質問 # 11
Which discovery scan type is prone to miss a device, if the device is quiet and the entry foe that device is not present in the ARP table of adjacent devices?
- A. Range scan
- B. CMDB scan
- C. L2 scan
- D. Smart scan
正解：C
解説：
Discovery Scan Types: FortiSIEM uses various scan types to discover devices on a network.
Layer 2 (L2) Scan: An L2 scan discovers devices based on ARP tables and MAC address information from adjacent devices.
* Limitation: If a device is quiet (not actively communicating) and its entry is not present in the ARP table of adjacent devices, the L2 scan may miss it.
Other Scan Types:
* CMDB Scan: Based on the existing Configuration Management Database (CMDB) entries.
* Range Scan: Scans a specified IP range for devices.
* Smart Scan: Uses a combination of methods to discover devices.
References: FortiSIEM 6.3 User Guide, Device Discovery section, which explains the different types of discovery scans and their characteristics.

質問 # 14
Which process converts raw log data to structured data?
- A. Data parsing
- B. Data enrichment
- C. Data validation
- D. Data classification
正解：A
解説：
Raw Log Data: When devices send logs to FortiSIEM, the data arrives in a raw, unstructured format.
Data Parsing Process: The process that converts this raw log data into a structured format is known as data parsing.
* Data Parsing: This involves extracting relevant fields from the raw log entries and organizing them into a structured format, making the data usable for analysis, reporting, and correlation.
Significance of Structured Data: Structured data is essential for effective event correlation, alerting, and generating meaningful reports.
References: FortiSIEM 6.3 User Guide, Data Parsing section, which details how raw log data is transformed into structured data through parsing.

質問 # 16
Which is a requirement for implementing FortiSIEM disaster recovery?
- A. DNS names must be used for the worker upload addresses.
- B. The two supervisor nodes must have layer 2 connectivity.
- C. SNMP, and WMI ports must be open between the two supervisor nodes.
- D. All worker nodes must access both supervisor nodes using IP.
正解：A
解説：
Disaster Recovery (DR) Implementation: For FortiSIEM to effectively support disaster recovery, specific requirements must be met to ensure seamless failover and data integrity.
Layer 2 Connectivity: One of the critical requirements for implementing FortiSIEM DR is that the two supervisor nodes must have layer 2 connectivity.
* Layer 2 Connectivity: This ensures that the supervisors can communicate directly at the data link layer, which is necessary for synchronous data replication and other DR processes.
Importance of Connectivity: Layer 2 connectivity between the supervisor nodes ensures that they can maintain consistent and up-to-date state information, which is essential for a smooth failover in the event of a disaster.
References: FortiSIEM 6.3 Administration Guide, Disaster Recovery section, which details the requirements and configurations needed for setting up disaster recovery, including the necessity for layer 2 connectivity between supervisor nodes.

質問 # 18
If an incident's status is Cleared, what does this mean?
- A. The incident was cleared by an operator.
- B. A security rule issue has been resolved.
- C. Two hours have passed since the incident occurred and the incident has not reoccurred.
- D. A clear condition set on a rule was satisfied.
正解：D
解説：
Incident Status in FortiSIEM: The status of an incident indicates its current state and helps administrators track and manage incidents effectively.
Cleared Status: When an incident's status is "Cleared," it means that a specific condition set to clear the incident has been satisfied.
* Clear Condition: This is typically a predefined condition that indicates the issue causing the incident has been resolved or no longer exists.
Automatic vs. Manual Clearance: While some incidents may be cleared automatically based on clear conditions, others might be manually cleared by an operator.
References: FortiSIEM 6.3 User Guide, Incident Management section, detailing the various incident statuses and the conditions that lead to an incident being marked as "Cleared."

