Free NSE6_FNC_AD-7.6 Practice Demo Questions

Below are 5 free demo questions to help you preview the practice tests:

Question 1:

Scenario: A hospital IT department connects a new batch of 50 headless cardiac monitors to their Cisco access switches. The switches are configured for RADIUS MAC Authentication Bypass (MAB). The MAC addresses of these monitors are not in the FortiGuard OUI database, but they all share a specific LLDP System Name (“CardioMon-X”). The NAC administrator creates a high-priority Device Profiling Rule matching this specific LLDP attribute, mapping it to the “Medical-Devices” profile. However, upon plugging in the devices, they are initially classified as “Rogue” and placed in the Isolation VLAN. It takes several minutes before they are finally reclassified to the correct profile.
What is the fundamental architectural reason for this delayed profiling behavior?
A. The administrator failed to enable the “Promiscuous LLDP Listener” daemon on the FortiNAC management interface, causing the appliance to silently drop all incoming LLDP broadcasts.
B. RADIUS MAB Access-Requests do not encapsulate LLDP payload data; FortiNAC must wait for the next scheduled SNMP L2 polling cycle to read the LLDP neighbor tables from the edge switch before the rule can match.
C. The Profiling Rule was created with a priority rank lower than the default “Catch-All Rogue” rule, causing FortiNAC to temporarily lock the endpoint state until a database synchronization occurs.
D. FortiNAC inherently requires a valid DHCP fingerprint (Option 55) to supplement any LLDP Profiling Rule; LLDP cannot be used as a standalone profiling attribute without a DHCP trigger.
Answer: B
Explanation:
Option B correctly identifies the protocol flow limitation in network access control. When the monitor is plugged in, the switch instantly sends a RADIUS MAB Access-Request to FortiNAC. This packet contains the MAC address, but no LLDP data. Since the MAC OUI is unknown, FortiNAC correctly classifies it as a Rogue. LLDP data is exchanged between the monitor and the switch locally. FortiNAC must actively poll the switch via SNMP to read this LLDP data. Until that SNMP polling cycle occurs (which can take minutes depending on the schedule), FortiNAC remains blind to the LLDP attribute.
Option A is a fabricated concept; FortiNAC does not listen to LLDP broadcasts natively on its NIC, it polls switches for them.
Option C is incorrect; profiling rules run top-down, but the issue here is missing data, not ranking.
Option D is incorrect; LLDP can absolutely be used as a standalone profiling attribute once the data is retrieved.

Question 2:

Scenario: A remote workforce utilizes FortiClient VPN connecting to a corporate FortiGate. FortiNAC is integrated via the Security Fabric to evaluate endpoint posture. If a remote PC lacks mandatory disk encryption, FortiNAC assigns it the “Quarantine” Logical Network, pushing the exact string “FW-Tag-Quarantine” to the FortiGate. The FortiGate possesses a firewall policy utilizing a Dynamic Address Object that matches this tag, with the action set to “DENY” for all internal resources. Despite FortiNAC successfully evaluating the PC as non-compliant and the Fabric connection showing “Up”, the remote user maintains full access to the internal network.
What is the most likely configuration error strictly isolated to the FortiGate side of the integration?
A. The FortiGate firewall policy referencing the Dynamic Address Object for “FW-Tag-Quarantine” is placed lower in the sequence than a broader, permissive rule that allows all standard VPN traffic.
B. The FortiGate administrator neglected to configure a reverse FSSO (Fortinet Single Sign-On) agent to passively authenticate the FortiNAC REST API calls.
C. FortiNAC cannot dynamically update Fabric Tags for endpoints terminating on IPsec/SSL VPN interfaces; it only supports tags for local Layer 2 MAC-based endpoints.
D. The FortiNAC Posture Evaluation engine requires an explicit “RADIUS CoA-Disconnect” action to be triggered against the VPN concentrator before Fabric Tags are actively transmitted.
Answer: A
Explanation:
Option A is the correct root cause. FortiGate firewall policies are evaluated strictly top-down. Even if FortiNAC flawlessly pushes the “FW-Tag-Quarantine” tag and the FortiGate dynamically populates the address object, if a broader firewall policy (e.g., “Allow All SSL-VPN to Internal”) exists above the Deny policy referencing the tag, the traffic will match the permissive rule first and be allowed.
Option B is incorrect; Security Fabric integrations utilize native API tokens/certificates, not legacy FSSO agents.
Option C is false; a primary use case for FortiNAC Fabric Connector integration is governing L3/L4 VPN sessions where traditional L2 enforcement is impossible.
Option D is incorrect because RADIUS CoA is a Layer 2 switch port mechanism and is entirely decoupled from the asynchronous API transmission of Fabric Tags.

