NEW QUESTION # 46
You must use different Terraform commands depending on the cloud provider you use.
- A. True
- B. False
Answer: B
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 # 47
_______backends support state locking.
- A. Some
- B. No
- C. All
- D. Only local
Answer: A
Explanation:
Some backends support state locking, which prevents other users from modifying the state file while a Terraform operation is in progress. This prevents conflicts and data loss. Not all backends support this feature, and you can check the documentation for each backend type to see if it does.
NEW QUESTION # 48
You ate creating a Terraform configuration which needs to make use of multiple providers, one for AWS and one for Datadog.
Which of the following provider blocks would allow you to do this?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
Option C is the correct way to configure multiple providers in a Terraform configuration. Each provider block must have a name attribute that specifies which provider it configures2. The other options are either missing the name attribute or using an invalid syntax.
NEW QUESTION # 49
Which two steps are required to provision new infrastructure in the Terraform workflow? Choose two correct answers.
- A. Alidate
- B. Plan
- C. apply
- D. Import
- E. Init
Answer: C,E
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 containing Terraform 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. Reference = [The Core Terraform Workflow], [Initialize a Terraform working directory with init], [Apply Terraform Configuration with apply]
NEW QUESTION # 50
You want to know from which paths Terraform is loading providers referenced in your Terraform configuration (* files). You need to enable additional logging messages to find this out.
Which of the following would achieve this?
- A. Set the environment variable TF_LOG_PATH
- B. Set verbose for each provider in your Terraform configuration
- C. Set the environment variable TF_log_TRACE
- D. Set the environment variable TF_LOG_TRACE
Answer: D
Explanation:
This will enable additional logging messages to find out from which paths Terraform is loading providers referenced in your Terraform configuration files, as it will set the log level to TRACE, which is the most verbose and detailed level.
NEW QUESTION # 51
Which of the following is not a valid siring function in Terraform?
- A. join
- B. slice
- C. choaf
- D. Split
Answer: C
Explanation:
This is not a valid string function in Terraform. The other options are valid string functions that can manipulate strings in various ways2.
NEW QUESTION # 52
How would you output returned values from a child module in the Terraform CLI output?
- A. Declare the output in both the root and child module
- B. Declare the output in the child module
- C. Declare the output in the root configuration
- D. None of the above
Answer: A
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. Reference = [Terraform Outputs]
NEW QUESTION # 53
A terraform apply can not _________ infrastructure.
- A. destroy
- B. import
- C. provision
- D. change
Answer: B
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. Reference = [Importing Infrastructure]
NEW QUESTION # 54
Which of these ate features of Terraform Cloud? Choose two correct answers.
- A. A web-based user interface (Ul)
- B. Automatic backups
- C. Remote state storage
- D. Automated infrastructure deployment visualization
Answer: A,C
Explanation:
These are features of Terraform Cloud, which is a hosted service that provides a web-based UI, remote state storage, remote operations, collaboration features, and more for managing your Terraform infrastructure.
NEW QUESTION # 55
Which task does terraform init not perform?
- A. Validates all required variables are present
- B. Connects to the backend
- C. Sources all providers used in the configuration and downloads them
- D. Sources any modules and copies the configuration locally
Answer: A
Explanation:
The terraform init command is used to initialize a working directory containing Terraform configuration files. This command performs several different initialization steps to prepare the current working directory for use with Terraform, which includes initializing the backend, installing provider plugins, and copying any modules referenced in the configuration. However, it does not validate whether all required variables are present; that is a task performed by terraform plan or terraform apply1.
Reference = This information can be verified from the official Terraform documentation on the terraform init command provided by HashiCorp Developer1.
NEW QUESTION # 56
You have multiple team members collaborating on infrastructure as code (IaC) using Terraform, and want to apply formatting standards for readability.
How can you format Terraform HCL (HashiCorp Configuration Language) code according to standard Terraform style convention?
