A FortiNAC-F port can belong to both Forced Registration and Forced Remediation system groups . These enforcement groups are not mutually exclusive and are not evaluated according to a ranking between the groups. Instead, FortiNAC-F determines the applicable enforcement according to the state of each host connected through that point of connection .

The Study Guide explicitly demonstrates overlapping enforcement membership: all Building 1 ports are members of Forced Registration , while second- and third-floor ports are additionally members of Forced Remediation .

FortiNAC-F then applies state-specific logic:

A rogue/unregistered host on the port satisfies Forced Registration and is moved to the Registration isolation network.

An at-risk host on the same port satisfies Forced Remediation and is moved to the Quarantine/Remediation isolation network.

The exhibit is particularly relevant because the highlighted port shows Multiple Hosts connected. Each host is evaluated independently according to its state, so different enforcement mechanisms can apply to different endpoints sharing that port.

Therefore, placing the port in both groups enables both types of enforcement , depending on the state of the connected hosts.

In FortiNAC-F, theNetwork Sessionsview provides a real-time and historical log of traffic flows, including source/destination IP addresses, ports, and protocols. This data is essential for buildingDevice Profiling Rulesthat rely on " Traffic Patterns " or " Network Footprints " to identify devices (e.g., an IP camera communicating with its specific NVR). If the network session view is empty, the system is not receiving the necessary flow or session data from the network infrastructure.

According to theFortiNAC-F Administration Guide, there are two primary methods to populate this view:

NetFlow/sFlow/IPFIX (C):FortiNAC-F can act as a flow collector. By enablingNetFlowsettings on the FortiNAC-F service interface (port2/eth1) and configuring your switches or routers to export flow data to the FortiNAC IP, the system can parse these packets and record sessions.

Firewall Session Polling (B):For environments with FortiGate firewalls, FortiNAC-F can proactively poll the FortiGate via theREST APIto retrieve its current session table. This is particularly useful as it provides session visibility without requiring the overhead of configuring NetFlow on every access layer switch.

Settings likeLayer 3 Polling(D) only provide ARP table mappings (IP to MAC correlation) and do not provide the detailed flow information required for the session view.

" TheNetwork Sessionsview displays information regarding active and inactive network traffic sessions... To populate this view, FortiNAC must receive data through one of the following methods: •NetFlow/sFlow Support: Configure network devices to send flow data to the FortiNAC service interface. •Firewall Session Polling: Enable session polling on modeled FortiGate devices to retrieve session information via API. These records are then used by the Device Profiler to match rules based on traffic patterns. " —FortiNAC-F Administration Guide: Network Sessions and Flow Data Collection.

In a1+1 High Availability (HA)deployment, FortiNAC-F supports two primary methods for management access: individual IP addresses or aShared IP Address(also known as a Virtual IP or VIP). The Shared IP option is part of aLayer 2 HAdesign, which simplifies administration by providing a single URL or IP that always points to whichever appliance is currently in the " Active " or " In Control " state.

For a Shared IP configuration to function correctly, thePrimary and Secondary administrative interfaces (port1) must be on the same subnet. This requirement exists because the Shared IP is a logical address that is dynamically assigned to the physical interface of the active unit. Since only one unit can own the IP at a time, both units must reside on the same broadcast domain (Layer 2) to ensure that ARP requests for the Shared IP are correctly answered and that the gateway remains reachable regardless of which unit is active. If the appliances were on different subnets (a Layer 3 HA design), a shared IP could not be used because it cannot " float " across different network segments; instead, administrators would need to manage each unit via its unique physical IP or use a FortiNAC Manager.

" For L2 HA configurations, click theUse Shared IP Addresscheckbox and enter the Shared IP Address information...If your Primary and Secondary Servers are not in the same subnet, do not use a shared IP address.The shared IP address moves between appliances during a failover and recovery and requires both units to reside on the same network. " —FortiNAC-F High Availability Reference Manual: Shared IP Configuration.

The correct answer is C . The Port Changes view is the correct troubleshooting location when FortiNAC-F changes endpoint network access, such as moving a switch port into a different VLAN. The study guide states that any time FortiNAC-F changes network access for an endpoint, the change is documented in Network > Port Changes . This view shows the date and time of the change, whether a CLI configuration was executed, the reason for the change, the role or access policy that caused it, the port that was changed, and the VLAN the port was changed to.

This directly matches the troubleshooting requirement in the question: the administrator needs to know when the VLAN change happened and why FortiNAC-F made that network access decision. Option A , Security Event view, is used for security-related events, not detailed port-level VLAN-change history. Option B , Reports view, is too broad and not the operational audit trail for a specific access change. Option D , Admin Auditing, tracks administrative actions, but an automatic policy-driven VLAN assignment is documented under Port Changes, not primarily as an admin audit event.

