Which command should you run to preview changes Terraform would apply without applying them?

• A. terraform apply
• B. terraform plan
• C. terraform refresh
• D. terraform destroy

Answer: (B)

Previewing what Terraform will do is accomplished with the plan command. It compares your configuration to the current state and determines the exact actions needed to reach the desired state, showing you which resources will be created, changed, or destroyed. Importantly, no real changes are made when you run this command, so it’s safe to review the proposed changes first. You can also save the plan with -out to apply it later, ensuring you apply exactly what you preview. The other commands don’t serve this purpose: applying would execute the changes immediately, refreshing updates the state from real infrastructure without presenting a plan, and destroying would remove resources rather than simply showing what would happen.
