- A
Medium CVSS score and high asset criticality
Why wrong: Asset criticality is important, but without EPSS or KEV evidence of exploitation, it may not be the highest priority.
- B
High EPSS score and presence in KEV catalog
Both factors indicate active exploitation and high likelihood of exploitation, making this the highest priority.
- C
High CVSS score and low EPSS score
Why wrong: High CVSS indicates severity, but low EPSS suggests low exploitation probability; KEV inclusion is not considered.
- D
Low CVSS score and presence in KEV catalog
Why wrong: While KEV inclusion is important, a low CVSS score may reduce priority, but this combination is still high, but not highest compared to both high EPSS and KEV.

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 team is using EPSS scores and CISA KEV catalog to prioritize vulnerabilities. Which combination of factors would indicate the HIGHEST priority for 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
✓
High EPSS score and presence in KEV catalog
CISA KEV catalog contains vulnerabilities known to be exploited in the wild, and a high EPSS score indicates a high probability of exploitation. Together, they indicate the highest priority.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Medium CVSS score and high asset criticality
Why it's wrong here
Asset criticality is important, but without EPSS or KEV evidence of exploitation, it may not be the highest priority.
- ✓
High EPSS score and presence in KEV catalog
Why this is correct
Both factors indicate active exploitation and high likelihood of exploitation, making this the highest priority.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
High CVSS score and low EPSS score
Why it's wrong here
High CVSS indicates severity, but low EPSS suggests low exploitation probability; KEV inclusion is not considered.
- ✗
Low CVSS score and presence in KEV catalog
Why it's wrong here
While KEV inclusion is important, a low CVSS score may reduce priority, but this combination is still high, but not highest compared to both high EPSS and KEV.
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.
