20+ practice questions focused on Incident Response and Management — one of the most tested topics on the CompTIA CySA+ CS0-003 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Incident Response and Management PracticeDuring the detection and analysis phase of the NIST SP 800-61 incident response lifecycle, an analyst identifies suspicious network traffic from an internal host to a known malicious IP address. Which step should the analyst perform next to validate the alert?
Explanation: Option B is correct because during the detection and analysis phase, the primary goal is to validate the alert by correlating it with additional data sources (e.g., firewall logs, DNS logs, endpoint detection and response (EDR) telemetry) to confirm whether the traffic is truly malicious or a false positive. Simply searching external threat intelligence (Option A) provides context but does not confirm activity on the host; escalation (Option C) and containment (Option D) are premature without validated evidence.
An organization's security team receives an alert about a potential ransomware infection on a critical server. The severity classification is 'high' because the server supports a production database. According to the incident response plan, which containment action should be taken first to minimize data loss?
Explanation: Isolating the network connection prevents lateral movement and further encryption while preserving evidence for forensic analysis.
A forensic analyst is investigating a suspected data breach involving a compromised workstation. The analyst wants to collect volatile data in accordance with the order of volatility. Which sequence of data collection is correct?
Explanation: The order of volatility starts with the most volatile data (CPU registers/cache) and proceeds to the least volatile (archived media).
After containing a malware outbreak, the incident response team performs static malware analysis on a suspicious executable. Which of the following artifacts would be most helpful in creating a YARA rule to detect variants of the malware?
Explanation: Import table analysis reveals API calls and DLLs used by the malware, which are often consistent across variants and useful for detection.
During dynamic malware analysis in a sandbox, an analyst observes that the malware attempts to connect to a remote IP address on port 443, modifies the Windows registry under HKCU\Software\Microsoft\Windows\CurrentVersion\Run, and drops a DLL in the system32 folder. Which type of IOC is most indicative of persistence?
Explanation: The registry modification to HKCU\Software\Microsoft\Windows\CurrentVersion\Run is the most indicative of persistence because this specific key is designed to automatically launch programs when a user logs in. By adding a value here, the malware ensures it executes on every system startup, which is the definition of persistence. In contrast, network connections and file drops are common during execution but do not inherently guarantee re-execution after a reboot.

Start with 10 questions to gauge your current understanding of Incident Response and Management. This tells you whether you need a concept refresher or just practice.
2. Review every explanation
For each question — right or wrong — read the full explanation. Understanding why an answer is correct is more valuable than knowing the answer itself.
3. Focus on exam traps
Incident Response and Management questions on the CS0-003 frequently use trap wording. Look for subtle differences in answers that test your precision, not just general knowledge.
4. Reach 80% consistently
Do repeated sessions until you score 80%+ three times in a row. Then move to mixed-mode practice to test cross-topic recall under realistic conditions.
The exact number varies per candidate. Incident Response and Management is tested as part of the CompTIA CySA+ CS0-003 blueprint. Practicing with targeted Incident Response and Management questions ensures you can handle any format or difficulty that appears.
