A security analyst is acquiring data from a potential network incident. Which of the following evidence is the analyst MOST likely to obtain to determine the incident?

Volatile memory capture is crucial for host-based forensic analysis to identify running processes, open network connections, and malware resident in RAM, but it does not directly capture the historical network traffic or logs needed to understand a network incident's broader scope.

Network traffic (e.g., packet captures, NetFlow) provides direct visibility into the communications occurring on the network, revealing malicious payloads, unauthorized connections, and data exfiltration attempts. Logs from network devices (firewalls, routers, IDS/IPS), servers, and applications offer chronological records of events, connections, and system activities, which are critical for reconstructing the incident timeline, identifying affected systems, and understanding the attacker's actions at the network level.
