CS0-003 Incident Response and Management Practice Question
This CS0-003 practice question tests your understanding of incident response and management. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. 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.
While supporting a hybrid workforce, a malware alert affects a single kiosk with no sensitive access. A second alert shows the same malware on a domain admin workstation. What should drive severity? During recovery, which decision is most defensible? which evidence should guide the decision?
Why wrong: Arrival order does not determine impact.
B
Business impact, privilege level, asset criticality, and spread potential
Severity should reflect impact and risk, not only malware family name. In recovery, responders need action that reduces risk while preserving the investigation record.
C
Alphabetical order of hostnames
Why wrong: Hostname order is irrelevant.
D
The analyst's preferred dashboard theme
Why wrong: UI preference is unrelated to incident severity.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Business impact, privilege level, asset criticality, and spread potential
Option B is correct because severity in incident response is determined by business impact, privilege level, asset criticality, and spread potential. The domain admin workstation has elevated privileges and access to critical systems, making the same malware far more dangerous than on a kiosk. This aligns with NIST SP 800-61 and common IR frameworks that prioritize containment based on risk, not chronology or naming.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the misconception that the first alert or a simple naming convention should drive severity, when in fact the correct approach is to evaluate the contextual risk factors like privilege and asset criticality.
Detailed technical explanation
How to think about this question
Under the hood, severity scoring often uses a weighted formula factoring in asset criticality (e.g., from a CMDB), user privilege level (e.g., domain admin vs. standard user), and lateral movement potential (e.g., Kerberos ticket abuse). In real-world scenarios, a kiosk alert might be a false positive or low-risk, while the same malware on a domain admin could lead to full domain compromise via pass-the-hash or Golden Ticket attacks, requiring immediate isolation and credential rotation.

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
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A SOC analyst notices unusual lateral movement in the network at 2 AM. The IR playbook dictates: identify and contain (isolate the affected machine), then eradicate (remove the malware), then recover (restore from backup), then document. Skipping containment before eradication risks the attacker regaining access. Questions like this test the sequence and rationale of incident response phases.
