NEW QUESTION # 75
You have a Terraform configuration that defines a single virtual machine with no references to it, You have run terraform apply to create the resource, and then removed the resource definition from your Terraform configuration file.
What will happen you run terraform apply in the working directory again?
- A. Terraform will remove the virtual machine from the state file, but the resource will still exist
- B. Nothing
- C. Terraform will error
- D. Terraform will destroy the virtual machine
Answer: D
Explanation:
This is what will happen if you run terraform apply in the working directory again, after removing the resource definition from your Terraform configuration file. Terraform will detect that there is a resource in the state file that is not present in the configuration file, and will assume that you want to delete it.

NEW QUESTION # 77
Which command must you first run before performing further Terraform operations in a working directory?
- A. terraform workspace
- B. terraform init
- C. terraform import
- D. terraform plan
Answer: B
Explanation:
Explanation
terraform init is the first command that should be run after writing a new Terraform configuration or cloning an existing one from version control. It initializes a working directory containing Terraform configuration files and downloads any required providers and modules. The other commands are used for different purposes, such as importing existing resources, switching between workspaces, generating execution plans, etc.
NEW QUESTION # 78
When should you run terraform init?
- A. Before you start coding a new Terraform project
- B. After you run terraform plan for the time in a new terraform project and before you run terraform apply
- C. Every time you run terraform apply
- D. After you start coding a new terraform project and before you run terraform plan for the first time.
Answer: D
Explanation:
Explanation
You should run terraform init after you start coding a new Terraform project and before you run terraform plan for the first time. This command will initialize the working directory by downloading the required providers and modules, creating the initial state file, and performing other necessary tasks. References = :

NEW QUESTION # 79
Your risk management organization requires that new AWS S3 buckets must be private and encrypted at rest. How can Terraform Cloud automatically and proactively enforce this security control?
- A. Auditing cloud storage buckets with a vulnerability scanning tool
- B. With an S3 module with proper settings for buckets
- C. By adding variables to each Terraform Cloud workspace to ensure these settings are always enabled
- D. With a Sentinel policy, which runs before every apply
Answer: D
Explanation:
The best way to automatically and proactively enforce the security control that new AWS S3 buckets must be private and encrypted at rest is with a Sentinel policy, which runs before every apply. Sentinel is a policy as code framework that allows you to define and enforce logic-based policies for your infrastructure. Terraform Cloud supports Sentinel policies for all paid tiers, and can run them before any terraform plan or terraform apply operation. You can write a Sentinel policy that checks the configuration of the S3 buckets and ensures that they have the proper settings for privacy and encryption, and then assign the policy to your Terraform Cloud organization or workspace. This way, Terraform Cloud will prevent any changes that violate the policy from being applied. Reference = [Sentinel Policy Framework], [Manage Policies in Terraform Cloud], [Write and Test Sentinel Policies for Terraform]
NEW QUESTION # 80
The_________determines how Terraform creates, updates, or delete resources.
- A. Terraform configuration
- B. Terraform core
- C. Terraform provisioner
- D. Terraform provider
Answer: D
Explanation:
Explanation
This is what determines how Terraform creates, updates, or deletes resources, as it is responsible for understanding API interactions with some service and exposing resources and data sources based on that API.
NEW QUESTION # 81
What does state looking accomplish?
- A. Copies the state file from memory to disk
- B. Blocks Terraform commands from modifying, the state file
- C. Prevent accidental Prevent accident deletion of the state file
- D. Encrypts any credentials stored within the state file
Answer: B
Explanation:
Explanation
This is what state locking accomplishes, by preventing other users from modifying the state file while a Terraform operation is in progress. This prevents conflicts and data loss.
NEW QUESTION # 82
You're building a CI/CD (continuous integration/continuous delivery) pipeline and need to inject sensitive variables into your Terraform run. How can you do this safely?
- A. Pass variables to Terraform with a -var flag
- B. Copy the sensitive variables into your Terraform code
- C. Store the sensitive variables as plain text in a source code repository
- D. Store the sensitive variables in a secure_varS.tf file
Answer: A
Explanation:
This is a secure way to inject sensitive variables into your Terraform run, as they will not be stored in any file or source code repository. You can also use environment variables or variable files with encryption to pass sensitive variables to Terraform.
NEW QUESTION # 83
When using multiple configuration of the same Terraform provider, what meta-argument must you include in any non-default provider configurations?
- A. Id
- B. name
- C. Depends_on
- D. Alias
Answer: D
Explanation:
Explanation
This is the meta-argument that you must include in any non-default provider configurations, as it allows you to give a friendly name to the configuration and reference it in other parts of your code. The other options are either invalid or irrelevant for this purpose.
NEW QUESTION # 84
Module variable assignments are inherited from the parent module and you do not need to explicitly set them.
- A. False
- B. True
Answer: A
Explanation:
Explanation
Module variable assignments are not inherited from the parent module and you need to explicitly set them using the source argument. This allows you to customize the behavior of each module instance.
