HashiCorp TERRAFORM-ASSOCIATE-003 Online Questions & Answers

• Question 1:

  If a DevOps team adopts AWS Cloud Formation as their standardized method for provisioning public cloud resoruces, which of the following scenarios poses a challenge for this team?

  A. The team is asked to manage a new application stack built on AWS-native services
  B. The organization decides to expand into Azure wishes to deploy new infrastructure
  C. The team is asked to build a reusable code based that can deploy resources into any AWS region
  D. The DevOps team is tasked with automating a manual, web console-based provisioning.
  B. The organization decides to expand into Azure wishes to deploy new infrastructure

  ---

  explanation:

  Explanation

  This is the scenario that poses a challenge for this team, if they adopt AWS CloudFormation as their standardized method for provisioning public cloud resources, as CloudFormation only supports AWS services and resources, and cannot be used to provision infrastructure on other cloud platforms such as Azure.

• Question 2:

  Which of these actions will prevent two Terraform runs from changing the same state file at the same time?

  A. Refresh the state after running Terraform
  B. Delete the state before running Terraform
  C. Configure state locking for your state backend
  D. Run Terraform with parallelism set to 1
  B. Delete the state before running Terraform

  ---

  explanation:

  Explanation

  To prevent two Terraform runs from changing the same state file simultaneously, state locking is used. State locking ensures that when one Terraform operation is running, others will be blocked from making changes to the same state, thus preventing conflicts and data corruption. This is achieved by configuring the state backend to support locking, which will lock the state for all operations that could write to the state.

  References: This information is supported by Terraform's official documentation, which explains the importance of state locking and how it can be configured for different backends to prevent concurrent state modifications .

• Question 3:

  You must use different Terraform commands depending on the cloud provider you use.

  A. True
  B. False
  B. False

  ---

  explanation:

  Explanation

  You do not need to use different Terraform commands depending on the cloud provider you use. Terraform commands are consistent across different providers, as they operate on the Terraform configuration files and state files, not on the provider APIs directly.

• Question 4:

  Which of these ate features of Terraform Cloud? Choose two correct answers.

  A. Automated infrastructure deployment visualization
  B. Automatic backups
  C. A web-based user interface (Ul)
  D. Remote state storage
  C. A web-based user interface (Ul)
  D. Remote state storage

  ---

  explanation:

  Explanation

  These are features of Terraform Cloud, which is a hosted service that provides a web- based UI, remote state storage, remote operations, collaboration features, and more for managing your Terraform infrastructure.

• Question 5:

  Which of the following is not a valid siring function in Terraform?

  A. choaf
  B. join
  C. Split
  D. slice
  A. choaf

  ---

  explanation:

  Explanation

  This is not a valid string function in Terraform. The other options are valid string functions that can manipulate strings in various ways2.

• Question 6:

  What is terraform refresh-only intended to detect?

  A. Terraform configuration code changes
  B. Corrupt state files
  C. State file drift
  D. Empty state files
  C. State file drift

  ---

  explanation:

  Explanation

  The terraform refresh-only command is intended to detect state file drift. This command synchronizes the state file with the actual infrastructure, updating the state to reflect any changes that have occurred outside of Terraform.

• Question 7:

  Which command lets you experiment with terraform expressions?

  A. Terraform console
  B. Terraform validate
  C. Terraform env
  D. Terraform test
  A. Terraform console

  ---

  explanation:

  Explanation

  This is the command that lets you experiment with Terraform expressions, by providing an interactive console that allows you to evaluate expressions and see their results. You can use this command to test your expressions before using them in your configuration files.

• Question 8:

  You are writing a child Terraform module that provisions an AWS instance. You want to reference the IP address returned by the child module in the root configuration. You name the instance resource "main'.

  Which of these is the correct way to define the output value?

  

  A. Option A
  B. Option B
  C. Option C
  D. Option D
  A. Option A

  ---

  explanation:

  Explanation

  output "name-rg" { value = azurerm_resource_group.example.name }

  output "name-rg2" { value = "${azurerm_resource_group.example.name}" }

  Changes to Outputs:

  +

  name-rg = "example-resource-group"

  +

  name-rg2 = "example-resource-group"

• Question 9:

  terraform validate confirms that your infrastructure matches the Terraform state file.

  A. True
  B. False
  B. False

  ---

  explanation:

  Explanation

  terraform validate does not confirm that your infrastructure matches the Terraform state file. It only checks whether the configuration files in a directory are syntactically valid and internally consistent3. To confirm that your infrastructure matches the Terraform state file, you need to use terraform plan or terraform apply with the -refresh-only option.

• Question 10:

  Which command add existing resources into Terraform state?

  A. Terraform init
  B. Terraform plan
  C. Terraform refresh
  D. Terraform import
  E. All of these
  D. Terraform import

  ---

  explanation:

  Explanation

  This is the command that can add existing resources into Terraform state, by matching them with the corresponding configuration blocks in your files.