- A. Write a shell script to transform Terraform files using tools such as AWK, Python, and sed
- B. Designate one person in each team to review and format everyone's code
- C. Manually apply two spaces indentation and align equal sign "=" characters in every Terraform file (*.tf)
- D. Run the terraform fmt command during the code linting phase of your CI/CD process Most Voted
Answer: D
Explanation:
The terraform fmt command is used to rewrite Terraform configuration files to a canonical format and style. This command applies a subset of the Terraform language style conventions, along with other minor adjustments for readability. Running this command on your configuration files before committing them to source control can help ensure consistency of style between different Terraform codebases, and can also make diffs easier to read. You can also use the -check and -diff options to check if the files are formatted and display the formatting changes respectively2. Running the terraform fmt command during the code linting phase of your CI/CD process can help automate this process and enforce the formatting standards for your team. Reference = [Command: fmt]2
NEW QUESTION # 57
Which of the following is not a key principle of infrastructure as code?
- A. Golden images
- B. Idempotence
- C. Self-describing infrastructure
- D. Versioned infrastructure
Answer: A
Explanation:
The key principle of infrastructure as code that is not listed among the options is golden images. Golden images are pre-configured, ready-to-use virtual machine images that contain a specific set of software and configuration. They are often used to create multiple identical instances of the same environment, such as for testing or production. However, golden images are not a principle of infrastructure as code, but rather a technique that can be used with or without infrastructure as code.
The other options are all key principles of infrastructure as code, as explained below:
Self-describing infrastructure: This means that the infrastructure is defined in code that describes its desired state, rather than in scripts that describe the steps to create it. This makes the infrastructure easier to understand, maintain, and reproduce.
Idempotence: This means that applying the same infrastructure code multiple times will always result in the same state, regardless of the initial state. This makes the infrastructure consistent and predictable, and avoids errors or conflicts caused by repeated actions.
Versioned infrastructure: This means that the infrastructure code is stored in a version control system, such as Git, that tracks the changes and history of the code. This makes the infrastructure code reusable, auditable, and collaborative, and enables practices such as branching, merging, and rollback.
Reference = [Introduction to Infrastructure as Code with Terraform], [Infrastructure as Code in a Private or Public Cloud]
NEW QUESTION # 58
What is one disadvantage of using dynamic blocks in Terraform?
- A. They cannot be used to loop through a list of values
- B. They make configuration harder to read and understand
- C. Terraform will run more slowly
- D. Dynamic blocks can construct repeatable nested blocks
Answer: B
Explanation:
This is one disadvantage of using dynamic blocks in Terraform, as they can introduce complexity and reduce readability of the configuration. The other options are either advantages or incorrect statements.
NEW QUESTION # 59
How is terraform import run?
- A. All of the above
- B. By an explicit call
- C. As a part of terraform init
- D. As a part of terraform refresh
- E. As a part of terraform plan
Answer: B
Explanation:
The terraform import command is not part of any other Terraform workflow. It must be explicitly invoked by the user with the appropriate arguments, such as the resource address and the ID of the existing infrastructure to import. Reference = [Importing Infrastructure]
NEW QUESTION # 60
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 # 61
One remote backend configuration always maps to a single remote workspace.
- A. False
- B. True
Answer: B
Explanation:
The remote backend can work with either a single remote Terraform Cloud workspace, or with multiple similarly-named remote workspaces (like networking-dev and networking-prod). The workspaces block of the backend configuration determines which mode it uses. To use a single remote Terraform Cloud workspace, set workspaces.name to the remote workspace's full name (like networking-prod). To use multiple remote workspaces, set workspaces.prefix to a prefix used in all of the desired remote workspace names. For example, set prefix = "networking-" to use Terraform cloud workspaces with names like networking-dev and networking-prod. This is helpful when mapping multiple Terraform CLI workspaces used in a single Terraform configuration to multiple Terraform Cloud workspaces3. However, one remote backend configuration always maps to a single remote workspace, either by name or by prefix. You cannot use both name and prefix in the same backend configuration, or omit both. Doing so will result in a configuration error3. Reference = [Backend Type: remote]3
NEW QUESTION # 62
Running terraform fmt without any flags in a directory with Terraform configuration files check the formatting of those files without changing their contents.
- A. True
- B. False
Answer: B
Explanation:
Running terraform fmt without any flags in a directory with Terraform configuration files will not check the formatting of those files without changing their contents, but will actually rewrite them to a canonical format and style. If you want to check the formatting without making changes, you need to use the - check flag.
