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
✓
Use an Infrastructure as Code (IaC) template to define security group rules.
The best practice to prevent missing security group rules is to use Infrastructure as Code (IaC) templates (Option B). IaC allows you to define security group rules declaratively, ensuring consistency and enabling version control and automated validation before deployment. Manual checklists (Option A) are error-prone and rely on human memory. Cloning a security group (Option C) does not guarantee the cloned group has the correct rules and does not address the root cause of inconsistent configurations. Allowing all traffic by default (Option D) is insecure and violates the principle of least privilege. By using IaC, you enforce security configurations programmatically, reducing the risk of misconfigurations.
