   A security analyst notices that logs from a critical firewall are not appearing in XSIAM. The firewall is configured to send syslog to the XSIAM collector's IP address on UDP port 514. The collector service is running, and the firewall's syslog configuration shows 'sending' with no errors. What should the analyst check first to resolve the ingestion issue?

   • AReview the normalization rules to confirm the firewall's vendor is supported.
   • BVerify that the collector's UDP port 514 is listening and that no firewall policy is blocking inbound traffic to the collector.
   • CRestart the collector service to force a reconnection with the firewall.
   • DCheck the firewall's syslog format and ensure it matches the parser expected by XSIAM.

   An engineer is troubleshooting why a specific log field appears as 'unknown' in XSIAM. Which of the following is the most likely cause?

   • AThe field is encrypted and cannot be read.
   • BThe data pipeline is dropping the field due to size limits.
   • CThe field is not defined in the XSIAM data model.
   • DThe log source is not sending the field.

   A SOC team is experiencing intermittent ingestion failures from a critical log source. The Data Ingestion page shows occasional spikes in parsing errors, but the source is still sending logs. The team needs to identify the root cause and prevent future occurrences. What should they do?

   • ARestart the collector to clear any temporary issues.
   • BAnalyze the parsing error logs to identify the specific logs that are failing and the reason for the failure.
   • CIncrease the collector's buffer size to handle spikes in log volume.
   • DDisable the log source and re-enable it to reset the connection.

   A security team is troubleshooting why logs from a specific application are not being parsed correctly. The raw logs are visible in the collector, but the parsed events are missing several fields. The team has verified that the parser is correctly configured for the application's format. What should they do next?

   • ADisable and re-enable the log source to reset the parser.
   • BCheck if the application is sending logs in a different format than expected.
   • CIncrease the collector's buffer size to handle larger logs.
   • DRestart the collector to reload the parser.
