- A
Low risk; no action needed because internal IP disclosure is not a vulnerability.
Why wrong: While low risk, it is still a vulnerability that should be remediated per policy.
- B
Critical risk because the server is public-facing; immediate patching is required.
Why wrong: Critical risk would require high impact; this is low impact.
- C
Medium risk; schedule a configuration change to remove the header during the next maintenance window.
The risk is medium, and the fix is a configuration change that can be scheduled.
- D
High risk due to public exposure; apply an emergency patch to hide the header.
Why wrong: The impact is low, so emergency patch is not warranted.

CS0-003 Vulnerability Management Practice Question
This CS0-003 practice question tests your understanding of vulnerability management. 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 analyst is using Nessus to scan a network. The scan completes and reports a vulnerability with a CVSS v3.1 base score of 5.3 and vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N. The vulnerability is a low-information disclosure issue that reveals the server's internal IP address in HTTP headers. The asset is a public-facing web server. Which of the following best describes the risk level and appropriate response?

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
✓
Medium risk; schedule a configuration change to remove the header during the next maintenance window.
The CVSS score is 5.3 (Medium) with low impact on confidentiality and no impact on integrity or availability. Although it is a public-facing server, the risk is low because the information disclosed is minimal (internal IP), which may already be known or easily guessable. The appropriate response is to schedule remediation during normal maintenance, not an emergency.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis

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.
