Which Terraform command updates provider plugins to the latest acceptable versions?

• A. terraform plan -upgrade
• B. terraform refresh -upgrade
• C. terraform apply -upgrade
• D. terraform init -upgrade

Answer: (D)

The key idea is how Terraform fetches and updates provider plugins. When you initialize a configuration, Terraform downloads the providers defined in your setup. To bring in newer provider versions that still fit your specified constraints, you run the initialization with the upgrade option. This tells Terraform to check for newer provider versions within the constraints in your required_providers blocks and update the installed plugins (and the lock file) accordingly. Other commands like plan, refresh, and apply don’t fetch or upgrade providers—they operate on the current plan and state using whatever plugins are already installed. So using the init command with the upgrade flag is the mechanism to update provider plugins to the latest acceptable versions.
