Which of the following statements represents the most accurate statement about the Terraform language?

• • Terraform is a mutable, imperative, Infrastructure as Code provisioning language based on Hashicorp Configuration Language, or optionally YAML.

• • Terraform is an immutable, declarative, Infrastructure as Code provisioning language based on Hashicorp Configuration Language, or optionally JSON.

• • Terraform is a mutable, declarative, Infrastructure as Code configuration management language based on Hashicorp Configuration Language, or optionally JSON.

• • Terraform is an immutable, imperative, Infrastructure as Code configuration management language based on Hashicorp Configuration Language, or optionally JSON.

Why might a user opt to include the following snippet in their configuration file?

1. terraform {

2. required_version = ">= 1.9.2"

3. }

• The user wants to specify the minimum version of Terraform that is required to run the configuration

• • The user wants to ensure that the application being deployed is a minimum version of 1.9.2

• • versions before Terraform 1.9.2 were not approved by HashiCorp to be used in production

• • this ensures that all Terraform providers are above a certain version to match the application being deployed

Which of the following are tasks that terraform apply can perform? (select three)

• • import existing infrastructure

• • provision new infrastructure

• • update existing infrastructure with new configurations

• • destroy infrastructure previously deployed with Terraform

Your organization has multiple engineers that have permission to manage Terraform as well as administrative access to the public cloud where these resources are provisioned. If an engineer makes a change outside of Terraform, what command can you run to detect drift and update the state file?

• • terraform get

• • terraform init

• • terraform state list

• • terraform apply -refresh-only

Infrastructure as Code (IaC) provides many benefits to help organizations deploy application infrastructure much faster than manually clicking in the console. Which is NOT an additional benefit to IaC?

• • allows infrastructure to be versioned

• • eliminates API communication to the target platform

• • code can easily be shared and reused

• • creates self-documenting infrastructure

Rather than having to scan and inspect every resource on every run, Terraform relies on what feature to help manage resources?

• • local variables

• • state

• • providers

• • environment variables

What feature does Terraform use to map configuration to resources in the real world?

• • state

• • parallelism

• • resource blocks

• • local variables

Given the code snippet below, how would you identify the arn to be used in the output block that was retrieved by the data block?

1. ```
   data "aws_s3_bucket" "data-bucket" {

2. bucket = "my-data-lookup-bucket-btk"

3. }

4. ...

5.  

6. output "s3_bucket_arn" {

7. value = ????

8. }

• ```

• • aws_s3_bucket.data-bucket

• • data.aws_s3_bucket.data-bucket.arn

• • data.aws_s3_bucket.arn

• • data.aws_s3_bucket.data-bucket

True or False? When referencing a module, you must specify the version of the module in the calling module block.

• True

• False

You've included two different modules from the official Terraform registry in a new configuration file. When you run a terraform init, where does Terraform OSS download and store the modules locally?

• • in the same root directory where the Terraform configuration files are stored

• • Terraform stores them in memory on the machine running Terraform

• • in the .terraform/modules folder in the working directory

• • in the /tmp directory of the machine executing Terraform
