Remote state data source in Terraform - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is a remote state data source in Terraform?

A remote state data source lets Terraform read the state file stored in a remote location. This helps share information between different Terraform configurations safely.

beginner

Why use remote state data source instead of local state?

Remote state allows multiple users or configurations to access the same infrastructure data. It prevents conflicts and keeps state consistent across teams.

intermediate

Which backend types can be used with remote state data source?

Common backends include AWS S3, Azure Blob Storage, Google Cloud Storage, and Terraform Cloud. These store state files remotely and securely.

intermediate

How do you reference a remote state in Terraform code?

You use the `terraform_remote_state` data source block with backend configuration to fetch outputs from another state file.

intermediate

What is a key benefit of using remote state data source for infrastructure dependencies?

It allows one Terraform configuration to depend on outputs from another, enabling modular and reusable infrastructure setups.

What does the Terraform remote state data source primarily provide?

A A tool to encrypt Terraform variables

B A way to store Terraform code remotely

C A method to run Terraform commands on a remote server

D Access to outputs from another Terraform state stored remotely

The remote state data source lets Terraform read outputs from a state file stored remotely.

Which backend is NOT commonly used for Terraform remote state?

A GitHub Repository

B Azure Blob Storage

C AWS S3

D Google Cloud Storage

GitHub Repository is not a backend for storing Terraform state files.

How do you declare a remote state data source in Terraform?

A Using the `backend` block inside a resource

B Using the `remote_state` resource block

C Using the `terraform_remote_state` data block

D Using the `state_file` variable

The `terraform_remote_state` data block is used to access remote state outputs.

What is a key advantage of remote state for teams?

A Allows multiple users to share consistent infrastructure data

B Automatically runs Terraform plans

C Encrypts all Terraform variables by default

D Generates Terraform code automatically

Remote state enables teams to share and coordinate infrastructure data safely.

What must you configure to use a remote state data source?

A Terraform provider for remote state

B Backend configuration with storage details

C A local state file path

D A remote execution environment

You must configure the backend with storage details to access remote state.

Explain how Terraform remote state data source helps in managing infrastructure dependencies.

Think about how one project can use information from another.
