Examine the FortiSwitch security policy shown in the exhibit
If the security profile shown in the exhibit is assigned to all ports on a FortiSwitch device for 802 1X authentication which statement about the switch is correct?

  • A. FortiSwitch will assign non-802 1X devices to the onboarding VLAN
  • B. FortiSwitch will try to authenticate non-802 1X devices using the device MAC address as the username and password
  • C. FortiSwitch cannot authenticate multiple devices connected to the same port
  • D. All EAP messages will be terminated on FortiSwitch

正解:A

解説:
Explanation
According to the FortiSwitch Administration Guide, "If a device does not support 802.1X authentication, you can configure the switch to assign the device to an onboarding VLAN. The onboarding VLAN is a separate VLAN that you can use to provide limited network access to non-802.1X devices." Therefore, option C is true because it describes the behavior of FortiSwitch when the security profile shown in the exhibit is assigned to all ports. Option A is false because FortiSwitch can authenticate multiple devices connected to the same port using MAC-based or MAB-EAP modes. Option B is false because FortiSwitch will not try to authenticate non-802.1X devices using the device MAC address as the username and password, but rather use MAC authentication bypass (MAB) or EAP pass-through modes. Option D is false because all EAP messages will be terminated on FortiGate, not FortiSwitch, when using 802.1X authentication.

Refer to the exhibits.

Exhibit.

Examine the troubleshooting outputs shown in the exhibits
Users have been reporting issues with the speed of their wireless connection in a particular part of the wireless network The interface that is having issues is the 2 4 GHz interface that is currently configured on channel 6 The administrator of the wireless network has investigated and surveyed the local RF environment using the tools available at the AP and FortiGate Which configuration would improve the wireless connection?

  • A. Change the AP 2 4 GHz channel to 11
  • B. Change the AP 2 4 GHz channel to 9.
  • C. Change the AP 2 4 GHz channel to 13.
  • D. Change the AP 2 4 GHz channel to 1.

正解:D

解説:
Explanation
According to the exhibits, the AP 2.4 GHz interface is currently configured on channel 6, which is overlapping with other nearby APs on channels 4 and 8. This can cause interference and reduce the wireless performance.
Therefore, changing the AP 2.4 GHz channel to 1 would improve the wireless connection, as it would avoid the overlapping channels and use a non-overlapping channel instead. Option A is false because changing the AP 2.4 GHz channel to 11 would still overlap with other nearby APs on channels 9 and 13. Option C is false because changing the AP 2.4 GHz channel to 9 would still overlap with other nearby APs on channels 6, 8, and 11. Option D is false because changing the AP 2.4 GHz channel to 13 would still overlap with other nearby APs on channels 9 and 11.


質問 # 15
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 quarantined device is kept in the current VLAN
  • C. The device MACaddress is added to the Quarantined Devices firewall address group
  • D. It is the default mode for MAC address quarantine

正解:B、C

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 FortiManager information shown in the exhibit
Which two statements about the FortiManager status are true'' (Choose two)

  • A. FortiSwitch is authorized and offline
  • B. FortiSwitch manager is working in central management mode
  • C. FortiSwitch is not authorized
  • D. FortiSwitch manager is working in per-device management mode

正解:A、B

解説:
Explanation
According to the FortiManager Administration Guide, "Central management mode allows you to manage all FortiSwitch devices from a single interface on the FortiManager device." Therefore, option C is true because the exhibit shows that the FortiSwitch manager is enabled and the FortiSwitch device is managed by the FortiManager device. Option D is also true because the exhibit shows that the FortiSwitch device status is offline, which means that it is not reachable by the FortiManager device, but it is authorized, which means that it has been added to the FortiManager device. Option A is false because per-device management mode allows you to manage each FortiSwitch device individually from its own web-based manager or CLI, which is not the case in the exhibit. Option B is false because the FortiSwitch device is authorized, as explained above.


質問 # 17
Refer to the exhibit.

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

正解:B

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.

Exhibit.

Exhibit.

