NEW QUESTION # 55
What is the default RSSO attribute FortiAuthenticator uses to group users?
Response:
- A. Class
- B. Group-ID
- C. Filter-ID
- D. CN
Answer: C
NEW QUESTION # 56
In a Windows environment using AD machine authentication, how does FortiAuthenticator ensure that a previously authenticated device is maintaining its network access once the device resumes operating after sleep or hibernation?
- A. It temporarily assigns the device to a guest VLAN until full reauthentication is completed.
- B. It uses machine authentication based on the device IP address.
- C. It caches the MAC address of authenticated devices for a configurable period of time.
- D. It sends a wake-on-LAN packet to trigger reauthentication.
Answer: C
Explanation:
WithAD machine authenticationvia FortiAuthenticator:
* When a machine successfully authenticates, FortiAuthenticator records:
* Machine account / identity
* MAC addressof the device
* Associated IP and session info
To handle sleep/hibernation:
* FortiAuthenticator keeps acache of authenticated MAC addressesfor a configured timeout.
* When the device wakes up and sends traffic again, FortiAuthenticator/FSSO can still treat it as authenticated as long as its MAC is in cache, so access is maintained without forcing a full machine re- auth immediately.
This matches optionD.
* A(guest VLAN) is not the standard behavior here.
* B(WoL) is unrelated.
* C(IP-based) would break as IPs can change; MAC-based caching is what's used.
NEW QUESTION # 57
Which Fortinet technologies can dynamically assign VLANs based on user or device attributes?
(Choose two)
Response:
- A. FortiAuthenticator
- B. FortiCloud
- C. FortiAnalyzer
- D. FortiLink NAC
Answer: A,D
NEW QUESTION # 58
Refer to the exhibit.
A RADIUS server has been successfully configured on FortiGate, which sends RADIUS authentication requests to FortiAuthenticator. FortiAuthenticator, in turn, relays the authentication using LDAP to a Windows Active Directory server.
It was reported that wireless users are unable to authenticate successfully.
The FortiGate configuration confirms that it can connect to the RADIUS server without issues.
While testing authentication on FortiGate using the command diagnose test authserver radius, it was observed that authentication succeeds with PAP but fails with MSCHAPv2.
Additionally, the Remote LDAP Server configuration on FortiAuthenticator was reviewed.
Which configuration change might resolve this issue?
- A. Enable Windows Active Directory Domain Authentication.
- B. Use RADIUS attributes under the FortiGate configuration.
- C. Manually add user credentials to the FortiAuthenticator local database
- D. Change the RADIUS authentication protocol to CHAP
Answer: A
Explanation:
From the exhibits and text:
* FortiGate #RADIUS# FortiAuthenticator
* FortiAuthenticator #LDAP# Windows AD
* diagnose test authserver radius ... papsucceeds
* diagnose test authserver radius ... mschap2fails
This behavior matches a classic limitation documented in FortiOS:
When usingLDAPas the back-end, the RADIUS server must usePAP. CHAP/MS-CHAPv2 arenot supported with plain LDAP because the server cannot validate the challenge-response without access to password hashes.
In the Remote LDAP server config on FortiAuthenticator, the option"Windows Active Directory Domain Authentication" is disabled.When this feature isenabled, FortiAuthenticator can talk to AD usingKerberos
/NTLMinstead of a simple LDAP bind, whichdoes support MS-CHAPv2for incoming RADIUS authentications.
So to allow MS-CHAPv2 all the way from FortiGate to AD, you must:
* Keep FortiGate using RADIUS with MS-CHAPv2 # FortiAuthenticator
* EnableWindows Active Directory Domain Authenticationso FortiAuthenticator can properly validate MS-CHAPv2 against AD.
Why the other options are wrong:
* A. Change to CHAP- CHAP still cannot be validated over LDAP; docs say LDAP back-ends must use PAP.
