Incorrect Answers A:Ingesting supported Linux system logs into Sentinel using Azure monitoring does not troubleshoot Linux logs missing despite an installed AMA agent. B:Identifying why a device's generic Syslog messages are not appearing in CommonSecurityLog does not troubleshoot Linux logs missing despite an installed AMA agent. C:Normalizing structured intelligence from a TAXII-compatible source does not troubleshoot Linux logs missing despite an installed AMA agent.
Question 235 An AMA service is healthy but no Linux auth messages arrive; the linked DCR has excluded the authpriv facility. Which explanation best accounts for the specific failure? The DCR's facility and log-level filters are broader than the approved scope The source lacks the CEF formatting required by the CommonSecurityLog stream The query did not join or examine a specific threat-intelligence indicator record The DCR does not collect the facility or severity emitted by the Linux source Explanation Correct Answer D:The DCR does not collect the facility or severity emitted by the Linux source. Incorrect Answers A:The DCR's facility and log-level filters are broader than the approved scope; the DCR does not collect the facility or severity emitted by the Linux source. B:The source lacks the CEF formatting required by the CommonSecurityLog stream; the DCR does not collect the facility or severity emitted by the Linux source. C:The query did not join or examine a specific threat-intelligence indicator record; the DCR does not collect the facility or severity emitted by the Linux source.
Question 236 During a controlled investigation, a Linux host emits a known authentication event under an included facility and severity. Which observation most directly verifies the intended technical behavior? The test event reaches the Syslog table and matches its configured collection filters Only matching facility/severity combinations enter the Syslog table for the controlled test The plain message appears in Syslog and the CEF-formatted message in CommonSecurityLog The result includes indicator identity, source, validity and the matching observed hash Explanation Correct Answer A:The test event reaches the Syslog table and matches its configured collection filters. Incorrect Answers B:Only matching facility/severity combinations enter the Syslog table for the controlled test; the test event reaches the Syslog table and matches its configured collection filters. C:The plain message appears in Syslog and the CEF-formatted message in CommonSecurityLog; the test event reaches the Syslog table and matches its configured collection filters. D:The result includes indicator identity, source, validity and the matching observed hash; the test event reaches the Syslog table and matches its configured collection filters.
Question 237 A insurance provider needs to identify why a device's generic Syslog messages are not appearing in CommonSecurityLog.
