This behavior directly indicates that the matching Device Profiling Rule has Registration configured as Manual . The FortiNAC-F 7.6 Administrator Study Guide explains that when registration is Automatic , FortiNAC-F performs the configured registration operations immediately after the device matches the rule. When registration is Manual , however, the rule still matches and the device is successfully profiled and classified , but the registration settings are not executed until an authorized sponsor or administrator manually registers the device.

Consequently, the device can legitimately appear in Profiled Devices with its matched rule and assigned device type while the Registered column remains No . The Administration Guide confirms that this column specifically indicates whether the profiled device has been registered.

Option A is incorrect because rule confirmation determines whether an already-profiled device is periodically or subsequently revalidated against its associated rule; it does not control initial registration. Option B is incorrect because rules are evaluated in ranked order until the applicable match is processed. Option D concerns Persistent Agent communications and does not determine device-profiler registration status.

The firewall policy for an unauthorized VPN host is an isolation policy. When a remote endpoint first establishes its VPN tunnel, FortiGate assigns the client an IP address plus two DNS servers: the production DNS server as primary and the FortiNAC-F Port2 VPN-context address as secondary . Until FortiNAC-F validates the endpoint, FortiGate firewall policies restrict the client ' s traffic so that it can communicate only with the FortiNAC-F Port2 VPN interface .

This restriction deliberately prevents access to the primary production DNS server. Consequently, DNS resolution against the primary server fails and the endpoint falls back to the secondary DNS server—FortiNAC-F. FortiNAC-F then resolves the request toward its VPN isolation interface and presents the VPN captive portal . The user can subsequently run or download the required FortiNAC-F agent, allowing FortiNAC-F to perform identification and endpoint-compliance validation.

After successful authorization, FortiNAC-F sends the appropriate group/tag information to FortiGate, causing the host to match a different firewall policy that permits the required production resources and blocks the isolation interface.

FortiNAC-F serves as a central manager for security events originating from a diverse ecosystem of third-party security appliances, such as FortiGate, Check Point, and Cisco. Each vendor utilizes its own internal scale forseverity levelswithin syslog messages (e.g., Check Point uses a 1–5 scale, while others may use 0–7). To provide a consistent response regardless of the source, FortiNAC-F usesSeverity Mappingsto normalize these incoming values.

According to theFortiNAC-F Administration Guide, severity mappings allow the administrator to translate vendor-specific threat levels into standardizedFortiNAC Security Levels(such as High, Medium, or Low Violation). When a syslog message arrives, the parser extracts the vendor ' s severity code, and the system immediately references theSecurity Event Severity Level Mappingstable to determine how that event should be categorized internally. This normalization is vital because it allows a singleSecurity Alarmto be configured to respond to any " High Violation " event, whether it was reported as a " Critical " by one vendor or a " Level 5 " by another. Without these mappings, the administrator would have to create separate, redundant security rules for every vendor to account for their different naming conventions and numerical scales.

" Each vendor defines its own severity levels for syslog messages. The following table shows the equivalent FortiNAC security level... To normalize these events, configure theSeverity Level Mappingsfound in the device integration guides. This allows FortiNAC to generate a consistent security event that can then trigger an alarm regardless of the reporting vendor ' s specific terminology. " —FortiNAC-F Administration Guide: Vendor Severity Levels and Syslog Management.

The Passive Agent is the agent specifically associated in the FortiNAC-F 7.6 curriculum with domain login/logoff scripts . The Study Guide states that the Passive Agent is “deployed by a login/logoff script” and is designed to register and scan Windows endpoints joined to a domain when a domain user logs in .

The administrator places the Passive Agent executable in a user-accessible location, such as SYSVOL , configures the FortiNAC-F server information through administrative templates, and invokes the executable through the domain controller ' s login/logoff scripts. This allows FortiNAC-F to obtain endpoint information and track users without requiring interactive installation by the user. Passive Agent configurations can register the user and associated host, perform compliance scanning if configured, and track login/logout activity.

The Administration Guide reinforces this workflow by specifying GPO User Configuration > Windows Settings > Scripts (Logon/Logoff) and using the Passive Agent with -logon and -logoff parameters.

Therefore, the exam-specific answer is Passive Agent .

In FortiNAC-F, theSecurity Incidentsengine is used to automate responses to security threats reported by external devices. When an administrator wants to enforce a policy, such as quarantining contractors who access restricted websites, they must create aSecurity Rule. A Security Rule acts as the " if-then " logic that correlates incoming security data with the internal host database.

The documentation specifies that a Security Rule consists of three primary configurable components:

User/Host Profile:This identifieswhoorwhatthe rule applies to (in this case, " Contractors " ).

Trigger:This is theeventthat initiates the rule evaluation. In this scenario, the Trigger would be configured to match specific syslog messages or NetFlow data indicating access to prohibited websites. Triggers use filters to match vendor-specific data, such as a " Web Filter " event from a FortiGate.

