CAS-004 Benefit of IaC for security Practice Question
Which of the following is the primary benefit of using infrastructure as code (IaC) for automating security configurations?
⚠ Common exam trap
It's easy for candidates to think IaC eliminates the need for security testing (Option A) because automation implies perfection, but in reality, IaC code itself must be tested for security flaws, just like application code.

Correct answer & explanation
✓
It ensures consistent and repeatable security configurations
Infrastructure as code (IaC) enables security configurations to be defined in declarative or procedural scripts (e.g., Terraform, AWS CloudFormation, Ansible). This ensures that every deployment applies the exact same security settings (e.g., firewall rules, IAM policies, encryption at rest) without drift, making configurations consistent and repeatable across environments. The primary benefit is eliminating manual, error-prone processes that lead to configuration inconsistencies.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
It eliminates the need for security testing
Why it's wrong here
IaC does not eliminate testing; it automates deployment.
- ✗
It allows unapproved changes to be deployed faster
Why it's wrong here
Unapproved changes are a risk, not a benefit.
- ✗
It increases manual oversight of security settings
Why it's wrong here
IaC reduces manual oversight.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The CAS-005 exam frequently reuses these exact scenarios with slightly different constraints.