* C. Manually add users to local DB- That would allow local-DB auth but does not fix MS-CHAPv2 against AD.
* D. Use RADIUS attributes on FortiGate- Attributes do not influence the EAP inner method; they don't fix MS-CHAPv2 failures.
Therefore the configuration change that can realistically fix the MS-CHAPv2 problem isenabling Windows Active Directory Domain Authentication on FortiAuthenticator (B).

- E. Set up the FortiAuthenticator internal database as the primary source for user credentials
Answer: D,E
NEW QUESTION # 63
Refer to the exhibits.
FortiGate RSSO configuration
FortiGate RSSO Group
FortiGate interface configuration
RSSO authentication has been configured on FortiGate. Port3 has been enabled to receive RADIUS accounting messages. Internet access is available through port1. FortiGate is successfully handling incoming RADIUS accounting messages, ensuring that RSSO users are correctly mapped to the RSSO Group user group. The administrator realized that internet access is open to all users and aims to enforce access restrictions, ensuring that only RSSO users are permitted to have internet access. Which configuration change should the administrator apply to address this issue? Response:
- A. Modify the firewall policy and add RSSO Group as a Source.
- B. Change the RADIUS attribute value setting to match the name of the RADIUS attribute containing the group membership information of the RSSO users.
- C. Create a second firewall policy from port3 to port1, and select the target destination subnets.
- D. Configure a local user group and manually add users to enforce authentication-based restrictions.
Answer: A
NEW QUESTION # 64
Which VLAN is used by FortiGate to place devices that fail to match any configured NAC policies? CRSPAN
- A. Quarantine
- B. Onboarding
- C. NAC
- D. segment
Answer: B
Explanation:
In FortiLink NAC for LAN Edge:
* When a device first connects, it is placed into theonboarding VLAN.
* NAC policies then classify the device (by MAC, OS, user, EMS tag, etc.).
* If a NAC policy matches, the device may be moved to anaccess VLANorquarantine VLAN.
* Ifno NAC policy matches, the device simplystays in the onboarding VLAN.
FortiOS / LAN Edge documentation describes the onboarding VLAN as thedefault VLAN for unknown or unclassified devices, until NAC policy evaluation moves them elsewhere.
NEW QUESTION # 65
Which actions can FortiGate take when it places a device in quarantine?

Response:
- A. WPA3 and TLS
- B. DTLS and IPsec
- C. SSL/TLS and IPsec
- D. SSH and SSL
Answer: B
NEW QUESTION # 68
Refer to the exhibits.
You are adding a new FortiSwitch to FortiGate for management. All necessary settings have been configured on FortiGate, but FortiSwitch remains offline. The cabling has been verified and is correctly connected.
Which misconfiguration might be preventing FortiGate from detecting FortiSwitch?
- A. The Fortilink interface has the wrong interface member.
- B. The Fortilink interface setting ip-managed-by-fortiipam must be enabled.
- C. The DHCP server setting vci-string is misconfigured.
- D. The Fortilink interface setting cype must be physical.
Answer: C
Explanation:
On FortiLink, FortiGate's built-in DHCP server is what gives FortiSwitch its IP so it can come under management. For automatic FortiSwitch onboarding, the DHCP server is usually set with:
set vci-match enable
set vci-string "FortiSwitch" "FortiExtender"
In the exhibit, the DHCP server for fortilink has:
set vci-match enable
set vci-string "FortiExtender"
Because theVCI string doesn't include "FortiSwitch", DHCP offers are only sent to clients whose Vendor Class Identifier matchesFortiExtender. The FortiSwitch never receives an IP, so it staysOffline.
* OptionBis wrong: member "port4" matches the physical cabling in the topology.
* OptionCis fine: FortiLink can be anaggregateinterface, not only physical.
* OptionA(ip-managed-by-fortiipam) is unrelated; FortiIPAM isn't required here.
NEW QUESTION # 69
