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 acceptance must be formally documented in a risk register.. 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 control selection, Which control best addresses the stated weakness without hiding risk?
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
✓
The risk register with owner, justification, expiry date, and compensating controls
Option B is correct because when a business unit accepts the risk of delaying a patch, the risk register must be updated to formally document the risk acceptance. This update should include the risk owner, the business justification for the delay, an expiry date for the exception, and any compensating controls (e.g., network segmentation, enhanced monitoring) that reduce the risk during the gap. This ensures the risk is tracked, reviewed, and eventually remediated, aligning with vulnerability management best practices.
Key principle: Risk acceptance must be formally documented in a risk register.
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 phishing training completion list
Why it's wrong here
Training data does not document accepted patch risk.
✓
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.
Clue confirmation
The clue word "best" in the question point toward this answer.
Related concept
Risk acceptance must be formally documented in a risk register.
✗
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.
Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between operational activities (e.g., training, billing) and formal risk management documentation; the trap here is that candidates may confuse updating a training list or invoice with the required risk register update, failing to recognize that risk acceptance must be formally recorded with ownership and compensating controls.
Detailed technical explanation
How to think about this question
In vulnerability management, a risk register is a formal artifact that records each identified risk, its likelihood, impact, owner, and treatment decision (e.g., accept, mitigate, transfer). When a patch is delayed, compensating controls such as host-based firewalls, intrusion detection system (IDS) rules, or virtual patching via a web application firewall (WAF) should be documented to reduce the window of exposure. The expiry date ensures the exception is temporary and triggers a review, preventing indefinite risk acceptance that could lead to compliance violations (e.g., PCI DSS Requirement 6.2).
KKey Concepts to Remember
Risk acceptance must be formally documented in a risk register.
Accepted risks require an owner, justification, and expiry date.
Compensating controls should be implemented for accepted risks.
The risk register tracks all identified risks and their treatment plans.
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 acceptance must be formally documented in a risk register.
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.
