Question 1

Which of the following is not true of Terraform providers?

AAn individual person can write a Terraform Provider

BA community of users can maintain a provider

CHashiCorp maintains some providers

DCloud providers and infrastructure vendors can write, maintain, or collaborate on Terraform

Eproviders

FNone of the above

Answer : F

All of the statements are true of Terraform providers. Terraform providers are plugins that enable Terraform to interact with various APIs and services1. Anyone can write a Terraform provider, either as an individual or as part of a community2. HashiCorp maintains some providers, such as the AWS, Azure, and Google Cloud providers3. Cloud providers and infrastructure vendors can also write, maintain, or collaborate on Terraform providers, such as the VMware, Oracle, and Alibaba Cloud providers. Reference =

Question 2

You used Terraform to create an ephemeral development environment in the cloud and are now ready to destroy all the infrastructure described by your Terraform configuration. To be safe, you would like to first see all the infrastructure that Terraform will delete.

Which command should you use to show all the resources that will be deleted? (Pick the 2 correct responses)

ARunterraform destroy. This will output all the resources that will be deleted before prompting for approval.

BRunterraform show -destroy.

CRunterraform state rm *.

Answer : A, B

Runningterraform destroywill show all resources that will be deleted before prompting for approval. You can also runterraform plan -destroyto simulate the destruction without actually applying it, which is useful for reviewing the planned changes.

Terraform Destroy

Question 3

You can develop a custom provider to manage its resources using Terraform.

ATrue

BFalse

Answer : A

You can develop a custom provider to manage its resources using Terraform, as Terraform is an extensible tool that allows you to write your own plugins in Go language. You can also publish your custom provider to the Terraform Registry or use it privately.

Question 4

When using Terraform to deploy resources into Azure, which scenarios are true regarding state files? (Choose two.)

AWhen you change a Terraform-managed resource via the Azure Cloud Console, Terraform updates the state file to reflect the change during the next plan or apply

BChanging resources via the Azure Cloud Console records the change in the current state file

CWhen you change a resource via the Azure Cloud Console, Terraform records the changes in a new state file

DChanging resources via the Azure Cloud Console does not update current state file

Answer : A, D

Terraform state is a representation of the infrastructure that Terraform manages. Terraform uses state to track the current status of the resources it creates and to plan future changes. However, Terraform state is not aware of any changes made to the resources outside of Terraform, such as through the Azure Cloud Console, the Azure CLI, or the Azure API. Therefore, changing resources via the Azure Cloud Console does not update the current state file, and it may cause inconsistencies or conflicts with Terraform's desired configuration. To avoid this, it is recommended to manage resources exclusively through Terraform or to use theterraform importcommand to bring existing resources under Terraform's control.

When you change a Terraform-managed resource via the Azure Cloud Console, Terraform does not immediately update the state file to reflect the change. However, the next time you runterraform planorterraform apply, Terraform will compare the state file with the actual state of the resources in Azure and detect any drifts or differences. Terraform will then update the state file to match the current state of the resources and show you the proposed changes in the execution plan. Depending on the configuration and the change, Terraform may try to undo the change, modify the resource further, or recreate the resource entirely. To avoid unexpected or destructive changes, it is recommended to review the execution plan carefully before applying it or to use theterraform refreshcommand to update the state file without applying any changes.

Question 5

Why does this backend configuration not follow best practices?

AAn alias meta-argument should be included in backend blocks whenever possible

BYou should use the local enhanced storage backend whenever possible

CYou should not store credentials in Terraform configuration

DThe backend configuration should contain multiple credentials so that more than one user can execute terraform plan and terraform apply

Answer : C

This is a bad practice, as it exposes your credentials to anyone who can access your configuration files or state files. You should use environment variables, credential files, or other mechanisms to provide credentials to Terraform.

Question 6

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

AWith two spaces.

BWith four spaces.

CWith three spaces.

DWith a tab.

Answer : A

Terraform's Indentation Standards: Terraform's style convention usestwo spaces per nesting levelfor readability, helping to maintain uniform code across teams.

Configuration Files: Consistent indentation is crucial for Terraform's HCL syntax, as it improves readability and avoids parsing issues.

More details are available in theTerraform configuration style guide.

Question 7

terraform plan updates your state file.

ATrue

BFalse

Answer : B

The terraform plan command does not update the state file. Instead, it reads the current state and the configuration files to determine what changes would be made to bring the real-world infrastructure into the desired state defined in the configuration. The plan operation is a read-only operation and does not modify the state or the infrastructure. It is the terraform apply command that actually applies changes and updates the state file.Reference = Terraform's official guidelines and documentation clarify the purpose of the terraform plan command, highlighting its role in preparing and showing an execution plan without making any changes to the actual state or infrastructure .
