CGRC Compliance Maintenance Practice Question
Your organization uses Tenable.io for continuous monitoring of vulnerability status. You notice that several high-severity vulnerabilities remain 'open' despite being marked as 'patched' in your configuration management database. What is the most likely cause?
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
✓
The vulnerability scan was not performed after the patch was applied.
This discrepancy indicates a failure in the synchronization between the patch management process and the vulnerability management detection phase.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The Nessus scanner plugin needs an update to recognize the patch.
Why it's wrong here
While possible, the most likely cause is the verification step failing during the scan cycle.
- ✗
The scan policy is set to 'Discovery' instead of 'Audit'.
Why it's wrong here
Discovery scans still identify open vulnerabilities; the policy type is less relevant than the scan sequence.
- ✗
The scan agent was decommissioned prematurely.
Why it's wrong here
If the agent were decommissioned, you would see a 'missing agent' alert, not an 'open' vulnerability.
- ✓
The vulnerability scan was not performed after the patch was applied.
Why this is correct
Continuous monitoring requires validation scans to confirm patch effectiveness before updating the compliance status.
