A. B. C. D.D.
The Distributed Firewall (DFW) is a component of VMware NSX-T Data Center that provides granular and scalable micro-segmentation security to virtualized workloads. It allows administrators to create and enforce firewall rules at the virtual NIC level, which provides visibility and control over east-west traffic within the data center.
In this scenario, the NSX administrator has noticed that Distributed Firewall Rules hit counts are not being logged in the syslog. This means that the syslog is not capturing information about the number of times each firewall rule is being matched, and therefore the administrator cannot monitor and troubleshoot the effectiveness of the firewall policies.
To troubleshoot this issue, the administrator should first check the configuration of the syslog on both the NSX Manager and the ESXi transport nodes. It is possible that the syslog is not configured properly, or that the configuration is incorrect. If syslog is not configured on the NSX Manager or the ESXi transport nodes, then option A or D respectively could be the cause of the issue.
If syslog is properly configured on both the NSX Manager and the ESXi transport nodes, then the administrator should check if Distributed Firewall Rule logging is enabled. If logging is not enabled, then option B could be the cause of the issue.
Finally, if syslog and Distributed Firewall Rule logging are properly configured and enabled, but the issue persists, then the administrator should review the configuration of Zero Trust Security. If Zero Trust Security is not enabled, then option C could be the cause of the issue. However, it is less likely to be the issue because Zero Trust Security is not directly related to Distributed Firewall Rule logging.
In summary, the most likely cause of Distributed Firewall Rules hit counts not being logged in the syslog is either the syslog is not configured on the NSX Manager or ESXi transport node, or Distributed Firewall Rule logging is not enabled.