Refer to the exhibits
In the wireless configuration shown in the exhibits, an AP is deployed in a remote site and has a wireless network (VAP) called Corporate deployed to it The network is a tunneled network however clients connecting to a wireless network require access to a local printer Clients are trying to print to a printer on the remote site but are unable to do so Which configuration change is required to allow clients connected to the Corporate SSID to print locally?

  • A. Configure the printer as a wireless client on the Corporate wireless network
  • B. Configure split-tunneling in the wtp-profile configuration
  • C. Disable the Block Intra-SSID Traffic (intra-vap-privacy) setting on the SSID (VAP) profile
  • D. Configure split-tunneling in the vap configuration

正解:D

解説:
Explanation
According to the Fortinet documentation1, "Split tunneling allows you to specify which traffic is tunneled to the FortiGate and which traffic is sent directly to the Internet. This can improve performance and reduce bandwidth usage." Therefore, by configuring split-tunneling in the vap configuration, you can allow the clients connected to the Corporate SSID to access both the corporate network and the local printer. Option B is incorrect because split-tunneling is configured at the vap level, not the wtp-profile level. Option C is incorrect because blocking intra-SSID traffic prevents wireless clients on the same SSID from communicating with each other, which is not related to accessing a local printer. Option D is unnecessary and impractical because the printer does not need to be a wireless client on the Corporate wireless network to be accessible by the clients.


質問 # 19
Which EAP method requires the use of a digital certificate on both the server end and the client end?

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

正解:A

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.

A device connected to port2 on FortiSwitch cannot access the network The port is assigned a security policy to enforce 802 1X authentication While troubleshooting the issue, the administrator obtains the debug output shown in the exhibit Which two scenarios are likely to cause this issue? (Choose two.)

  • A. The device has been quarantined for 3600 seconds.
  • B. The device has been assigned the guest VLAN
  • C. The device does not support 802 1X authentication
  • D. The device is not configured for 802 IX authentication.

正解:C、D

解説:
Explanation
According to the exhibit, the debug output shows that the device connected to port2 on FortiSwitch is sending an EAPOL-Start message, which is the first step of the 802.1X authentication process. However, the output also shows that the device is not sending any EAP-Response messages, which are required to complete the authentication process. Therefore, option A is true because the device is not configured for 802.1X authentication, which means that it does not have the correct credentials or settings to authenticate with the RADIUS server. Option D is also true because the device does not support 802.1X authentication, which means that it does not have the capability or software to perform 802.1X authentication. Option B is false because the device has not been quarantined for 3600 seconds, but rather has a session timeout of 3600 seconds, which is the default value for 802.1X sessions. Option C is false because the device has not been assigned the guest VLAN, but rather has been assigned the default VLAN, which is VLAN 1.

The exhibits show the wireless network (VAP) SSID profiles defined on FortiManager and an AP profile assigned to a group of APs that are supported by FortiGate None of the APs are broadcasting the SSlDs defined by the AP profile Which changes do you need to make to enable the SSIDs to broadcast?

  • A. In the SSIDs section enable Tunnel
  • B. In the SSIDs section enable Manual and assign the networks manually
  • C. Enable multiple channels in the Channels section and enable Radio Resource Provision
  • D. Enable one channel in the Channels section

正解:D

解説:
Explanation
According to the FortiManager Administration Guide1, "To enable the SSID, you must select at least one channel for the radio. If no channels are selected, the SSID will not be enabled." Therefore, enabling one channel in the Channels section will allow the SSIDs to broadcast.

Examine the sections of the configuration shown in the output
What action will FortiGate take when verifying the student certificate through OCSP?

