- A
All .tf files in subdirectories are automatically loaded.
Why wrong: Terraform only loads .tf files from the root directory unless using -chdir or specifying paths.
- B
A file named terraform.tfvars is automatically processed.
Terraform automatically loads terraform.tfvars if present in the root directory.
- C
The backend configuration must be defined in the same file as the provider configuration.
Why wrong: Backend configuration can be defined in a separate file and is merged during initialization.
- D
The -var-file flag accepts a comma-separated list of variable files.
Why wrong: The -var-file flag only accepts a single file path; use multiple -var-file flags for multiple files.
- E
Variable definitions files can have .tfvars.json extension.
Terraform supports both .tfvars and .tfvars.json variable definition files.
Quick Answer
The correct answer is that variable definitions files can have a .tfvars.json extension, and Terraform automatically loads terraform.tfvars without requiring any flags. This is because Terraform’s configuration file loading behavior is designed to auto-load any file named exactly terraform.tfvars or terraform.tfvars.json, as well as any file ending in .auto.tfvars or .auto.tfvars.json, from the current working directory. On the HashiCorp Terraform Associate TF-003 exam, this concept tests your understanding of implicit versus explicit variable file loading, and a common trap is assuming Terraform loads .tf files recursively—it does not, as it only processes the root directory by default. Another frequent mistake is thinking the -var-file flag accepts comma-separated lists, but you must repeat the flag for each file. To remember this, think of the “auto” in .auto.tfvars as “automatic loading,” and note that JSON support is a direct extension of the standard .tfvars format.
TF-003 Read, generate and modify configuration Practice Question
This TF-003 practice question tests your understanding of read, generate and modify configuration. 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.
Which TWO statements about Terraform configuration files are correct? (Choose two.)
Answer choices
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 file named terraform.tfvars is automatically processed.
Option B and C are correct because Terraform automatically loads terraform.tfvars and also supports .tfvars.json extension. Option A is incorrect because Terraform does not load .tf files recursively by default. Option D is incorrect because the -var-file flag does not accept comma-separated lists; you must use multiple flags. Option E is incorrect because backend configuration does not have to be in the same file as provider configuration.
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
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.
Detailed technical explanation
How to think about this question
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.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

Variation 1. Which TWO statements about Terraform's handling of input variables are true?
medium- A.All variables must be assigned a value before running terraform plan.
- B.Variable values cannot be overridden using environment variables.
- ✓ C.The terraform.tfvars file is automatically loaded by Terraform.
- D.Default values for variables can only be set using a .tfvars file.
- ✓ E.Variables can be declared in a .tf file using the 'variable' block.
Why C: Option A is correct because variables are declared using the 'variable' block in .tf files. Option C is correct because Terraform automatically loads terraform.tfvars. Option B is incorrect because variables can have defaults and are not required to be assigned before plan. Option D is incorrect because environment variables with TF_VAR_ prefix can override variable values. Option E is incorrect because default values are set in the variable block, not in .tfvars files.
