Fortinet NSE5_FNC_AD_7.6 Dumps

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.

In FortiNAC-F, theConference Manageris 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 theFortiNAC-F Administration GuideregardingAdministrative Profiles, when an administrator creates a profile for a Conference Manager, they can define specific "Account Limits." Under the profile settings (located inSystem > 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 thetypeof account (e.g., duration and access level), theAdministrative Profiledefines thecapabilities and limitationsof 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.

TheN+1 High Availability (HA)architecture was introduced in FortiNAC-F version 7.6 to provide a more scalable and flexible redundancy model compared to the traditional 1+1 active/passive setup. In an N+1 configuration, a single secondary (standby) appliance can provide coverage for multiple primary (active) Control and Application (CA) appliances.

To set up an N+1 HA cluster, there are two fundamental structural requirements:

A FortiNAC-F Manager (FortiNAC-M):Unlike standard 1+1 HA, which can be configured directly between two CAs, N+1 management is centralized. The FortiNAC-M acts as the orchestrator that manages the failover groups, monitors the health of the primaries, and coordinates the promotion of the secondary server if a primary fails.

A FortiNAC-F device designated as a Secondary:The cluster must have one appliance explicitly configured with theSecondary failover role. This device remains in a standby state, receiving database replications from all N primaries in its group until it is called upon to take over the functions of a failed unit.

While a cluster can support multiple primaries (D), it does not strictly require "at least two" to function as an N+1 group; it simply requires N primaries (where N ≥ 1). Additionally, N+1 is typically a Layer 3 managed solution via the Manager, meaning it does not mandate a "dedicated VLAN" for synchronization like some Layer 2 HA deployments.

"In FortiNAC-F 7.6,FortiNAC-Mfunctions as a manager to manage the N+1 Failover Groups... enabling N+M high availability for CAs. To create an N+1 Failover group, you should add thesecondary CAto the FortiNAC-M first, then add the primary CAs. The secondary CA is designed to take over the functionality of any single failed primary component." —FortiNAC-F 7.6.0 N+1 Failover Reference Manual.