Action:This defineswhathappens when the Trigger and User/Host Profile are matched. For this scenario, the administrator would select a " Quarantine " action, which instructs FortiNAC-F to move the endpoint to a restricted VLAN or apply a restrictive ACL.

While " Methods " (A) relate to authentication and " Security Strings " (E) are used for specific SNMP or CLI matching, they are not the structural components of a Security Rule in the Security Incidents menu.

" Security Rules are used to perform a specific action based on certain criteria... To configure a Security Rule, navigate toLogs > Security Incidents > Rules. Each rule requires aTriggerto define the event criteria, anActionto define the automated response (such as Quarantine), and aUser/Host Profileto limit the rule to specific groups. " —FortiNAC-F Administration Guide: Security Rules and Incident Management.

TheUser/Host Profilein FortiNAC-F is the fundamental logic engine used to categorize endpoints for policy assignment. As seen in the exhibit, the configuration uses a combination of Boolean logic operators (ORandAND) to define the " Who/What " attributes.

According to theFortiNAC-F Administrator Guide, attributes grouped together within the same bracket or connected by anORoperator require only one of those conditions to be met. In the exhibit, the first two attributes are " Host Role = Contractor " OR " Host Persistent Agent = Yes " . This forms a single logical block. This block is then joined to the third attribute ( " Host Security Access Value = Contractor " ) by anANDoperator. Consequently, a host must satisfyat least oneof the first two conditionsANDsatisfy the third condition to match the " Who/What " section.

Furthermore, the profile includesLocationandWhen(time) constraints. The exhibit shows the location is restricted to the " Building 1 First Floor Ports " group. The " When " schedule is explicitly set toMon-Fri 6:00 AM - 5:00 PM. For a profile to match,allenabled sections (Who/What, Locations, and When) must be satisfied simultaneously. Therefore, the host must meet the conditional contractor/agent criteria, possess the specific security access value, and connect during the defined 6 AM to 5 PM window.

" User/Host Profiles use a combination of attributes to identify a match. Attributes joined byORrequire any one to be true, while attributes joined byANDmust all be true. If aSchedule(When) is applied, the host must also connect within the specified timeframe for the profile to be considered a match. All criteria in the Who/What, Where, and When sections are cumulative. " —FortiNAC-F Administration Guide: User/Host Profile Configuration.

In anN+1 High Availability (HA)configuration, a single secondary Control and Application (CA) server provides backup for multiple primary CA servers. The FortiNAC-F Manager (FortiNAC-M) acts as the centralized orchestrator for this cluster, monitoring the health of all participating nodes.

According to theFortiNAC-F 7.6.0 N+1 Failover Reference Manual, when a primary CA (such asCA-2in the exhibit) fails, the secondary CA (CA-3) is automatically promoted by the Manager to take over the specific workload and database functions of that failed primary. Crucially, the documentation specifies that even after this promotion, the system architecture maintains its N+1 logic. The secondary CA effectively " assumes the identity " of the failed primary while continuing to operate within the N+1 framework established by the Manager.

It doesnotmerge with CA-1 to form a traditional 1+1 active/passive cluster (A), nor does it engage in load balancing (D), as FortiNAC-F HA is designed for redundancy and failover rather than active traffic distribution. Furthermore, CA-3 does not " share " management with CA-1 (C); it independently handles the tasks originally assigned to CA-2. Throughout this failover state, the Manager continues to oversee the group, and CA-3 remains the designated secondary unit currently acting in a primary capacity for the downed node until CA-2 is restored.

" In an N+1 Failover Group, theSecondary CAis designed to take over the functionality ofany single failed primary componentwithin the group. The FortiNAC Manager monitors the primaries and initiates the failover to the secondary... Once failover occurs, the secondary continues to operate as the backup unit for the failed primary while remaining part of the managed N+1 HA configuration. " —FortiNAC-F 7.6.0 N+1 Failover Reference Manual: Failover Behavior Section.

The correct answer is A . In the exhibit, the Template Name is Engineer-Contractor , and the selected Role option is Use a unique Role based on this template name . That means FortiNAC-F uses the template name itself as the role value for any account created from this guest/contractor template. The study guide confirms this behavior: by default, the Role field is populated with the template name, although the administrator can alternatively select from an existing role list. It also states that the role value in the guest and contractor template populates the Role field of any account created from that template.

Option B , Eng-Contractor , is wrong because that value is entered in the Security and Access Value field, not the Role field. That value can still be used in user/host profiles or policies, but it does not populate the account Role field. Option C , Contractor , is only the Visitor Type , which controls the kind of guest/contractor account and associated icon behavior. Option D , Accounting Contractor , is visible in the disabled Select Role dropdown, but that option is not selected because the template is configured to use a unique role based on the template name.
