How do you tell Terragrunt to use a specific version of Terraform?

terraform_version_constraint = ">= 1.0.0"

require_terraform { version = "1.0.0" }

What does the "--terragrunt-non-interactive" flag do?

It assumes a "yes" response to all interactive prompts

It suppresses all terminal output and logs

It reduces the execution speed of the deployment

It disables all network connections to the cloud

What is the "get_env()" function used for?

To retrieve environment variables from the host system

To query the current weather in the server region

To permanently delete a file from the host machine

What is "Prevent Destroy"?

A flag that prevents the accidental deletion of a module

A hardware-level safeguard against fire damage

A command that destroys everything except databases

How do you pass extra arguments to Terraform via Terragrunt?

extra_arguments "custom" { arguments = ["-lock=false"] }

terraform_flags = ["-lock=false"]

run_terraform --with-flags="-lock=false"

What is the purpose of "skip = true" in a Terragrunt configuration?

To ignore a directory during "run-all" executions
