Fortinet NSE5_FNC_AD_7.6 Exam With Confidence Using Practice Dumps

In FortiNAC-F, theInventory topologyuses specific icons to represent the status and model of discovered network infrastructure. When a switch or other network device is discovered via SNMP, FortiNAC-F retrieves itsSystem ObjectID (sysObjectID)to identify the specific make and model. This OID is then compared against the internal database of supported device mappings.

Aquestion mark (?)icon appearing on a discovered switch indicates that while the discovery process successfully communicated with the device (meaning SNMP credentials were correct), theSNMP ObjectID is not recognizedor mapped in the current version of FortiNAC-F. This essentially means the device is " unsupported " by the current software out-of-the-box. Because the OID is unknown, FortiNAC-F does not know which CLI or SNMP command set to use for critical functions like L2 polling (host visibility) or VLAN switching (enforcement). To resolve this, an administrator can manually " Set Device Mapping " to a similar existing model or a " Generic SNMP Device " if only basic L3 visibility is required.

" Discovered devices displaying a ' ? ' iconindicate the currently running version does not have a mapping for that device ' sSystem OID(device is not supported). Device mappings are used to manage the device by performing functions such as L2/L3 Polling, Reading, and Switching VLANs.

The correct answer is D . The log output shows the local IP address as 192.168.10.10 , which the question identifies as the primary FortiNAC-F server. In the same output, FortiNAC-F reports inControl true and controlServer true , which means the local primary server is currently the control server. The line showing communication to 192.168.10.110 returns Running - Not In Control , confirming that the secondary server is alive but is not the active controlling node.

This matches FortiNAC-F 1+1 HA behavior. The study guide describes a 1+1 HA pair as an active-passive deployment where one FortiNAC-F device is designated primary and the other secondary. Database and configuration synchronization keep the devices aligned, but only one server is in control at a time. If the primary fails, the secondary assumes control automatically; otherwise, the primary remains the active control server.

Option A is wrong because the secondary explicitly reports Not In Control . Option B is wrong because the output does not show database replication failure. Option C is wrong because failover is not in progress; the output shows a stable state where the primary is in control and the secondary is running as the passive node.

In a1+1 High Availability (HA)deployment, FortiNAC-F supports two primary methods for management access: individual IP addresses or aShared IP Address(also known as a Virtual IP or VIP). The Shared IP option is part of aLayer 2 HAdesign, which simplifies administration by providing a single URL or IP that always points to whichever appliance is currently in the " Active " or " In Control " state.

For a Shared IP configuration to function correctly, thePrimary and Secondary administrative interfaces (port1) must be on the same subnet. This requirement exists because the Shared IP is a logical address that is dynamically assigned to the physical interface of the active unit. Since only one unit can own the IP at a time, both units must reside on the same broadcast domain (Layer 2) to ensure that ARP requests for the Shared IP are correctly answered and that the gateway remains reachable regardless of which unit is active. If the appliances were on different subnets (a Layer 3 HA design), a shared IP could not be used because it cannot " float " across different network segments; instead, administrators would need to manage each unit via its unique physical IP or use a FortiNAC Manager.

" For L2 HA configurations, click theUse Shared IP Addresscheckbox and enter the Shared IP Address information...If your Primary and Secondary Servers are not in the same subnet, do not use a shared IP address.The shared IP address moves between appliances during a failover and recovery and requires both units to reside on the same network.
