Pass the HashiCorp Terraform Associate Terraform-Associate-003 Questions and answers with CertsForce

Detailed Explanation:

Rationale for Correct Answer (B):Terraform interacts with external systems through providers. Since this is a new proprietary service with its own API, Terraform does not support it by default. You would need to develop a custom provider that implements Terraform’s provider interface and interacts with the proprietary APIs to manage resources like users.

Analysis of Incorrect Option:

A. Any service hosted on a public cloud provider: Not true. Terraform can only manage services that have providers (official or custom). Just being "hosted on a public cloud" doesn’t guarantee Terraform support.

Key Concept:Terraform providers act as the bridge between Terraform and external APIs. For unsupported services, a custom provider must be developed.

Terraformdownloads modules and providersinto the .terraform directory inside the working directory.

A (/tmp/)– Incorrect; modules arenot stored temporarily.

C (In memory)– Incorrect; modules persist on disk.

D (Not cached)– Incorrect; Terraformdoes cache modulesfor efficiency.

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. References = [The Core Terraform Workflow], [Initialize a Terraform working directory with init], [Apply Terraform Configuration with apply]

This is the Terraform style convention for indenting a nesting level compared to the one above it. The other options are not consistent with the Terraform style guide.

The correct syntax to pass a variable from the root module to a child module isservers = var.num_servers. Terraform uses dot notation to reference variables.

terraform apply can runwithout explicitly running terraform plan first.

Running terraform plan before apply isrecommendedbutnot mandatory.

If no plan file is provided, terraform applyautomatically creates and executes a planbefore applying changes.

This is how Terraform manages most dependencies between resources, by using the references between them in the configuration files. For example, if resource A depends on resource B, Terraform will create resource B first and then pass its attributes to resource A.

When the state file is locked, operations that modify or depend on the state (liketerraform apply,terraform destroy, andterraform state list) are blocked.terraform fmtonly formats the configuration files and does not interact with the state, so it is allowed.

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.

This command will check if all code in a Terraform configuration that references multiple modules is properly formatted without making changes, and will return a non-zero exit code if any files need formatting. The other commands will either make changes, list the files that need formatting, or not check the modules.
