- A
Remediate vulnerabilities with high CVSS scores only if they are internet-facing.
Why wrong: Internal assets can also be critical and should not be ignored.
- B
Prioritize based on EPSS scores and KEV status, but also consider business context.
EPSS and KEV provide real-world exploitation context, and business context ensures critical assets are protected.
- C
Remediate only vulnerabilities found in the KEV catalog.
Why wrong: Other vulnerabilities may still pose risk to critical assets.
- D
Remediate all vulnerabilities with CVSS scores above 9.0 immediately.
Why wrong: While high severity is important, ignoring EPSS and KEV may lead to misallocating resources.

CS0-003 Vulnerability Management Practice Question
This CS0-003 practice question tests your understanding of vulnerability management. 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 security analyst is reviewing the results of a vulnerability scan and notices that several vulnerabilities have high CVSS scores but low EPSS scores. The analyst also cross-references the CISA Known Exploited Vulnerabilities (KEV) catalog and finds that none of these vulnerabilities are listed. Which approach should the analyst take when prioritizing remediation?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Prioritize based on EPSS scores and KEV status, but also consider business context.
EPSS predicts the likelihood of exploitation, and KEV lists vulnerabilities known to be exploited in the wild. High CVSS but low EPSS and not in KEV suggests the vulnerability may be severe but unlikely to be exploited currently. However, business context such as asset criticality and exposure should be considered; if the asset is critical and exposed, remediation should still be prioritized despite low exploitation likelihood.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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 security team runs a vulnerability scan on a web application and discovers an unpatched SQL injection flaw. The team prioritises remediation by CVSS score — critical flaws are patched within 24 hours, high within 7 days. Questions like this test whether you understand vulnerability management processes, scanning tools, and remediation prioritisation.
