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.6.0 directly within the source path is not a valid or supported method for specifying a module version in Terraform. Instead, version constraints are specified using the version argument 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.

Detailed Explanation:

Rationale for Correct Answer (B):terraform import allows Terraform to associate existing resources (created outside of Terraform or by another tool) with a Terraform configuration by writing them into the state file. After import, Terraform can manage those resources.

Analysis of Incorrect Options:

A. From one state file to another: Incorrect, import does not transfer between state files.

C. Importing a module: Incorrect, modules are defined in configuration, not imported.

D. Import all infrastructure: Incorrect, import is per-resource, not bulk.

E. Provider configuration transfer: Incorrect, provider configs are in .tf files, not imported with this command.

Key Concept:The terraform import command bridges existing resources with Terraform state management.

Child modulesdo not automatically inheritvariables from the parent module.

To pass values from theparent moduleto thechild module, you mustexplicitly define input variablesin the child module and pass them in the parent module.

Example:

hcl

CopyEdit

module "example" {

source = "./child_module"

var1 = "value"

}

Passing Variables to Modules

The terraform fmt command is used to format Terraform configuration files to a canonical format and style. This ensures that all team members are using a consistent style, making the code easier to read and maintain. It automatically applies Terraform's standard formatting conventions to your configuration files, helping maintain consistency across the team's codebase.

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.

Detailed Explanation:

Rationale for Correct Answer (True):When terraform apply completes successfully, Terraform prints output values. Outputs from both root and child modules are displayed, but child module outputs must be explicitly exposed through the root module outputs to be visible at the CLI.

Analysis of Incorrect Option:

False: Incorrect, because Terraform does display output values, but only if they are exposed from child modules to the root module.

Key Concept:Outputs help you extract important information (e.g., IP addresses, resource IDs) from your configuration.

All of the statements are true of Terraform providers. Terraform providers are plugins that enable Terraform to interact with various APIs and services1. Anyone can write a Terraform provider, either as an individual or as part of a community2. HashiCorp maintains some providers, such as the AWS, Azure, and Google Cloud providers3. Cloud providers and infrastructure vendors can also write, maintain, or collaborate on Terraform providers, such as the VMware, Oracle, and Alibaba Cloud providers. References =

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

You should run terraform fmt to rewrite all Terraform configurations within the current working directory to conform to Terraform-style conventions. This command applies a subset of the Terraform language style conventions, along with other minor adjustments for readability. It is recommended to use this command to ensure consistency of style across different Terraform codebases. The command is optional, opinionated, and has no customization options, but it can help you and your team understand the code more quickly and easily. References = : Command: fmt : Using Terraform fmt Command to Format Your Terraform Code

This is the method for sharing Terraform configurations that fulfills the following criteria:

Keeps the configurations confidential within your organization

Supports Terraform’s semantic version constraints

Provides a browsable directory

The Terraform Cloud private registry is a feature of Terraform Cloud that allows you to host and manage your own modules within your organization, and use them in your Terraform configurations with versioning and access control.
