NSE5_FNC_AD_7.6 Exam Dumps : Fortinet NSE 5 - FortiNAC-F 7.6 Administrator

The correct answers are A and C . Fortinet’s FortiNAC-F 7.6 documentation states that, to receive and interpret traps from devices or applications, those devices or applications must be modeled in FortiNAC and must have an associated IP address. That validates option A directly. The same Fortinet Trap MIB Files documentation also lists a FortiNAC-OS requirement: the snmp option must be included in the set allowaccess command. That validates option C .

Option B is wrong because Trap MIB integration is not limited to SNMPv3. Fortinet states that Trap MIB supports receiving SNMPv1 and SNMPv2 traps from external devices, while SNMPv3 is discussed separately for traps that populate host and user records.

Option D is the trap. The Fortinet documentation explicitly says IP address OID, MAC address OID, and user ID OID are not all required ; any one OID can be used to identify the host or user that triggered the trap. So the statement that both the IP address OID and MAC address OID must be configured is false.

When FortiNAC-F manages VPN clients through a FortiGate, the agent plays a fundamental role in device identification that standard network protocols cannot provide on their own. In a standard VPN connection, the FortiGate establishes a Layer 3 tunnel and assigns a virtual IP address to the client. While the FortiGate sends a syslog message to FortiNAC-F containing the username and this assigned IP address, it typically does not provide the hardware (MAC) address of the remote endpoint ' s physical or virtual adapter.

FortiNAC-F relies on theMAC addressas the primary unique identifier for all host records in its database. Without the MAC address, FortiNAC-F cannot correlate the incoming VPN session with an existing host record to apply specific policies or track the device ' s history. By running either a Persistent or Dissolvable Agent, the endpoint retrieves its own MAC address and communicates it directly to the FortiNAC-F service interface. This allows the " IP to MAC " mapping to occur. Once FortiNAC-F has both the IP and the MAC, it can successfully identify the device, verify its status, and send the appropriateFSSO tagsor group information back to the FortiGate to lift network restrictions.

Furthermore, while the agent can also perform compliance checks (Option D), the architectural requirement for the agent in a managed VPN environment is primarily driven by the need for session data correlation—specifically the collection of the IP and MAC address pairing.

" Session Data Components: • User ID (collected via RADIUS, syslog and API from the FortiGate). • Remote IP address for the remote user connection (collected via syslog and API from the FortiGate and from the FortiNAC agent). •Device IP and MAC address (collected via FortiNAC agent).... The Agent is used to provide the MAC address of the connecting VPN user (IP to MAC). " —FortiNAC-F FortiGate VPN Integration Guide: How it Works Section.

The correct answer is A . When FortiNAC-F needs near real-time Layer 2 visibility, it relies on link traps, MAC notification traps, RADIUS, or scheduled/manual Layer 2 polling. The study guide explains that MAC notification traps contain the MAC address learned or removed from the switch MAC address table and the associated port, allowing FortiNAC-F to update its database when hosts connect, disconnect, or move. It also states that MAC notification traps are the preferred method for learning and updating Layer 2 information.

If a newly modeled switch does not show hosts as they connect or move between ports, the likely problem is that MAC notification traps are not correctly configured or not reaching FortiNAC-F . Layer 3 polling failure would affect IP-to-MAC correlation, not the ability to learn which switch port a MAC address is connected to. Disabled scheduled polling could delay updates, but it would not be the best explanation when the expected behavior is immediate host detection during connection or movement testing. Contact polling only checks whether the device is reachable; it does not collect host MAC-to-port visibility.
