Explanation
The correct answers are A. Files and anti-malware (file) events from the NSX Edge nodes and the Security Analyzer, D. IDS/IPS events from the ESXi hosts and NSX Edge nodes, and E. Suspicious Traffic Detection events from NSX Intelligence. According to the VMware NSX Documentation3, these are the three data collection sources that are used by NSX Network Detection and Response to create correlations/intrusion campaigns.
The other options are incorrect or not supported by NSX Network Detection and Response. East-West anti-malware events from the ESXi hosts are not collected by NSX Network Detection and Response3. Distributed Firewall flow data from the ESXi hosts are not used for correlation/intrusion campaigns by NSX Network Detection and Response3.
