Which statement describes the timing of state updates in Terraform when planning or applying changes?

• A. Immediately updates the state during the next plan or apply
• B. State is not updated by Terraform at all
• C. State is refreshed only by manual edits
• D. Updates during the next plan or apply

Answer: (D)

Terraform keeps a state file that represents your real infrastructure. Before planning changes, it refreshes that state from the actual resources so the plan is based on what exists now. After a successful apply, it writes the updated state back to the state file (or backend) to reflect the new reality. So state updates occur as part of the next plan (via refresh) and are definitely written during the apply. That's why this description matches how Terraform manages state: it is updated during the plan phase to reflect current reality, and then updated again after applying changes to record the new reality.
