Quick Answer
The most appropriate approach is to conduct a single privacy impact assessment that covers both GDPR and CCPA requirements. This is correct because both regulations share overlapping objectives regarding data subject rights and risk mitigation, so a unified PIA avoids redundant analysis while ensuring all mandatory elements—such as data mapping, lawful basis evaluation, and consumer opt-out mechanisms—are addressed in one streamlined process. On the CompTIA SecurityX CAS-004 exam, this concept tests your ability to apply privacy frameworks in a multinational context, often appearing in scenario-based questions where the trap is choosing separate PIAs for each regulation or delaying the assessment until after processing begins. A common memory tip is to think of the PIA as a single “privacy umbrella” that covers both GDPR’s Data Protection Impact Assessment (DPIA) and CCPA’s risk assessment requirements, focusing on efficiency without sacrificing compliance.
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 implementing a privacy program that must comply with both GDPR and CCPA. Which approach to privacy impact assessments (PIAs) is most appropriate?
Perform separate PIAs for GDPR and CCPA requirements
Why wrong: Duplicative and inefficient
Skip PIAs for existing processing activities
Why wrong: PIAs are required for high-risk processing
Conduct a single PIA that covers both regulations' requirements
Comprehensive and efficient
Only perform PIAs when processing high-risk data
Why wrong: CCPA does not mandate PIAs for all but high-risk
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Conduct a single PIA that covers both regulations' requirements
Option B is correct because conducting a single PIA that addresses both regulations is efficient. Option A is wrong because separate PIAs are redundant. Option C is wrong because PIAs should be conducted before processing. Option D is wrong because only high-risk processing is not sufficient for all processing.
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
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
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.
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
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
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.
