Quick Answer
The answer is to run terraform plan in a pull request. This is a core Terraform CI/CD best practice because the plan command generates a detailed execution summary showing exactly what resources will be created, modified, or destroyed, without making any actual changes. By integrating this into a pull request workflow, team members can review the proposed infrastructure changes, catch potential errors, and discuss modifications before the plan is ever applied to production. On the HashiCorp Terraform Associate TF-003 exam, this concept tests your understanding of collaboration and safety in pipeline design—a common trap is choosing to run terraform apply directly in the PR, which would bypass review and risk unintended changes. Remember that plan is for preview and approval, while apply is for execution after review. A simple memory tip: "Plan in the PR, apply after the aye."

A DevOps engineer needs to integrate Terraform with a CI/CD pipeline. What is a common practice?
Run terraform plan in a pull request
Plan in PRs gives visibility into changes before apply.
Avoid using variables
Why wrong: Variables are essential for parameterizing configurations.
Use -auto-approve always
Why wrong: Auto-approve bypasses manual review, which is risky in CI/CD.
Store state in a local file
Why wrong: Local state is not suitable for team collaboration; remote state is recommended.

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.
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.
