question 16 should be b (changing the connector settings on the monitor) pc and monitor were powered on. the lights on the pc are on indicating power. the monitor is showing an error text indicating that it is receiving power too. this is a clear sign of having the wrong input selected on the monitor. thus, the "connector setting" needs to be switched from hdmi to display port on the monitor so it receives the signal from the pc, or the other way around (display port to hdmi).

question 14 - run terraform import: this is the recommended best practice for bringing manually created or destroyed resources under terraform management. you use terraform import to associate an existing resource with a terraform resource configuration. this ensures that terraform is aware of the resource, and you can subsequently manage it with terraform.
