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: risk registers document identified risks and their treatment.. 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 business unit accepts the risk of delaying a patch because downtime would breach a contractual deadline. What should be updated? 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
✓
The risk register with owner, justification, expiry date, and compensating controls
When a business unit formally accepts the risk of delaying a patch due to contractual constraints, the risk must be documented in the risk register. This entry should include the owner, justification, expiry date, and compensating controls to ensure the risk is tracked, reviewed, and eventually remediated. This aligns with the vulnerability management lifecycle, where accepted risks require formal documentation and periodic reassessment.
Key principle: Risk registers document identified risks and their treatment.
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 risk register with owner, justification, expiry date, and compensating controls
Why this is correct
Risk acceptance must be explicit, time-bound, owned, and controlled.
Related concept
Risk registers document identified risks and their treatment.
✗
The firewall vendor invoice
Why it's wrong here
Invoices do not record risk decisions.
✗
The incident containment playbook only
Why it's wrong here
This is a vulnerability-risk decision, not necessarily an incident.
✗
The phishing training completion list
Why it's wrong here
Training data does not document accepted patch risk.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between risk acceptance documentation (risk register) and operational documents (playbooks, invoices), tricking candidates into thinking any update related to the delay is sufficient, when only the risk register captures the formal acceptance process.
Detailed technical explanation
How to think about this question
In vulnerability management frameworks like NIST SP 800-40 or ISO 27005, risk acceptance requires a formal risk register entry with fields such as risk owner, justification, expiry date, and compensating controls. Compensating controls might include network segmentation, intrusion detection rules, or manual monitoring to reduce exploit likelihood until the patch is applied. The risk register is often integrated with GRC tools (e.g., RSA Archer, ServiceNow) to trigger review before the expiry date, ensuring the risk is not forgotten.
KKey Concepts to Remember
Risk registers document identified risks and their treatment.
Risk acceptance requires formal approval and documentation.
Compensating controls mitigate accepted risks.
Accepted risks should have an owner and an expiry date.
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
Risk registers document identified risks and their treatment.
Real-world example
How this comes up in practice
An employee at a financial services firm receives an email that appears to come from the IT helpdesk, asking them to reset their password via a link. The link leads to a convincing fake portal that harvests credentials. Security teams use phishing simulations and security-awareness training to reduce this attack vector. Questions like this test whether you can identify social engineering techniques and appropriate controls.
