NEW QUESTION # 66
You cannot install third party plugins using terraform init.
- A. True
- B. False
Answer: B
Explanation:
Explanation
You can install third party plugins using terraform init, as long as you specify the plugin directory in your configuration or as a command-line argument. You can also use the terraform providers mirror command to create a local mirror of providers from any source.
NEW QUESTION # 67
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 is only arable lo paying customers
- D. It doesn't show the output of a terraform apply locally
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 # 68
You can reference a resource created with for_each using a Splat ( *) expression.
- A. True
- B. False
Answer: B
Explanation:
You cannot reference a resource created with for_each using a splat (*) expression, as it will not work with resources that have non-numeric keys. You need to use a for expression instead to iterate over the resource instances.
NEW QUESTION # 69
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:
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 # 70
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.

NEW QUESTION # 71
Terraform can only manage resource dependencies if you set them explicitly with the depends_on argument.
- A. True
- B. False
Answer: B
Explanation:
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. References = : Create resource dependencies : Terraform Resource Dependencies Explained
NEW QUESTION # 72
What is the name of the default file where Terraform stores the state?
Type your answer in the field provided. The text field is not case-sensitive and all variations of the correct answer are accepted.
- A. Terraformtfstate
Answer: A
Explanation:
The name of the default file where Terraform stores the state is terraform.tfstate. This file contains a JSON representation of the current state of the infrastructure managed by Terraform. Terraform uses this file to track the metadata and attributes of the resources, and to plan and apply changes. By default, Terraform stores the state file locally in the same directory as the configuration files, but it can also be configured to store the state remotely in a backend. Reference = [Terraform State], [State File Format]
NEW QUESTION # 73
What information does the public Terraform Module Registry automatically expose about published modules?
- A. Optional inputs variables and default values
- B. None of the above
- C. Outputs
- D. Required input variables
- E. All of the above
Answer: E
Explanation:
The public Terraform Module Registry automatically exposes all the information about published modules, including required input variables, optional input variables and default values, and outputs. This helps users to understand how to use and configure the modules.
NEW QUESTION # 74
You can develop a custom provider to manage its resources using Terraform.
- A. True
- B. False
Answer: A
Explanation:
You can develop a custom provider to manage its resources using Terraform, as Terraform is an extensible tool that allows you to write your own plugins in Go language. You can also publish your custom provider to the Terraform Registry or use it privately.
NEW QUESTION # 75
When you use a remote backend that needs authentication, HashiCorp recommends that you:
- A. Push your Terraform configuration to an encrypted git repository
- B. Keep the Terraform configuration files in a secret store
- C. Write the authentication credentials in the Terraform configuration files
- D. Use partial configuration to load the authentication credentials outside of the Terraform code
Answer: D
Explanation:
This is the recommended way to use a remote backend that needs authentication, as it allows you to provide the credentials via environment variables, command-line arguments, or interactive prompts, without storing them in the Terraform configuration files.
NEW QUESTION # 76
Once you configure a new Terraform backend with a terraform code block, which command(s) should you use to migrate the state file?
- A. terraform destroy, then terraform apply
- B. terraform apply
- C. terraform init
- D. terraform push
Answer: A
Explanation:
This command will initialize the new backend and prompt you to migrate the existing state file to the new location4. The other commands are not relevant for this task.
NEW QUESTION # 77
How can a ticket-based system slow down infrastructure provisioning and limit the ability to scale? Choose two correct answers.
- A. Users can access catalog of approved resources from drop down list in a request form
- B. Ticket based systems generate a full audit trail of the request and fulfillment process
- C. End-users have to request infrastructure changes
- D. The more resources your organization needs, the more tickets your infrastructure team has to process
Answer: C
Explanation:
Explanation
These are some of the ways that a ticket-based system can slow down infrastructure provisioning and limit the ability to scale, as they introduce delays, bottlenecks, and manual interventions in the process of creating and modifying infrastructure.
NEW QUESTION # 78
Which option cannot be used to keep secrets out of Terraform configuration files?
- A. A -var flag
- B. Environment variables
- C. A Terraform provider
- D. secure string
Answer: D
Explanation:
Explanation
A secure string is not a valid option to keep secrets out of Terraform configuration files. A secure string is a feature of AWS Systems Manager Parameter Store that allows you to store sensitive data encrypted with a KMS key. However, Terraform does not support secure strings natively and requires a custom data source to retrieve them. The other options are valid ways to keep secrets out of Terraform configuration files. A Terraform provider can expose secrets as data sources that can be referenced in the configuration.
Environment variables can be used to set values for input variables that contain secrets. A -var flag can be used to pass values for input variables that contain secrets from the command line or a file. References =

NEW QUESTION # 79
Which of the following statements about Terraform modules is not true?
- A. A module is a container for one or more resources
- B. You can call the same module multiple times
- C. Modules can call other modules
- D. Modules must be publicly accessible
Answer: D
Explanation:
This is not true, as modules can be either public or private, depending on your needs and preferences. You can use the Terraform Registry to publish and consume public modules, or use Terraform Cloud or Terraform Enterprise to host and manage private modules.
NEW QUESTION # 80
You want to define a single input variable to capture configuration values for a server. The values must represent memory as a number, and the server name as a string.
Which variable type could you use for this input?
- A. Map
- B. Terraform does not support complex input variables of different types
- C. List
- D. Object
Answer: D
Explanation:
This is the variable type that you could use for this input, as it can store multiple attributes of different types within a single value. The other options are either invalid or incorrect for this use case.
NEW QUESTION # 81
Setting the TF_LOG environment variable to DEBUG causes debug messages to be logged into stdout.
- A. True
- B. False
Answer: A
Explanation:
Explanation
Setting the TF_LOG environment variable to DEBUG causes debug messages to be logged into stdout, along with other log levels such as TRACE, INFO, WARN, and ERROR. This can be useful for troubleshooting or debugging purposes.
