The Connections view (also referred to as the Hosts view in recent versions) is the primary real-time dashboard in FortiNAC for monitoring connected endpoints. For any given host, this view displays critical session information, including its MAC address, IP address, connected switch/port, and most importantly, the currently applied Network Access Policy and Role. An administrator troubleshooting an access issue for a specific host would consult this view first to verify which policy is actively being enforced on that host's session.

A. The Policy Logs view shows historical events of policy applications and violations, which is useful for auditing but less direct for viewing the current, active state.

C. While a host's details can be viewed, this is typically accessed by drilling down from the Connections/Hosts view. The Connections view provides the immediate, high-level answer.

D. The Port Properties view shows the configuration and status of the switch port, such as VLAN and speed, but not the logical network access policy applied to the host.

FortiNAC 7.6 Administration Guide, Page 190, "Hosts View" section: Describes the columns available in this view, including "Network Access Policy" and "Role", confirming it is the location to see the policy being applied to a host.

When a host remains in the registration VLAN after successful registration, it indicates the FortiNAC system cannot move the device to its production VLAN. This occurs when the port's default VLAN is already set to the registration VLAN (option C), preventing any VLAN change. Additionally, if another unregistered host shares the same switch port (option D), FortiNAC maintains the registration VLAN for security reasons, as it cannot selectively authorize one device while restricting another on the same physical port.

A. The wrong agent being installed would prevent successful registration completion, not cause post-registration VLAN issues.

B. No agent installation would similarly prevent registration completion rather than cause post-registration VLAN retention.

When a device profiling rule is configured with the "Registration" option set to "Manual", FortiNAC will successfully match a device to the rule and list it in the "Profiled Devices" view. However, it will not automatically register the device or move it out of the "unknown" state. The "Registration" column will show "No" to indicate that administrative action is required. An administrator must manually review and approve the device registration from the "Profiled Devices" view.

A. The "confirm device profiling rule" option is a testing feature to validate a rule's logic against the database; it does not affect live device registration.

B. If a device matches multiple rules, FortiNAC applies the one with the highest precedence. This does not inherently prevent automatic registration.

D. Persistent Agent (PA) optimization relates to how FortiNAC handles state changes for known, agented devices and is not relevant to the initial registration of unknown devices.

1. FortiNAC 7.6.0 Administration Guide, page 161, "Device Profiling Rules" section. The guide describes the "Registration" setting options: "Manual: The device is not registered. An administrator must register the device from the Profiled Devices view."

The FortiNAC-F Manager is designed to centralize the management of multiple Control and

Application (CA) appliances, ensuring consistent security posture across a distributed enterprise. To

achieve this, the Manager allows administrators to define and distribute specific types of policies

globally rather than configuring them on each individual CA.

According to the FortiNAC Manager Guide, the two primary policy types that are managed globally

are:

Network Access Policies (D): These policies define the "If-Then" logic for network entry. By managing

these at the global level, an administrator can ensure that a "Contractor" receives the same

restricted access regardless of which branch office or campus they connect to.

Endpoint Compliance Policies (B): Global management of compliance policies—which consist of

scans and configurations—allows for a unified security baseline. For example, a global policy can

mandate that all Windows devices across the entire organization must have a specific antivirus

version installed and active before gaining access to the production network.

While the Manager provides visibility into authentication events and can synchronize directory data,

the specific Authentication (A) configurations (like local RADIUS secrets or specific LDAP server links)

are often localized to the CA to account for site-specific infrastructure. Supplicant EasyConnect (C) is

a feature set for onboarding, but the structural "Global Policy" engine focuses primarily on the

Access and Compliance frameworks.

"The FortiNAC Manager enables Global Policy Management, allowing for the creation and

distribution of policies across all managed CA appliances. This includes Network Access Policies,

which control VLAN and ACL assignment, and Endpoint Compliance Policies, which define the

security requirements for hosts. Centralizing these policies ensures that security standards are

enforced uniformly across the global network fabric." — FortiNAC Manager Administration Guide:

Global Policy Management Overview.

In FortiNAC-F, the Conference Manager is a specialized administrative role designed for delegated

administration, often used by receptionists or event organizers to create temporary guest accounts.

To maintain security and prevent the over-provisioning of credentials, FortiNAC-F allows for granular

restrictions on these accounts.

According to the FortiNAC-F Administration Guide regarding Administrative Profiles, when an

administrator creates a profile for a Conference Manager, they can define specific "Account Limits."

Under the profile settings (located in System > Settings > Admin Profiles), there is a field specifically

for "Max Accounts." By entering "30" into this field, the administrator ensures that any user assigned

to this profile cannot exceed 30 active conference accounts at any given time.

This setting is distinct from the Portal configuration or the Guest templates. While templates define

the type of account (e.g., duration and access level), the Administrative Profile defines the

capabilities and limitations of the person creating those accounts. This ensures that even if a guest

template allows for unlimited registrations, the specific administrator is physically restricted by the

system from generating more than the allotted 30.

"Administrative Profiles define what an administrator can see and do within the system. For

delegated administration roles like the Conference Manager, the 'Max Accounts' field in the

Administrative Profile is used to specify the maximum number of accounts the user is permitted to

create. Once this limit is reached, the user will be unable to generate additional accounts until

existing ones expire or are deleted." — FortiNAC-F Administration Guide: Administrative Profiles and

Delegated Administration.

