Infrastructure as code (IaC) is a standard practice of maintaining infrastructure configuration as code. Terraform is a cross-platform tool that introduces the HashiCorp Configuration Language (HCL) for the provisioning of infrastructures on different cloud platforms like Azure, AWS, and Google Cloud.

First you’ll learn about the basics of IaC and the tools used for it. Next, you’ll learn about Terraform, how to deploy resources using it, and the Terraform state file. Then you’ll cover the basics of HCL, followed by how to work with outputs, expressions, and loops. You’ll also cover local and remote provisioners, and learn how to employ HCL to provision and manage resources using different concepts like modules, variables, provisioners, and the Terraform state file. Finally, you’ll learn how to use the Terraform Cloud.

By the end of this course, you’ll be able to provision, delete, and update resources on a cloud platform using Terraform. Knowing how to use Terraform effectively will set you up for success.

Which option does *not* define variables?

Which option does not define variables?

 ```
validation {
   condition     = length(var.instance_type) > 3 && substr(var.instance_type, 0, 2) == "t2."
   error_message = "You can only specify a t2 instance"
 }
```

 ```
validation {
   condition     = length(var.instance_type) > 3 && (var.instance_type, 0, 1) == "t2."
   error_message = "You can only specify a t2 instance"
 }
```

 ```
validation {
   condition     = length(var.instance_type) > 3 && (var.instance_type, 0, 2) == "t2."
   error_message = "You can only specify a t2 instance"
 }
```

 ```
validation {
   condition     = length(var.instance_type) > 3 && substr(var.instance_type, 0, 1) == "t2."
   error_message = "You can only specify a t2 instance"
 }
```

Which option correctly enforces validation for `instance_type` such that it should be longer than three characters and should start with `t2.`? 

Which option correctly enforces validation for <code>instance_type</code> such that it should be longer than three characters and should start with <code>t2.</code>?

**(True or False)** An output value can't be concealed in Terraform.

(True or False) An output value can’t be concealed in Terraform.

We've been tasked with the responsibility of using Terraform to provision four instances simultaneously. Which type of loop can we use to achieve this?

We’ve been tasked with the responsibility of using Terraform to provision four instances simultaneously. Which type of loop can we use to achieve this?

What will be the value of `count` in the code snippet below?

```plain
locals {
  min_value = 2
  max_value = 10
}

variable "count" {
  type = number
  default = local.min_value + (local.max_value - local.min_value) / 2
}
```

What will be the value of <code>count</code> in the code snippet below?
<pre><code class="language-plain">locals {
 min_value = 2
 max_value = 10
}

variable &quot;count&quot; {
 type = number
 default = local.min_value + (local.max_value - local.min_value) / 2
}
</code></pre>
