NEW QUESTION # 34
Which configuration consistency errors does terraform validate report?
- A. A mix of spaces and tabs in configuration files
- B. Declaring a resource identifier more than once
- C. Terraform module isn't the latest version
- D. Differences between local and remote state
Answer: B
Explanation:
Explanation
Terraform validate reports configuration consistency errors, such as declaring a resource identifier more than once. This means that the same resource type and name combination is used for multiple resource blocks, which is not allowed in Terraform. For example, resource "aws_instance" "example" {...} cannot be used more than once in the same configuration. Terraform validate does not report errors related to module versions, state differences, or formatting issues, as these are not relevant for checking the configuration syntax and structure. References = [Validate Configuration], [Resource Syntax]
NEW QUESTION # 35
Which of the following is not a valid Terraform collection type?
- A. Map
- B. set
- C. List
- D. Tree
Answer: D
Explanation:
Explanation
This is not a valid Terraform collection type, as Terraform only supports three collection types: list, map, and set. A tree is a data structure that consists of nodes with parent-child relationships, which is not supported by Terraform.
NEW QUESTION # 36
Terraform providers are part of the Terraform core binary.
- A. True
- B. False
Answer: B
Explanation:
Terraform providers are not part of the Terraform core binary. Providers are distributed separately from Terraform itself and have their own release cadence and version numbers. Providers are plugins that Terraform uses to interact with various APIs, such as cloud providers, SaaS providers, and other services. You can find and install providers from the Terraform Registry, which hosts providers for most major infrastructure platforms. You can also load providers from a local mirror or cache, or develop your own custom providers.
To use a provider in your Terraform configuration, you need to declare it in the provider requirements block and optionally configure its settings in the provider block. References = : Providers - Configuration Language | Terraform : Terraform Registry - Providers Overview | Terraform
NEW QUESTION # 37
terraform validate confirms that your infrastructure matches the Terraform state file.
- A. True
- B. False
Answer: B
Explanation:
terraform validate does not confirm that your infrastructure matches the Terraform state file. It only checks whether the configuration files in a directory are syntactically valid and internally consistent3. To confirm that your infrastructure matches the Terraform state file, you need to use terraform plan or terraform apply with the
-refresh-only option.
NEW QUESTION # 38
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 Terraform state file and execute terraform apply.
- B. The Terraform state file contains all 16 VMs in the team account. Execute terraform destroy and select the newly-created VM.
- C. The Terraform state file only contains the one new VM. Execute terraform destroy.
- D. Delete the VM using the cloud provider console and terraform apply to apply the changes to the Terraform state file.
Answer: C
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 # 39
Define the purpose of state in Terraform.
- A. State lets you enforce resource configurations that relate to compliance policies
- B. State codifies the dependencies of related resources
- C. State maps real world resources to your configuration and keeps track of metadata
- D. State stores variables and lets you quickly reuse existing code
Answer: C
Explanation:
The purpose of state in Terraform is to keep track of the real-world resources managed by Terraform, mapping them to the configuration. The state file contains metadata about these resources, such as resource IDs and other important attributes, which Terraform uses to plan and manage infrastructure changes. The state enables Terraform to know what resources are managed by which configurations and helps in maintaining the desired state of the infrastructure.
Reference = This role of state in Terraform is outlined in Terraform's official documentation, emphasizing its function in mapping configuration to real-world resources and storing vital metadata .
NEW QUESTION # 40
What is a key benefit of the Terraform state file?
- A. A state file can schedule recurring infrastructure tasks
- B. A state file is the desired state expressed by the Terraform code files
- C. A state file is a source of truth for resources provisioned with a public cloud console
- D. A state file is a source of truth for resources provisioned with Terraform
Answer: D
Explanation:
This is a key benefit of the Terraform state file, as it stores and tracks the metadata and attributes of the resources that are managed by Terraform, and allows Terraform to compare the current state with the desired state expressed by your configuration files.
NEW QUESTION # 41
Where does the Terraform local backend store its state?
- A. In the terraform file
- B. In the user's terraform,state file
- C. In the terraform,tfstate file
- D. In the /tmp directory
Answer: C
Explanation:
This is where the Terraform local backend stores its state, by default, unless you specify a different file name or location in your configuration. The local backend is the simplest backend type that stores the state file on your local disk.
NEW QUESTION # 42
You have a list of numbers that represents the number of free CPU cores on each virtual cluster:
What Terraform function could you use to select the largest number from the list?
- A. ceil (numcpus)
- B. max(numcpus)
- C. hight[numcpus]
- D. top(numcpus)
Answer: B
Explanation:
In Terraform, the max function can be used to select the largest number from a list of numbers. The max function takes multiple arguments and returns the highest one. For the list numcpus = [18, 3, 7, 11, 2], using max(numcpus...) will return 18, which is the largest number in the list.
Reference:
Terraform documentation on max function: Terraform Functions - max
NEW QUESTION # 43
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. After you start coding a new terraform project and before you run terraform plan for the first time.