質問 # 20
An administrator defines SMTP as a critical process on a Linux server.
It the SMTP process is stopped. FortiSIEM will generate a critical event with which event type?
- A. Generic_SMTP_Procoss_Exit
- B. Postfix-Mail-Stop
- C. PH_DEV_MON_PROC_STOP
- D. PH_DEV_MON_SMTP_STOP
正解：C
解説：
Process Monitoring in FortiSIEM: FortiSIEM can monitor critical processes on managed devices, such as an SMTP process on a Linux server.
Event Generation: When a critical process stops, FortiSIEM generates an event to alert administrators.
Event Types: Specific event types correspond to different monitored conditions. For a stopped process, the event typePH_DEV_MON_PROC_STOPis used.
Reasoning: The namePH_DEV_MON_PROC_STOP(Device Monitoring Process Stop) is a generic event type used by FortiSIEM to indicate that any monitored process, including SMTP, has stopped.
References: FortiSIEM 6.3 User Guide, Event Types section, explains the predefined event types and their usage in different monitoring scenarios.
質問 # 21
Refer to the exhibits.
Three events are collected over a 10-minute time period from two servers: Server A and Server B.
Based on thesettings tor the rule subpattern. how many incidents will the servers generate?
- A. Server A will generate one incident and Server B will not generate any incidents.
- B. Server A will generate one incident and Server B will generate one incident.
- C. Server B will generate one incident and Server A will not generate any incidents.
- D. Server A will not generate any incidents and Server B will not generate any incidents.
正解：A
解説：
Event Collection Overview: The exhibits show three events collected over a 10-minute period from two servers, Server A and Server B.
Rule Subpattern Settings: The rule subpattern specifies two conditions:
* AVG(CPU Util) > DeviceToCMDBAttr(Host IP : Server CPU Util Critical Threshold): This checks if the average CPU utilization exceeds the critical threshold defined for each server.
* COUNT(Matched Events) >= 2: This requires at least two matching events within the specified period.
Server A Analysis:
* Events: Three events (CPU=90, CPU=90, CPU=95).
* Average CPU Utilization: (90+90+95)/3 = 91.67, which exceeds the critical threshold of 90.
* Matched Events Count: 3, which meets the condition of being greater than or equal to 2.
* Incident Generation: Server A meets both conditions, so it generates one incident.
Server B Analysis:
* Events: Three events (CPU=70, CPU=50, CPU=60).
* Average CPU Utilization: (70+50+60)/3 = 60, which does not exceed the critical threshold of 90.
* Matched Events Count: 3, but since the average CPU utilization condition is not met, no incident is generated.
Conclusion: Based on the rule subpattern, Server A will generate one incident, and Server B will not generate any incidents.
References: FortiSIEM 6.3 User Guide, Event Correlation Rules and Incident Management sections, which explain how incidents are generated based on rule subpatterns and event conditions.
質問 # 22
Refer to the exhibit.
Which section contains the sortings that determine how many incidents are created?
- A. Actions
- B. Filters
- C. Group By
- D. Aggregate
正解：D
解説：
Incident Creation in FortiSIEM: Incidents in FortiSIEM are created based on specific patterns and conditions defined within the system.
Group By Function: The "Group By" section in the "Edit SubPattern" window specifies how the data should be grouped for analysis and incident creation.
Impact of Grouping: The way data is grouped affects the number of incidents generated. Each unique combination of the grouped attributes results in a separate incident.
Exhibit Analysis: In the provided exhibit, the "Group By" section lists "Reporting Device," "Reporting IP," and "User." This means incidents will be created for each unique combination of these attributes.
References: FortiSIEM 6.3 User Guide, Rule and Pattern Creation section, which details how grouping impacts incident generation.
質問 # 23
FortiSIEM is deployed in disaster recovery mode.
When disaster strikes, which two tasks must you perform manually to achieve a successful disaster recovery operation? (Choose two.)
- A. Promote the secondary supervisor to the primary role using the phSecondary2primary command.
- B. Change the configuration for shared storage NFS configured for EventDB to the secondary FortiSIEM.
- C. Promote the secondary workers to the primary rotes using the phSecworker2priworker command.
- D. Change the DNS configuration to ensure that users, devices, and collectors log in to the secondary FortiSIEM.
正解：C、D
解説：
Disaster Recovery Mode: FortiSIEM's disaster recovery (DR) mode ensures that there is a backup system ready to take over in case the primary system fails.
Manual Tasks for DR Operation: In the event of a disaster, certain tasks must be performed manually to ensure a smooth transition to the secondary system.
Promoting the Secondary Supervisor:
* Use the commandphSecondary2primaryto promote the secondary supervisor to the primary role. This command reconfigures the secondary supervisor to take over as the primary supervisor, ensuring continuity in management and coordination.
Changing DNS Configuration:
* Update the DNS configuration to direct all users, devices, and collectors to the secondary FortiSIEM instance. This ensures that all components in the environment cancommunicate with the newly promoted primary supervisor without manual reconfiguration of individual devices.
References: FortiSIEM 6.3 Administration Guide, Disaster Recovery section, provides detailed steps on promoting the secondary supervisor and updating DNS configurations during a disaster recovery operation.

- B. Devices, users, high risk, and low risk
- C. Performance, devices, high risk, and low risk
- D. Performance, availability, security, and change
正解：D
質問 # 25
Refer to the exhibit.
A FortiSIEM administrator wants to group some attributes for a report, but is not able to do so successfully.
As shown in the exhibit, why are some of the fields highlighted in red?
- A. Unique attributes cannot be grouped.
- B. The Event Receive Time attribute is not available for logs.
- C. No RAW Event Log attribute is available for devices.
- D. The attribute COUNT(Matched events) is an invalid expression.
正解：A
解説：
Grouping Attributes in Reports: When creating reports in FortiSIEM, certain attributes can be grouped to summarize and organize the data.
Unique Attributes: Attributes that are unique for each event cannot be grouped because they do not provide a meaningful aggregation or summary.
Red Highlighting Explanation: The red highlighting in the exhibit indicates attributes that cannot be grouped together due to their unique nature. These unique attributes includeEvent Receive Time,Reporting IP,Event Type,Raw Event Log, andCOUNT(Matched Events).
Attribute Characteristics:
* Event Receive Timeis unique for each event.
* Reporting IPandEvent Typecan vary greatly, making grouping them impractical in this context.
* Raw Event Logrepresents the unprocessed log data, which is also unique.
* COUNT(Matched Events)is a calculated field, not suitable for grouping.
