NEW QUESTION # 77
You add a new provider to your configuration and immediately run terraform apply in the CD using the local backend. Why does the apply fail?
- A. The Terraform CD needs you to log into Terraform Cloud first
- B. Terraform needs you to format your code according to best practices first
- C. Terraform requires you to manually run terraform plan first
- D. Terraform needs to install the necessary plugins first
Answer: D
Explanation:
The reason why the apply fails after adding a new provider to the configuration and immediately running terraform apply in the CD using the local backend is because Terraform needs to install the necessary plugins first. Terraform providers are plugins that Terraform uses to interact with various cloud services and other APIs. Each provider has a source address that determines where to download it from. When Terraform encounters a new provider in the configuration, it needs to run terraform init first to install the provider plugins in a local directory. Without the plugins, Terraform cannot communicate with the provider and perform the desired actions. References = [Provider Requirements], [Provider Installation]
NEW QUESTION # 78
Which of the following are advantages of using infrastructure as code (laC) instead of provisioning with a graphical user interface (GUI)? Choose two correct answers.
- A. Lets you version, reuse, and share infrastructure configuration
- B. Secures your credentials
- C. Reduces risk of operator error
- D. Provisions the same resources at a lower cost
- E. Prevents manual modifications to your resources
Answer: A,C
Explanation:
Infrastructure as code (IaC) is a way of managing and provisioning cloud infrastructure using programming techniques instead of manual processes1. IaC has many advantages over using a graphical user interface (GUI) for provisioning infrastructure, such as:
*Versioning: IaC allows you to store your infrastructure configuration in a version control system, such as Git, and track changes over time. This enables you to roll back to previous versions, compare differences, and collaborate with other developers2.
*Reusability: IaC allows you to create reusable modules and templates that can be applied to different environments, such as development, testing, and production. This reduces duplication, improves consistency, and speeds up deployment3.
*Sharing: IaC allows you to share your infrastructure configuration with other developers, teams, or organizations, and leverage existing code from open source repositories or registries. This fosters best practices, innovation, and standardization4.
*Risk reduction: IaC reduces the risk of human error, configuration drift, and security breaches that can occur when provisioning infrastructure manually or using a GUI. IaC also enables you to perform automated testing, validation, and compliance checks on your infrastructure before deploying it5.

NEW QUESTION # 80
A provider configuration block is required in every Terraform configuration.
Example:
- A. False
- B. True
Answer: A
Explanation:
A provider configuration block is not required in every Terraform configuration. A provider configuration block can be omitted if its contents would otherwise be empty. Terraform assumes an empty default configuration for any provider that is not explicitly configured. However, some providers may require some configuration arguments (such as endpoint URLs or cloud regions) before they can be used. A provider's documentation should list which configuration arguments it expects. For providers distributed on the Terraform Registry, versioned documentation is available on each provider's page, via the "Documentation" link in the provider's header1. References = [Provider Configuration]1
NEW QUESTION # 81

NEW QUESTION # 82
You are using a networking module in your Terraform configuration with the name label my-network. In your main configuration you have the following code:
When you run terraform validate, you get the following error:
What must you do to successfully retrieve this value from your networking module?
- A. Change the reference value to my-network,outputs,vmet_id
- B. Define the attribute vmet_id as a variable in the networking modeule
- C. Change the reference value module.my,network,outputs,vnet_id
- D. Define the attribute vnet_id as an output in the networking module
Answer: D
Explanation:
Explanation
This is what you must do to successfully retrieve this value from your networking module, as it will expose the attribute as an output value that can be referenced by other modules or resources. The error message indicates that the networking module does not have an output value named vnet_id, which causes the reference to fail.

- A. The .terraform directory
- B. Cloud infrastructure Most Voted
- C. The execution plan
- D. Terraform code
- E. State file
Answer: B,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. References = Command: apply and Purpose of Terraform State

- A. Terraform automatically builds a resource graph based on resources provisioners, special meta-parameters, and the stale file (if present}
- B. Terraform requires resources in a configuration to be listed m the order they will be created to determine dependencies
- C. Terraform requires all dependencies between resources to be specified using the depends_on parameter
- D. Terraform requires resource dependencies to be defined as modules and sourced in order
Answer: A
Explanation:
Explanation
This is how Terraform determines dependencies between resources, by using the references between them in the configuration files and other factors that affect the order of operations.
NEW QUESTION # 87
Which Terraform collection type should you use to store key/value pairs?
- A. list
- B. Map
- C. Tuple
- D. Set
Answer: B
Explanation:
The Terraform collection type that should be used to store key/value pairs is map. A map is a collection of values that are accessed by arbitrary labels, called keys. The keys and values can be of any type, but the keys must be unique within a map. For example, var = { key1 = "value1", key2 = "value2" } is a map with two key/value pairs. Maps are useful for grouping related values together, such as configuration options or metadata. References = [Collection Types], [Map Type Constraints]
NEW QUESTION # 88