- D. Every time you run terraform apply
Answer: C
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 = :
Initialize a Terraform Project
NEW QUESTION # 44
As a member of an operations team that uses infrastructure as code (lac) practices, you are tasked with making a change to an infrastructure stack running in a public cloud. Which pattern would follow laC best practices for making a change?
- A. Clone the repository containing your infrastructure code and then run the code
- B. Make the change programmatically via the public cloud CLI
- C. Make the change via the public cloud API endpoint
- D. Use the public cloud console to make the change after a database record has been approved
- E. Submit a pull request and wait for an approved merge of the proposed changes
Answer: E
Explanation:
Explanation
You do not need to use different Terraform commands depending on the cloud provider you use. Terraform commands are consistent across different providers, as they operate on the Terraform configuration files and state files, not on the provider APIs directly.
NEW QUESTION # 45
Which of the following arguments are required when declaring a Terraform output?
- A. description
- B. default
- C. sensitive
- D. value
Answer: D
Explanation:
When declaring a Terraform output, thevalueargument is required. Outputs are a way to extract information from Terraform-managed infrastructure, and thevalueargument specifies what data will be outputted. While other arguments likedescriptionandsensitivecan provide additional context or security around the output, valueis the only mandatory argument needed to define an output.References= The requirement of thevalue argument for outputs is specified in Terraform's official documentation, which provides guidelines on defining and using outputs in Terraform configurations.
NEW QUESTION # 46
Which command add existing resources into Terraform state?
- A. Terraform plan
- B. All of these
- C. Terraform import
- D. Terraform refresh
- E. Terraform init
Answer: C
Explanation:
This is the command that can add existing resources into Terraform state, by matching them with the corresponding configuration blocks in your files.
NEW QUESTION # 47
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. True
- B. False
Answer: B
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.
Reference = 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 # 48
Which of these commands makes your code more human readable?
- A. Terraform fmt
- B. Terraform validate
- C. Terraform show
- D. Terraform output
Answer: A
Explanation:
Explanation
The command that makes your code more human readable is terraform fmt. This command is used to rewrite Terraform configuration files to a canonical format and style, following the Terraform language style conventions and other minor adjustments for readability. The command is optional, opinionated, and has no customization options, but it is recommended to ensure consistency of style across different Terraform codebases. Consistency can help your team understand the code more quickly and easily, making the use of terraform fmt very important. You can run this command on your configuration files before committing them to source control or as part of your CI/CD pipeline. References = : Command: fmt : Using Terraform fmt Command to Format Your Terraform Code
NEW QUESTION # 49
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.
- A. True
- B. False
Answer: B
Explanation:
Explanation
The execution plan for terraform apply will not be the same as the one you ran locally with terraform plan, if your teammate manually modified the infrastructure component you are working on. This is because Terraform will refresh the state file before applying any changes, and will detect any differences between the state and the real resources.
NEW QUESTION # 50
Which of the following is not a valid source path for specifying a module?
- A. source = "./module?version=vl.6.0"
- B. source - "hashicorp/consul/aws"
- C. source - "./module"
- D. source - "github.com/hashicorp/examplePref-ul.0.8M
Answer: A
Explanation:
Terraform modules are referenced by specifying a source location. This location can be a URL or a file path.
However, specifying query parameters such as?version=vl.6.0directly within the source path is not a valid or supported method for specifying a module version in Terraform. Instead, version constraints are specified using theversionargument within the module block, not as part of the source string.References= This clarification is based on Terraform's official documentation regarding module usage, which outlines the correct methods for specifying module sources and versions.
NEW QUESTION # 51
A Terraform provider is NOT responsible for:
- A. Managing actions to take based on resources differences
- B. Understanding API interactions with some service
- C. Exposing resources and data sources based on an APUI
- D. Provisioning infrastructure in multiple
Answer: D
Explanation:
This is not a responsibility of a Terraform provider, as it does not make sense grammatically or logically. A Terraform provider is responsible for exposing resources and data sources based on an API, managing actions to take based on resource differences, and understanding API interactions with some service.
NEW QUESTION # 52
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. Vsphere_datacenter.dc.id
- C. Data.vsphere_datacenter.DC.id
- D. Data.vsphere_datacenter,dc
Answer: C
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. Reference = [Data Source: vsphere_datacenter], [Data Source: vsphere_folder], [Expressions: Data Source Reference]
NEW QUESTION # 53
When should you write Terraform configuration files for existing infrastructure that you want to start managing with Terraform?
- A. After you run terraform import
- B. Terraform will generate the corresponding configuration files for you
- C. You can import infrastructure without corresponding Terraform code
- D. Before you run terraform Import
Answer: D
Explanation:
You need to write Terraform configuration files for the existing infrastructure that you want to import into Terraform, otherwise Terraform will not know how to manage it. The configuration files should match the type and name of the resources that you want to import.
NEW QUESTION # 54
Only the user that generated a plan may apply it.
- A. True
- B. False
Answer: B
Explanation:
Explanation
Any user with permission to apply a plan can apply it, not only the user that generated it. This allows for collaboration and delegation of tasks among team members.
