with Terraform.

D Run <code>terraform refresh</code> to update the configuration files automatically.

💡 Hint

Think about how Terraform knows what to manage after importing.

Importing only updates the state file. You must manually add the resource block in your configuration files so Terraform knows how to manage the resource in future plans and applies.

Security considerations when using Terraform import

Which security risk is most relevant when using terraform import to add existing cloud resources to Terraform state?

A Terraform import can expose sensitive resource data in the state file if not handled securely.

B Terraform import automatically grants admin permissions to all users.

C Terraform import deletes resource access policies during import.

D Terraform import disables encryption on imported resources.

💡 Hint

Consider what information Terraform state files contain and how they are stored.

Terraform state files can contain sensitive information about resources. Importing resources adds their data to the state file, so securing the state file is critical to prevent data leaks.

Behavior of Terraform import with resources having dependencies

You import a resource that depends on another resource not yet managed by Terraform. What happens when you run terraform plan after the import?

A Terraform will show no changes since the imported resource is in state.

B Terraform will fail with an error about missing dependencies.

C Terraform will automatically import the dependent resource as well.

D Terraform will plan to create the dependent resource since it is missing from the state.

💡 Hint

Think about how Terraform handles resources defined in configuration but not in state.

Terraform only manages resources defined in configuration and tracked in state. If a dependency is missing, Terraform plans to create it to satisfy dependencies.
