Exam Terraform Associate topic 1 question 40 discussion

C correct answer Version When using modules installed from a module registry, we recommend explicitly constraining the acceptable version numbers to avoid unexpected or unwanted changes. Use the version argument in the module block to specify versions: module "consul" { source = "hashicorp/consul/aws" version = "0.0.5" servers = 3 }

CCCCCC

Example: module "consul" { source = "hashicorp/consul/aws" version = "1.0.0" // other necessary arguments... }

Although please note that version is now deprecated in favour of the required_providers block https://developer.hashicorp.com/terraform/language/providers/configuration#version-deprecated

C is the correct answer. It is used to lock down version of the modules in production grade infrastructure templates.

C is correct

example from HashiCorp: module "consul" { source = "hashicorp/consul/aws" version = "0.0.5" servers = 3 }

C is correct answer. The version argument accepts a version constraint string. Terraform will use the newest installed version of the module that meets the constraint; if no acceptable versions are installed, it will download the newest version that meets the constraint. Version constraints are supported only for modules installed from a module registry, such as the public Terraform Registry or Terraform Cloud's private module registry. Other module sources can provide their own versioning mechanisms within the source string itself, or might not support versions at all. In particular, modules sourced from local file paths do not support version; since they're loaded from the same source repository, they always share the same version as their caller. https://www.terraform.io/language/modules/syntax#version
