Fortinet FCSS_LED_AR-7.6 Exam Dumps

From the exhibits:

Interface''APs''is a VLAN sub-interface onfortilinkwith IP10.10.100.254/24and a DHCP server scope 10.10.100.1--10.10.100.253.

This VLAN is assigned toport1on the managed FortiSwitch for FortiAPs.

The interface config showsonly allowaccess ping---Security Fabric Connection is not enabled.

In LAN Edge designs, FortiAPs connected through FortiSwitch are discovered and managed asLAN edge devices of the Security Fabric. FortiOS documentation states that FortiAPs and FortiSwitches appear in the Fabric topologyonly when connected on an interface with Security Fabric Connection enabled.

If the VLAN/AP management interface lacksSecurity Fabric Connection:

FortiGate does not treat that network as aFabric connection segment.

CAPWAP discovery from FortiAPs on that VLAN will not result in the AP being onboarded and shown for management.

Therefore the key misconfiguration is:

A -- Security Fabric is disabled on the VLAN interface used for AP management.

Why the others are not the root cause:

B . Firmware incompatibility-- would usually show as a ''Managed (upgrade required)'' or similar status after discovery, not complete non-detection. The scenario specifically points to a configuration issue, not firmware.

C . VLAN not tagged correctly on uplink-- The FortiSwitch uplink to FortiGate is the FortiLink trunk, and the VLAN sub-interface APs is already bound to fortilink, so tagging on the uplink is correct by definition.

D . CAPWAP ports not open-- CAPWAP (UDP 5246/5247) is terminated locally on FortiGate and does not depend on any firewall policy; these ports are open on the FortiGate itself by default.

Context: You're troubleshootingSyslog-based SSOonFortiAuthenticator:

Devices (typically firewalls, WLAN controllers, VPN gateways) sendsyslog messagescontaining usernames, IPs, login/logout events.

FortiAuthenticator parses those logs usingSyslog SSO rulesand injects logon sessions intoFSSOfor FortiGate.

When users are not mapping correctly, you need to see:

Did the syslog message arrive?

Which matching rule (if any) caught it?

What username and IP were extracted?

Why was a message ignored or rejected?

FortiAuthenticator has a dedicated debug area for this:

Debug logs Single Sign-On Syslog SSO

This view shows:

Raw syslog lines received

Thematching ruleapplied (or ''no match'')

Parsed fields (username, IP, group)

Any parsing errors

This is exactly the tool designed totroubleshoot and diagnose Syslog SSO issues.

Why the other options are not the best for this issue

A . Debug logs > Remote Servers > Syslog Viewer

Lets you see syslog traffic in general, but doesnotshow how SSO rules are applied or why they fail. Good for connectivity checks, not SSO logic.

B . Parsing Test Tool

Useful totestpatterns and rules manually by pasting sample log lines, but it doesn't show live traffic or running SSO sessions.

C . Debug logs > SSO Sessions page

Shows existing SSO sessions (who is logged in), but notwhya particular syslog message did not create a session.

A FortiGate interface can operate with different types of captive portal modes.

The available portal types that require user interaction or login include:

A. Terms Acknowledgment Without Authentication

Forces users to accept terms before accessing the network

No credentials required

Still considered a captive portalCommon in guest Wi-Fi.

E. Authentication

Requires username/password

Supports local users, RADIUS, LDAP, OAuth, etc.

Why the other options are incorrect

B. Email Notification Only

Not a valid captive portal mode on FortiGate.

C. Disclaimer + Authentication

This is not a selectable mode; disclaimers are part of the captive portal customization but not a standalone option.

D. Guest Pass Access

Guest pass authentication exists onFortiAuthenticator, not as a direct portal type on FortiGate.

From the exhibits:

The AP profile shows:

SSIDs: Tunnel | Bridge | Manual

The current setting isBridge, not Manual.

WhenBridgeorTunnelis selected, the AP profiledoes NOT automatically broadcast SSIDsunless the corresponding VAPs were explicitly mapped in the AP profile.

FortiManager SSID profiles are created, but unless these are explicitly applied underManual SSIDs selection, the AP will not broadcast any SSID.

Fortinet documentation states:

''To control which SSIDs an AP broadcasts, the AP Profile must have SSIDs set toManual, and the desired SSIDs must be selected.''

Therefore, to make the AP broadcast the intended SSIDs:

You must switch the SSIDs setting to Manual, and manually select the SSIDs (CompanyPrinters, Student01, Guest-CorpPort, PSK).

Why the other options are incorrect:

A . Adjust AP profile to avoid mixing bridge/tunnelMixed modes ARE supported. Not the issue.

B . Change platformThe platform (FAP231F) already supports all listed SSIDs.

D . Set transmit power mode to autoPower settings have nothing to do with SSID broadcasting.

From the exhibits:

FortiSwitch Ports viewshows:

port2

Mode: Static

Native VLAN: Students

Allowed VLANs: quarantine.fortilink (quarantine)

NAC policy ''Training'':

Switch FortiLink: fortilink

Category:Device

Matching criteria:

MAC Address: 70:88:6b:8c:4b:0e (enabled)

Operating System:Linux(enabled)

Switch Controller Action:

Assign VLAN = Students

Bounce Port = enabled

Design intent:

Device with that MAC + OS Linux, when plugged intoport2, should be dynamically moved to VLANStudentsby the NAC policy.

Why it doesn't work now

On FortiLink NAC,dynamic NAC decisions only apply on ports whose ''Access Mode'' is set to NAC:

NAC mode = FortiGate controls theonboarding VLAN, evaluates NAC policies, and then dynamically reassigns the switch port VLAN (access, quarantine, etc.).

Static mode(what we see on port2) means the port just uses its configurednative/allowed VLANs, andno NAC classificationhappens.

Right now:

port2 is astatic access portwith Native VLAN = Students.

The NAC policy exists, butFortiSwitch is not in NAC enforcement mode on that port, so the policy is never evaluated for traffic on port2.

Therefore, themissing configurationis:

Setport2toNAC mode(sometimes called ''Access mode: NAC'' or ''NAC LAN edge port'').

Once port2 is changed to NAC mode:

Device initially lands in the onboarding/quarantine VLAN.

FortiGate collects device info (MAC, OS, etc.).

NAC policy ''Training'' matches MAC + Linux.

Switch controller actionAssign VLAN = Studentsis applied.

Port is bounced (if configured), bringing the device back up in VLAN Students.

Why the other options are wrong

B . MAC or OS misconfigured

Possible in general, but the question asks forwhich configuration is missing, and the exhibits clearly focus on port mode. Also, even with wrong MAC/OS, the port would still be in NAC mode; here NAC isn't even active.

C . Port Policy mode

Port policy (edge/trunk) is separate from NAC; NAC requires the specificNAC access mode.

D . Students VLAN should be Allowed VLANs instead of Native VLAN

For an access port, having Students as thenative VLANis correct. NAC policy's Assign VLAN will set that as access VLAN; no need to make it an allowed trunk VLAN.
