Scenario: You have a Terraform configuration file with no defined resources. However, there is a related state file for resources that were created on AWS. What happens when you run a terraform apply? Terraform will produce an error since there are no resources defined Terraform will not perform any operations. Terraform will scan the AWS infrastructure and create a new configuration file based on the state file Terraform will destroy all of the resources.
Shahin a Terraform config that includes the following code, how would you reference the last instance that will be created? 1 resource "aws_instance" "database" { 2 # ... 3 for_each = { 4 "vault": "value1", 5 "terraform": "value2", 6 "consul": "value3", 7 "nomad": "value4", 8 } 9 } aws_instance.database["nomad"] aws_instance.database[3] aws_instance.nomad aws_instance.database[4].
True or False? Any sensitive values referenced in the Terraform code, even as variables, will end up in plain text in the state file. True False.
Arvin is new to Terraform and has a single configuration file that is ready to be deployed. Which of the following can be true about this configuration file? (select three) the state file can be stored in Azure but provision applications in AWS Arvin's configuration file can deploy applications in both AWS and GCP the state can be disabled when deploying to multiple clouds to prevent sensitive data from being shared across cloud platforms the configuration file can deploy both QA and Staging infrastructure for applications.
True or False? A terraform plan is a required step before running a terraform apply? True False.
Variables and their default values are typically declared in a main.tf or terraform.tf file. What type of file can be used to set explicit values for the current working directory that will override the default variable values? .tfvars file .txt file .tfstate file .sh file.
Zahra has executed a terraform apply using a complex Terraform configuration file. However, a few resources failed to deploy due to incorrect variables. After the error is discovered, what happens to the resources that were successfully provisioned? Terraform deletes the resources on the next run resources successfully deployed are marked as tainted the resources that were successfully provisioned will remain as deployed Terraform rolls back the configuration due to the error, therefore the resources are automatically destroyed.
Which of the following best describes a "data source"? enables Terraform to fetch data for use elsewhere in the Terraform configuration a file that contains the current working version of Terraform provides required data for declared variables used within the Terraform configuration maintains a list of strings to store the values of declared outputs in Terraform.
Bijan is a DevOps Engineer for a large company and is currently managing the infrastructure for many different applications using Terraform. Recently, Bijan received a request to remove a specific VMware virtual machine from Terraform as it is no longer needed by the application team. Bijan opens his terminal and issues the command: $ terraform state rm vsphere_virtual_machine.app1 Removed vsphere_virtual_machine.app1 Successfully removed 1 resource instance(s). The next time that Bijan runs a terraform apply, the resource is not marked to be deleted. In fact, Terraform is stating that it is creating another identical resource. ..... An execution plan has been generated and is shown below. Resource actions are indicated with the following symbols: + create Terraform will perform the following actions: # vsphere_virtual_machine.app1 will be created What would explain this behavior? the state file was not saved before the terraform apply was executed, therefore Terraform sees that the resource is still in the state file after running the terraform rm command, Bijan needs to run a Terraform plan first to tell Terraform of the updated configuration. A plan will instruct Terraform that the resource should be deleted upon the next terraform apply Bijan removed the resource from the state file, and not the configuration file. Therefore, Terraform is no longer aware of the virtual machine and assumes Bijan wants to create a new one since the virtual machine is still in the Terraform configuration file the resource was manually deleted within the VMware infrastructure and needs to be recreated.

Amira is calling a child module to deploy infrastructure for her organization. Just as a good architect does (and suggested by HashiCorp), she specifies the module version she wants to use even though there are newer versions available. During a terrafom init, Terraform downloads v0.0.5 just as expected. What would happen if Amira removed the version parameter in the module block and ran a terraform init again? module "consul" { source = "hashicorp/consul/aws" version = "0.0.5" servers = 3 } Terraform would skip the module Terraform would return an error, as the version parameter is required Terraform would download the latest version of the module Terraform would use the existing module already downloaded.

Ario 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, Ario 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 Ario 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? Terraform can only destroy a maximum of 2 resources per terraform destroy execution the vSphere provider credentials are invalid, and therefore Terraform cannot reach the third virtual machine the virtual machine was marked with vSphere tags to prevent it from being destroyed the remaining virtual machine was not created by Terraform, therefore Terraform is not aware of the virtual machine and cannot destroy it.
