Quick Answer
The answer is tracking changes made by developers and the ability to rollback or revert code. These two benefits are foundational to version control systems like Git or SVN, as they provide a complete audit trail of every modification and allow teams to restore previous stable states of the codebase. This rollback capability is critical for recovering from bugs or regressions, preserving the full history of changes and enabling safe experimentation without risk of permanent damage. On the Certified Information Systems Auditor CISA exam, this concept tests your understanding of change management and configuration management controls, often appearing in questions about software development lifecycle governance. A common trap is confusing version control with backup systems—backups only store snapshots, while version control tracks granular changes and supports rollback to any specific commit. Remember the mnemonic “Revert and Record” to recall that rollback and change tracking are the two core benefits.
This CISA practice question tests your understanding of information systems acquisition, development and implementation. 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 TWO of the following are benefits of using a version control system in software development?
Generate test cases
Why wrong: Not a VCS feature.
Eliminate all bugs
Why wrong: Impossible.
Automate deployment
Why wrong: CI/CD tool.
Rollback to previous versions
Core feature.
Track changes made by developers
Core feature.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Rollback to previous versions
Option D is correct because version control systems (e.g., Git, SVN) allow developers to revert code to a previous commit or tag, enabling recovery from bugs or regressions. This rollback capability is a core feature that preserves the history of the codebase and supports safe experimentation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
The trap here is that candidates confuse version control with CI/CD or testing tools, mistakenly thinking VCS can automate deployment or generate test cases, when its primary purpose is change tracking and history management.
Detailed technical explanation
Version control systems like Git use a directed acyclic graph (DAG) of commits, each identified by a SHA-1 hash, to track every change. The `git revert` command creates a new commit that undoes a previous commit, while `git reset` moves the branch pointer to an earlier commit, effectively rolling back the working directory. In a real-world scenario, a team might use `git bisect` to binary-search through commits to identify the exact change that introduced a production bug, then rollback to the last known good state.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
