  output "db_password"

  2.

  {

  3.

• Question 263:

  What kind of resource dependency is stored in terraform.tfstate file?

  A. Both implicit and explicit dependencies are stored in state file.

  B. Only explicit dependencies are stored in state file.

  C. Only implicit dependencies are stored in state file.

  D. No dependency information is stored in state file.

  Correct Answer: A

  Terraform state captures all dependency information, both implicit and explicit. One purpose for state is to determine the proper order to destroy resources. When resources are created all of their dependency information is stored in the state. If you destroy a resource with dependencies, Terraform can still determine the correct destroy order for all other resources because the dependencies are stored in the state.

• Question 268:

  A single terraform resource file that defines an aws_instance resource can simply be renamed to vsphere_virtual_machine in order to switch cloud providers.

  A. True

  B. False

  Correct Answer: B

  Which flag would be used within a Terraform configuration block to identify the specific version of a provider required?

  A. required-provider

  terraform {

  required_providers {

  aws = ">= 2.7.0"

  }

  }
