Question 1

You modified your Terraform configuration and run Terraform plan to review the changes. Simultaneously, your teammate manually modified the infrastructure component you are working on. Since you already ran terraform plan locally, the execution plan for terraform apply will be the same.

Options :

A : True

B : False

Answer: B

Question 2

Sara has her entire application automated using Terraform, but she needs to start automating more infrastructure components, such as creating a new subnet, DNS record, and load balancer. Sara wants to create these new resources using modules so she easily reuse the code. However, Sara is having problems getting the subnet_id from the subnet module to pass to the load balancer module.

modules/subnet.tf:

resource "aws_subnet" "bryan" {

vpc_id = aws_vpc.krausen.id

cidr_block = "10.0.1.0/24"

tags = {

Name = "Krausen Subnet"

}

What could fix this problem?

Options :

A : add an output block to the subnet module and retrieve the value using module.subnet.subnet_id for the load balancer module

B : move the subnet and load balancer resource into the main configuration file so they can easily be referenced

C : publish the module to a Terraform registry first

D : references to resources that are created within a module cannot be used within other modules

Answer: A

Question 3

When using Terraform, which command allows you to modify a resource in your infrastructure?

Options :

A : terraform plan

B : terraform apply

C : terraform destroy

D : terraform validate

Answer: B

Question 4

Philip works at a payment processing company and manages the organization's VMware environment. He recently provisioned a new cluster for a production environment. To ensure everything is working as expected, Philip has been using Terraform and the VMware vSphere client to create and destroy new virtual machines. Currently, there are three virtual machines running on the new cluster, so Philip runs terraform destroy to remove the remaining virtual machines from the cluster. However, Terraform only removes two of the virtual machines, leaving one virtual machine still running.

Why would Terraform only remove two of the three virtual machines?

Options :

A : the virtual machine was marked with vSphere tags to prevent it from being destroyed

B : the remaining virtual machine was not created by Terraform, therefore Terraform is not aware of the virtual machine and cannot destroy it

C : Terraform can only destroy a maximum of 2 resources per terraform destroy execution

D : the vSphere provider credentials are invalid, and therefore Terraform cannot reach the third virtual machine

Answer: B

Question 5

You want Terraform to redeploy a specific resource that it is managing. What command should you use to mark the resource for replacement?

Options :

A : terraform fmt

B : terraform destroy

C : terraform apply -replace

D : terraform plan -destroy
