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.

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.

According to the FortiGate Administration Guide, “To use certificate-based authentication, you must configure the following settings on both peers: Select Signature as the authentication method and select a certificate to use for authentication. Import the CA certificate that issued the peer’s certificate. Enable XAUTH on the phase 1 configuration.” Therefore, options B, D, and E are true because they describe the configuration changes that must be made on FortiGate to perform certificate-based authentication for the IPsec VPN user. Option A is false because creating a PKI user for the IPsec VPN user is not required, as the user certificate can be verified by the CA certificate. Option C is false because changing the IKE mode to Main (ID protection) is not required, as the IKE mode can be either Main or Aggressive for certificate-based authentication.

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.

According to the FortiAP Configuration Guide1, “Auto TX power control allows the AP to adjust its transmit power based on the signal strength of the client. The AP will measure the signal strength of the client every 30 seconds and adjust its transmit power up or down until the client signal is detected at -70 dBm.” Therefore, option A is true because it describes how the FortiAP wireless interface configures its transmission power when auto TX power control is enabled. Option B is false because FortiGate does not measure the signal strength of adjacent AP interfaces, but rather the FortiAP does. Option C is false because FortiGate does not adjust the adjacent AP power, but rather the FortiAP adjusts its own power. Option D is false becauseFortiGate does not measure the signal strength of the weakest associated client, but rather the FortiAP does.

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.

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.

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.
