TF-003 Use Terraform outside the core workflow Practice Question
This TF-003 practice question tests your understanding of use terraform outside the core workflow. 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 TWO of the following are valid ways to pass variables to Terraform in an automated pipeline?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Creating a .tfvars file and referencing it with -var-file.
Option A is correct because `-var-file` allows you to pass a `.tfvars` file containing variable definitions, which is ideal for automated pipelines where you want to load multiple variables from a version-controlled or dynamically generated file without manual interaction. This approach supports repeatable, non-interactive deployments.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Creating a .tfvars file and referencing it with -var-file.
Why this is correct
Allows multiple variables in file.
Related concept
Read the scenario before looking for a memorised answer.
✗
Using interactive prompts during terraform apply.
Why it's wrong here
Prompts require human interaction.
✓
Using the -var flag to specify individual variables.
Why this is correct
Common in automation scripts.

✗
Setting environment variables with prefix TERRAFORM_.
Why it's wrong here
Correct prefix is TF_VAR_.
✗
Using the -vars flag to pass JSON string.
Why it's wrong here
No -vars flag; use -var or -var-file.
Common exam traps
Common exam trap: answer the scenario, not the keyword
HashiCorp often tests the exact environment variable prefix (`TF_VAR_` vs `TERRAFORM_`) and the existence of non-existent flags like `-vars`, expecting candidates to confuse them with similar-sounding options from other tools.
Detailed technical explanation
How to think about this question
Under the hood, Terraform loads variable definitions in a specific order of precedence: environment variables (`TF_VAR_*`) are overridden by `terraform.tfvars` (or any file passed with `-var-file`), which in turn are overridden by `-var` flags. In automated pipelines, using `-var-file` is common because it allows you to keep sensitive values in a secure store (e.g., HashiCorp Vault or CI/CD secrets) and write them to a temporary `.tfvars` file, ensuring variables are set before Terraform processes the configuration.
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 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.
