QUESTION 31
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.

 True

 False

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.
String
Strings 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 = string
default = “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.template
List
Another 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 = list
default = [“root”, “user1”, “user2”]
}
Lists can be used in the resource plans similarly to strings, but you’ll also need to denote the index of the value you are looking for.
username = var.users[0]
Map
Maps 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 = map
default = {
“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 = map
default = {
“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”])
Boolean
The 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_password
By 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”

QUESTION 32
What information does the public Terraform Module Registry automatically expose about published modules?

 Required input variables

 Optional inputs variables and default values

 Outputs

 All of the above

 None of the above

QUESTION 33
terraform refresh will update the state file?

 True

 False

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.

QUESTION 34
True or False? Each Terraform workspace uses its own state file to manage the infrastructure associated with that particular workspace.

 False

 True

Explanation
The persistent data stored in the backend belongs to a workspace. Initially, the backend has only one workspace, called “default”, and thus there is only one Terraform state associated with that configuration.

QUESTION 35
True or False? By default, Terraform destroy will prompt for confirmation before proceeding.

 False

 True

QUESTION 36
True or False. The terraform refresh command is used to reconcile the state Terraform knows about (via its state file) with the real-world infrastructure. If drift is detected between the real-world infrastructure and the last known-state, it will modify the infrastructure to correct the drift.

 False

 True
Explanation

QUESTION 37
Terraform will sync all resources in state by default for every plan and apply, hence for larger infrastructures
this can slow down terraform plan and terraform apply commands?

 False

 True

Explanation
For small infrastructures, Terraform can query your providers and sync the latest attributes from all your
resources. This is the default behavior of Terraform: for every plan and apply, Terraform will sync all
resources in your state.
For larger infrastructures, querying every resource is too slow. Many cloud providers do not provide APIs to
query multiple resources at once, and the round trip time for each resource is hundreds of milliseconds. On top
of this, cloud providers almost always have API rate limiting so Terraform can only request a certain number
of resources in a period of time. Larger users of Terraform make heavy use of the -refresh=false flag as well as
the -target flag in order to work around this. In these scenarios, the cached state is treated as the record of
truth.

QUESTION 38
You cannot publish your own modules on the Terraform Registry.

 False

 True

Anyone can publish and share modules on the Terraform Registry.
https://www.terraform.io/docs/registry/modules/publish.html

QUESTION 39
By default, provisioners that fail will also cause the Terraform apply itself to error. How can you change this
default behavior within a provisioner?

 provisioner “local-exec” { on_failure = “next” }

 provisioner “local-exec” { when = “failure” terraform apply }

 provisioner “local-exec” { on_failure = “continue” }

 provisioner “local-exec” { on_failure = continue }

Explanation
https://www.terraform.io/docs/provisioners/index.html

QUESTION 40
You want to know from which paths Terraform is loading providers referenced in your Terraform configuration (* files). You need to enable additional logging messages to find this out. Which of the following would achieve this?

 Set verbose for each provider in your Terraform configuration

 Set the environment variable TF_LOG_TRACE

 Set the environment variable TF_LOG_PATH

 Set the environment variable TF_log_TRACE

This will enable additional logging messages to find out from which paths Terraform is loading providers referenced in your Terraform configuration files, as it will set the log level to TRACE, which is the most verbose and detailed level.

QUESTION 41
What is the Terraform style convention for indenting a nesting level compared to the one above it?

 With a tab

 With two spaces

 With four spaces

 With three spaces

This is the Terraform style convention for indenting a nesting level compared to the one above it. The other options are not consistent with the Terraform style guide.

QUESTION 42
Terraform and Terraform providers must use the same major version number in a single configuration.

 True

 False

Explanation
https://www.terraform.io/language/expressions/version-constraints#terraform-core-and-provider-versions

QUESTION 43
Which of the below are paid features of Terraform Cloud?

 Full API Coverage

 Secure variable Storage

 Roles/ Team management

 Cost Estimation

 Private Module Registry

 Sentinel policies

https://www.hashicorp.com/products/terraform/pricing/

QUESTION 44
Refer to the following terraform variable definition
variable “track_tag” { type = list default = [“data_ec2″,”integration_ec2″,”digital_ec2”]} track_tag = { Name =
element(var.track_tag,count.index)}
If count.index is set to 2, which of the following values will be assigned to the name attribute of track_tag
variable?

 integration_ec2

 digital_ec2

 track_tag

 data_ec2

QUESTION 45
Which command add existing resources into Terraform state?

 Terraform init

 Terraform plan

 Terraform refresh

 Terraform import

 All of these

This is the command that can add existing resources into Terraform state, by matching them with the corresponding configuration blocks in your files.