Question 3:

Scenario: A global university operates five campuses. To ensure maximum survivability if the WAN links to headquarters drop, each campus has a standalone FortiNAC-F server handling local 802.1X and MAB authentications. The central IT team deploys a FortiNAC-F Manager at headquarters to centralize policy administration. The IT Director requests that if the local FortiNAC server at Campus A suffers a catastrophic hardware failure, the FortiNAC-F Manager at headquarters should automatically step in to process the edge RADIUS authentications for Campus A’s switches.
Why is this specific high-availability design invalid?
A. Configure the edge switches at Campus A to use the FortiNAC-F Manager’s IP address as the secondary RADIUS server to achieve this automated failover.
B. Enable the “Distributed RADIUS Proxy” feature on the Manager, which establishes secure IPsec tunnels to all Campus A switches to handle authentications globally.
C. This is architecturally unsupported; FortiNAC-F Manager provides centralized policy management and visibility, but it strictly does not act as a RADIUS server to process real-time edge authentications.
D. A Security Automation rule must be configured on the Manager to intercept SNMP Link-Down traps from Campus A’s server, triggering a dynamic BGP update to reroute the RADIUS traffic.
Answer: C
Explanation:
Option C correctly defines the architectural boundaries of FortiNAC-F Manager. The Manager is a central orchestration, visibility, and analytics platform. It pushes configurations down to regional servers and aggregates logs up from them. However, it does not run the radiusd daemon and cannot accept or process RADIUS Access-Requests from edge switches. To achieve authentication redundancy at Campus A, the university must deploy a local HA pair (Hot Standby or N+1) at Campus A.
Option A is invalid because pointing a switch to the Manager’s IP for RADIUS will result in dropped packets (the Manager doesn’t listen on UDP 1812).
Option B is a completely fabricated feature.
Option D is a nonsensical routing workaround that ignores the fundamental limitation that the Manager cannot process RADIUS traffic even if the traffic is routed to it.

Question 4:

Scenario: A network administrator is troubleshooting a complex 802.1X PEAP authentication failure for a specific Windows workstation. The endpoint consistently falls into a “Dead” state in the FortiNAC database. The standard GUI Event Logs merely show “Authentication Failed,” which does not provide enough granular detail regarding the exact EAP phase failure or certificate mismatch. The administrator needs to observe the raw RADIUS packet exchanges and EAP negotiation in real-time.
Which TWO of the following methods are officially supported to capture this deep, protocol-level debugging data in FortiNAC? (Choose two)
A. Access the FortiNAC CLI via SSH and execute the diagnose debug application radiusd (or equivalent underlying RADIUS debug) command to view real-time packet processing.
B. Execute a raw SQL query against the eap_transactions_log table in the MariaDB engine via the FortiNAC CLI.
C. Navigate to the FortiNAC Administration GUI under System > Settings > Logging, and enable the specific “RADIUS” output logs to write detailed EAP transactions to the server output logs.
D. Navigate to the FortiNAC-F Manager and initiate a “Distributed Packet Capture” targeting the workstation’s specific MAC address across all managed switches.
Answer: A, C
Explanation:
Options A and C are the correct troubleshooting techniques. FortiNAC utilizes an internal FreeRADIUS engine. To troubleshoot complex EAP issues, administrators can either enable detailed RADIUS logging via the GUI (Option C, which writes the raw radius debug output to the output.master log file downloadable via the GUI), or they can access the CLI and run real-time debug commands against the RADIUS daemon (Option A).
Option B is incorrect because FortiNAC does not store transient, raw EAP transaction payloads in standard MariaDB SQL tables; doing so would instantly exhaust database storage.
Option D is incorrect; FortiNAC-F Manager does not have a feature to command third-party edge switches to initiate distributed remote packet captures.

Question 5:

Scenario: A manufacturing plant integrates a specialized Operational Technology (OT) firewall with FortiNAC. The OT firewall is configured to send syslogs to FortiNAC when it detects malware traversing the industrial network. The FortiNAC administrator writes a custom Security Event Parser using a valid Regex string. When testing the Regex in the GUI’s “Parser Tester” tool against a sample syslog, it successfully extracts the offending MAC address. However, in production, when the OT firewall sends live syslogs, no isolation policies trigger, and the FortiNAC Event Logs classify the incoming syslog merely as an “Unknown Event”.
What is the critical missing configuration step causing this integration failure?
A. The OT firewall is transmitting the syslogs using UDP port 514, which FortiNAC inherently categorizes as “Unknown”; TCP port 6514 is strictly required for custom parsers.
B. The administrator failed to assign the newly created Security Event Parser to a specific Device Model or explicitly map its output to a defined internal FortiNAC Event Type.
C. The extracted MAC address contains uppercase letters (e.g., 00:1A:2B:3C:4D:5E), which the FortiNAC MariaDB database automatically rejects as invalid syntax during the event generation phase.
D. FortiNAC requires a specialized “OT Security Module” license key to convert syslogs originating from industrial control firewalls into actionable security events.
Answer: B
Explanation:
Option B correctly identifies the missing link in FortiNAC’s syslog parsing engine. Creating a Regex that successfully extracts a MAC address is only half the job. Once FortiNAC extracts the data, it needs to know what to do with it. The administrator must configure the Parser to map the parsed string to a specific internal FortiNAC Event (e.g., mapping it to a custom event called “OT-Malware-Detected”). Furthermore, the parser must be associated with the IP/Device Model of the OT firewall sending the logs. If the syslog matches a regex but isn’t mapped to an Event, FortiNAC logs it as an “Unknown Event” and Security Rules cannot trigger.
Option A is false; UDP 514 is fully supported and standard for custom parsers.
Option C is incorrect; FortiNAC handles both upper and lower case MAC address normalizations automatically.
Option D is completely fabricated; there are no specialized “OT Module” licenses required for syslog parsing.