  • A. Use the OCSP URL included in the student certificate to verify the student certificate
  • B. Consider the student certificate status as valid if the OCSP server is unreachable
  • C. Not verify the OCSP server certificate
  • D. Reject the student certificate if the OCSP server replies that the student certificate status is unknown

正解:A

解説:
Explanation
According to the exhibit, the FortiGate configuration has ocsp-status enabled and ocsp-option set to certificate.
This means that FortiGate will use OCSP to verify the revocation status of certificates presented by clients. According to the FortiGate Administration Guide2, "If you select certificate, FortiGate uses an OCSP URL included in a certificate to verify that certificate." Therefore, option C is true because it describes what action FortiGate will take when verifying the student certificate through OCSP. Option A is false because FortiGate will not reject the student certificate if the OCSP server replies that the student certificate status is unknown, but rather accept it as valid. Option B is false because FortiGate will verify the OCSPserver certificate by default, unless strict-ocsp-check is disabled. Option D is false because FortiGate will not consider the student certificate status as valid if the OCSP server is unreachable, but rather reject it as invalid.


質問 # 23
You are setting up an SSID (VAP) to perform RADlUS-authenticated dynamic VLAN allocation Which three RADIUS attributes must be supplied by the RADIUS server to enable successful VLAN allocation'' (Choose three.)

  • A. Tunnel-Private-Group-ID
  • B. Tunnel-Preference
  • C. Tunnel-Medium-Type
  • D. Tunnel-Pvt-Group-ID
  • E. Tunnel-Type

正解:A、C、E

解説:
Explanation
According to the FortiAP Configuration Guide, "To perform RADIUS-authenticated dynamic VLAN allocation, the RADIUS server must supply the following RADIUS attributes: Tunnel-Private-Group-ID, which specifies the VLAN ID to assign to the user. Tunnel-Type, which specifies the tunneling protocol used for the VLAN. The value must be 13 (VLAN). Tunnel-Medium-Type, which specifies the transport medium used for the VLAN. The value must be 6 (802). Therefore, options A, D, and E are true because they describe the RADIUS attributes that must be supplied by the RADIUS server to enable successful VLAN allocation.
Option B is false because Tunnel-Pvt-Group-ID is not a valid RADIUS attribute name, but rather a typo for Tunnel-Private-Group-ID. Option C is false because Tunnel-Preference is not a required RADIUS attribute for dynamic VLAN allocation, but rather an optional attribute that specifies the priority of the VLAN.


質問 # 24
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 the wireless network to be in bridge mode
  • 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 a firewall policy to allow communication

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 # 25
You are investigating a report of poor wireless performance in a network that you manage. The issue is related to an AP interface in the 5 GHz range You are monitoring the channel utilization over time.
What is the recommended maximum utilization value that an interface should not exceed?

  • A. 65%
  • B. 95%
  • C. 75%
  • D. 85%

正解:A

解説:
Explanation
According to the FortiAP Configuration Guide, "Channel utilization measures how busy a channel is over a given period of time. It includes both Wi-Fi and non-Wi-Fi interference sources. A high channel utilization indicates a congested channel and can result in poor wireless performance. The recommended maximum utilization value that an interface should not exceed is 65%." Therefore, option D is true because it gives the recommended maximum utilization value for an interface in the 5 GHz range. Options A, B, and C are false because they give higher utilization values that can cause poor wireless performance.

(Choose two)

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

正解:A、D

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 # 27
Where can FortiGate learn the FortiManager IP address or FQDN for zero-touch provisioning'?

  • A. From a TFTP server
  • B. From a DHCP server using options 240 and 241
  • C. From a DNS server using A or AAAA records
  • D. From an LDAP server using a simple bind operation

正解:C

解説:
Explanation
According to the FortiGate Administration Guide, "FortiGate can learn the FortiManager IP address or FQDN for zero-touch provisioning from a DNS server using A or AAAA records. The DNS server must be configured to resolve the hostname fortimanager.fortinet.com to the IP address or FQDN of the FortiManager device." Therefore, option D is true because it describes the method for FortiGate to learn the FortiManager IP address or FQDN for zero-touch provisioning. Option A is false because LDAP is not used for zero-touch provisioning. Option B is false because TFTP is not used for zero-touch provisioning. Option C is false because DHCP options 240 and 241 are not used for zero-touch provisioning.


質問 # 28
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. Enable NAT in the firewall policy with the ID 13.
  • D. Remove the guest.portal user group in the firewall policy with the ID 12

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.
