Which command is used to apply changes required to reach the desired state?

• A. terraform apply
• B. terraform commit
• C. terraform execute
• D. terraform update

Answer: (A)

The command used to apply changes required to reach the desired state in Terraform is "terraform apply". This command reads the configuration files in the current directory, determines the necessary changes to the infrastructure to match the defined configuration, and then executes those changes. It prompts the user for confirmation before making any changes, allowing an opportunity to review the planned actions. This functionality is fundamental to Terraform's operation, as it ensures that the infrastructure reflects the desired state specified in the code. Upon successful execution, Terraform updates its state file to record the new infrastructure configuration. The other commands, while they might sound relevant, do not serve the purpose of applying changes. "terraform commit" is not a recognized command in Terraform's toolkit; "terraform execute" does not exist as a command, and "terraform update" is also not an official command within Terraform. Understanding the correct command is essential for effectively managing infrastructure changes with Terraform.
