Terraform_remote_state usage - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is Terraform remote state?

Terraform remote state is a way to store the state file in a shared location, so multiple users or systems can access and update the infrastructure state safely.

beginner

Why use remote state instead of local state in Terraform?

Remote state allows teams to collaborate without conflicts, keeps state secure, and supports locking to prevent simultaneous changes that could cause errors.

How do you reference remote state outputs in Terraform?

You use the terraform_remote_state data source to access outputs from another Terraform configuration's remote state, allowing you to use those values in your current configuration.

intermediate

What is state locking in Terraform remote state?

State locking prevents multiple users from making changes to the state at the same time, avoiding conflicts and corruption of the infrastructure state.

beginner

Name a common backend used for Terraform remote state storage.

Common backends include AWS S3 with DynamoDB for locking, Azure Blob Storage, Google Cloud Storage, and HashiCorp Consul.

What is the main benefit of using Terraform remote state?

A Automatically creates infrastructure without code

B Allows multiple users to safely share infrastructure state

C Makes Terraform run faster locally

D Removes the need for Terraform configuration files

Remote state allows safe sharing of infrastructure state among multiple users or systems.

Which Terraform feature helps prevent simultaneous state changes?

A State backup

B State encryption

C State versioning

D State locking

State locking prevents multiple users from changing the state at the same time.

How do you access outputs from a remote state in Terraform?

A Using terraform_output resource

B Using terraform_state variable

C Using terraform_remote_state data source

D Using terraform_import command

The terraform_remote_state data source is used to read outputs from remote state.

Which backend is commonly used with AWS for Terraform remote state?

A S3 with DynamoDB for locking

B Azure Blob Storage

C Google Cloud Storage

D Local file system

AWS S3 is used to store state files and DynamoDB provides locking support.

What happens if you do not use remote state in a team environment?

A State conflicts and overwrites may occur

B Terraform will run faster

C Infrastructure will be automatically updated

D Terraform will not create any resources

Without remote state, multiple users can overwrite each other's changes causing conflicts.

Explain how Terraform remote state helps teams work together on infrastructure.

Think about how multiple people can safely update the same project.

Describe the steps to use terraform_remote_state to access outputs from another Terraform configuration.

Focus on how to connect and use data from another state.
