• Question 31:

  FortiGate has been added to FortiAIOps for management.

  

  Which step must be performed on FortiAIOps to add a FortiSwitch device connected to the recently added FortiGate?

  A. Add the FortiSwitch device by submitting its serial number.
  B. FortiAIOps requires that the FortiSwitch IP address is submitted.
  C. FortiSwitch is added automatically.
  D. Configure the FortiSwitch IP address, user ID, and password
  C. FortiSwitch is added automatically.

  ---

  In a LAN Edge deployment:

  FortiSwitch is managed through FortiGate via FortiLink .

  FortiAIOps integrates with FortiGate as the single managed device; from there it gains visibility into all Fabric and LAN-edge devices (FortiSwitch, FortiAP) that are registered to that FortiGate.

  Once the FortiGate is successfully added to FortiAIOps (as shown in the exhibit, statusOnline / Successfully Discovered ), all FortiSwitches managed by that FortiGate are:

  Discovered automatically through the FortiGate-FortiAIOps connection

  Shown under the appropriate inventory / switch views with no separate onboarding step for each switch.

  This is why no extra IP, serial number, or credential entry is required for FortiSwitch.

  So:

  Aand suggest manual per-switch onboarding, which is not how FortiAIOps works with LAN Edge.

  FortiGate, not the switch.

  Therefore the correct behavior is that the FortiSwitch is added automatically (C) once its managing FortiGate is connected to FortiAIOps.

• Question 32:

  Refer to the exhibits.

  

  \

  

  The exhibits show the VAP configuration. Wi-Fi SSIDs. and zone table.

  Which two statements describe how FortiGate handles VLAN assignment for wireless clients? (Choose two.)

  A. FortiGate will load balance clients using VLAN 101 and VLAN 102 and assign them an IP address from the 10.0.3.0/24 subnet.
  B. All clients connecting to the Corp Zone will receive an IP address from the 10.0.20.0/24 subnet.
  C. Clients connecting to APs in the Floor 1 group will not be able to receive an IP address.
  D. Clients connecting to APs in the Office group will be assigned to VLAN 102.
  C. Clients connecting to APs in the Floor 1 group will not be able to receive an IP address.
  D. Clients connecting to APs in the Office group will be assigned to VLAN 102.

  ---

  The VAP configuration clearly shows VLAN pooling using WTP-groups :

  set vlan-pooling wtp-group

  config vlan-pool

  edit 101

  set wtp-group "Floor_1"

  edit 102

  set wtp-group "Office"

  How VLAN assignment works in this mode

  VLAN-pooling with wtp-group modemeans:

  Each AP group (WTP group) is tied to exactly one VLAN in the pool.

  The FortiGate does not load balance VLANs.

  Instead, VLANs are mapped per AP group , not per client.

  Now verify each answer option:

  A. FortiGate will load balance clients using VLAN 101 and 102...

  #Incorrect.

  FortiGate does NOT load-balance clients when vlan-pooling is set to wtp-group .

  Each AP group receives only the VLAN mapped to it .

  B. All clients in the Corp zone get IPs from 10.0.20.0/24

  #Incorrect.

  In the Wi-Fi zone table, only Corp.102 has an IP subnet:

  Corp.101 # 0.0.0.0/0.0.0.0 (no IP assigned # clients get no DHCP)

  Corp.102 #10.0.20.1/255.255.255.0

  Thus, clients associated to VLAN 101 cannot get IPs.

  C. Clients connecting to APs in the Floor_1 group cannot receive an IP address

  #Correct.

  Reason:

  Floor_1 WTP-group # VLAN101

  VLAN 101 has no IP in the Wi-Fi table # 0.0.0.0/0.0.0.0

  No DHCP =Clients receive no IP address

  D. Clients connecting to APs in the Office group will be assigned to VLAN 102

  #Correct.

  Reason:

  Office WTP-group maps to VLAN102

  VLAN 102 has subnet10.0.20.0/24

  So Office group clients get an IP in that range

• Question 33:

  You are configuring FortiAuthenticator to integrate with FSSO for user identification. To enable FortiAuthenticator to extract user information from syslog messages and inject it into FSSO, you have configured syslog matching rules. What is the role of syslog matching rules in the process of injecting user information into FSSO?

  A. To automatically update user group memberships in FSSO based on syslog events
  B. To enforce user authentication policies based on syslog message contents
  C. To define how syslog messages are parsed and extract user information, such as usernames and IP addresses
  D. To filter and block irrelevant syslog messages from being processed by the FortiAuthenticator
  C. To define how syslog messages are parsed and extract user information, such as usernames and IP addresses

  ---

  When FortiAuthenticator is used as an FSSO agent based on syslog , it must:

  Parse incoming syslog messagesfrom devices (firewalls, WLAN controllers, VPN concentrators, etc.).

