Refer to the exhibit

Examine the FortiGate RSSO configuration shown in the exhibit
FortiGate is configured to receive RADIUS accounting messages on port3 to authenticate RSSO users The users are located behind port3 and the internet link is connected to port1 FortiGate is processing incoming RADIUS accounting messages successfully and RSSO users are getting associated with the RSSO Group user group However all the users are able to access the internet, and the administrator wants to restrict internet access to RSSO users only Which configuration change should the administrator make to fix the problem?

• A. Add RSSO Group to the firewall policy
• B. Create a second firewall policy from port3 lo port1 and select the target destination subnets
• C. Enable Security Fabric Connection on port3
• D. Change the RADIUS Attribute Value selling to match the name of the RADIUS attribute containing the group membership information of the RSSO users

正解：A

解説：
Explanation
According to the exhibit, the firewall policy from port3 to port1 has no user group specified, which means that it allows all users to access the internet. Therefore, option B is true because adding RSSO Group to the firewall policy will restrict internet access to RSSO users only. Option A is false because changing the RADIUS Attribute Value setting will not affect the firewall policy, but rather the RSSO user group membership. Option C is false because enabling Security Fabric Connection on port3 will not affect the firewall policy, but rather the communication between FortiGate and other Security Fabric devices. Option D is false because creating a second firewall policy from port3 to port1 will not affect the existing firewall policy, but rather create a redundant or conflicting policy.

質問 # 17
Which EAP method requires the use of a digital certificate on both the server end and the client end?

• A. EAP-GTC
• B. EAP-TTLS
• C. EAP-TLS
• D. PEAP

正解：C

解説：
Explanation
According to the FortiGate Administration Guide, "EAP-TLS is the most secure EAP method. It requires a digital certificate on both the server end and the client end. The server and client authenticate each other using their certificates." Therefore, option D is true because it describes the EAP method that requires the use of a digital certificate on both the server end and the client end. Option A is false because EAP-TTLS only requires a digital certificate on the server end, not the client end. Option B is false because PEAP also only requires a digital certificate on the server end, not the client end. Option C is false because EAP-GTC does not require a digital certificate on either the server end or the client end.

質問 # 18
An administrator is testing the connectivity for a new VLAN The devices in the VLAN are connected to a FortiSwitch device that is managed by FortiGate Quarantine is disabled on FortiGate While testing the administrator noticed that devices can ping FortiGate and FortiGate can ping the devices The administrator also noticed that inter-VLAN communication works However intra-VLAN communication does not work Which scenario is likely to cause this issue?

• A. The FortiGate ARP table is missing entries
• B. The native VLAN configured on the ports is incorrect
• C. The FortiSwitch MAC address table is missing entries
• D. Access VLAN is enabled on the VLAN

正解：C

解説：
Explanation
According to the scenario, the devices in the VLAN are connected to a FortiSwitch device that is managed by FortiGate. Quarantine is disabled on FortiGate, which means that the devices are not blocked by any security policy. The devices can ping FortiGate and FortiGate can ping the devices, which means that the IP connectivity is working. Inter-VLAN communication works, which means that the routing between VLANs is working. However, intra-VLAN communication does not work, which means that the switching within the VLAN is not working. Therefore, option C is true because the FortiSwitch MAC address table is missing entries, which means that the FortiSwitch does not know how to forward frames to the destination MAC addresses within the VLAN. Option A is false because access VLAN is enabled on the VLAN, which means that the VLAN ID is added to the frames on ingress and removed on egress. This does not affect intra-VLAN communication. Option B is false because the native VLAN configured on the ports is incorrect, which means that the frames on the native VLAN are not tagged with a VLAN ID. This does not affect intra-VLAN communication. Option D is false because the FortiGate ARP table is missing entries, which means that FortiGate does not know how to map IP addresses to MAC addresses. This does not affect intra-VLAN communication.

質問 # 19
Refer to the exhibit.

Examine the network diagram and packet capture shown in the exhibit
The packet capture was taken between FortiGate and FortiAuthenticator and shows a RADIUS Access-Request packet sent by FortiSwitch to FortiAuthenticator through FortiGate Why does the User-Name attribute in the RADIUS Access-Request packet contain the client MAC address?

