HashiCorp Certified: Terraform Associate — Question 102

You want to tag multiple resources with a string that is a combination of a generated random_id and a variable.

How should you use the same value in all these resources without repeating the random_id and variable in each resource?

Answer options

• A. Local values
• B. Data source
• C. Modules
• D. Outputs

Correct answer: A

Explanation

The correct answer is A, Local values, because they allow you to define a value once and reference it multiple times within your configuration, eliminating redundancy. Options B (Data source), C (Modules), and D (Outputs) do not serve the same purpose; data sources retrieve information, modules encapsulate resources, and outputs are used to display results after execution.
