NEW QUESTION # 17
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 FortiSwitch MAC address table is missing entries
• C. The native VLAN configured on the ports is incorrect
• D. Access VLAN is enabled on the VLAN

Answer: B

Explanation:
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.

NEW QUESTION # 18
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

Answer: A

Explanation:
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.

NEW QUESTION # 19
Refer to the exhibit

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

Answer: A,D

Explanation:
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.

NEW QUESTION # 20
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. Create a second firewall policy from port3 lo port1 and select the target destination subnets
• B. Add RSSO Group to the firewall policy
• 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

Answer: B

Explanation:
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.

NEW QUESTION # 21
Refer to the exhibit.

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

Answer: C

Explanation:
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.

NEW QUESTION # 22
Which two statements about the guest portal on FortiAuthenticator are true? (Choose two.)

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

Answer: C,D

Explanation:
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.

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

Answer: B

Explanation:
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.

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

Answer: B,C

Explanation:
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.

NEW QUESTION # 25
Refer to the exhibits.

Firewall Policy

Examine the firewall policy configuration and SSID settings
An administrator has configured a guest wireless network on FortiGate using the external captive portal The administrator has verified that the external captive portal URL is correct However wireless users are not able to see the captive portal login page Given the configuration shown in the exhibit and the SSID settings which configuration change should the administrator make to fix the problem?

• A. Disable the user group from the SSID configuration
• B. Include the wireless client subnet range in the Exempt Source section
• C. Enable the captivs-portal-exempt option in the firewall policy with the ID 11.
• D. Apply a guest.portal user group in the firewall policy with the ID 11.

Answer: D

Explanation:
Explanation
According to the FortiGate Administration Guide, "To use an external captive portal, you must configure a user group that uses the external captive portal as the authentication method and apply it to a firewall policy." Therefore, option C is true because it will allow the wireless users to be redirected to the external captive portal URL when they try to access the Internet. Option A is false because disabling the user group from the SSID configuration will prevent the wireless users from being authenticated by the FortiGate device. Option B is false because enabling the captive-portal-exempt option in the firewall policy will bypass the captive portal authentication for the wireless users, which is not the desired outcome. Option D is false because including the wireless client subnet range in the Exempt Source section will also bypass the captive portal authentication for the wireless users, which is not the desired outcome.

NEW QUESTION # 26
Refer to the exhibits

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

Answer: D

Explanation:
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.

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

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

Answer: D

Explanation:
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.

NEW QUESTION # 28
Which two statements about the MAC-based 802 1X security mode available on FortiSwitch are true? (Choose two.)

• A. FortiSwitch authenticates each device connected to the port
• B. FortiSwitch authenticates a single device and opens the port to other devices connected to the port
• C. It cannot be used in conjunction with MAC authentication bypass
• D. FortiSwitch can grant different access levels to each device connected to the port

Answer: A,D

Explanation:
Explanation
According to the FortiSwitch Administration Guide, "MAC-based 802.1X security mode allows you to authenticate each device connected to a port using its MAC address as the username and password." Therefore, option B is true because it describes the MAC-based 802.1X security mode available on FortiSwitch. Option D is also true because FortiSwitch can grant different access levels to each device connected to the port based on the user group and security policy assigned to them. Option A is false because FortiSwitch does not authenticate a single device and open the port to other devices connected to the port, but rather authenticates each device individually. Option C is false because MAC-based 802.1X security mode can be used in conjunction with MAC authentication bypass (MAB) or EAP pass-through modes, which are fallback options for non-802.1X devices.

NEW QUESTION # 29
Refer to the exhibit

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

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

Answer: B

Explanation:
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.

NEW QUESTION # 30
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. 95%
• B. 75%
• C. 85%
• D. 65%

Answer: D

Explanation:
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.

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. FortiSwitch is authenticating the client using MAC authentication bypass
• C. The client is performing user authentication
• D. The client is performing AD machine authentication

Answer: B

Explanation:
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.

NEW QUESTION # 32
