If a syslog server is not showing detailed TCP information, which setting is most likely not enabled?

• A. Log facility is NOT configured.
• B. TCP logging is NOT enabled.
• C. User-defined audit log is NOT configured.
• D. Log level is NOT enabled.

Answer: (D)

Logging detail depends on how verbose the logging is set to be. The log level is the switch that determines how much information is recorded. When the log level is set to a low or disabled state, the system captures only high-level events and skips the finer details, such as TCP handshakes, sequence and acknowledgment data, window sizes, retransmissions, and specific port information. In that case, a syslog server will not show detailed TCP information even if the events are occurring. Therefore, the most likely reason you’re not seeing detailed TCP data is that the log level isn’t enabled or is set too low. Turning up the verbosity to a more detailed level (for example, a debug or verbose setting) causes the system to emit the richer TCP-related messages to the syslog server. The other options affect different aspects: the log facility controls where or how logs are categorized or routed, TCP logging being enabled would allow TCP-specific entries to be logged, and a user-defined audit log governs audit events. None of these directly guarantee the presence of detailed TCP information as effectively as enabling a higher log level does.
