• Question 64:

  You wanted to destroy some of the dependent resources from real infrastructure. You choose to delete those resources from your configuration file and run terraform plan and then apply. Which of the following way your resources would be destroyed?

  A. Terraform can still determine the correct order for destruction from the state even when you delete one or more items from the configuration.

  B. Those would be destroyed in the order in which they were written in the configuration file previously before you have deleted them from configuration file.

  C. The resource will be destructed in random order as you have already deleted them from configuration.

  D. You can not destroy resources by deleting them from configuration file and running plan and apply.

  Correct Answer: A

  Terraform typically uses the configuration to determine dependency order. However, when you delete a resource from a Terraform configuration, Terraform must know how to delete that resource. Terraform can see that a mapping exists for a resource not in your configuration and plan to destroy. However, since the configuration no longer exists, the order cannot be determined from the configuration alone. To ensure correct operation, Terraform retains a copy of the most recent set of dependencies within the state. Now Terraform can still determine the correct order for destruction from the state when you delete one or more items from the configuration.
