The terraform import command is used to import existing infrastructure into your Terraform state. This command takes the existing resource and associates it with a resource defined in your Terraform configuration, updating the state file accordingly. It does not generate configuration for the resource, only the state.

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. References = [Importing Infrastructure]

The Terraform binary version and provider versions do not have to match each other in a single configuration. Terraform allows you to specify provider version constraints in the configuration’s terraform block, which can be different from the Terraform binary version1. Terraform will use the newest version of the provider that meets the configuration’s version constraints2. You can also use the dependency lock file to ensure Terraform is using the correct provider version3. References =

Module version is optional to reference a module on the Terraform Module Registry. If you omit the version constraint, Terraform will automatically use the latest available version of the module

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.

Detailed Explanation:

Rationale for Correct Answer (C):Best practice is to avoid hardcoding sensitive credentials in Terraform configurations or storing them in version control. Instead, credentials should be managed via environment variables, CLI authentication helpers, or secret managers (e.g., Vault).

Analysis of Incorrect Options:

A. Shared server: Not secure, introduces single point of failure and risk.

B. Storing credentials in config files: A major security risk, especially if pushed to version control.

D. None of the above: Incorrect, because option C is a valid and recommended approach.

Key Concept:Security best practices in Terraform dictate that credentials should be externalized from Terraform code.

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.

This is the correct way to reference the volume IDs associated with the ebs_block_device blocks in this configuration, using the splat expression syntax. The other options are either invalid or incomplete.

Purpose of Refresh-Only Mode: Running Terraform inrefresh-only modeupdates Terraform's state file with the current state of resources in your infrastructure without making changes to the resources themselves.

Context of Terraform Import: When usingterraform import, you’re adding existing resources to the state file, and running Terraform in refresh-only mode before this operation can ensure that any initial configuration syncs precisely with the actual state.

For more on refresh-only mode in relation to terraform import, refer to Terraform's import documentation.

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.
