CRISC IT Risk Assessment Practice Question
This CRISC practice question tests your understanding of it risk assessment. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
During an IT risk assessment, the risk owner identifies a high inherent risk for a legacy system. After implementing a firewall and intrusion detection system, the residual risk is calculated. Which of the following best describes residual risk?

Correct answer & explanation
✓
The risk level after considering control effectiveness
Residual risk is the level of risk that remains after controls have been implemented and their effectiveness has been factored in. In this scenario, the firewall and intrusion detection system are controls that reduce the inherent risk, but some risk (e.g., from zero-day exploits or misconfigurations) will persist, which is the residual risk.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

- ✗
The risk level before any controls are implemented
Why it's wrong here
That is inherent risk.
- ✓
The risk level after considering control effectiveness
Why this is correct
Residual risk is inherent risk adjusted for control effectiveness.
Clue confirmation

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is confusing residual risk with inherent risk (Option A) or with risk response strategies like transfer (Option C) or acceptance (Option D), rather than recognizing it as the risk remaining after control implementation.
Detailed technical explanation
How to think about this question
Residual risk is calculated by assessing the likelihood and impact of a threat exploiting a vulnerability after controls are in place, often using a formula like Residual Risk = Inherent Risk - Control Effectiveness. In practice, controls like a firewall (e.g., stateful inspection with ACLs) and an IDS (e.g., signature-based detection) reduce but never eliminate risk; for example, a firewall cannot block all application-layer attacks, and an IDS may have false negatives. The CRISC exam emphasizes that residual risk must be formally documented and accepted by the risk owner.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CRISC exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