• A. FortiSwitch is sending a RADIUS accounting message to FortiAuthenticator
• B. The client is performing user authentication
• C. The client is performing AD machine authentication
• D. FortiSwitch is authenticating the client using MAC authentication bypass

正解：D

解説：
Explanation
According to the exhibit, the User-Name attribute in the RADIUS Access-Request packet contains the client MAC address of 00:0c:29:6a:2b:3d. This indicates that FortiSwitch is authenticating the client using MAC authentication bypass (MAB), which is a method of authenticating devices that do not support 802.1X by using their MAC address as the username and password. Therefore, option B is true because it explains why the User-Name attribute contains the client MAC address. Option A is false because AD machine authentication uses a computer account name and password, not a MAC address. Option C is false because user authentication uses a user name and password, not a MAC address. Option D is false because FortiSwitch is sending a RADIUS Access-Request message to FortiAuthenticator, not a RADIUS accounting message.

質問 # 20
Refer to the exhibit.

Examine the FortiGate configuration FortiAnalyzer logs and FortiGate widget shown in the exhibit An administrator is testing the Security Fabric quarantine automation The administrator added FortiAnalyzer to the Security Fabric and configured an automation stitch to automatically quarantine compromised devices The test device (::.:.:.!) s connected to a managed Fort Switch dev :e After trying to access a malicious website from the test device, the administrator verifies that FortiAnalyzer has a log (or the test connection However the device is not getting quarantined by FortiGate as shown in the quarantine widget Which two scenarios are likely to cause this issue? (Choose two)

• A. FortiAnalyzer does not have a valid threat detection services license
• B. The web filtering rating service is not working
• C. FortiAnalyzer does not consider the malicious website an indicator of compromise (IOC)
• D. The device does not have FortiClient installed

正解：A、C

解説：
Explanation
According to the exhibits, the administrator has configured an automation stitch to automatically quarantine compromised devices based on FortiAnalyzer's threat detection services. However, according to the FortiAnalyzer logs, the test device is not detected as compromised by FortiAnalyzer, even though it tried to access a malicious website. Therefore, option B is true because FortiAnalyzer does not have a valid threat detection services license, which is required to enable the threat detection services feature. Option D is also true because FortiAnalyzer does not consider the malicious website an indicator of compromise (IOC), which is a criterion for identifying compromised devices. Option A is false because the web filtering rating service is working, as shown by the log entry that indicates that the test device accessed a URL with a category of
"Malicious Websites". Option C is false because the device does not need to have FortiClient installed to be quarantined by FortiGate, as long as it is connected to a managed FortiSwitch device.

質問 # 21
What is the purpose of enabling Windows Active Directory Domain Authentication on FortiAuthenticator?

• A. It enables FortiAuthenticator to import users from Windows AD
• B. It enables FortiAuthenticator to use a Windows CA certificate when authenticating RADIUS users
• C. It enables FortiAuthenticator to register itself as a Windows trusted device to proxy authentication using Kerberos
• D. It enables FortiAuthenticator to use Windows administrator credentials to perform an LDAP lookup for a user search

正解：C

解説：
Explanation
According to the FortiAuthenticator Administration Guide2, "Windows Active Directory domain authentication enables FortiAuthenticator to join a Windows Active Directory domain as a machine entity and proxy authentication requests using Kerberos." Therefore, option D is true because it describes the purpose of enabling Windows Active Directory domain authentication on FortiAuthenticator. Option A is false because FortiAuthenticator does not need Windows administrator credentials to perform an LDAP lookup for a user search. Option B is false because FortiAuthenticator does not use a Windows CA certificate when authenticating RADIUS users, but rather its own CA certificate. Option C is false because FortiAuthenticator does not import users from Windows AD, but rather synchronizes them using LDAP or FSSO.

質問 # 22
Which two statements about MAC address quarantine by redirect mode are true? (Choose two)

• A. The quarantined device is moved to the quarantine VLAN
• B. The device MACaddress is added to the Quarantined Devices firewall address group
• C. It is the default mode for MAC address quarantine
• D. The quarantined device is kept in the current VLAN

正解：B、D

解説：
Explanation
According to the FortiGate Administration Guide, "MAC address quarantine by redirect mode allows you to quarantine devices by adding their MAC addresses to a firewall address group called Quarantined Devices.
The quarantined devices are kept in their current VLANs, but their traffic is redirected to a quarantine portal." Therefore, options B and D are true because they describe the statements about MAC address quarantine by redirect mode. Option A is false because the quarantined device is not moved to the quarantine VLAN, but rather kept in the current VLAN. Option C is false because redirect mode is not the default mode for MAC address quarantine, but rather an alternative mode that can be enabled by setting mac-quarantine-mode to redirect.

