The answer is that the most significant weakness is the remediation may not eliminate the segregation of duties issue. This is because an automated code review tool, while useful, can still be operated by the same developer who wrote the code, thereby failing to enforce the fundamental control of separating the coding and review functions. On the Certified Information Systems Auditor CISA exam, this scenario tests your ability to distinguish between a technical fix and a process control failure; a common trap is to focus on the tool’s capabilities rather than the underlying lack of independent oversight. Remember the memory tip: “Tool without a different hand is just a rubber stamp”—the remediation must ensure a different person performs the review, not just a different method.
CISA Governance and Management of IT Practice Question
This CISA practice question tests your understanding of governance and management of it. 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.
Exhibit
Refer to the exhibit.
The following is an excerpt from an IT control self-assessment report:
Control: Segregation of duties in system development
Finding: In 3 out of 10 projects, the same developer who wrote code also performed code review.
Risk: High
Planned Remediation: Implement automated code review tool by Q3.
What is the MOST significant weakness in the planned remediation?

The following is an excerpt from an IT control self-assessment report:
Control: Segregation of duties in system development

Risk: High
Planned Remediation: Implement automated code review tool by Q3.
A
The remediation only addresses a subset of projects.
Why wrong: The tool could be applied to all projects; the plan does not specify limiting scope.
B
The remediation may not eliminate the segregation of duties issue.
An automated tool does not prevent the same developer from performing both coding and review if they run the tool.
C
The remediation relies on technology rather than process.
Why wrong: While relevant, the primary issue is that the tool does not enforce segregation.
D
The remediation does not include a compensating control.
Why wrong: Lack of compensating control is a concern but not the most significant weakness.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The remediation may not eliminate the segregation of duties issue.
Option C is correct because an automated code review tool may still be run by the same developer, not ensuring segregation of duties. The remediation does not address the root cause of the same person performing both tasks. Option A (only addresses subset) is not the most significant; the tool could be applied to all projects. Option B (technology vs. process) is valid but secondary. Option D (no compensating control) is related but not as direct.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.

Common exam traps
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Detailed technical explanation
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
Static NAT maps one inside address to one outside address.
PAT allows many inside hosts to share one public address using ports.
Inside local and inside global describe the private and translated addresses.
NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
→Identify inside and outside interfaces first.
→Check whether the scenario needs static NAT, dynamic NAT or PAT.
→Do not confuse NAT matching ACLs with normal packet-filtering intent.
Key takeaway
NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
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.
What to study next
Got this wrong? Here's your next step.
Review the four NAT address types (inside local, inside global, outside local, outside global), PAT port overload, and static vs dynamic NAT use cases. Then practise related CISA NAT questions on configuration and troubleshooting.
