- A
Implement data mapping to track personal data across systems and jurisdictions.
Data mapping is a foundational governance activity required by both GDPR and CCPA.
- B
Establish data classification policies to categorize information based on sensitivity.
Data classification is a key governance control enabling appropriate handling under both regulations.
- C
Deploy data loss prevention (DLP) technology to monitor data exfiltration.
Why wrong: DLP is a technical control, not a governance control.
- D
Define a data retention schedule that automatically deletes data after a set period.
Why wrong: Retention is important but not the most critical governance control for both regulations.
- E
Integrate a security information and event management (SIEM) system for log analysis.
Why wrong: SIEM is a security monitoring tool, not a governance control.
CAS-004 Governance, Risk and Compliance Practice Question
This CAS-004 practice question tests your understanding of governance, risk and compliance. Compare every option against the stated constraints before choosing — the best answer satisfies all requirements, not just the most obvious one. 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.
A multinational corporation is subject to GDPR and the California Consumer Privacy Act (CCPA). A security architect is designing a data governance solution to meet both regulations. Which TWO controls are most appropriate?
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
Implement data mapping to track personal data across systems and jurisdictions.
Options A and D are correct. GDPR and CCPA both require data mapping (A) to understand data flows, and data classification (D) to apply appropriate controls. Option B (retention schedule) is important but not the most critical for both regulations; retention is more GDPR-specific. Option C (DLP) is a technical control that supports compliance but is not a governance control. Option E (SIEM) is a security monitoring tool, not a governance control.
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 CAS-004 NAT questions on configuration and troubleshooting.
