質問 # 23
Refer to the exhibit.
If the signal is set to -68 dB on the FortiPlanner site survey reading, which statement is correct regarding the coverage area?
- A. Areas with the signal strength equal to -68 dB are zoomed in to providebetter visibility.
- B. Areas with the signal strength weaker than -68 dB are highlighted in orangeand red to indicate that no signal was propagated by the APS.
- C. Areas with the signal strength weaker than -68 dB are shown with blackbackground.
- D. Areas with the signal strength equal or stronger than -68 dB are highlighted in green circles.
正解：D
解説：
Explanation
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.

質問 # 34
Which two statements about distributed automatic radio resource provisioning (DARRP) are correct? (Choose two.)
- A. DARRP performs measurements of the number of BSSIDs and their signal strength (RSSI). The controller then uses this information to select the optimum channel for the AP.

質問 # 37
You are investigating a wireless performance issue and you are trying to audit the neighboring APs in the PF environment. You review the Rogue APs widget on the GUI but it is empty, despite the known presence of other APs.
Which configuration change will allow neighboring APs to be successfully detected?
- A. Enable Radio resource provisioning on the relevant AP profiles.
- B. Ensure that all allowed channels are enabled for the AP radios.
- C. Enable Monitor channel utilization on the relevant AP profiles.
- D. Enable Locate WiFi clients when not connected in the relevant AP profiles.
正解：A
解説：
Explanation
The ARRP (Automatic Radio Resource Provisioning) profile improves upon DARRP (Distributed Automatic Radio Resource Provisioning) by allowing more factors to be considered to optimize channel selection among FortiAPs. DARRP uses the neighbor APs channels and signal strength collected from the background scan for channel selection.

質問 # 39
Which statement is correct about security profiles on FortiAP devices?
- A. Security profiles are only supported on Bridge-mode SSIDs.
- B. Security profiles can only be applied to unencrypted wireless traffic.
- C. Security profiles on FortiAP devices can use FortiGate subscription to inspect the traffic.
- D. Security profiles can only be applied via firewall policies on the FortiGate.
正解：C
解説：
Explanation
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.
