This TF-003 practice question tests your understanding of understand iac concepts. 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 uses Terraform to deploy virtual machines. They want to ensure that the same exact operating system and software versions are used every time. Which practice supports this?
Manually installing software
Why wrong: Manual steps are error-prone and not repeatable.
Using a golden image and referencing it in the configuration
A golden image provides a consistent base.
Using inline userdata scripts
Why wrong: Userdata scripts can vary and are not as reliable as a pre-built image.
Running configuration management after provisioning
Why wrong: This can cause drift if not perfectly managed.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Using a golden image and referencing it in the configuration
Option B is correct because using a golden image—a pre-configured virtual machine template containing the exact operating system and software versions—ensures consistency across deployments. Terraform can reference this image via the `source_image` or `image_id` argument in a resource like `azurerm_virtual_machine` or `aws_instance`, guaranteeing that every provisioned VM starts from the same immutable baseline.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

Common exam traps
HashiCorp often tests the misconception that userdata scripts or configuration management tools can guarantee identical software versions, but the trap is that these methods depend on external sources (repositories, scripts) that can change over time, whereas a golden image captures a fixed, immutable state at build time.
Detailed technical explanation
A golden image is typically created using tools like Packer, which automates the building of a machine image with a specific OS, patches, and software. Terraform then references the image ID (e.g., an AMI in AWS or a managed image in Azure) in the resource definition. This approach leverages immutability—if a change is needed, a new golden image is built and deployed, avoiding in-place updates that can cause drift. Under the hood, Terraform uses the image ID as a unique identifier, and any change to the image triggers a replacement of the resource.
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.
