This CRISC practice question tests your understanding of it risk identification. 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.
A multinational corporation is expanding its cloud infrastructure to include a new SaaS application that stores sensitive customer data. The vendor claims compliance with SOC 2 Type II and ISO 27001. The risk manager must determine if the remaining residual risk after vendor controls is within the company's risk appetite. Which of the following is the MOST critical next step?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Conduct a data classification and legal review to identify applicable regulatory obligations.
Option B is correct because understanding the data classification and regulatory requirements determines if additional controls are needed beyond the vendor's certifications. Option A is wrong because certifications alone do not guarantee all risks are addressed. Option C is wrong because the vendor's own risk assessment may not consider the company's specific requirements. Option D is wrong because a pilot does not assess regulatory compliance.
Key principle: NAT direction and interface roles matter as much as the IP address mapping. Inside/outside designation controls which traffic is translated.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Request the vendor's latest risk assessment report.
Why it's wrong here
The vendor's risk assessment may not address the company's specific context.
✓
Conduct a data classification and legal review to identify applicable regulatory obligations.
Why this is correct
Data classification and legal review determine if additional controls are needed.
Related concept
Static NAT maps one inside address to one outside address.
✗
Perform a pilot deployment and monitor for security incidents.
Why it's wrong here
A pilot does not assess regulatory compliance before full deployment.
✗
Accept the vendor's certifications as sufficient evidence of control effectiveness.
Why it's wrong here
Certifications may not cover all specific regulatory requirements.
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 CRISC NAT questions on configuration and troubleshooting.

What is the correct answer to this question?
The correct answer is: Conduct a data classification and legal review to identify applicable regulatory obligations. — Option B is correct because understanding the data classification and regulatory requirements determines if additional controls are needed beyond the vendor's certifications. Option A is wrong because certifications alone do not guarantee all risks are addressed. Option C is wrong because the vendor's own risk assessment may not consider the company's specific requirements. Option D is wrong because a pilot does not assess regulatory compliance.