  Extract identity fieldssuch as:

  Username

  IP address

  Login/logout event indicators

  Syslog matching rules on FortiAuthenticator define:

  Which syslog messages are relevant (by facility, message pattern, or regex).

  How to capture specific fields (username, IP, group, event type).

  FortiAuthenticator then uses this parsed data to inject logon sessions into FSSO , so FortiGate can apply identity-based policies.

  Thus, the role of syslog matching rules is exactly as described in C

  A: Group mapping is handled separately via directory groups / FSSO config, not directly by matching rules.

  B: Enforcement of authentication policies is done on FortiGate, not directly by the matching rules.

  D: While irrelevant logs can be ignored via rules, the primary purpose is parsing and extraction , not generic filtering.

• Question 34:

  When troubleshooting a captive portal issue, which POST parameter in the redirected HTTPS request can be used to track the user's session and ensure that the request is valid?

  A. username
  B. redir
  C. magic
  D. email
  C. magic

  ---

  In FortiGate captive portal workflows (local or external):

  Client connects to SSID / interface that has captive portal enabled.

  Client makes an HTTP/HTTPS request.

  FortiGate intercepts and redirects to a login page (local or external URL).

  The portal form is submitted via POST back to FortiGate.

  To prevent tampering and to tie the POST back to the correct user session , FortiGate includes a special hidden parameter in the redirect and expects it in the POST:

  The parameter is named magic .

  The magic value:

  Is a unique token generated per captive-portal session.

  Encodes/session-links the user's IP, interface, and session info.

  Allows FortiGate to ensure that:

  The POST comes from the user who initiated the original request.

  The request is not a random or replayed submission.

  When troubleshooting:

  If the external portal does not preserve and resend the magic parameter back to FortiGate exactly as received, authentication fails, and you'll see errors like "session not found" or "invalid magic".

  Why the other fields are not used for this purpose

  A. username - Just the login ID; multiple users can use the same username from different locations, so it can't uniquely track the browser session.

  B. redir - Contains the URL the user originally requested, so they can be sent back there after login. It is not a session integrity token.

  D. email - Optional field used in some guest/registration flows; irrelevant to session validation.

• Question 35:

  Refer to the exhibit.

  

  On FortiGate, a RADIUS server is configured to forward authentication requests to FortiAuthenticator, which acts as a RADIUS proxy. FortiAuthenticator then relays these authentication requests to a remote Windows AD server using LDAP.

  While testing authentication using the CLI command diagnose test authserver. the administrator observed that authentication succeeded with PAP but failed when using MS-CHAFV2. Which two solutions can the administrator implement to enable MS-CHAPv2 authentication? (Choose two.)

  A. Change the FortiGate authentication method to CHAP instead of MS-CHAPv2.
  B. Enable Windows Active Directory domain authentication on FortiAuthenticator.
  C. Enable RADIUS attribute filtering on FortiAuthenticator.
  D. Configure FortiAuthenticator to use RADIUS instead of LDAP as the back-end authentication server
  A. Change the FortiGate authentication method to CHAP instead of MS-CHAPv2.
  D. Configure FortiAuthenticator to use RADIUS instead of LDAP as the back-end authentication server

• Question 36:

  APs have been manually configured to connect to FortiGate over an IPsec network, and FortiGate successfully detects and authorizes them. However, the APs remain unmanaged because FortiGate is unable to establish a CAPWAP tunnel with them. What configuration change can resolve this issue and enable FortiGate to establish the CAPWAP tunnel over the IPsec connection?

  A. Configure a static route on FortiGate to reach the APs over the IPsec tunnel.
  B. Assign a custom AP profile for the remote APs with the set mpls-connection option enabled.
  C. Decrease the CAPWAP tunnel MTU size for APs to prevent fragmentation.
  D. Upgrade the FortiAP firmware image to ensure compatibility with the FortiOS version.
  B. Assign a custom AP profile for the remote APs with the set mpls-connection option enabled.

  ---

  When FortiAPs connect to FortiGate over IPsec tunnels , this is treated similarly to WAN/MPLS deployments.

  In these scenarios, FortiGate must know that CAPWAP must traverse a non-L2 transport.

  FortiAP profiles include:

  set mpls-connection enable

  This setting is required so that:

  FortiGate can encapsulate CAPWAP inside the transport tunnel

  Remote FortiAPs can establish CAPWAP even when behind routed/IPsec networks

  Without this option, the FortiGate detects the AP but cannot bring CAPWAP UP , leaving the AP in "discovered/unauthorized" or "offline" state.

  Why others are wrong

  A. Static route# Discovery already succeeds, so routing is not the issue.

  C. Reduce MTU# Sometimes useful for IPsec, but not required for CAPWAP establishment.

  D. Firmware upgrade# Firmware mismatch would show "Managed (upgrade required)," not CAPWAP tunnel failure. Therefore, set mpls-connection enable is the required fix.

