20+ practice questions focused on Incident Response and Management — one of the most tested topics on the CompTIA CySA+ CS0-004 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Incident Response and Management PracticeAn analyst receives an alert about a user account that has been locked out multiple times within an hour. The account belongs to a system administrator. Which incident category does this scenario most likely fall under?
Explanation: A system administrator account being locked out multiple times in an hour suggests a deliberate attempt to guess or brute-force the credentials, or the admin themselves may be performing unauthorized actions that trigger lockout policies. This aligns with an insider threat because the account has elevated privileges and the anomalous lockout pattern indicates either a compromised credential or malicious insider activity, not an external network-based attack.
Which of the following is the MOST volatile data according to the order of volatility?
Explanation: CPU registers and cache are the most volatile because they store data only while the system is powered on and actively executing instructions. Unlike RAM, which retains data for a short time after power loss, registers and cache lose their contents almost instantly when power is removed, making them the highest priority in the order of volatility (OOV) for forensic acquisition.
A company has experienced a ransomware attack that encrypted critical servers. The incident response team is in the containment, eradication, and recovery phase. Which THREE actions are part of long-term containment? (Choose three.)
Explanation: Long-term containment focuses on hardening the environment and preventing re-infection while recovery proceeds, so A (Apply security patches to vulnerable systems) is correct because remediating the exploited vulnerability removes the initial access vector the ransomware used. B (Rotate all privileged account credentials) is correct because ransomware operators often harvest credentials for lateral movement and persistence, so resetting privileged passwords and keys invalidates stolen authentication material. E (Rebuild affected servers from clean backups) is correct because restoring systems from verified, offline, malware-free backups is a core long-term containment and recovery action that eliminates the encrypted/compromised state. C (Isolate the infected systems from the network) is not part of long-term containment because it is a short-term containment action performed immediately to stop the spread. D (Block the ransomware's C2 domain at the firewall) is not long-term containment because it is a short-term containment/eradication measure that only blocks one known indicator rather than addressing the root cause.
An incident responder needs to collect memory from a Linux system during an incident. Which tool should the responder use?
Explanation: LiME (Linux Memory Extractor) is the correct tool because it is specifically designed to capture volatile memory from Linux systems, loading as a kernel module to safely dump RAM contents. During incident response, memory acquisition must be performed with minimal system interference, and LiME supports both raw and compressed output formats suitable for analysis with tools like Volatility.
An analyst is investigating a suspected data breach and needs to preserve network logs. Which of the following actions is MOST appropriate?
Explanation: Preserving network logs is best accomplished by forwarding them to a remote syslog server. This maintains a centralized, unaltered copy that is less likely to be tampered with or lost. Packet capture collects live traffic and does not preserve existing logs.

Practice all Incident Response and Management questions1. Baseline your knowledge
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 CS0-004 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+ CS0-004 blueprint. Practicing with targeted Incident Response and Management questions ensures you can handle any format or difficulty that appears.
