  C. The local backend is the directory where resources deployed by Terraform have direct access to in order to update their current state.

  D. The local backend is how Terraform connects to public cloud services, such as AWS, Azure, or GCP.

  Correct Answer: B

  The local backend stores state on the local filesystem, locks that state using system APIs, and performs operations locally.

• Question 334:

  You have created a custom variable definition file testing.tfvars. How will you use it for provisioning infrastructure?

  A. terraform apply-var-state-file ="testing.tfvars"

• Question 335:

  Which of the following Terraform files should be ignored by Git when committing code to a repo? (select Three)

  A. Files named exactly terraform.tfvars or terraform.tfvars.json.

  B. Any files with names ending in .auto.tfvars or .auto.tfvars.json.

  C. input.tf

  D. terraform.tfstate

  E. output.tf

  Correct Answer: ABD

  The .gitignore file should be configured to ignore Terraform files that either contain sensitive data or are not required to save. Terraform state (terraform.tfstate) can contain sensitive data, depending on the resources in use and your definition of "sensitive." The state contains resource IDs and all resource attributes. For resources such as databases, this may contain initial passwords. When using local state, state is stored in plain-text JSON files. The terraform.tfvars file may contain sensitive data, such as passwords or IP addresses of an environment that you may not want to share with others.

• Question 336:

  Which of the following command can be used to view the specified version constraints for all providers used in the current configuration.

  A. terraform providers

  B. terraform state show

  C. terraform provider

  D. terraform plan

  Correct Answer: A

  Use the terraform providers command to view the specified version constraints for all providers used in the current configuration. https://www.terraform.io/docs/configuration/providers.html

• Question 337:

  terraform refresh will update the state file?

  A. True

  B. False

  Correct Answer: A

  The terraform refresh command is used to reconcile the state Terraform knows about (via its state file) with the real-world infrastructure. This can be used to detect any drift from the last-known state, and to update the state file. This does not modify infrastructure, but does modify the state file. If the state is changed, this may cause changes to occur during the next plan or apply.

• Question 338:

  Which one of the following command will rewrite Terraform configuration files to a canonical format and style.

  A. terraform graph-h

  B. terraform init

  C. terraform graph

  D. terraform fmt

  Correct Answer: D

  The terraform fmt command is used to rewrite Terraform configuration files to a canonical format and style. This command applies a subset of the Terrra Terraform language style conventions, along with other minor adjustments for readability.
