HashiCorp HashiCorp Certifications VA-002-P Questions & Answers

• Question 21:

  Complete the following sentence:

  The terraform state command can be used to ____

  A. view the entire state file

  B. modify the current state, such as removing items

  C. refresh the existing state

  D. there is no such command

  Correct Answer: B

  The terraform state command is used for advanced state management. Rather than modify the state directly, the terraform state commands can be used in many cases instead. https://www.terraform.io/docs/ commands/state/index.html

• Question 22:

  A user creates three workspaces from the command line - prod, dev, and test. Which of the following commands will the user run to switch to the dev workspace?

  A. terraform workspace select dev

  B. terraform workspace -switch dev

  C. terraform workspace dev

  D. terraform workspace switch dev

  Correct Answer: A

  The terraform workspace select command is used to choose a different workspace to use for further operations. https://www.terraform.io/docs/commands/workspace/select.html

• Question 23:

  In terraform, most resource dependencies are handled automatically. Which of the following statements describes best how terraform resource dependencies are handled?

  A. The terraform binary contains a built-in reference map of all defined Terraform resource dependencies. Updates to this dependency map are reflected in terraform versions. To ensure you are working with the latest resource dependency map you much be running the latest version of Terraform.

  B. Terraform analyses any expressions within a resource block to find references to other objects and treats those references as implicit ordering requirements when creating, updating, or destroying resources.

  C. Resource dependencies are identified and maintained in a file called resource. dependencies. Each terraform provider is required to maintain a list of all resource dependencies for the provider and it's included with the plugin during initialization when terraform init is executed. The file is located in the terraform.d folder.

  D. Resource dependencies are handled automatically by the depends_on meta_argument, which is set to true by default.

  Correct Answer: B

  Terraform analyses any expressions within a resource block to find references to other objects and treats those references as implicit ordering requirements when creating, updating, or destroying resources. https://www.terraform.io/docs/configuration/resources.html

• Question 24:

  A user has created a module called "my_test_module" and committed it to GitHub. Over time, several commits have been made with updates to the module, each tagged in GitHub with an incremental version number. Which of the following lines would be required in a module configuration block in terraform to select tagged version v1.0.4?

  A. source = "git::https://wpexpertsupport.com/my_test_module.git#tag=v1.0.4"

  B. source = "git::https://wpexpertsupport.com/my_test_module.git@tag=v1.0.4"

  C. source = "git::https://wpexpertsupport.com/my_test_module.git?ref=v1.0.4"

  D. source = "git::https://wpexpertsupport.com/my_test_module.gitandref=v1.0.4"

  Correct Answer: C

  By default, Terraform will clone and use the default branch (referenced by HEAD) in the selected repository. You can override this using the ref argument: module "vpc" {source = "git::https://wpexpertsupport.com/vpc.git?ref=v1.2.0"} The value of the ref argument can be any reference that would be accepted by the git checkout command, including branch and tag names. https://www.terraform.io/docs/modules/sources.html#selecting-a-revision

• Question 25:

  What is the result of the following terraform function call? index(["a", "b", "c"], "c") A. 1

  B. true

  C. 2

  D. 0

  Correct Answer: C

  index finds the element index for a given value in a list starting with index 0. https://www.terraform.io/docs/ configuration/functions/index.html

• Question 26:

  The following is a snippet from a Terraform configuration file:

  1.

  provider "aws" {

  2.

  region = "us-east-1"

  3.

  }

  4.

  provider "aws" {

  5.

  region = "us-west-1"

  6.

  }

  which, when validated, results in the following error:

  1.

  Error: Duplicate provider configuration

  2.

  3.

  on main.tf line 5:

  4.

  5: provider "aws" {

  5.

  6.

  A default provider configuration for "aws" was already given at

  7.

  main.tf:1,1-15. If multiple configurations are required, set the "______"

  8.

  argument for alternative configurations.

  Fill in the blank in the error message with the correct string from the list below.

  A. label

  B. version

  C. alias

  D. multi

  Correct Answer: C

  An alias meta-argument is used when using the same provider with different configurations for different resources. https://www.terraform.io/docs/configuration/providers.html#alias-multiple-provider-instances

• Question 27:

  When using providers that require the retrieval of data, such as the HashiCorp Vault provider, in what phase does Terraform actually retrieve the data required?

  A. terraform apply

  B. terraform plan

  C. terraform init

  D. terraform delete

  Correct Answer: B

  It is important to consider that Terraform reads from data sources during the plan phase and writes the result into the plan. For something like a Vault token which has an explicit TTL, the apply must be run before the data, or token, in this case, expires, otherwise, Terraform will fail during the apply phase.

• Question 28:

  A user has created three workspaces using the command line - prod, dev, and test. The user wants to create a fourth workspace named stage. Which command will the user execute to accomplish this?

  A. terraform workspace -new stage

  B. terraform workspace -create stage

  C. terraform workspace create stage

  D. terraform workspace new stage

  Correct Answer: D

  The terraform workspace new command is used to create a new workspace. https://www.terraform.io/ docs/commands/workspace/new.html

• Question 29:

  Terraform Enterprise (also referred to as pTFE) requires what type of backend database for a clustered deployment?

  A. Cassandra

  B. MSSQL

  C. PostgreSQL

  D. MySQL

  Correct Answer: C

  External Services mode stores the majority of the stateful data used by the instance in an external PostgreSQL database and an external S3-compatible endpoint or Azure blob storage. There are still critical data stored on the instance that must be managed with snapshots. Be sure to check the PostgreSQL Requirements for information that needs to be present for Terraform Enterprise to work. This option is best for users with expertise managing PostgreSQL or users that have access to managed PostgreSQL offerings like AWS RDS.

  A. unlock

  B. Removing the lock on a state file is not possible

  C. force-unlock

  D. state-unlock

  Correct Answer: C

  terraform force-unlock removes the lock on the state for the current configuration.
