What command can you use to create an execution plan in Terraform?

The command used to create an execution plan in Terraform is "terraform plan." This command is essential in the Terraform workflow as it allows users to see what changes will be made to their infrastructure before they are actually applied. When executing "terraform plan," Terraform compares the current state of the infrastructure with the desired state defined in the configuration files. It then outputs a detailed preview of the actions it will take, such as creating, updating, or destroying resources.

Using this command is a best practice, as it provides an opportunity to review the planned changes, ensuring that everything aligns with expectations. This step helps prevent unintentional modifications or disruptions in the infrastructure, increasing confidence in the deployment process.

The other choices are not valid commands for creating an execution plan. "terraform apply" is used to apply the changes defined in the configuration files. "terraform execute" is not a valid Terraform command, and "terraform preview" does not exist within the Terraform command set. Thus, understanding the purpose and functionality of "terraform plan" is critical for effectively managing infrastructure as code.
