HashiCorp Certified: Terraform Associate (003) — Question 32

Which of these actions will prevent two Terraform runs from changing the same state file at the same time?

Answer options

• A. Delete the state before running Terraform.
• B. Refresh the state after running Terraform.
• C. Run Terraform with parallelism set to 1.
• D. Configure state locking for your state backend.

Correct answer: D

Explanation

The correct answer is D because configuring state locking prevents concurrent operations on the same state file, ensuring that only one process can modify it at a time. Options A and B do not address concurrent access, and option C limits parallelism but does not provide a safeguard against overlapping runs.