FortiNAC uses a ranking system to resolve conflicts when a port or device belongs to multiple groups with competing enforcement policies. Each group is assigned a rank, which is a numerical value. The group with the highest priority (represented by the lowest numerical rank value) will have its policy applied. Therefore, if a port is in both the "Forced Registration" and "Forced Remediation" groups, only the policy of the group with the lower rank number will be enforced.

A. Applying both enforcement actions simultaneously would be contradictory and is not how FortiNAC handles policy conflicts.

B. Enforcement is based on the group's configuration and the host's state, not exclusively limited to rogue hosts.

C. FortiNAC allows a port to be a member of multiple enforcement groups and uses a ranking system to determine precedence.

FortiNAC integrates with third-party Mobile Device Management (MDM) solutions by acting as a REST API client. It queries the MDM server's API to retrieve device details, such as compliance status, ownership, and other attributes. If communication between FortiNAC and the MDM is failing, the most probable cause is an issue with this REST API communication. This could be due to incorrect credentials, firewall rules blocking HTTPS traffic, or incorrect API endpoint configuration.

A. Security Fabric integration is specific to Fortinet products. Communication with a third-party MDM is a direct integration and does not rely on the Security Fabric.

B. SSH is a protocol used for secure command-line access to network devices like switches and routers, not for API-based communication with management platforms.

D. While SOAP is an API protocol, FortiNAC's documented method for integrating with modern MDM platforms like Microsoft Intune or VMware Workspace ONE is via REST API.

1. FortiNAC 7.6.0 Administration Guide, page 401, "MDM Server Integration" section. The guide details configuring the connection to MDM servers, stating, "FortiNAC acts as a REST API client to the MDM server."

2. FortiNAC Integration Guide for Microsoft Intune 7.6.0, page 5, "Overview" section. It describes the integration as FortiNAC using the Microsoft Graph REST API to query Intune.

The FortiNAC-F Manager (FortiNAC-M) is designed as a centralized management platform for large-

scale distributed environments where multiple FortiNAC-F Control and Application (CA) appliances

are deployed across different sites. According to the FortiNAC-F Manager Administration Guide, the

deployment of a Manager simplifies administrative overhead in three specific ways:

First, it provides Global Version Control (B). The Manager serves as a central repository for firmware

and software updates, allowing administrators to push specific versions to all managed CAs

simultaneously, ensuring consistency across the entire fabric. Second, it enables Pooled Licenses (D).

Instead of purchasing and managing individual licenses for every CA, licenses are centralized on the

Manager. The Manager then distributes these licenses to the CAs as needed based on their host

counts. This "floating" license model optimizes cost and prevents individual sites from running out of

capacity while others have excess. Third, it offers Global Visibility (E). The Manager aggregates host

and device data from every managed CA into a single console. This "single pane of glass" allows an

administrator to search for a specific MAC address or user across the entire global organization

without logging into individual servers.

While the Manager can assist with configuration templates, authentication security policies (C) and

infrastructure modeling (A) are still predominantly managed at the local CA level to ensure site-

specific logic and performance.

"The FortiNAC Manager provides a central management console for multiple FortiNAC-F servers

(CAs). Key benefits include: • License Management: Licenses are pooled on the Manager and

allocated to managed CAs as needed. • Software Management: Firmware updates can be centrally

managed and pushed to all CAs from the Manager. • Centralized Monitoring: Provides a global view

of all hosts, adapters, and events across the entire managed environment." — FortiNAC-F Manager

Administration Guide: Overview and Benefits.

When creating user or host profiles in FortiNAC, you can apply criteria based on group memberships (such as Active Directory groups or local groups), attributes (like department, role, or custom attributes synchronized from directory services), and location (physical or logical network location). These criteria allow for granular policy enforcement and network access control. The profile creation process uses these elements to dynamically assign appropriate network access permissions and policies based on the user's or device's characteristics and context.

C. Adapter current VLAN - VLANs are assigned as a result of profile evaluation, not as criteria for profile creation.

D. An applied access policy - Access policies are outcomes of profile matching, not criteria for profile definition.

When FortiNAC discovers a network device using SNMP, it queries the device's sysObjectID (System Object Identifier). FortiNAC compares this OID against its internal database to identify the device's vendor, model, and capabilities. If the OID is not found in the database, FortiNAC cannot classify the device. It will appear in the inventory topology with a question mark icon, indicating it is an unknown or unsupported model.

A. The wrong SNMP community string was entered during discovery: This would cause a complete SNMP communication failure, typically represented by a red 'X' or similar error icon, not a question mark.

C. A read-only SNMP community string was used: FortiNAC can successfully identify devices using read-only SNMP. Read-write access is only required for enforcement actions, not for discovery and classification.

D. SNMP is not enabled on the switch: If SNMP is disabled, FortiNAC cannot query the device at all, resulting in a discovery failure, not an unknown device type icon.

1. FortiNAC Administration Guide 7.6, "Device Profiling" section, page 102. The guide explains, "FortiNAC uses the SNMP sysObjectID value returned by the device to determine the model."

2. FortiNAC Administration Guide 7.6, "Topology View" section, page 89. This section describes the icons, where a question mark signifies an "Unknown" device type, which occurs when the sysObjectID is not recognized.
