Answer: A,C

Explanation:

The local-exec provisioner invokes a local executable after a resource is created. This invokes a process on the machine running Terraform, not on the resource.

Note that even though the resource will be fully created when the provisioner is run, there is no guarantee that it will be in an operable state – for example system services such as sshd may not be started yet on compute resources.

Example usage

resource "aws_instance" "web" {

# …

provisioner "local-exec" {

command = "echo ${aws_instance.web.private_ip} >> private_ips.txt"

}

}

Note: Provisioners should only be used as a last resort. For most common situations there

are better alternatives.
