TERRAFORM-003 Practice Questions

Master the Understand Infrastructure as Code (IaC) concepts Domain

Test your knowledge in the Understand Infrastructure as Code (IaC) concepts domain with these 5 practice questions. Each question is designed to help you prepare for the TERRAFORM-003 certification exam with detailed explanations to reinforce your learning.

Question 1

Your Terraform configuration includes a module for creating Azure storage accounts. You want to ensure that the module version is consistent across environments. Which approach should you take?

A) Use a `version` argument in the module block to pin the module version.

B) Use the `terraform init -upgrade` command to always use the latest version.

C) Use `terraform fmt` to format the configuration files.

D) Use a `for_each` loop to iterate over module versions.

Show Answer & Explanation

Correct Answer: A

Explanation: Option A is correct because specifying a `version` argument in the module block ensures consistency across environments. Option B is incorrect as `terraform init -upgrade` updates to the latest version, which doesn't guarantee consistency. Option C is incorrect as `terraform fmt` only formats files. Option D is incorrect because `for_each` is used for iterating over resources, not versions.

Question 2

You are tasked with importing existing cloud resources into your Terraform state. Which of the following steps is necessary when using the `import` block in Terraform 1.x?

A) Run `terraform init -reconfigure` to prepare the configuration for importing.

B) Use the `terraform plan -replace=` command before importing.

C) Define the resource configuration in a `.tf` file before using the `import` block.

D) Ensure the backend supports state locking before using the `import` block.

Show Answer & Explanation

Correct Answer: C

Explanation: Before using the `import` block to import existing resources into Terraform, you must define the resource configuration in a `.tf` file. This allows Terraform to understand how the resource should be managed once it's imported. `terraform init -reconfigure` is used to reconfigure the backend, `terraform plan -replace=` is used to force a resource to be recreated, and state locking is a backend feature that is not directly related to the `import` block.

Question 3

You are managing infrastructure for a multi-cloud application using Terraform 1.x. You have an existing resource in AWS that was manually created, and you want to bring it under Terraform management without recreating it. How can you achieve this using Terraform's modern workflows?

A) Use the `terraform import` command with the resource address and ID.

B) Add the resource to your configuration and run `terraform apply -replace=`.

C) Use an `import {}` block in your configuration to specify the resource and run `terraform apply`.

D) Create a `moved` block to transition the resource into your Terraform state.

Show Answer & Explanation

Correct Answer: C

Explanation: To bring an existing resource under Terraform management without recreating it, you can use the `import {}` block in your configuration. This allows you to specify the resource type, name, and ID directly in your HCL files, making it part of your infrastructure as code. Option A is a legacy method that uses the CLI directly but doesn't integrate with the configuration files. Option B is incorrect because `-replace` is used to force recreation, not import. Option D is incorrect because `moved` blocks are used for renaming or relocating resources within the configuration, not for importing existing ones.

Question 4

You are managing infrastructure using Terraform for a multi-cloud project. You need to ensure that certain resources are not accidentally destroyed during a `terraform apply`. Which Terraform feature should you use to prevent such actions?

A) Use `prevent_destroy` in the `lifecycle` block of the resource.

B) Use `ignore_changes` in the `lifecycle` block of the resource.

C) Use `depends_on` to manage dependencies between resources.

D) Use `count` to conditionally create resources.

Show Answer & Explanation

Correct Answer: A

Explanation: The `prevent_destroy` argument within the `lifecycle` block is used to prevent a resource from being destroyed by Terraform. This is useful for critical resources that should not be accidentally deleted. `ignore_changes` is used to ignore changes to specific attributes, `depends_on` manages resource dependencies, and `count` is used for conditional resource creation.

Question 5

You are tasked with importing existing cloud resources into Terraform management. Which modern Terraform feature should you use to simplify this process?

A) Import blocks

B) Resource targeting

C) Remote operations

D) Variable validation

Show Answer & Explanation

Correct Answer: A

Explanation: Import blocks in Terraform 1.x allow you to define import operations directly in your configuration. This simplifies the process of bringing existing resources under Terraform management by specifying the import details in a structured way. Resource targeting, remote operations, and variable validation do not directly relate to importing resources.
