The correct answer is C.
OBJ-4.2: A cybersecurity analyst must preserve evidence during the containment, eradication, and recovery phase. They must preserve forensic and incident information for future needs, prevent future attacks or bring up an attacker on criminal charges. Restoration and recovery are often prioritized over analysis by business operations personnel, but taking time to create a forensic image is crucial to preserve the evidence for further analysis and investigation. During the preparation phase, the incident response team conducts training, prepares their incident response kits, and researches threats and intelligence. During the detection and analysis phase, an organization focuses on monitoring and detecting any possible malicious events or attacks. During the post-incident activity phase, the organization conducts after-action reports, creates lessons learned, and conducts follow-up actions to better prevent another incident from occurring.
