What is a "Mock Output"?

A placeholder value used when a dependency is not yet deployed

A way to provide humorous feedback in the terminal

A fake error message used to test the failure logic

A tool for testing the responsiveness of the web UI

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

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 create a new environment tier in the cloud

To permanently delete a file from the host machine

What is "Prevent Destroy"?

A flag that prevents the accidental deletion of a module
