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 vulnerability management team uses OpenVAS to scan a network of 500 hosts weekly. The scans are causing network congestion and generating false positives. Which of the following would BEST reduce the impact while maintaining effective vulnerability detection?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "best"
Why it matters: Signals that multiple options may be partially correct. Choose the option that most directly solves the exact problem described, not the one that sounds most complete.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Schedule scans during off-peak hours and limit concurrent scans.
Scheduling scans during off-peak hours and limiting concurrent scans directly reduces network congestion by shifting traffic to low-utilization periods and capping the number of simultaneous connections. This approach maintains the weekly scan frequency and full vulnerability coverage, unlike other options that degrade detection effectiveness.
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.
✗
Disable the vulnerable host discovery phase.
Why it's wrong here
Disabling host discovery may miss new or changed hosts.
✗
Increase the scan interval to monthly.
Why it's wrong here
Monthly scanning reduces frequency but may miss vulnerabilities.
✗
Use credential-based scanning to reduce false positives.
Why it's wrong here
This reduces false positives but does not address network congestion.
✓
Schedule scans during off-peak hours and limit concurrent scans.
Why this is correct
This reduces network impact while maintaining scan effectiveness.
Clue confirmation
The clue word "best" in the question point toward this answer.

Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the misconception that reducing false positives (credential-based scanning) solves network congestion, but the question specifically asks about reducing impact from congestion, not improving accuracy.
Detailed technical explanation
How to think about this question
OpenVAS uses a two-phase approach: host discovery (e.g., via ICMP ping or TCP SYN scans) and vulnerability scanning. Limiting concurrent scans throttles the number of parallel NVT (Network Vulnerability Test) executions, which reduces burst traffic and prevents switch/router buffer exhaustion. Off-peak scheduling aligns with typical IT maintenance windows, ensuring minimal business disruption while preserving the weekly scan cycle.
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 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.
