サンプル問題 1： A network engineer is deploying FortiGate devices using zero-touch provisioning (ZTP). The devices must automatically connect to FortiManager and receive their configurations upon first boot. However, after powering on the devices, they fail to register with FortiManager. What could be a possible cause of this issue?
A: The FortiGate device requires manual intervention to accept the FortiManager connection.
B: In this scenario, the ZTP process works only when devices are connected using a console cable.
C: The FortiGate device must be preloaded with a configuration file before ZTP can function.
D: The FortiManager IP address is not reachable over TCP port 541.
正解：D
Explanation: Zero-Touch Provisioning (ZTP) for FortiGate devices is handled throughFortiDeploy, which automatically connects a FortiGate toFortiManagerso the device can download configuration templates and be centrally managed. For ZTP to work, the newly booted FortiGate must successfully reach FortiManager. One of thecritical requirementsis connectivity over theFGFM (FortiGateCFortiManager) management protocol, which uses: TCP Port 541 This is clearly stated in multiple Fortinet documents: FortiGate Cloud Admin Guidelists port541as the management channel used for FortiGate → FortiManager / FortiGate Cloud communications:“Management... Protocol: TCP, Port:541” FortiOS Administration Guidealso confirms this:“FortiManager provides remote management of FortiGate devices overTCP port 541.” Since ZTP uses FortiDeploy to push the FortiManager IP to the device and relies on FGFM (port 541) for registration and configuration delivery,any failure on this port breaks the entire ZTP workflow. Why option D is correct If the FortiGate cannot reach FortiManager onTCP/541, itcannot register, cannot be authorized, and cannot receive its configuration ― leading to a ZTP failure. This is themost common causein real deployments: Firewall blocking TCP/541 Upstream NAT device not forwarding 541 ISP restrictions Incorrect FortiManager IP or routing issue ZTP device behind a network that does not allow outbound 541 Why the other options are incorrect A. The FortiGate device requires manual intervention to accept the FortiManager connection. Incorrect. ZTP is built specifically to avoid manual intervention. Once the FortiDeploy key is used, the device auto-connects to FortiManager without needing local acceptance. B. ZTP works only when devices are connected using a console cable. Incorrect. ZTP requiresno console cable― that's the whole point. It relies on DHCP, WAN connectivity, and FortiDeploy auto-join. C. The FortiGate device must be preloaded with a configuration file before ZTP can function. Incorrect. Preloading configuration defeats the purpose of ZTP. ZTP delivers the initial configuration automatically from FortiManager using FortiDeploy. LAN Edge 7.6 Architect Context LAN Edge deployments often use FortiManager as the central orchestrator for: FortiSwitch management via FortiLink FortiAP wireless provisioning SD-Branch configuration templates Security Fabric automation For all of this, ZTP enables remote sites to deploy FortiGate, FortiSwitch, and FortiAP withno on-site expertise. If TCP/541 to FortiManager is blocked, the entire LAN Edge deployment pipeline fails, making optionDthe only valid and document-supported answer
サンプル問題 2： Which FortiGuard licenses are required for FortiLink device detection to enable device identification and vulnerability detection?
A: FortiGuard Vulnerability Management and FortiGuard Endpoit Protection
B: FortiGuard Threat Intelligence and FortiGuard loT Detection
C: FortiGuard Threat Intelligence and FortiGuard Endpoint Protection
D: FortiGuard Attack Surface Security and FortiGuard loT Detection
正解：D
Explanation: FortiLink device detection relies on FortiGate'sDevice IdentificationandIoT Detectioncapabilities to classify devices connected to FortiSwitch ports. To enabledevice identificationandvulnerability detectionfor IoT/endpoint devices in LAN Edge deployments, FortiGate must subscribe to the correct FortiGuard services.
サンプル問題 3： What is the primary function of FortiLink NAC in a LAN environment?
A: To extend security policies across FortiGate firewalls only
B: To automate device onboarding and verify security posture
C: To manage FortiSwitch devices and apply manual firewall rules
D: To ensure devices are manually placed in VLANs based on their user roles
正解：B
Explanation: FortiLink NACis the NAC (Network Access Control) engine built into FortiGate when it manages FortiSwitch devices. It performs: ✔ Automated device onboarding Automatically detects new devices connecting to switches. Uses MAC, vendor, DHCP fingerprinting, or IoT database to classify devices. No manual VLAN assignment required. ✔ Security posture verification Works with FortiClient EMS, ZTNA tags, IoT detection. Applies policies based on: Device type User role Endpoint compliance IoT vulnerability status ✔ Dynamic VLAN assignment Automatically moves devices into proper VLANs, quarantine networks, or guest zones. ✔ Integration with LAN Edge & Zero Trust Uses FortiGate + FortiSwitch + FortiAP to enforce zero-trust access. This matches the LAN Edge 7.6 Architect explanation of FortiLink NAC. ❌ Why other answers are wrong A. Extend security policies across FortiGate firewalls Not NAC. That refers to Security Fabric or SD-WAN. C. Apply manual firewall rules FortiLink NAC is specifically designed toautomateaccess control. D. Manually place devices in VLANs NAC eliminates manual VLAN assignment ― it is dynamic.
