HashiCorp TERRAFORM-ASSOCIATE-003 Online Questions & Answers

• Question 421:

  When using a remote backend or terraform Cloud integration, where does Terraform save resource sate?

  A. In an environment variable
  B. On the disk
  C. In the remote backend or Terraform Cloud
  D. In memory
  C. In the remote backend or Terraform Cloud

  ---

  Explanation

  This is where Terraform saves resource state when using a remote backend or Terraform Cloud integration, as it allows you to store and manage your state file in a remote location, such as a cloud storage service or Terraform Cloud's servers. This enables collaboration, security, and scalability for your Terraform infrastructure.

• Question 422:

  You have configured an Auto Scaling group in AWS to automatically scale the number of instances behind a load balancer based on the instances CPU utilization. The instances are configured using a Launch Configuration. You have observed that the Auto Scaling group doesn't successfully scale when you apply changes that require replacing the Launch Configuration. Why is this happening?

  A. You need to configure an explicit dependency for the Auto Scaling group using the depends_on meta-parameter.
  B. You need to configure an explicit dependency for the Launch Configuration using the depends_on meta-parameter.
  C. You need to configure the Auto Scaling group's create_before_destroy meta-parameter.
  D. You need to configure the Launch Configuration's create_before_destroy meta-parameter.
  D. You need to configure the Launch Configuration's create_before_destroy meta-parameter.

• Question 423:

  After creating a new workspace "PROD" you need to run the command terraform select PROD to switch to it.

  A. False
  B. True
  A. False

  ---

  Explanation

  By default, when you create a new workspace you are automatically switched to it To create a new workspace and switch to it, you can use terraform workspace new ; to switch to a existing workspace you can use

  terraform workspace select ;

  Example:

  $ terraform workspace new example

  Created and switched to workspace "example"!

  You're now on a new, empty workspace. Workspaces isolate their state, so if you run "terraform plan" Terraform will not see any existing state for this configuration.

• Question 424:

  What is the standard workflow that a developer follows while working with terraform open source version?

  A. Run terraform refresh to update the terraform state , then write the terraform code , and finally run terraform apply.
  B. Run terraform destroy first since you need to start from fresh every time , before running terraform apply.
  C. Write terraform code , and run terraform push , to update the terraform state to the remote repo , which in turn will take care of the next steps.
  D. Write the terraform code on the developer machine , run terraform plan to check the changes , and run terraform apply to provision the infra.
  D. Write the terraform code on the developer machine , run terraform plan to check the changes , and run terraform apply to provision the infra.

  ---

  Explanation

  You do not need to run terraform refresh as terraform plan implicitly will run terraform refresh. https://www.terraform.io/guides/core-workflow.html

• Question 425:

  Select the most accurate statement to describe the Terraform language from the following list.

  A. Terraform is an immutable, declarative, Infrastructure as Code provisioning language based on Hashicorp Configuration Language, or optionally JSON.
  B. Terraform is a mutable, declarative, Infrastructure as Code configuration management language based on Hashicorp Configuration Language, or optionally JSON.
  C. Terraform is an immutable, procedural, Infrastructure as Code configuration management language based on Hashicorp Configuration Language, or optionally JSON.
  D. Terraform is a mutable, procedural, Infrastructure as Code provisioning language based on Hashicorp Configuration Language, or optionally YAML.
  A. Terraform is an immutable, declarative, Infrastructure as Code provisioning language based on Hashicorp Configuration Language, or optionally JSON.

  Explanation

  Terraform is not a configuration management tool-https://www.terraform.io/intro/vs/chefpuppet.html Terraform is a declarative language-https://www.terraform.io/docs/configuration/index.html Terraform supports a syntax that is JSON compatible-https://www.terraform.io/docs/configuration/syntax-json.html Terraform is primarily designed on immutable infrastructure principles-https://www.hashicorp.com/resources/what-is-mutable-vs-immutable-infrastructure

• Question 426:

  Terraform Enterprise currently supports running under which the following operating systems?

  A. Ubuntu
  B. Amazon Linux
  C. Debian
  D. CentOS
  E. Red Hat Enterprise Linux
  F. Oracle Linux
  A. Ubuntu
  B. Amazon Linux
  C. Debian
  D. CentOS
  E. Red Hat Enterprise Linux
  F. Oracle Linux

  ---

  Explanation

  A,B,C,D,E,F Terraform Enterprise runs on Linux instances, and you must prepare a running Linux instance for Terraform Enterprise before running the installer. You will start and manage this instance like any other server. Terraform Enterprise currently supports running under the following operating systems: Standalone deployment: Debian 7.7+ Ubuntu 14.04.5 / 16.04 / 18.04 Red Hat Enterprise Linux 7.4-7.8 CentOS 6.x / 7.4-7.8 Amazon Linux 2014.03 / 2014.09 / 2015.03 / 2015.09 / 2016.03 / 2016.09 / 2017.03 / 2017.09 / 2018.03 / 2.0 Oracle Linux 7.4-7.8 https://www.terraform.io/docs/enterprise/before-installing/index.html

• Question 427:

  Which of the following is available only in Terraform Enterprise or Cloud workspaces and not in Terraform CLI?

  A. Secure variable storage
  B. Support for multiple cloud providers
  C. Dry runs with terraform plan
  D. Using the workspace as a data source
  A. Secure variable storage

• Question 428:

  How would you output returned values from a child module in the Terraform CLI output?

  A. Declare the output in the root configuration
  B. Declare the output in the child module
  C. Declare the output in both the root and child module
  D. None of the above
  C. Declare the output in both the root and child module

  ---

  Explanation

  To output returned values from a child module in the Terraform CLI output, you need to declare the output in both the child module and the root module. The child module output will return the value to the root module, and the root module output will display the value in the CLI.

• Question 429:

  Which of these actions are forbidden when the Terraform state file is locked? (Pick the 3 correct responses)

  A. terraform apply
  B. terraform state list
  C. terraform destroy
  D. terraform fmt
  A. terraform apply
  B. terraform state list
  C. terraform destroy

  ---

  Explanation

  When the state file is locked, operations that modify or depend on the state (like terraform apply, terraform destroy, and terraform state list) are blocked. terraform fmt only formats the configuration files and does not interact with the state, so it

  is allowed.

• Question 430:

  You have been given requirements to create a security group for a new application. Since your organization standardizes on Terraform, you want to add this new security group with the fewest number of lines of code. What feature could you use to iterate over a list of required tcp ports to add to the new security group?

  A. dynamic backend
  B. splat expression
  C. terraform import
  D. dynamic block
  D. dynamic block

  ---

  Explanation

  A dynamic block acts much like a for expression, but produces nested blocks instead of a complex typed value. It iterates over a given complex value and generates a nested block for each element of that complex value. https://www.terraform.io/docs/configuration/expressions.html#dynamic-blocks
