Terraform init can indeed be run only a few times, because, every time terraform init will initialize the
project , and download all plugins from the internet repository , regardless of whether they were present
or not , and this increases the waiting time
A. True
B. False
Answer: B
Explanation:
Re-running init with modules already installed will install the sources for any modules that were added
to configuration since the last init, but will not change any already-installed modules. Use -upgrade to
override this behavior, updating all modules to the latest available source code.

terraform refresh command will not modify infrastructure, but does modify the state file.
A. True
B. False
Answer: A
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.

Question: 7
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.
A. True
B. False
Answer: B
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"]
,Questions & Answers PDF Page 5
}
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: 8
, Questions & Answers PDF Page 6
Environment variables can be used to set variables. The environment variables must be in the format
"____"_<variablename>. Select the correct prefix string from the following list.
A. TF_CLI_ARGS
B. TF_VAR
C. TF_VAR_
D. TF_VAR_ENV
Answer: C
Explanation:
Environment variables can be used to set variables. The environment variables must be in the format
TF_VAR_name and this will be checked last for a value. For example:
export TF_VAR_region=us-west-1
export TF_VAR_ami=ami-049d8641
export TF_VAR_alist='[1,2,3]'
export TF_VAR_amap='{ foo = "bar", baz = "qux" }'

Question: 9
The terraform init command is always safe to run multiple times, to bring the working directory up to
date with changes in the configuration. Though subsequent runs may give errors, this command will
never delete your existing configuration or state.
ABC Enterprise has recently tied up with multiple small organizations for exchanging database
information. Due to this, the firewall rules are increasing and are more than 100 rules. This is leading
firewall configuration file that is difficult to manage. What is the way this type of configuration can be
managed easily?
A. Terraform Backends
B. Terraform Functions
C. Dynamic Blocks
D. Terraform Expression
