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.
Exhibit
Refer to the exhibit.
```hcl erraform {
required_version = ">= 1.0"
}
module "network" {
source = "./modules/networking"
vpc_id = "vpc-12345"
}
```
Output from `terraform plan`:
```
Error: Module not found
The module at "./modules/networking" could not be found.
```
What is the most likely cause of this error?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
Refer to the exhibit.

required_version = ">= 1.0"
}
module "network" {
source = "./modules/networking"
vpc_id = "vpc-12345"
}
```
Output from `terraform plan`:
```
Error: Module not found
The module at "./modules/networking" could not be found.
```
A
The module requires a version constraint.
Why wrong: Incorrect: version constraints are not applicable to local module paths.
B
The module source path does not exist.
Correct: the module directory './modules/networking' is missing.
C
The required_version is incompatible with the module.
Why wrong: Incorrect: the error is about module not found, not version compatibility.
D
The module input variable 'vpc_id' is not defined in the module.
Why wrong: Incorrect: a missing input variable would cause a different error about required variable.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The module source path does not exist.
Option C is correct because the error message indicates the module directory does not exist. Option A is incorrect because a version constraint is not relevant for local paths. Option B is incorrect because the required_version is satisfied. Option D is incorrect because the error is about module sourcing, not variable definition.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis

For each option: why learners choose it and why it is or isn't the right answer here.
✗
The module requires a version constraint.
Why it's wrong here
Incorrect: version constraints are not applicable to local module paths.
✓
The module source path does not exist.
Why this is correct
Correct: the module directory './modules/networking' is missing.
Clue confirmation

Related concept
Static NAT maps one inside address to one outside address.
✗
The required_version is incompatible with the module.
Why it's wrong here
Incorrect: the error is about module not found, not version compatibility.
✗
The module input variable 'vpc_id' is not defined in the module.
Why it's wrong here
Incorrect: a missing input variable would cause a different error about required variable.
Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related TF-003 NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: The module source path does not exist. — Option C is correct because the error message indicates the module directory does not exist. Option A is incorrect because a version constraint is not relevant for local paths. Option B is incorrect because the required_version is satisfied. Option D is incorrect because the error is about module sourcing, not variable definition.

Are there clue words in this question I should notice?
Yes — watch for: "most likely". Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