• Question 37:

  Which statement about generating a certificate signing request (CSR) for a CER certificate is true?

  A. Inaccurate or missing fields in the CSR will prevent the CA from validating the request, leading to the rejection of the certificate and possible delays in the deployment process.
  B. If key fields like the common name (CN) and organization (O) are incorrect, the certification authority (CA) will still issue the certificate, but it may not be trusted by certain applications or systems that rely on accurate field information for validation.
  C. CSR fields are primarily used for internal recordkeeping by the requesting organization, and only the public key in the CSR must be accurate for successful certificate signing.
  D. The fields in the CSR are primarily for documentation purposes; any missing or incorrect information will be automatically corrected by the CA during the signing process.
  A. Inaccurate or missing fields in the CSR will prevent the CA from validating the request, leading to the rejection of the certificate and possible delays in the deployment process.

  ---

  The FortiOS documentation explicitly states that a CSR used for certificate signing must contain accurate and valid fields, especially:

  Common Name (CN)

  Organization (O)

  Country (C)

  Public key parameters

  According to the FortiGate certificate section:

  Incorrect CSR field information can cause the CA to reject the request.

  Reasons include:

  The CA validates identity and organizational information.

  Missing or malformed data invalidates PKI requirements.

  The CSR is not corrected automatically by the CA.

  Therefore:

  #A is correct.

  Options B-D contradict PKI principles:

  B is false: CAs do not issue certificates with mismatched identity fields for public trust.

  C is false: CSR fields are not only for internal use; they define certificate identity.

  D is false: CAs do not auto-correct CSR fields.

• Question 38:

  Your office wants to set up a Wi-Fi network for visitors. Your company would like to require them to log in for (racking purposes. Which two types of captive portals could be enabled on an interface? (Choose two.)

  A. Terms Acknowledgment Without Authentication
  B. Email Notification Only
  C. Disclaimer + Authentication
  D. Guest Pass Access
  E. Authentication
  A. Terms Acknowledgment Without Authentication
  E. Authentication

  ---

  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 on FortiAuthenticator , not as a direct portal type on FortiGate.

• Question 39:

  Refer to the exhibits.

  

  A set of SSID profiles has been configured on FortiManager, and an AP profile has been assigned to a group of AP managed by FortiGate. However, none of the designated SSIDs are being broadcast by these APs. Which configuration change is required to make the APs broadcast these SSIDs as intended?

  A. Adjust the AP profile to ensure all SSIDs are configured in a supported mode, either bridge or tunnel, but not a mix of both.
  B. Change the AP profile to use a platform that supports the configured mix of SSIDs.
  C. Choose Manual in the SSIDs setting and select the SSIDs to broadcast.
  D. Set the Transmit Power Mode to Auto.
  C. Choose Manual in the SSIDs setting and select the SSIDs to broadcast.

  ---

  From the exhibits:

  The AP profile shows:

  SSIDs: Tunnel | Bridge | Manual

  The current setting is Bridge , not Manual.

  When Bridge Tunnel or is selected, the AP profile does NOT automatically broadcast SSIDs unless 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 to Manual , 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.

• Question 40:

  What is the primary function of FortiLink NAC in a LAN environment?

  A. To extend security policies across FortiGate firewalls only
  B. To automate device onboarding and verify security posture
  C. To manage FortiSwitch devices and apply manual firewall rules
  D. To ensure devices are manually placed in VLANs based on their user roles
  B. To automate device onboarding and verify security posture

  ---

  FortiLink NACis the NAC (Network Access Control) engine built into FortiGate when it manages FortiSwitch devices.

  It performs:

  #Automated device onboarding

  Automatically detects new devices connecting to switches.

  Uses MAC, vendor, DHCP fingerprinting, or IoT database to classify devices.

  No manual VLAN assignment required.

  #Security posture verification

  Works with FortiClient EMS, ZTNA tags, IoT detection.

  Applies policies based on:

  Device type

  User role

  Endpoint compliance

  IoT vulnerability status

  #Dynamic VLAN assignment

  Automatically moves devices into proper VLANs, quarantine networks, or guest zones.

  #Integration with LAN Edge and Zero Trust

  Uses FortiGate + FortiSwitch + FortiAP to enforce zero-trust access.

  This matches the LAN Edge 7.6 Architect explanation of FortiLink NAC.

  #Why other answers are wrong

  A. Extend security policies across FortiGate firewalls

  Not NAC. That refers to Security Fabric or SD-WAN.

  C. Apply manual firewall rules

  FortiLink NAC is specifically designed to automate access control.

  D. Manually place devices in VLANs

  NAC eliminates manual VLAN assignment -- it is dynamic.
