HashiCorp HashiCorp Certifications TA-002-P Questions & Answers

• Question 361:

  You have a simple Terraform configuration containing one virtual machine (VM) in a cloud provider. You run terraform apply and the VM is created successfully. What will happen if you delete the VM using the cloud provider console, and run terraform apply again without changing any Terraform code?

  A. Terraform will remove the VM from state file

  B. Terraform will report an error

  C. Terraform will not make any changes

  D. Terraform will recreate the VM

  Correct Answer: D

• Question 362:

  A provider configuration block is required in every Terraform configuration. Example:

  

  A. True

  B. False

  Correct Answer: B

  Unlike many other objects in the Terraform language, a provider block may be omitted if its contents would otherwise be empty. Terraform assumes an empty default configuration for any provider that is not explicitly configured. https://www.terraform.io/language/providers/configuration

• Question 363:

  You need to constrain the GitHub provider to version 2.1 or greater.

  Which of the following should you put into the Terraform 0.12 configuration's provider block?

  A. version >= 2.1

  B. version ~> 2.1

  C. version = "<= 2.1"

  D. version = ">= 2.1"

  Correct Answer: D

  version = ">= 1.2.0, < 2.0.0"

  A version constraint is a string literal containing one or more conditions, which are separated by commas.

  Each condition consists of an operator and a version number.

  Version numbers should be a series of numbers separated by periods (like 1.2.0), optionally with a suffix to indicate a beta release.

  The following operators are valid:

  = (or no operator): Allows only one exact version number. Cannot be combined with other conditions.

  !=: Excludes an exact version number.

  >, >=, <, <=: Comparisons against a specified version, allowing versions for which the comparison is true. "Greater-than" requests newer versions, and "less-than" requests older versions.

  ~>: Allows only the rightmost version component to increment. For example, to allow new patch releases within a specific minor release, use the full version number: ~> 1.0.4 will allow installation of 1.0.5 and 1.0.10 but not 1.1.0. This is

  usually called the pessimistic constraint operator.

• Question 364:

  What value does the Terraform Cloud/Terraform Enterprise private module registry provide over the public Terraform Module Registry?

  A. The ability to share modules with public Terraform users and members of Terraform Enterprise Organizations

  B. The ability to tag modules by version or release

  C. The ability to restrict modules to members of Terraform Cloud or Enterprise organizations

  D. The ability to share modules publicly with any user of Terraform

  Correct Answer: C

  Terraform Cloud's private registry works similarly to the public Terraform Registry and helps you share Terraform providers and Terraform modules across your organization. It includes support for versioning and a searchable list of available providers and modules.

• Question 365:

  Which statement describes a goal of infrastructure as code?

  A. An abstraction from vendor specific APIs

  B. Write once, run anywhere

  C. A pipeline process to test and deliver software

  D. The programmatic configuration of resources

  Correct Answer: D

  The purpose of infrastructure as code is to enable developers or operations teams to automatically manage, monitor and provision resources, rather than manually configure discrete hardware devices and operating systems. Infrastructure as code is sometimes referred to as programmable or software-defined infrastructure.

• Question 366:

  Which of the following is the correct way to pass the value in the variable num_servers into a module with the input servers?

  A. servers = num_servers

  B. servers = variable.num_servers

  C. servers = var(num_servers)

  D. servers = var.num_servers

  Correct Answer: D

  "Within the module that declared a variable, its value can be accessed from within expressions as var., where matches the label given in the declaration block: Note: Input variables are created by a variable block, but you reference them as attributes on an object named var." https://www.terraform.io/language/values/variables#using-input-variable-values

• Question 367:

  Which two steps are required to provision new infrastructure in the Terraform workflow? (Choose two.)

  A. Destroy

  B. Apply

  C. Import

  D. Init

  E. Validate

  Correct Answer: BD

  Reference: https://www.terraform.io/guides/core-workflow.html

• Question 368:

  A fellow developer on your team is asking for some help in refactoring their Terraform code. As part of their application's architecture, they are going to tear down an existing deployment managed by Terraform and deploy new. However, there is a server resource named aws_instance.ubuntu[1] they would like to keep to perform some additional analysis.

  What command should be used to tell Terraform to no longer manage the resource?

  A. terraform apply rm aws_instance.ubuntu[1]

  B. terraform state rm aws_instance.ubuntu[1]

  C. terraform plan rm aws_instance.ubuntu[1]

  D. terraform delete aws_instance.ubuntu[1]

  Correct Answer: B

  "You can use terraform state rm in the less common situation where you wish to remove a binding to an existing remote object without first destroying it, which will effectively make Terraform "forget" the object while it continues to exist in the remote system."

• Question 369:

  Setting the TF_LOG environment variable to DEBUG causes debug messages to be logged into syslog.

  A. True

  B. False

  Correct Answer: B

  TF_LOG_PATH IS NOT REQUIRED, in the docs, they do not mention HAVE TO SET TF_LOG_PATH, it is optional, therefore without TF_LOG_PATH will cause detailed logs to appear on stderr. https://www.computerhope.com/jargon/s/stderr.htm#:~:text=Stderr%2C%20also%20known %20as%20standard,defaults%20to%20the%20user's%20screen.

• Question 370:

  What is the provider for this fictitious resource?

  

  A. vpc

  B. main

  C. aws

  D. test

  Correct Answer: C
