- A
Apply a virtual patch via a web application firewall (WAF)
Why wrong: WAF is not relevant for container image vulnerability; no web traffic involved.
- B
Ignore the vulnerability because it is in a container image
Why wrong: Container images should still be patched; ignoring is not appropriate.
- C
Schedule the patch for the next maintenance window because of low EPSS and network controls
Low EPSS and existing network policies lower the risk, allowing normal scheduling.
- D
Immediately patch the vulnerability within 24 hours due to the high CVSS score
Why wrong: CVSS alone is not sufficient; EPSS and compensating controls reduce urgency.

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.
An analyst is reviewing a vulnerability scan report for a containerized application. The scan identifies a critical vulnerability in a base image used by multiple containers. The application is deployed in a Kubernetes cluster with network policies restricting ingress. The vulnerability has a CVSS v3.1 score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H). However, the EPSS score is 0.001 (0.1%). Which of the following should the analyst prioritize?
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
✓
Schedule the patch for the next maintenance window because of low EPSS and network controls
Despite high CVSS, the EPSS score indicates extremely low likelihood of exploitation in the wild. The business context and compensating controls (network policies) reduce risk. Therefore, remediation can be scheduled in normal patch cycle.
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.
- ✗
Apply a virtual patch via a web application firewall (WAF)
Why it's wrong here
WAF is not relevant for container image vulnerability; no web traffic involved.
- ✗
Ignore the vulnerability because it is in a container image
Why it's wrong here
Container images should still be patched; ignoring is not appropriate.
- ✓
Schedule the patch for the next maintenance window because of low EPSS and network controls
Why this is correct
Low EPSS and existing network policies lower the risk, allowing normal scheduling.

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.
