Recall & Review

beginner

What is the main purpose of outputs in Terraform?

Outputs in Terraform show important information after deployment, like IP addresses or URLs, so you can use or share them easily.

beginner

How can outputs help as documentation in Terraform?

Outputs describe key values your infrastructure creates, making it clear what resources are available and how to connect to them.

beginner

Which Terraform block is used to define an output?

The `output` block defines an output value with a name and description.

beginner

Why should you add a description to Terraform outputs?

Descriptions explain what the output means, helping others understand the infrastructure without guessing.

intermediate

Can Terraform outputs be used by other Terraform configurations?

Yes, outputs can be shared and used as inputs in other Terraform projects, enabling modular and connected infrastructure.

What Terraform block do you use to show a value after deployment?

A provider

B variable

C resource

D output

The `output` block is used to display values after Terraform applies changes.

Why add a description to an output in Terraform?

A To hide the output value

B To explain the output's meaning

C To change the output value

D To delete the output

Descriptions help users understand what the output represents.

Which of these is NOT a good use of Terraform outputs?

A Storing sensitive passwords in plain text

B Showing server IP addresses

C Sharing resource IDs with other configs

D Displaying URLs of deployed services

Sensitive data should be handled carefully, not exposed in plain text outputs.

How do outputs help with documentation?

A They list important info about deployed resources

B They delete unused resources

C They speed up deployment

D They encrypt data

Outputs provide clear info about what your infrastructure created.

Can outputs be used as inputs in other Terraform projects?

A Only if they are strings

B No, outputs are only for display

C Yes, to connect different configurations

D Only if they are numbers

Outputs can be passed as inputs to other Terraform configurations for modular design.