NEW QUESTION # 85
If you manually destroy infrastructure, what is the best practice reflecting this change in Terraform?
- A. Manually update the state fire
- B. It will happen automatically
- C. Run terraform import
- D. Run terraform refresh
Answer: B
Explanation:
If you manually destroy infrastructure, Terraform will automatically detect the change and update the state file during the next plan or apply. Terraform compares the current state of the infrastructure with the desired state in the configuration and generates a plan to reconcile the differences. If a resource is missing from the infrastructure but still exists in the state file, Terraform will attempt to recreate it. If a resource is present in the infrastructure but not in the state file, Terraform will ignore it unless you use the terraform import command to bring it under Terraform's management. Reference = [Terraform State]
NEW QUESTION # 86
Which of the following does terraform apply change after you approve the execution plan? (Choose two.)
- A. The .terraform directory
- B. Terraform code
- C. The execution plan
- D. Cloud infrastructure Most Voted
- E. State file
Answer: D,E
Explanation:
The terraform apply command changes both the cloud infrastructure and the state file after you approve the execution plan. The command creates, updates, or destroys the infrastructure resources to match the configuration. It also updates the state file to reflect the new state of the infrastructure. The .terraform directory, the execution plan, and the Terraform code are not changed by the terraform apply command. Reference = Command: apply and Purpose of Terraform State
NEW QUESTION # 87
You add a new resource to an existing Terraform configuration, but do not update the version constraint in the configuration. The existing and new resources use the same provider. The working contains a .terraform.lock, hc1 file.
How will Terraform choose which version of the provider to use?
- A. Terraform will use the latest version of the provider available at the time you provision your new resource
- B. Terraform will check your state file to determine the provider version to use
- C. Terraform will use the latest version of the provider for the new resource and the version recorded in the lock file to manage existing resources
- D. Terraform will use the version recorded in your lock file
Answer: D
Explanation:
Explanation
This is how Terraform chooses which version of the provider to use, when you add a new resource to an existing Terraform configuration, but do not update the version constraint in the configuration. The lock file records the exact version of each provider that was installed in your working directory, and ensures that Terraform will always use the same provider versions until you run terraform init -upgrade to update them.
NEW QUESTION # 88
How would you output returned values from a child module in the Terraform CLI output?
- A. Declare the output in the child module
- B. None of the above
- C. Declare the output in both the root and child module
- D. Declare the output in the root configuration
Answer: C
Explanation:
Explanation
To output returned values from a child module in the Terraform CLI output, you need to declare the output in both the child module and the root module. The child module output will return the value to the root module, and the root module output will display the value in the CLI. References = [Terraform Outputs]
NEW QUESTION # 89
Terraform can only manage resource dependencies if you set them explicitly with the depends_on argument.
- A. False
- B. True
Answer: A
Explanation:
Terraform can manage resource dependencies implicitly or explicitly. Implicit dependencies are created when a resource references another resource or data source in its arguments. Terraform can infer the dependency from the reference and create or destroy the resources in the correct order. Explicit dependencies are created when you use the depends_on argument to specify that a resource depends on another resource or module. This is useful when Terraform cannot infer the dependency from the configuration or when you need to create a dependency for some reason outside of Terraform's scope. Reference = : Create resource dependencies : Terraform Resource Dependencies Explained
NEW QUESTION # 90
Terraform providers are always installed from the Internet.
- A. False
- B. True
Answer: A
Explanation:
Terraform providers are not always installed from the Internet. There are other ways to install provider plugins, such as from a local mirror or cache, from a local filesystem directory, or from a network filesystem. These methods can be useful for offline or air-gapped environments, or for customizing the installation process. You can configure the provider installation methods using the provider_installation block in the CLI configuration file.
NEW QUESTION # 91
You have never used Terraform before and would like to test it out using a shared team account for a cloud provider. The shared team account already contains 15 virtual machines (VM). You develop a Terraform configuration containing one VM. perform terraform apply, and see that your VM was created successfully. What should you do to delete the newly-created VM with Terraform?
- A. Delete the VM using the cloud provider console and terraform apply to apply the changes to the Terraform state file.
- B. The Terraform state file only contains the one new VM. Execute terraform destroy.
- C. The Terraform state file contains all 16 VMs in the team account. Execute terraform destroy and select the newly-created VM.
- D. Delete the Terraform state file and execute terraform apply.
Answer: B
Explanation:
This is the best way to delete the newly-created VM with Terraform, as it will only affect the resource that was created by your configuration and state file. The other options are either incorrect or inefficient.
NEW QUESTION # 92
How does the Terraform cloud integration differ from other state backends such as S3, Consul,etc?
- A. It doesn't show the output of a terraform apply locally
- B. All of the above
- C. It can execute Terraform runs on dedicated infrastructure in Terraform Cloud
- D. It is only arable lo paying customers
Answer: C
Explanation:
Explanation
This is how the Terraform Cloud integration differs from other state backends such as S3, Consul, etc., as it allows you to perform remote operations on Terraform Cloud's servers instead of your local machine. The other options are either incorrect or irrelevant.