Examine the FortiGate user group configuration and the Windows AD LDAP group membership information shown in the exhibit FortiGate is configured to authenticate SSL VPN users against Windows AD using LDAP The administrator configured the SSL VPN user group for SSL VPN users However the administrator noticed that both the student and j smith users can connect to SSL VPN Which change can the administrator make on FortiGate to restrict the SSL VPN service to the student user only?

• A. In the SSL VPN user group configuration set Group Nam to CN-SSLVPN, CN="users, DC-trainingAD, DC-training, DC-lab
• B. In the SSL VPN user group configuration set Group Name to ::;=Domain users.CN-Users/DC=trainingAD, DC-training, DC=lab.
• C. In the SSL VPN user group configuration change Type to Fortinet Single Sign-On (FSSO)
• D. In the SSL VPN user group configuration, change Name to cn=sslvpn, CN=users, DC=trainingAD, Detraining, DC-lab.

正解：A

解説：
Explanation
According to the FortiGate Administration Guide, "The Group Name is the name of the LDAP group that you want to use for authentication. The name must match exactly the name of the LDAP group on the LDAP server." Therefore, option A is true because it will set the Group Name to match the LDAP group that contains only the student user. Option B is false because changing the Name will not affect the authentication process, as it is only a local identifier for the user group on FortiGate. Option C is false because setting the Group Name to Domain Users will include all users in the domain, not just the student user. Option D is false because changing the Type to FSSO will require a different configuration method and will not solve the problem.

• A. The guest portal provides pre and post-log in services
• B. Administrators can use one or more incoming parameters to configure a mapping rule for the guest portal
• C. Each remote user on FortiAuthenticator can sponsor up to 10 guest accounts
• D. Administrators must approve all guest accounts before they can be used

正解：A、B

解説：
Explanation
According to the FortiAuthenticator Administration Guide2, "The guest portal provides pre and post-log in services for users (such as password reset and token registration abilities), and rules and replacement messages can be configured." Therefore, option C is true. The same guide also states that "Administrators can use one or more incoming parameters to configure a mapping rule for the guest portal." Therefore, option D is true.
Option A is false because remote users can sponsor any number of guest accounts, as long as they do not exceed the maximum number of guest accounts allowed by the license. Option B is false because administrators can choose to approve or reject guest accounts, or enable auto-approval.

• A. default quarantine, rspan voice video onboarding and nac_segment
• B. access, quarantine, rspan. voice, video, and onboarding
• C. default quarantine rspan voice video and nac_segment
• D. fortilink. quarantine erspan voice video and onboarding

正解：D

解説：
Explanation
According to the FortiGate Administration Guide, "When you add a FortiSwitch device to the Security Fabric, FortiGate automatically creates the following VLANs on theFortiSwitch device: fortilink, quarantine, erspan, voice, video, and onboarding." Therefore, option D is true because it lists the FortiSwitch VLANs that are automatically created on FortiGate when the first FortiSwitch device is discovered. Option A is false because default and nac_segment are not among the automatically created VLANs. Option B is false because access and rspan are not among the automatically created VLANs. Option C is false because default and nac_segment are not among the automatically created VLANs.

質問 # 26
Refer to the exhibit.

Examine the RADIUS server configuration shown in the exhibit
An administrator has configured a RADIUS server on FortiGate that points to FortiAuthenticator FortiAuthenticator is acting as an authentication proxy and is configured to relay all authentication requests to a remote Windows AD server using LDAP While testing the configuration the administrator noticed that the diagnosetest authserver command worked with PAP, however authentication requests failed when using MSCHAP2 Which two solutions can the administrator implement to get MSCHAP2 authentication to work'' (Choose two.)

• A. On FortiGate update the Secret setting on the RADIUS server
• B. On FortiAuthenticator change the back-end authentication server from LDAP to RADIUS
• C. On FortiAuthenticator enable Windows Active Directory Domain Authentication to add FortiAuthenticator to the Windows domain
• D. On FortiGate configure the NAS IP setting on the RADIUS
  server

正解：B、C

解説：
Explanation
According to the exhibit, the RADIUS server configuration on FortiGate points to FortiAuthenticator, which is acting as an authentication proxy and is configured to relay all authentication requests to a remote Windows AD server using LDAP. However, LDAP does not support MSCHAP2 authentication, which is required for RADIUS. Therefore, option A is true because on FortiAuthenticator, enabling Windows Active Directory Domain Authentication will add FortiAuthenticator to the Windows domain and allow it to use MSCHAP2 authentication with the AD server. Option C is also true because on FortiAuthenticator, changing the back-end authentication server from LDAP to RADIUS will allow it to use MSCHAP2 authentication with the AD server. Option B is false because on FortiGate, configuring the NAS IP setting on the RADIUS server will not affect the MSCHAP2 authentication, but rather the source IP address of the RADIUS packets. Option D is false because on FortiGate, updating the Secret setting on the RADIUS server will not affect the MSCHAP2 authentication, but rather the shared secret between FortiGate and FortiAuthenticator.

