Quick Answer
The answer is to enable cost estimation in Terraform Cloud. This is correct because Terraform Cloud offers a built-in cost estimation feature that analyzes the resources defined in your plan against current cloud provider pricing data, providing an estimated monthly cost before you apply any changes. On the HashiCorp Terraform Associate TF-003 exam, this question tests your understanding of Terraform Cloud’s native capabilities versus manual or external tools; a common trap is assuming you need a separate third-party service or that the terraform plan command itself includes cost data, which it does not. Remember that cost estimation is a Terraform Cloud workspace feature, not a CLI function, and it appears as a tab after a plan is run. A simple memory tip: “Cloud costs, Cloud checks” — if you need cost estimation, think of Terraform Cloud’s built-in analysis, not manual spreadsheets or external scripts.
This TF-003 practice question tests your understanding of use terraform outside the core workflow. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
A company has a Terraform configuration that creates many AWS resources. They want to check the estimated cost of the plan before applying. Which approach should they use?
Use 'terraform plan -cost' command.
Why wrong: No such command exists.
Manually use 'terraform show -json' and parse pricing.
Why wrong: This is possible but not a built-in feature.
Enable cost estimation in Terraform Cloud.
Terraform Cloud can estimate costs for AWS resources.
Use 'terraform validate' with a custom script.
Why wrong: Validate does not check costs.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Enable cost estimation in Terraform Cloud.
Option A is correct because Terraform Cloud provides cost estimation as a built-in feature. Options B and D are not available. Option C is a manual analysis but not a built-in feature.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Use 'terraform plan -cost' command.
Why it's wrong here
No such command exists.
Manually use 'terraform show -json' and parse pricing.
Why it's wrong here
This is possible but not a built-in feature.
Enable cost estimation in Terraform Cloud.
Why this is correct
Terraform Cloud can estimate costs for AWS resources.

Common exam traps
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Trap categories for this question
Command / output trap
No such command exists.
Detailed technical explanation
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A practitioner preparing for the TF-003 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
