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 use credentials to log into target systems.. 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 business prioritization, Which recommendation gives the best risk-based order of work?
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
✓
Run authenticated scans using least-privilege scanner credentials
Without credentials, a vulnerability scanner can only perform unauthenticated checks, which miss many Windows patch vulnerabilities that require registry or file-level access. Running authenticated scans with least-privilege credentials allows the scanner to query the Windows Update Agent API and check installed KBs, providing accurate patch data. This directly addresses the security manager's concern about missing patch data.
Key principle: Authenticated scans use credentials to log into target systems.
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 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.
✓
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.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Authenticated scans use credentials to log into target systems.
✗
Trust the unauthenticated result as complete
Why it's wrong here
Unauthenticated scans commonly miss local configuration and patch data.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that increasing scan scope (ports or targets) or disabling security controls will improve vulnerability detection, when the real fix is enabling authenticated access to gather patch-level data.
Detailed technical explanation
How to think about this question
Authenticated scans use protocols like WMI (Windows Management Instrumentation) or WinRM to remotely query the Windows Registry (HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall) and the Windows Update Agent API (wuapi.dll) for installed KBs. The scanner must have local administrator privileges on the target to read these registry keys and execute WMI queries; least-privilege credentials can be configured via a dedicated domain account with the 'Log on as a batch job' right and membership in the local 'Remote Management Users' group.
KKey Concepts to Remember
Authenticated scans use credentials to log into target systems.
Authenticated scans provide deep insight into system configuration and patch levels.
Least-privilege credentials should always be used for scanner accounts.
Unauthenticated scans often miss internal vulnerabilities and patch data.
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
Authenticated scans use credentials to log into target systems.
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.
