terraform state list - HashiCorp Documentation

Terraform Cloud provides features like remote state storage and a web-based user interface for managing your Terraform runs. While it offers robust infrastructure as code capabilities, automatic backups of configuration and state are not directly provided by Terraform Cloud; instead, the state is stored remotely and secured.

Speculative Plans: Terraform Cloud’sspeculative planfeature runs automatically when changes are detected in a linked VCS repository, enabling users to review potential infrastructure changes without committing them.

Automatic Integration: This feature automates the planning process by triggering when changes are committed, aiding teams in previewing infrastructure changes seamlessly.

For further understanding, see theTerraform Cloud VCS Integrationdocumentation.

E (✅Correct)–IaC aims to eliminate manual cloud console workflowsby using code-based automation.

A, B, C (✅Advantages of IaC)– IaC enablesself-service deployment, API-driven workflows, and dynamic resource scaling.

D (diff command)– While useful, troubleshooting via diff is not acore advantageof IaC.

What is Infrastructure as Code?

The terraform taint command marks a resource as tainted, which means it will be destroyed and recreated on the next apply. This way, you can replace the VM instance without affecting the database or other resources. References = [Terraform Taint]

Environment variables and connection configurations outside of Terraform are secure options for storing secrets for connecting to a Terraform remote backend. Environment variables can be used to set values for input variables that contain secrets, such as backend access keys or tokens. Terraform will read environment variables that start with TF_VAR_ and match the name of an input variable. For example, if you have an input variable called backend_token, you can set its value with the environment variable TF_VAR_backend_token1. Connection configurations outside of Terraform are files or scripts that provide credentials or other information for Terraform to connect to a remote backend. For example, you can use a credentials file for the S3 backend2, or a shell script for the HTTP backend3. These files or scripts are not part of the Terraform configuration and can be stored securely in a separate location. The other options are not secure for storing secrets. A variable file is a file that contains values for input variables. Variable files are usually stored in the same directory as the Terraform configuration or in a version control system. This exposes the secrets to anyone who can access the files or the repository. You should not store secrets in variable files1. Inside the backend block within the Terraform configuration is where you specify the type and settings of the remote backend. The backend block is part of the Terraform configuration and is usually stored in a version control system. This exposes the secrets to anyone who can access the configuration or the repository. You should not store secrets in the backend block4. References = [Terraform Input Variables]1, [Backend Type: s3]2, [Backend Type: http]3, [Backend Configuration]4

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.

Running terraform fmt without any flags in a directory with Terraform configuration files will not check the formatting of those files without changing their contents, but will actually rewrite them to a canonical format and style. If you want to check the formatting without making changes, you need to use the -check flag.
