What does the command terraform fmt do?
Options:
Answer: A Explanation: Explanation: The terraform fmt command is used to rewrite Terraform configuration files to a canonical format and style. This command applies a subset of the Terraform language style conventions, along with other minor adjustments for readability.Other Terraform commands that generate Terraform configuration will produce configuration files that conform to the style imposed by terraform fmt, so using this style in your own files will ensure consistency.https://www.terraform.io/docs/commands/fmt.htmm

Options:
Answer: A Explanation: Explanation: You may see this QUESTION NO: in actual exam. Please remember : Terraform does not require GO language to be installed as a prerequisite and it does not require a Windows Server as well.
HashiCorp TA-002-P Sample Question 11
You have declared a variable name my_var in terraform configuration without a value associated with it. variable my_var {} After running terraform plan it will show an error as variable is not defined.
Options:
Answer: B Explanation: Explanation: Input variables are usually defined by stating a name, type and a default value. However, the type and default values are not strictly necessary. Terraform can deduct the type of the variable from the default or input value.Variables can be predetermined in a file or included in the command-line options. As such, the simplest variable is just a name while the type and value are selected based on the input.variable "variable_name" {}terraform apply -var variable_name="value"The input variables, like the one above, use a couple of different types: strings, lists, maps, and boolean. Here are some examples of how each type are defined and used.StringStrings mark a single value per structure and are commonly used to simplify and make complicated values more user-friendly. Below is an example of a string variable definition.variable "template" {type = stringdefault = "01000000-0000-4000-8000-000030080200"}A string variable can then be used in resource plans. Surrounded by double quotes, string variables are a simple substitution such as the example underneath.storage = var.templateListAnother type of Terraform variables lists. They work much like a numbered catalogue of values. Each value can be called by their corresponding index in the list. Here is an example of a list variable definition.variable "users" {type = listdefault = ["root", "user1", "user2"]}Lists can be used in the resource plans similarly to strings, but youâll also need to denote the index of the value you are looking for.username = var.users[0]MapMaps are a collection of string keys and string values. These can be useful for selecting values based on predefined parameters such as the server configuration by the monthly price.variable "plans" {type = mapdefault = {"5USD" = "1xCPU-1GB""10USD" = "1xCPU-2GB""20USD" = "2xCPU-4GB"}}You can access the right value by using the matching key. For example, the variable below would set the plan to "1xCPU-1GB".plan = var.plans["5USD"]The values matching to their keys can also be used to look up information in other maps. For example, underneath is a shortlist of plans and their corresponding storage sizes.variable "storage_sizes" {type = mapdefault = {"1xCPU-1GB" = "25""1xCPU-2GB" = "50""2xCPU-4GB" = "80"}}These can then be used to find the right storage size based on the monthly price as defined in the previous example.size = lookup(var.storage_sizes, var.plans["5USD"])BooleanThe last of the available variable type is boolean. They give the option to employ simple true or false values. For example, you might wish to have a variable that decides when to generate the root user password on a new deployment.variable "set_password" {default = false}The above example boolean can be used similarly to a string variable by simply marking down the correct variable.create_password = var.set_passwordBy default, the value is set to false in this example. However, you can overwrite the variable at deployment by assigning a different value in a command-line variable.terraform apply -var set_password="true"
HashiCorp TA-002-P Sample Question 12
Which of the following Terraform files should be ignored by Git when committing code to a repo? (select Three)
Options:
Answer: A, B, D Explanation: Explanation: 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.
HashiCorp TA-002-P Sample Question 13

HashiCorp TA-002-P Sample Question 15
The current implementation of Terraform import can only import resources into the state. It does not generate configuration.
Options:
Answer: B Explanation: Explanation: The current implementation of Terraform import can only import resources into the state. It does not generate configuration. A future version of Terraform will also generate configuration.Because of this, prior to running terraform import it is necessary to write manually a resource configuration block for the resource, to which the imported object will be mapped.While this may seem tedious, it still gives Terraform users an avenue for importing existing resources.https://www.terraform.io/docs/import/index.html#currently-state-onlz

HashiCorp TA-002-P Sample Question 18
Which of the following best describes a Terraform provider?
Options:
Answer: A Explanation: Explanation: A provider is responsible for understanding API interactions and exposing resources. Providers generally are an IaaS (e.g. Alibaba Cloud, AWS, GCP, Microsoft Azure, OpenStack), PaaS (e.g. Heroku), or SaaS services (e.g. Terraform Cloud, DNSimple, Cloudflare).https://www.terraform.io/docs/providers/index.htmm
HashiCorp TA-002-P Sample Question 19
What is the purpose of using the local-exec provisioner? (Select Two)
Options:
Answer: A, C Explanation: Explanation: The local-exec provisioner invokes a local executable after a resource is created. This invokes a process on the machine running Terraform, not on the resource.Note that even though the resource will be fully created when the provisioner is run, there is no guarantee that it will be in an operable state - for example system services such as sshd may not be started yet on compute resources.Example usageresource "aws_instance" "web" {# ...provisioner "local-exec" {command = "echo ${aws_instance.web.private_ip} >> private_ips.txt"}}Note: Provisioners should only be used as a last resort. For most common situations there are better alternatives.https://www.terraform.io/docs/provisioners/local-exec.htmm
HashiCorp TA-002-P Sample Question 20

HashiCorp TA-002-P Sample Question 41
Multiple providers can be declared within a single Terraform configuration file.
Options:
Answer: A Explanation: Explanation: You can optionally define multiple configurations for the same provider, and select which one to use on a per-resource or per-module basis. The primary reason for this is to support multiple regions for a cloud platform; other examples include targeting multiple Docker hosts, multiple Consul hosts, etc.To include multiple configurations for a given provider, include multiple provider blocks with the same provider name, but set the alias meta-argument to an alias name to use for each additional configuration.For Example# The default provider configurationprovider "aws" {region = "us-east-1"}# Additional provider configuration for west coast regionprovider "aws" {alias = "west"region = "us-west-2"}The provider block without alias set is known as the default provider configuration. When alias is set, it creates an additional provider configuration. For providers that have no required configuration arguments, the implied empty configuration is considered to be the default provider configuration.https://www.terraform.io/docs/configuration/providers.htmm
HashiCorp TA-002-P Sample Question 42
Command terraform refresh will update state file?
Options:
Answer: B Explanation: Explanation: 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.https://www.terraform.io/docs/commands/refresh.htmm
HashiCorp TA-002-P Sample Question 43

Options:
Answer: B
HashiCorp TA-002-P Sample Question 45
Which of the below features of Terraform can be used for managing small differences between different environments which can act more like completely separate working directories.
Options:
Answer: B Explanation: Explanation: workspaces allow conveniently switching between multiple instances of a single configuration within its single backend. They are convenient in a number of situations, but cannot solve all problems.A common use for multiple workspaces is to create a parallel, distinct copy of a set of infrastructure in order to test a set of changes before modifying the main production infrastructure. For example, a developer working on a complex set of infrastructure changes might create a new temporary workspace in order to freely experiment with changes without affecting the default workspace.Non-default workspaces are often related to feature branches in version control. The default workspace might correspond to the "master" or "trunk" branch, which describes the intended state of production infrastructure. When a feature branch is created to develop a change, the developer of that feature might create a corresponding workspace and deploy into it a temporary "copy" of the main infrastructure so that changes can be tested without affecting the production infrastructure. Once the change is merged and deployed to the default workspace, the test infrastructure can be destroyed and the temporary workspace deleted.https://www.terraform.io/docs/state/workspaces.html https://www.terraform.io/docs/state/workspaces.html#when-to-use-multiple-workspacet
