CRISC Risk Response and Mitigation Practice Question
This CRISC practice question tests your understanding of risk response and mitigation. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 security team identifies a critical vulnerability in a web application that cannot be patched immediately. They deploy a web application firewall (WAF) to block exploitation attempts. This is an example of:
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "immediately / without restart"
Why it matters: Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Risk Mitigation
Option A is correct because deploying a WAF reduces the likelihood of exploitation, which is a risk mitigation strategy.
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.
✗
Risk Transfer
Why it's wrong here
Transfer involves shifting risk to another party, e.g., via insurance or outsourcing.
✓
Risk Mitigation
Why this is correct
Deploying a WAF reduces risk, so it is mitigation.
Clue confirmation
The clue word "immediately / without restart" in the question point toward this answer.
Related concept
Static NAT maps one inside address to one outside address.
✗
Risk Avoidance
Why it's wrong here
Avoidance would mean not using the application or eliminating the vulnerability, not just blocking exploitation.
✗
Risk Acceptance
Why it's wrong here
Acceptance means acknowledging the risk without taking action, which is not the case here.
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.
Risk Response and Mitigation — This question tests Risk Response and Mitigation — Static NAT maps one inside address to one outside address..
What is the correct answer to this question?
The correct answer is: Risk Mitigation — Option A is correct because deploying a WAF reduces the likelihood of exploitation, which is a risk mitigation strategy.
What should I do if I get this CRISC question wrong?
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.
Are there clue words in this question I should notice?
Yes — watch for: "immediately / without restart". Time or reboot constraint — the correct answer must take effect right away without requiring a reboot or reload.
What is the key concept behind this question?
Static NAT maps one inside address to one outside address.
