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. A key principle to apply: authenticated scans provide deeper visibility into host configurations.. 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 scan of Windows servers reports few findings, but the scanner used no credentials. The security manager suspects missing patch data. What should be changed? For validation, Which action should be taken before closing or downgrading the finding?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Run authenticated scans using least-privilege scanner credentials
Unauthenticated scans rely on network-level probes and can only detect vulnerabilities visible without credentials, such as open ports or banner information. Patch status for Windows servers requires authenticated access to query the registry, WMI, or the Windows Update API. Using least-privilege scanner credentials enables the scanner to perform authenticated checks, revealing missing patches that were previously hidden.
Key principle: Authenticated scans provide deeper visibility into host configurations.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Run authenticated scans using least-privilege scanner credentials
Why this is correct
Authenticated scanning gives the scanner access to installed software and patch state, improving accuracy.
Related concept
Authenticated scans provide deeper visibility into host configurations.
✗
Trust the unauthenticated result as complete
Why it's wrong here
Unauthenticated scans commonly miss local configuration and patch data.
✗
Disable host firewalls permanently
Why it's wrong here
This is unnecessary and creates risk.
✗
Increase only the port range
Why it's wrong here
More ports will not reveal installed patch levels reliably.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that unauthenticated scans are sufficient for vulnerability management, when in fact they miss the majority of patch-related findings that require credentialed access.
Detailed technical explanation
How to think about this question
Authenticated scanning on Windows typically uses WMI (Windows Management Instrumentation) or WinRM (Windows Remote Management) to enumerate installed patches via the Microsoft.Update.Session COM object or the Win32_QuickFixEngineering WMI class. The scanner must have local administrator privileges on the target to read the patch registry keys under HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall. In real-world scenarios, a common pitfall is using domain admin credentials that are blocked by User Account Control (UAC) remote restrictions, requiring the scanner account to be added to the local Administrators group or to have the 'Remote Registry' service running.
KKey Concepts to Remember
Authenticated scans provide deeper visibility into host configurations.
Least privilege ensures scanner credentials minimize risk.
Unauthenticated scans often miss internal patch and software data.
→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
Authenticated scans provide deeper visibility into host configurations.
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.
