Fortinet NSE6_FWF-6.4 Fortinet NSE 6 - Secure Wireless LAN 6.4 Exam Practice Test

Answer : D

Security profiles are a feature that allows FortiAP devices to apply various security functions to the wireless traffic, such as antivirus, web filter, application control, intrusion prevention, and botnet scanning. Security profiles can be enabled on both tunnel-mode and bridge-mode SSIDs, and can be applied either through the wireless controller configuration or through firewall policies on the FortiGate device. Security profiles can also inspect encrypted wireless traffic, as long as the FortiAP device has access to the encryption keys.

Security profiles on FortiAP devices can use FortiGate subscription services to inspect the traffic, such as FortiGuard Antivirus, FortiGuard Web Filter, FortiGuard Application Control, and FortiGuard IPS. This means that the FortiAP device can leverage the latest threat intelligence and updates from Fortinet to protect the wireless network from malicious or unwanted content.

Therefore, the correct answer is D. Security profiles on FortiAP devices can use FortiGate subscription to inspect the traffic.

Answer : D

The FortiPlanner site survey reading is a tool that shows the predicted signal strength of the wireless network based on the floor plan, the placement of the APs, and the propagation model. The signal strength is measured in decibels (dB), which is a logarithmic scale that indicates how much power the signal has. The higher the dB value, the stronger the signal.

The site survey reading allows the user to set a threshold value for the signal strength, which is -68 dB by default. This means that any area with a signal strength equal or stronger than -68 dB is considered to have adequate coverage for most wireless applications. These areas are highlighted in green circles on the floor plan. Any area with a signal strength weaker than -68 dB is considered to have poor coverage or no coverage at all. These areas are shown with different colors, such as yellow, orange, red, or black, depending on how weak the signal is.

Therefore, the correct answer is D. Areas with the signal strength equal or stronger than -68 dB are highlighted in green circles.

Answer : D

Security profiles on FortiAP devices can use FortiGate subscription to inspect the traffic, such as antivirus, web filtering, application control, and IPS. This feature is called local bridging and it allows the FortiAP to forward traffic to the FortiGate for security inspection before sending it to the destination network. This reduces the bandwidth consumption and latency of tunnel mode SSIDs. Reference:Secure Wireless LAN Course Description, page 9; [FortiOS 6.4.0 Handbook - Wireless Controller], page 46.

Answer : C

The WiFi Client monitor on the FortiGate GUI shows the upstream and downstream link rates of a wireless client, along with other information such as MAC address, SSID, IP address, signal strength, and connection time. The link rates indicate the maximum data rates that the client can achieve in both directions. Reference:Secure Wireless LAN Course Description, page 7; [FortiOS 6.4.0 Handbook - Wireless Controller], page 37.

Answer : B

The wireless network interface must be assigned a Layer 3 address because it acts as the gateway for the tunnel mode SSID traffic. The FortiGate wireless controller uses this interface to communicate with the FortiAPs and the wireless clients. Without a valid IP address, the tunnel mode SSID cannot function properly. Reference:Secure Wireless LAN Course Description, page 5; [FortiOS 6.4.0 Handbook - Wireless Controller], page 24.

Answer : C

VLAN from the VLAN pool based on a hash of the current number of SSID clients and the number of entries in the VLAN pool.

Answer : B

If a bridge mode SSID is configured for a managed FortiAP, you can add a security profile group to the wireless controller, if the FortiAP model supports the security profile. This is supported only in bridge mode.
