CS0-003 Vulnerability Management Practice Question
A security analyst is configuring a vulnerability scanner to perform a scan of a network segment. The analyst wants to minimize the risk of disrupting critical production systems during the scan. Which of the following scanner settings should the analyst adjust?
⚠ Common exam trap
The trap here is assuming that scheduling the scan during off-peak hours is sufficient to prevent disruption, when the scan's intensity is the primary factor affecting system load.
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
✓
Scan intensity
Scan intensity determines how aggressively the scanner probes systems, including the rate of connections and the types of checks performed. Lowering intensity reduces the chance of causing performance issues or crashes on production systems. While scheduling and credentialed scanning have their place, adjusting intensity is the most direct way to minimize disruption. Plugin updates are unrelated to scan impact.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Scan schedule
Why it's wrong here
Scheduling the scan during off-peak hours can reduce the impact on users, but it does not reduce the technical risk of disruption if the scan itself is aggressive. The analyst should adjust scan intensity to control how the scan interacts with systems. Scheduling is complementary but not the main setting to prevent disruption during the scan.
- ✓
Scan intensity
Why this is correct
Scan intensity controls the aggressiveness of the scan, including the number of concurrent connections and payloads sent. Lowering intensity reduces the risk of overwhelming production systems, which could cause outages. The analyst should set a lower intensity to avoid disruption while still identifying vulnerabilities. This setting directly addresses the need to balance thoroughness with system stability.
- ✗
Credentialed scanning
Why it's wrong here
Credentialed scanning provides deeper visibility but does not inherently reduce disruption. In fact, it may perform more checks that could impact system performance. The analyst should consider credentialed scanning for accuracy, but it is not the primary setting to minimize disruption. Scan intensity is more directly related to the load placed on systems during scanning.
- ✗
Plugin updates
Why it's wrong here
Updating plugins ensures the scanner has the latest vulnerability checks, improving accuracy. However, it does not affect the scan's impact on production systems. The analyst should update plugins regularly, but to minimize disruption, scan intensity is the relevant setting. Plugin updates do not control network load or system stress.

Risk
Risk is the possibility that an event or action will negatively affect an organization's ability to achieve its goals, often measured in terms of likelihood and impact.
Key term
Vulnerability scanner
A vulnerability scanner is an automated tool that identifies security weaknesses in systems, networks, and applications by comparing their configurations and software versions against known vulnerability databases.
