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

Answer : B, C

According to Fortinet training: 'When using DARRP, the AP selects the best channel available to use based on the scan results of BSSID/receive signal strength (RSSI) to AC' and 'To set the running time for DARRP optimization, use the following CLI command within the wireless controller setting: set darrp-optimize {integer}. Note that DARRP doesn't do continuous spectrum analysis...'

Answer : A, C

The configuration changes that will resolve the issue are to configure set vaps to be ''Authors'' for both interfaces in the wtp-profile, and to configure vap-all to be manual for both interfaces in the wtp-profile. This is because the current configuration does not assign any VAPs to the AP interfaces, which means that no wireless networks are broadcasted by the APs. The vap-all setting determines whether all VAPs are assigned to an interface or not, and the vaps setting specifies which VAPs are assigned to an interface. By setting vap-all to manual and vaps to ''Authors'', the APs will only broadcast the Authors wireless network on both interfaces. Disabling intra-vap-privacy for the Authors vap-wireless network will not help, as it only affects the communication between clients on the same SSID, not their connection to the AP. Increasing the transmission power of the AP radio interfaces will not help, as it only affects the signal strength and coverage of the APs, not their broadcasting of wireless networks.

Answer : B

FortiPlanner is a wireless network planning and deployment tool that helps to design and optimize wireless networks based on various parameters, such as floor plans, AP models, coverage areas, and client density. FortiPlanner uses a predictive model in wireless design projects, which means that it estimates the wireless coverage and performance based on mathematical calculations and simulations, without requiring any physical measurements or site surveys.

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.
