The answer is storing IaC templates in a version control system like Git, which is a core best practice for infrastructure as code deployment. This is correct because version control enables change tracking, rollback, collaboration, and auditability, aligning with GitOps principles where the repository serves as the single source of truth for infrastructure state. On the CompTIA Cloud+ CV0-004 exam, this concept tests your understanding of how to maintain consistency and reliability in cloud deployments, often appearing as a distractor against manual configuration or single-file approaches. A common trap is assuming that simply writing IaC scripts is sufficient without versioning them, or confusing immutable infrastructure patterns with the version control requirement itself. Remember the memory tip: “Git it right” — if your IaC isn’t in version control, you’re not following best practices.
CV0-004 Deployment Practice Question
This CV0-004 practice question tests your understanding of deployment. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 THREE of the following are best practices when deploying a cloud application using Infrastructure as Code (IaC)? (Choose three.)
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Store IaC templates in a version control system.
Storing IaC templates in a version control system (e.g., Git) is a best practice because it enables change tracking, rollback, collaboration, and auditability. This aligns with GitOps principles, where the version control repository serves as the single source of truth for infrastructure state, ensuring all changes are reviewed and recorded.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

✓
Break down complex deployments into reusable modules.
Why this is correct
Modularization improves maintainability and reuse.

✗
Embed credentials directly in the IaC templates.
Why it's wrong here
Credentials should be stored in a secure secrets manager.
✗
Manually modify resources after deployment to tune performance.
Why it's wrong here
Manual modifications cause configuration drift.
✓
Use immutable infrastructure patterns where possible.
Why this is correct
Immutable infrastructure prevents drift and simplifies rollback.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between mutable and immutable infrastructure, and the trap here is that candidates may think manual tuning (Option D) is acceptable for performance optimization, but it violates the core IaC principle of idempotent, automated deployments.
Detailed technical explanation
How to think about this question
Immutable infrastructure patterns (Option E) involve replacing entire instances rather than patching them, which eliminates configuration drift and ensures consistency across environments. Under the hood, this leverages auto-scaling groups or orchestration tools (e.g., Kubernetes Deployments) to perform rolling updates, where new instances are created from a golden image and old ones are terminated, reducing the risk of snowflake servers.

TExam Day Tips
→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 small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