The correct answer is D . The log output shows the local IP address as 192.168.10.10 , which the question identifies as the primary FortiNAC-F server. In the same output, FortiNAC-F reports inControl true and controlServer true , which means the local primary server is currently the control server. The line showing communication to 192.168.10.110 returns Running - Not In Control , confirming that the secondary server is alive but is not the active controlling node.

This matches FortiNAC-F 1+1 HA behavior. The study guide describes a 1+1 HA pair as an active-passive deployment where one FortiNAC-F device is designated primary and the other secondary. Database and configuration synchronization keep the devices aligned, but only one server is in control at a time. If the primary fails, the secondary assumes control automatically; otherwise, the primary remains the active control server.

Option A is wrong because the secondary explicitly reports Not In Control . Option B is wrong because the output does not show database replication failure. Option C is wrong because failover is not in progress; the output shows a stable state where the primary is in control and the secondary is running as the passive node.

In FortiNAC-F, the expiration of a guest or contractor account is determined by the configuration settings within theAccount Creation Wizardand the associatedGuest/Contractor Template. While a template can define a default " Account Duration " (as seen in the 12-hour setting in the second exhibit), theAccount Creation Wizardallows an administrator to manually specify or override the start and end parameters for a specific user session.

According to theFortiNAC-F Administration Guideregarding guest management, theAccount End Datefield in the creation wizard is the definitive timestamp for when the account object will be disabled or deleted from the system. In the provided exhibit (Account Creation Wizard), the administrator has explicitly set theAccount Start Dateto2025/09/12 08:00:00and theAccount End Dateto2025/09/13 17:00:00.

Even though the template indicates an " Account Duration " of 12 hours, this value typically serves as a pre-populated default. When a manual date and time are entered into the wizard, those specific values take precedence for that individual account. The account will remain active and valid until5:00 PM (17:00:00)on the following day,2025/09/13. It is also important to note the " Login Availability " from the template (8:00 AM - 7:00 PM); while the accountexistsuntil the 13th at 17:00:00, the user would only be able to authenticate during the active hours defined by the login schedule on both days.

" When creating an account, the administrator can select a template to provide default settings. However, specific values such as theAccount End Datecan be modified within theAccount Creation Wizard. The date and time specified in the ' Account End Date ' field determines the absolute expiration of the account. Once this time is reached, the account is moved to an expired state and the user ' s network access is revoked. " —FortiNAC-F Administration Guide: Guest and Contractor Account Management.

The correct answer is A . In FortiNAC-F, device profiling rules are used primarily to classify unknown or untrusted devices when they are first discovered. The study guide explains that when a device does not already exist in the database, FortiNAC-F adds it, treats it as a rogue, and evaluates it against enabled device profiling rules. It also states that devices are initially evaluated against device profiling rules only if they do not already exist in the database, because this avoids unnecessary repeated evaluation of known devices.

The exhibit also matters: the rules are enabled and set to Automatic registration, but Confirm Rule On Connect is not enabled and Confirm Rule Interval is set to None . That means FortiNAC-F will not automatically revalidate already-profiled or trusted devices every time they connect. Option B is wrong because trusted devices are not repeatedly evaluated unless rule confirmation is configured. Option C is too broad because all hosts are not processed through profiling rules on every connection. Option D is also wrong because changing location does not by itself force automatic device profiling; location can be used as a rule method, but the automatic evaluation described here applies when the rogue device is initially added to the database.

The correct answer is D . In a Layer 3 registration or isolation network design, DHCP requests from the isolated registration VLAN are not served locally on that VLAN by a normal production DHCP server. Instead, the registration VLAN’s DHCP relay must forward DHCP traffic to FortiNAC-F port2 , because port2 is the captive network service interface. The study guide states that in Layer 3 captive networks, DHCP traffic is relayed to port2 from the captive networks, and that the FortiNAC-F port2 interface provides DHCP, DNS, and captive portal services for hosts assigned to those captive networks.

In the exhibit, the registration VLAN is 192.168.10.x/24 , with gateway 192.168.10.254 . That gateway is where the DHCP relay would be configured, but it is not the relay destination. The relay destination must be the FortiNAC-F port2 address, shown as 192.168.200.10 . The corporate DHCP server 192.168.100.75 is for production network addressing, not registration isolation. The FortiNAC-F port1 address 192.168.100.20 is the administrative or production-facing interface, not the captive network service interface. Therefore, the DHCP relay should point to 192.168.200.10 .
