The answer is to issue a corrective action plan requiring the supplier to regain certification within three months, with monthly progress reviews. This is the most appropriate risk response because it directly addresses the supplier non-compliance risk by enforcing the contractual requirement for ISO 27001 certification while preserving a strategically important relationship. In the CRISC exam, this scenario tests your understanding of corrective action as a risk treatment option distinct from acceptance, termination, or transfer—common traps where candidates might overlook the contractual breach or overreact with termination. The key concept is that a corrective action plan remediates the root cause of non-compliance without abandoning the risk mitigation strategy already in place. For exam day, remember the memory tip: “Correct before you cut”—always prioritize a structured fix over drastic measures when the relationship and controls remain viable.
CRISC Risk Response and Mitigation Practice Question
This CRISC practice question tests your understanding of risk response and mitigation. 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 has adopted a risk mitigation strategy for its key suppliers by requiring them to maintain ISO 27001 certification. During an audit, the risk manager discovers that one critical supplier lost its certification six months ago but did not report it, as contractually required. The supplier still has adequate security controls in place, and the relationship is strategically important. The CEO wants to avoid contract termination. What is the MOST appropriate risk response?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Issue a corrective action plan requiring the supplier to regain certification within three months, with monthly progress reviews.
Option A is correct because it directly addresses the contractual breach with a remediation plan while keeping the supplier. Option B is wrong because acceptance disregards the contractual requirement. Option C is wrong because termination may be too severe and disrupt operations. Option D is wrong because transferring risk to the supplier's insurance does not restore certification.
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.
✓
Issue a corrective action plan requiring the supplier to regain certification within three months, with monthly progress reviews.
Why this is correct
This enforces the contract and restores the intended risk mitigation.
Related concept
Static NAT maps one inside address to one outside address.
✗
Transfer the risk to the supplier's cyber liability insurance policy.
Why it's wrong here
Insurance does not replace the need for certification or address the root cause.
✗
Accept the risk because the supplier still has effective controls, and update the risk register.
Why it's wrong here
Acceptance ignores the contractual breach and weakens the risk posture.
✗
Terminate the contract immediately and find an alternative supplier.
Why it's wrong here
Termination is disruptive and may not be necessary if the supplier can remediate.
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.
