Which Terraform command refreshes the state to align with real infrastructure?

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

Answer: (B)

State synchronization is about making Terraform's view of resources match what actually exists. The explicit refresh command asks Terraform to look at every resource defined in the configuration, query the live infrastructure, and update the local state accordingly. It doesn’t change any infrastructure by itself; it only aligns the state with reality. That makes it the best answer for refreshing the state. By contrast, planning creates a plan of what would change to reach the desired configuration (and, in most versions, it refreshes the state as part of that process but its primary job is to show potential changes). Applying carries out those changes to reach the desired state, and destroying removes resources. Note that in newer Terraform versions, a plan often refreshes automatically, but the explicit refresh command is designed specifically to sync the state with the real environment.
