Terraform KPMG Day 3

You are provisioning a set of virtual machines using Terraform, each with its own set of tags(key-value pairs) for classification and organization. Which collection type in Terraform would be most suitable for representing the set of tags for each virtual machine?

• list

• set

• object

• map

Terraform apply creates an EC2 instance (name: example)
We want Terraform to display the private_ip of the EC2 after creation automatically. How can we do this?

• output "privateip"
  {
  value = aws_instance.example.private_ip
  }

• input "privateip"
  {
  value = aws_instance.example.private_ip
  }

• data "privateip"
  {
  value = aws_instance.example.private_ip
  }

• output "privateip"
  {
  value = example.private_ip
  }

You are a DevOps engineer preparing to make updates to your company's cloud infrastructure using Terraform. Before applying the changes directly, you want to ensure everything is correct and have a way to review the planned modifications. To do this, you decide to generate a plan file.

What is the primary purpose of using the terraform plan -out update_plan command in this scenario?

• To execute the planned changes immediately.

• To save the execution plan to a file for review and future application.

• To destroy the existing infrastructure.

• To display the current state of the infrastructure.

In the context of Terraform, what does "Desired State Management" refer to?

• The current configuration of the infrastructure

• The configuration that should be applied to the infrastructure

• The historical state of the infrastructure

• The default settings of the infrastructure

What is the purpose of the "terraform.tfvars" file?

• To define variables that are specific to a particular environment

• To define variables that are automatically loaded by Terraform

• To manage state

• To define providers

Your Terraform configuration deployed a web application, including an AWS EC2 instance. Now, you require the public IP address of the instance.

• Execute terraform show and search for the public IP address in the output.

• Use the AWS Management Console to locate the public IP address.

• Check the terraform.tfstate file for the public IP address.

• Run terraform output and specify the name of the output variable containing the public IP address.

What is the main purpose of using locals in Terraform?

• To define resources that are only available within the local network and not accessible from the internet.

• To define reusable values or expressions that can be referenced within the Terraform configuration.

• To create remote connections to other Terraform configurations or infrastructure deployments.

• To manage the state of Terraform resources and track changes over time.

Which block is used to define local values in Terraform?

You are managing a Terraform configuration for deploying a network infrastructure. You need to retrieve a value from a map based on a specific key. Which function should you use?

• get()

• lookup()

• find()

• search()

Which Terraform function is used to retrieve a specific element from a list?

• lookup()

• fetch()

• search()

• element()