NEW QUESTION # 93
In a Terraform Cloud workspace linked to a version control repository, speculative plan runs start automatically when you merge or commit changes to version control.
- A. False
- B. True
Answer: A
Explanation:
In Terraform Cloud, speculative plan runs are not automatically started when changes are merged or committed to the version control repository linked to a workspace. Instead, speculative plans are typically triggered as part of proposed changes in merge requests or pull requests to give an indication of what would happen if the changes were applied, without making any real changes to the infrastructure. Actual plan and apply operations in Terraform Cloud workspaces are usually triggered by specific events or configurations defined within the Terraform Cloud workspace settings.References= This behavior is part of how Terraform Cloud integrates with version control systems and is documented in Terraform Cloud's usage guidelines and best practices, especially in the context of VCS-driven workflows.
NEW QUESTION # 94
Terraform configuration (including any module references) can contain only one Terraform provider type.
- A. False
- B. True
Answer: A
Explanation:
Terraform configuration (including any module references) can contain more than one Terraform provider type. Terraform providers are plugins that Terraform uses to interact with various cloud services and other APIs. A Terraform configuration can use multiple providers to manage resources across different platforms and services. For example, a configuration can use the AWS provider to create a virtual machine, the Cloudflare provider to manage DNS records, and the GitHub provider to create a repository. Terraform supports hundreds of providers for different use cases and scenarios. Reference = [Providers], [Provider Requirements], [Provider Configuration]
NEW QUESTION # 95
A terraform apply can not _________ infrastructure.
- A. provision
- B. change
- C. import
- D. destroy
Answer: C
Explanation:
The terraform import command is used to import existing infrastructure into Terraform's state. This allows Terraform to manage and destroy the imported infrastructure as part of the configuration. The terraform import command does not modify the configuration, so the imported resources must be manually added to the configuration after the import. References = [Importing Infrastructure]
NEW QUESTION # 96
How does the Terraform cloud integration differ from other state backends such as S3, Consul,etc?
- A. It can execute Terraform runs on dedicated infrastructure in Terraform Cloud
- B. All of the above
- C. It doesn't show the output of a terraform apply locally
- D. It is only arable lo paying customers
Answer: A
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.
NEW QUESTION # 97
The public Terraform Module Registry is free to use.
- A. True
- B. False
Answer: A
Explanation:
The public Terraform Module Registry is free to use, as it is a public service that hosts thousands of self-contained packages called modules that are used to provision infrastructure. You can browse, use, and publish modules to the registry without any cost.
NEW QUESTION # 98
What does Terraform use the .terraform.lock.hc1 file for?
- A. Storing references to workspaces which are locked
- B. Preventing Terraform runs from occurring
- C. Tracking specific provider dependencies
- D. There is no such file
Answer: C
Explanation:

NEW QUESTION # 99
Which two steps are required to provision new infrastructure in the Terraform workflow? Choose two correct answers.
- A. Plan
- B. Init
- C. apply
- D. Alidate
- E. Import
Answer: B,C
Explanation:
The two steps that are required to provision new infrastructure in the Terraform workflow are init and apply.
The terraform init command initializes a working directory containingTerraform configuration files. It downloads and installs the provider plugins that are needed for the configuration, and prepares the backend for storing the state. The terraform apply command applies the changes required to reach the desired state of the configuration, as described by the resource definitions in the configuration files. It shows a plan of the proposed changes and asks for confirmation before making any changes to the infrastructure. References =

Answer: B,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 # 101
How could you reference an attribute from the vsphere_datacenter data source for use with the datacenter_id argument within the vsphere_folder resource in the following configuration?
- A. Data,dc,id
- B. Data.vsphere_datacenter.DC.id
- C. Data.vsphere_datacenter,dc
- D. Vsphere_datacenter.dc.id
Answer: B
Explanation:
Explanation
The correct way to reference an attribute from the vsphere_datacenter data source for use with the datacenter_id argument within the vsphere_folder resource in the following configuration is data.vsphere_datacenter.dc.id. This follows the syntax for accessing data source attributes, which is data.TYPE.NAME.ATTRIBUTE. In this case, the data source type is vsphere_datacenter, the data source name is dc, and the attribute we want to access is id. The other options are incorrect because they either use the wrong syntax, the wrong punctuation, or the wrong case. References = [Data Source: vsphere_datacenter],
[Data Source: vsphere_folder], [Expressions: Data Source References]
