NSE6_FSM_AN-7.4 Exam Dumps - Fortinet NSE 6 - FortiSIEM 7.4 Analyst

The correct answer is A . In FortiSIEM machine learning training, the Train factor controls how much of the prepared dataset is used for training and how much is reserved for testing. The FortiSIEM 7.4 User Guide states in the regression training procedure that the analyst must choose the Train factor and that it “should be greater than 70%.” It also explains the meaning of the value: 70% of the data is used for training and 30% is used for testing. This directly supports option A. Option B is incorrect because the supported running modes include Local, Local Auto, and AWS; “ML” is not the required run mode. Option C is incorrect because regression can use multiple fields for prediction; the guide instructs the user to choose the fields to use for prediction and the field to predict. Option D is incorrect because prediction input fields and target field should not be the same. Regression builds a model to predict a target field based on other fields, so the configuration must use a valid Train factor rather than matching predictor and target fields.

The operator is set to " = " , which performs an exact match on the entire raw event log, not a substring search. To find logs that contain the keyword " udp " , the analyst should use the CONTAIN operator instead. This will return all logs where " udp " appears anywhere in the raw log message.

The correct answer is D because the analyst is trying to search for raw logs that contain the keyword udp, but the filter uses the equality operator. The FortiSIEM Study Guide explains keyword searches in terms of Raw Event Log CONTAIN logic. In the keyword phrase search section, the guide states that without quotes, FortiSIEM searches raw event logs by using conditions such as Raw Event Log CONTAIN TCP OR Raw Event Log CONTAIN connection . Another analytics example explains that searching for TCP or UDP events uses the raw event log containing the keyword tcp or udp and that the search returns case-insensitive results for TCP and UDP. This directly eliminates option C. The time range is already set to the last two hours, which is correct for historical raw log searching. The problem is the operator. To find a keyword anywhere inside a raw log message, the analyst should use CONTAIN , not =.

FortiSIEM applies tags to FortiClient EMS-managed hosts through FortiEMS integration. The FortiSIEM 7.4 User Guide states that FortiSIEM supports discovery of FortiEMS servers using the FortiEMS Management Server API with username/password authentication. That supports option A: FortiEMS API credentials must be configured on FortiSIEM. The same guide explains that after FortiEMS discovery, “FortiSIEM can tag or untag a host, using classification tags on FortiEMS server.” It further explains the ZTNA workflow: in ZTNA, these tags are imported by Fortinet devices, especially FortiGate firewalls, and referenced in ZTNA firewall rules. That supports option C: the tag value used for ZTNA classification must be available/defined for the FortiEMS tagging workflow. Option B is not the best required configuration in the question because a remediation script is an execution method, not one of the two foundational settings being asked for. Option D reverses the API relationship; FortiSIEM connects to FortiEMS using FortiEMS credentials, not FortiSIEM API credentials stored on EMS.

The exhibit shows a machine learning Regression configuration. In FortiSIEM regression, selected numerical fields are used as predictors, and another field is selected as the value to predict. The FortiSIEM 7.4 User Guide’s Machine Learning section lists Regression separately and describes the training workflow, including selecting fields used by the algorithm. The exhibit shows Memory Utilization, Sent Bytes, and Received Bytes selected under Fields to use for Prediction, while CPU Utilization is selected under Field to Predict. This means Memory Utilization is an input variable used by the model. If memory utilization is consistently high during training or retraining, that higher value becomes part of the learned model pattern. FortiSIEM does not automatically trigger a high-memory incident merely because a regression input value is high; an incident would require inference behavior and an anomaly action or rule configuration. Option C is also wrong because FortiSIEM does not dynamically lower a CPU trigger threshold just because memory is high. The correct behavior is model update based on the higher observed input value.

The correct answers are D. Run Remediation/Script and E. Run Playbook on Incident Trigger . FortiSIEM can block an IP address on a FortiGate through a remediation script or through a FortiSOAR playbook/connector workflow. The FortiSIEM Analyst Study Guide explains that for automatic remediation, you define a remediation script for a scenario, and that mitigation scripts can “block an IP address in a firewall” or disable a user in Active Directory. It also states that, when an automation policy is triggered and the remediation script option is enabled, FortiSIEM uses incident data and runs the script to quarantine or block the offending IP address on FortiGate.

FortiSIEM 7.4 also supports automatic playbook execution from an automation policy. The 7.4 User Guide states that under Admin > Settings > Automation Policy , you can choose Run Playbook on Incident Trigger and select a playbook. The same guide explains that FortiSOAR playbooks can call connectors, and the Fortinet FortiOS connector can perform actions such as Block IP Address on a FortiGate firewall.

Email, Remedy tickets, and generic integration policies are notification/ticketing workflows, not the direct FortiGate IP-block actions.

The correct answer is C. SSL . FortiSIEM receives raw logs, processes them through parsers, normalizes the extracted fields, classifies the event, and stores the structured data. The Study Guide explains the FortiSIEM process flow: data is collected, processed by the parsing engine, normalized, classified, and then stored. It further states that normalization extracts individual fields from raw events and maps those fields to a common schema. The FortiSIEM 7.4 User Guide describes a parser as a file containing instructions for the parser module to convert a raw log into event attributes. In the exhibit, the raw FortiGate log includes values such as profiletype= " applist " , appcat= " Network.Service " , and app= " SSL " . The field that directly represents the application value is app= " SSL " . Therefore, the parser would use SSL to populate the normalized Application Name field. applist describes the profile type, Network.Service is the application category, and wan1 is the interface, not the application name.
