Explanation: The device limit is a feature of the enterprise edition of FortiSIEM that restricts the number of devices that can be added to the system based on the license type. The device limit does not apply to the service provider edition, which allows unlimited devices per customer. The device limit is determined by the license type that was purchased from Fortinet, such as 100 devices, 500 devices, or unlimited devices.

Correct Answer: B

Explanation: If the Z-score for this rule is greater than or equal to three, it means that the rate of firewall connection is above the historical average value. The Z-score is a measure of how many standard deviations a value is away from the mean of a distribution. A Z-score of three or more indicates that the value is significantly higher than the mean, which implies an anomaly or deviation from normal behavior.

Correct Answer: B

Explanation: The unused events for the next three minutes for a 520 EPS license can be calculated by multiplying the licensed EPS by the time interval and subtracting the total number of events received in that interval. In this case, the calculation is: 520 x 180 - 27000 = 73460

Correct Answer: D

Explanation: The natural_id value identifies the collector in the FortiSIEM system. The natural_id is a unique identifier that is assigned to each collector during the registration process with the supervisor. The natural_id is used to associate events and performance data with the collector that collected them.

Correct Answer: B

Explanation: The syntax that will register a collector to the supervisor is phProvisionCollector --add . This command will initiate the registration process between the collector and the supervisor, and exchange certificates and configuration information. The parameter is the IP address of the supervisor node.

Correct Answer: A

Explanation: The mistake that the administrator made is that customer A and customer B have overlapping IP addresses. This will cause confusion and errors in event collection and correlation, as well as CMDB discovery and classification. To avoid this problem, each customer should have a unique IP address range or use NAT to translate their IP addresses.

Correct Answer: A

Explanation: You can invoke an integration policy on FortiSIEM rules by configuring the Notification Policy settings. You can select an integration policy from the drop-down list and specify the conditions for triggering it. For example, you can invoke an integration policy when an incident is created, updated, or closed. References: Fortinet NSE 7 - Advanced Analytics 6.3 escription, page 9

Correct Answer: D

Explanation: The windows device is still in the CMDB, even though the administrator uninstalled the windows agent, because the device must be deleted manually from the CMDB. Uninstalling the windows agent does not automatically remove the device from the CMDB, as there may be other sources of data for the device, such as SNMP or syslog. To delete the device from the CMDB, the administrator must go to CMDB > Devices > All Devices, select the device, and click Delete.

Correct Answer: B

Explanation: By default, the maximum number of event files stored on the collector in the event of a WAN link failure between the collector and the supervisor is 10.000. This value can be changed in the collector.properties file by modifying the parameter max_event_files_to_store. References: Fortinet NSE 7 - Advanced Analytics 6.3 escription, page 13