You are configuring a FortiGate wireless network to support automated wireless client quarantine using IOC Which two configurations must you put in place for a wireless client to be quarantined successfully? (Choose two)

• A. Configure a firewall policy to allow communication
• B. Configure the wireless network to be in tunnel mode
• C. Configure the FortiGate device in the Security Fabric with a FortiAnalyzer device
• D. Configure the wireless network to be in bridge mode

正解：B、C

解説：
Explanation
According to the FortiGate Administration Guide, "To enable automated wireless client quarantine using IOC, you must configure the following settings: Configure your wireless network to be in tunnel mode. This allows FortiGate to inspect all wireless traffic and applysecurity policies. Configure your FortiGate device in the Security Fabric with a FortiAnalyzer device. This allows FortiAnalyzer to detect indicators of compromise (IOC) from wireless traffic and send quarantine commands to FortiGate." Therefore, options A and B are true because they describe the configurations that must be put in place for a wireless client to be quarantined successfully using IOC. Option C is false because configuring a firewall policy to allow communication is not required, as the default firewall policy for tunnel mode wireless networks is to allow all traffic. Option D is false because configuring the wireless network to be in bridge mode is not supported, as FortiGate cannot inspect or quarantine wireless traffic in bridge mode.

質問 # 29

Wireless guest users are unable to authenticate because they are getting a certificate error while loading the captive portal login page.This URL string is the HTTPS POST URL guest wireless users see when attempting to access the network using the web browser

Which two settings are the likely causes of the issue? (Choose two.)

• A. The FortiGate authentication interface address is using HTTPS
• B. The wireless user's browser is missing a CA certificate
• C. The user address is not in DDNS form
• D. The external server FQDN is incorrect

正解：B、D

解説：
Explanation
According to the exhibit, the wireless guest users are getting a certificate error while loading the captive portal login page. This means that the browser cannot verify the identity of the server that is hosting the login page.
Therefore, option A is true because the external server FQDN is incorrect, which means that it does not match the common name or subject alternative name of the server certificate. Option B is also true because the wireless user's browser is missing a CA certificate, which means that it does not have the root or intermediate certificate that issued the server certificate. Option C is false because the FortiGate authentication interface address is using HTTPS, which is a secure protocol that encrypts the communication between the browser and the server. Option D is false because the user address is not in DDNS form, which is not related to the certificate error.

質問 # 30
Exhibit.

Refer to the exhibit showing a network topology and SSID settings.
FortiGate is configured to use an external captive portal However wireless users are not able to see the captive portal login page Which configuration change should the administrator make to fix the problem?

• A. Add the FortiAuthenticator and WindowsAD address objects as exempt destinations services
• B. Enable the captive-portal-exempt option in the firewall policy with the ID 12
• C. Remove the guest.portal user group in the firewall policy with the ID 12
• D. Enable NAT in the firewall policy with the ID 13.

正解：A

解説：
Explanation
According to the exhibit, the network topology and SSID settings show that FortiGate is configured to use an external captive portal hosted on FortiAuthenticator, which is connected to a Windows AD server for user authentication. However, wireless users are not able to see the captive portal login page, which means that they are not redirected to the external captive portal URL. Therefore, option B is true because adding the FortiAuthenticator and WindowsAD address objects as exempt destinations services will allow the wireless users to access the external captive portal URL without being blocked by the firewall policy. Option A is false because enabling NAT in the firewall policy with the ID 13 will not affect the redirection to the external captive portal URL, but rather the source IP address of the wireless traffic. Option C is false because enabling the captive-portal-exempt option in the firewall policy with the ID 12will bypass the captive portal authentication for the wireless users, which is not the desired outcome. Option D is false because removing the guest.portal user group in the firewall policy with the ID 12 will prevent the wireless users from being authenticated by FortiGate, which is required for accessing the external captive portal.

質問 # 31
Refer to the exhibits
