Question

In order to reduce the time it takes to provision resources, Terraform uses parallelism. By default, how many resources will Terraform provision concurrently?

Options

Explanation

Terraform's default parallelism is 10, meaning it provisions up to 10 resource instances concurrently during a plan or apply operation.

Common mistakes.

A. 5 is not the default parallelism value; Terraform uses 10 concurrent resource operations out of the box.
B. 50 concurrent operations is not the default and could overwhelm provider API rate limits; it is not Terraform's out-of-the-box behavior.
D. 20 is not the default parallelism value for Terraform resource provisioning.
