Quick Answer
The correct answer is that module outputs are accessible from the root configuration using the syntax `module.<MODULE_NAME>.<OUTPUT_NAME>`. This is correct because Terraform modules encapsulate infrastructure resources and expose specific values through declared outputs, which the root module can then reference as attributes of the module resource. On the HashiCorp Terraform Associate TF-003 exam, this concept tests your understanding of how data flows between modules and the root configuration, often appearing in questions about referencing cross-module values or debugging “unknown resource” errors. A common trap is confusing module outputs with resource attributes or attempting to use `output` directly instead of the `module.` prefix. Remember the memory tip: “Module outputs are like public methods—you access them through the module object, not by calling the output name alone.”
TF-003 Interact with Terraform modules Practice Question
This TF-003 practice question tests your understanding of interact with terraform modules. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Which three of the following describe correct practices or behaviors when interacting with Terraform modules? (Choose three.)

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
A module source can be a local file path, such as './modules/networking'.
Option null is correct because Terraform modules can be sourced from a local file path using the `source` argument, such as `'./modules/networking'`, which allows referencing modules stored within the same repository or filesystem. This is a fundamental feature for organizing infrastructure code without relying on remote registries.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Common exam traps
Common exam trap: answer the scenario, not the keyword
HashiCorp often tests the misconception that modules can only come from the public Terraform Registry, but the exam expects you to know that local paths, Git repos, and HTTP URLs are also valid sources.
Detailed technical explanation
How to think about this question
Under the hood, Terraform's module system uses a `source` attribute that supports various protocols, including local filesystem paths, Git over HTTPS/SSH, Mercurial, and HTTP archives. When a module is sourced from a Git repository, Terraform clones the repository into `.terraform/modules` and uses the specified ref (branch, tag, or commit) to lock the version, ensuring reproducibility; any manual changes inside that directory are ignored and overwritten on subsequent initialization. This behavior is critical in CI/CD pipelines where consistency across environments depends on immutable module sources.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
