Incorrect Answers A:The appliance did not emit the expected CEF extension in the source message; the forwarder lacks the correct AMA data-collection rule association and CEF stream configuration. C:Plain Syslog and structured CEF use different supported streams and result tables; the forwarder lacks the correct AMA data-collection rule association and CEF stream configuration. D:No supported ingestion-time transformation removes unneeded properties before table storage; the forwarder lacks the correct AMA data-collection rule association and CEF stream configuration.
Question 204 During a controlled investigation, a supported CEF appliance forwards a representative event through AMA and its assigned DCR.

Incorrect Answers A:The corresponding extension value is present in the parsed CommonSecurityLog event or documented raw field; the event appears in CommonSecurityLog with the expected device/vendor fields. C:The plain event is available in Syslog and the CEF event in CommonSecurityLog with appropriate fields; the event appears in CommonSecurityLog with the expected device/vendor fields.

Question 205 A financial services SOC needs to separate unstructured Linux authentication Syslog from vendor-formatted CEF security messages. Its current security configuration cannot meet this specific operational requirement. Which action should the SOC implement? Use Syslog via AMA for the plain logs and CEF via AMA for properly formatted CEF Apply supported ingestion-time DCR transformations after validating detection needs Configure Common Event Format via AMA with an appropriate forwarding host Inspect forwarder routing and AMA/DCR association to the workspace Explanation Correct Answer A:Connector selection follows source format and destination table semantics. Incorrect Answers B:Ingestion transformations can project essential fields from the incoming records. C:CEF connectors accept structured vendor event messages through the supported syslog route. D:Connectivity and DCR scope explain missing CEF ingestion before detection logic.
Question 206 The regional SOC SOC needs to separate unstructured Linux authentication Syslog from vendor-formatted CEF security messages, and its change advisory board asks for the technical basis of the recommended method. Which explanation identifies the most relevant capability? CEF connectors accept structured vendor event messages through the supported syslog route. Correct CEF formatting determines normalized event fields. Connector selection follows source format and destination table semantics. WEF subscription filters reduce unrelated event volume. Explanation Correct Answer C:Connector selection follows source format and destination table semantics. Incorrect Answers A:Ingesting normalized CEF messages from a supported network firewall does not separate unstructured Linux authentication Syslog from vendor-formatted CEF security messages. B:Preserving vendor-defined CEF extension fields for incident queries does not separate unstructured Linux authentication Syslog from vendor-formatted CEF security messages. D:Avoiding ingesting every Windows channel when only targeted security events are needed does not separate unstructured Linux authentication Syslog from vendor-formatted CEF security messages.

D:The schema mapping or KQL refers to the old field name after the vendor schema change. Plain Syslog and structured CEF use different supported streams and result tables.
Question 208 During a controlled investigation, a Linux auth event and a CEF firewall event are each sent through their appropriate AMA connectors.
