Quick Answer
The correct answer is identifying shares or systems touched by the compromised account, as this directly defines the blast radius in incident scoping for ransomware. By mapping every file share, mapped drive, and remote system the compromised user accessed, you determine exactly where encryption or lateral movement may have occurred, which is essential for containment and eradication. On the CompTIA CySA+ CS0-003 exam, this tests your ability to prioritize scoping over less actionable details—common traps include focusing on the ransom note contents or the encryption algorithm used, which do not limit spread. A strong memory tip is “follow the account, not the malware”: the user’s access footprint, not the ransomware strain, dictates the scope.
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.
What should be included in incident scoping for ransomware? (Choose three.)
Initial infected host and user context
The starting point helps identify root cause.
The brand of office chairs near the server room
Why wrong: Furniture brand is unrelated to ransomware scope.
Backup integrity and last known clean restore point
Recovery depends on clean backups.
Shares or systems touched by the compromised account
Access path shows spread.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Initial infected host and user context
Option A is correct because identifying the initial infected host and user context is critical for understanding the attack vector, containing the threat, and preventing further spread. In ransomware incidents, the first compromised system often reveals the entry point (e.g., phishing email, RDP brute force) and the user account used, which helps scope the blast radius and prioritize remediation.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Cisco often tests the ability to filter out irrelevant physical or administrative details (like office chairs) that distract from the core technical scoping steps required in incident response.
Detailed technical explanation
Backup integrity (Option C) is essential because ransomware often targets backup files; verifying the last known clean restore point ensures recoverability without paying ransom. Shares or systems touched by the compromised account (Option D) must be scoped to identify lateral movement, as ransomware often uses SMB or PsExec to propagate; tools like Sysmon Event ID 3 or Windows Security Event ID 5140 can track these connections.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
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.
