HashiCorp HashiCorp Certifications TA-002-P Questions & Answers

• Question 181:

  You have modified your local Terraform configuration and ran terraform plan to review the changes. Simultaneously, your teammate manually modified the infrastructure component you are working on. Since you already ran terraform plan locally, the execution plan for terraform apply will be the same.

  A. True

  B. False

  Correct Answer: B

• Question 182:

  When writing Terraform code, HashiCorp recommends that you use how many spaces between each nesting level?

  A. 0

  B. 1

  C. 2

  D. 4

  Correct Answer: C

  The Terraform parser allows you some flexibility in how you lay out the elements in your configuration files, but the Terraform language also has some idiomatic style conventions which we recommend users always follow for consistency

  between files and modules written by different teams. Automatic source code formatting tools may apply these conventions automatically.

  Indent two spaces for each nesting level.

  When multiple arguments with single-line values appear on consecutive lines at the same nesting level, align their equals signs:

  ami = "abc123"

  instance_type = "t2.micro"

  When both arguments and blocks appear together inside a block body, place all of the arguments together at the top and then place nested blocks below them. Use one blank line to separate the arguments from the blocks. Use empty lines to

  separate logical groups of arguments within a block. For blocks that contain both arguments and "meta-arguments" (as defined by the Terraform language semantics), list meta-arguments first and separate them from other arguments with

  one blank line. Place meta-argument blocks last and separate them from other blocks with one blank line.

  resource "aws_instance" "example" {

  count = 2 # meta-argument first

  ami = "abc123"

  instance_type = "t2.micro"

  network_interface {

  # ...

  }

  lifecycle { # meta-argument block last

  create_before_destroy = true

  }

  }

  Top-level blocks should always be separated from one another by one blank line. Nested blocks should also be separated by blank lines, except when grouping together related blocks of the same type (like multiple provisioner blocks in a

  resource). Avoid separating multiple blocks of the same type with other blocks of a different type, unless the block types are defined by semantics to form a family. (For example:

  root_block_device, ebs_block_device and ephemeral_block_device on aws_instance form a family of block types describing AWS block devices, and can therefore be grouped together and mixed.)

• Question 183:

  Which of the following statements about local modules is incorrect:

  A. Local modules are not cached by terraform init command

  B. Local modules are sourced from a directory on disk

  C. Local modules support versions

  D. All of the above (all statements above are incorrect

  E. None of the above (all statements above are correct)

  Correct Answer: C

  Version constraints are supported only for modules installed from a module registry, such as the public Terraform Registry or Terraform Cloud's private module registry. Other module sources can provide their own versioning mechanisms within the source string itself, or might not support versions at all. In particular, modules sourced from local file paths do not support version; since they're loaded from the same source repository, they always share the same version as their caller. https://www.terraform.io/language/modules/syntax

• Question 184:

  How would you reference the Volume IDs associated with the ebs_block_device blocks in this configuration?

  

  A. aws_instance.example.ebs_block_device.[*].volume_id

  B. aws_instance.example.ebs_block_device.volume_id

  C. aws_instance.example.ebs_block_device[sda2,sda3].volume_id

  D. aws_instance.example.ebs_block_device.*.volume_id

• Question 186:

  Terraform is currently being used by your organisation to create resources on AWS for the development of a web application. One of your coworkers wants to change the instance type to "t2.large" while keeping the default set values. What adjustments does the teammate make in order to meet his goal?

  A. Issue Terraform plan instance.type".t2.large" and it deploys the instance

  B. Modify the tf.variableswith the instance type and issue terraform apply

  C. Create a new file my.tfvars and add the type of the instance and issue terraform plan and apply

  D. Modify the terraform.tfvars with the instance type and issue terraform plan and then terraform apply to deploy the instances

  Correct Answer: D

• Question 187:

  You're writing a Terraform configuration that needs to read input from a local file called id_rsa.pub. Which built-in Terraform function can you use to import the file's contents as a string?

  A. fileset("id_rsa.pub")

  B. filebase64("id_rsa.pub")

  C. templatefile("id_rsa.pub")

  D. file("id_rsa.pub")

  Correct Answer: D

• Question 188:

  Do terraform workspaces help in adding/allowing multiple state files for a single configuration?

  A. True

  B. False

  Correct Answer: A

• Question 189:

  To check if all code in a Terraform configuration with multiple modules is properly formatted without making changes, what command should be run?

  A. terraform fmt-check

  B. terraform fmt-write-false

  C. terraform fmt "list-recursive

  D. terraform fmt-check-recursive

  Correct Answer: D

  -check Check if the input is formatted. Exit status will be 0 if all input is properly formatted and non-zero otherwise.-recursive Also process files in subdirectories. By default, only the given directory (or current directory) is processed.
