Online Terraform-Associate-003 Questions Video

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.

From Terraform CLI Overview:

"Terraform provides a consistent CLI workflow regardless of which cloud or service you’re managing."

Thesame Terraform commandswork across all providers via plugins.

A Terraformbackenddetermineswhere and how Terraform state is stored.

Bothterraform applyandterraform destroyinteract with state, so Terraform needs access to the backend for state storage and updates.

D (Neither are correct)is incorrect becauseTerraform state is required for both apply and destroy operations.

Terraform Backends

Detailed Explanation:

Rationale for Correct Answer (D):The terraform.lock.hcl file is automatically created and maintained by Terraform. It records the specific versions and checksums of providers used in a configuration, ensuring consistent runs across environments and machines.

Analysis of Incorrect Options:

A. There is no such file: Incorrect — the lock file exists and is crucial for dependency management.

B. Storing references to workspaces: Incorrect — workspaces are tracked in the state file, not the lock file.

C. Preventing Terraform runs: Incorrect — the lock file does not block runs; it enforces consistent provider versions.

Key Concept:The terraform.lock.hcl file enforces provider version consistency, which is critical for reproducible and reliable Terraform deployments.

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.
