HashiCorp Updated Terraform-Associate-003 Exam Questions and Answers by yasin

Sentinel is a policy-as-code framework that allows you to define and enforce rules on your Terraform configurations, states, and plans1. Some of the benefits of using Sentinel with Terraform Cloud/Terraform Enterprise are:

•You can restrict specific resource configurations, such as disallowing the use of CIDR=0.0.0.0/0, which would open up your network to the entire internet. This can help you prevent misconfigurations or security vulnerabilities in your infrastructure2.

•Policy-as-code can enforce security best practices, such as requiring encryption, authentication, or compliance standards. This can help you protect your data and meet regulatory requirements3.

•You can enforce a list of approved AWS AMIs, which are pre-configured images that contain the operating system and software you need to run your applications. This can help you ensure consistency, reliability, and performance across your infrastructure4.

Module Versioning: To specify a version in a module block for modules in theTerraform Registry, you add the version attribute, e.g., version = "1.0.0".

Terraform Registry Support: The public registrysupports versioningby enabling semantic constraints, allowing users to define specific versions compatible with their infrastructure requirements.

Refer to themodule versioning documentationin Terraform’s official registry guide.

Changes invoked by terraform apply take effect once the resource provider has fulfilled the request, not after Terraform has updated the state file or immediately. The state file is only a reflection of the real resources, not a source of truth.

Terraformis written in Go, but it isdistributed as a standalone binaryanddoes notrequire the Go runtime.

Users do not need to install Go to run Terraform.
