The correct answer is A . The exhibit shows two adapters learned on the same wired port: one appears as a rogue/unknown host, and the other is associated with the Lab Hosts rule. The port is in both Role-Based Access and Forced Registration . FortiNAC-F state-based control takes precedence over policy-based provisioning, and the study guide states that when a rogue host connects to a port in the Forced Registration group, FortiNAC-F isolates that host by moving it into the registration captive network. The guide also explains that the Isolation network can be used as a single network for abnormal host states while still presenting state-specific portal pages.

Because this is a wired switch port using VLAN-based control, FortiNAC-F cannot put one host on the production VLAN and the other host on the isolation portal VLAN at the same time on the same access port. The VLAN change applies to the port, not independently to each MAC address behind that port. Therefore, the presence of the rogue host on a Forced Registration port causes the port to be provisioned to the isolation network. Option B is technically unrealistic for this access-port scenario. Option C is wrong because two MAC addresses alone do not make the port an uplink; FortiNAC-F uses uplink logic for infrastructure-device MACs, manually marked uplinks, or a threshold such as more than 20 MAC addresses. Option D is unrelated because Access Point Management is not triggered by learning two wired hosts on a port.

In a corporate domain environment where " enhanced endpoint visibility " is required, thePersistent Agentis the recommended choice. Unlike the Dissolvable Agent, which is temporary and intended for one-time compliance scans during registration, the Persistent Agent is an " install-and-stay-resident " application.

The Persistent Agent is specifically designed to be distributed through automated enterprise methods, includinglogin scripts, Group Policy Objects (GPO), or third-party software management tools. When deployed via a login script, the agent can be configured to silently install and immediately begin communicating with the FortiNAC-F service interface. Once active, it provides continuous visibility by reporting host details such as logged-on users, installed applications, and adapter information. It also listens for Windows session events (logon/logoff) to trigger automatic single-sign-on (SSO) registration in FortiNAC-F, ensuring that as soon as a user connects to the domain, their device is identified and assigned the correct network access policy.

" The Persistent Agent can be distributed to Windows domain machines vialogin scriptor by any other software distribution method your organization might use. The Persistent Agent remains installed on the host at all times. Once the agent is installed it runs in the background and communicates with FortiNAC at intervals established by the FortiNAC administrator.

In FortiNAC-F, theLayer 3 Network typeis specifically designed for deployments where the isolation networks—such as Registration, Remediation, and Dead End—are separated from the FortiNAC appliance ' s service interface (port2) by one or more routers. This architecture is common in large, distributed enterprise environments where endpoints in different physical locations or branches must be isolated into subnets that are local to their respective network equipment.

The reason the Configuration Wizard allows for more than one DHCP scope for a single isolation network type (state) is thatthere can be more than one isolation network of each typeacross the infrastructure. For instance, if an organization has three different sites, each site might require its own unique Layer 3 registration subnet to ensure efficient routing and to accommodate local IP address management. By allowing multiple scopes for the " Registration " state, FortiNAC can provide the appropriate IP address, gateway, and DNS settings to a rogue host regardless of which site ' s registration VLAN it is placed into.

When an endpoint is isolated, the network infrastructure (via DHCP Relay/IP Helper) directs the DHCP request to the FortiNAC service interface. FortiNAC then identifies which scope to use based on the incoming request ' s gateway information. This flexibility ensures that the system is not limited to a single flat subnet for each isolation state, supporting a scalable, multi-routed network topology.

" Multiple scopes are allowed for each isolation state (Registration, Remediation, Dead End, VPN, Authentication, Isolation, and Access Point Management). Within these scopes, multiple ranges in the lease pool are also permitted... This configWizard option is used when Isolation Networks are separated from the FortiNAC Appliance ' s port2 interface by a router.
