Which two statements about distributed automatic radio resource provisioning (DARRP) are correct? (Choose two.)
- A. DARRP performs continuous spectrum analysis to detect sources of interference. It uses this information to allow the AP to select the optimum channel.
- B. 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.
- C. DARRP measurements can be scheduled to occur at specific times.
- D. DARRP requires that wireless intrusion detection (WIDS) be enabled to detect neighboring devices.
Answer : AD
Explanation:
DARRP (Distributed Automatic Radio Resource Provisioning) technology ensures the wireless infrastructure is always optimized to deliver maximum performance.
Fortinet APs enabled with this advanced feature continuously monitor the RF environment for interference, noise and signals from neighboring APs, enabling the
FortiGate WLAN Controller to determine the optimal RF power levels for each AP on the network. When a new AP is provisioned, DARRP also ensures that it chooses the optimal channel, without administrator intervention.

Which factor is the best indicator of wireless client connection quality?
- A. Downstream link rate, the connection rate for the AP to the client
- B. The receive signal strength (RSS) of the client at the AP
- C. Upstream link rate, the connection rate for the client to the AP
- D. The channel utilization of the channel the client is using
Answer : B
Explanation:
SSI, or ג€Received Signal Strength Indicator,ג€ is a measurement of how well your device can hear a signal from an access point or router. Itג€™s a value that is useful for determining if you have enough signal to get a good wireless connection.

When configuring Auto TX Power control on an AP radio, which two statements best describe how the radio responds? (Choose two.)
- A. When the AP detects any other wireless signal stronger that -70 dBm, it will reduce its transmission power until it reaches the minimum configured TX power limit.
- B. When the AP detects PF Interference from an unknown source such as a cordless phone with a signal stronger that -70 dBm, it will increase its transmission power until it reaches the maximum configured TX power limit.
- C. When the AP detects any wireless client signal weaker than -70 dBm, it will reduce its transmission power until it reaches the maximum configured TX power limit.
- D. When the AP detects any interference from a trusted neighboring AP stronger that -70 dBm, it will reduce its transmission power until it reaches the minimum configured TX power limit.

Refer to the exhibits.
Exhibit A.
Exhibit B.
Exhibit C.
A wireless network has been installed in a small office building and is being used by a business to connect its wireless clients. The network is used for multiple purposes, including corporate access, guest access, and connecting point-of-sale and Io׀¢ devices.
Users connecting to the guest network located in the reception area are reporting slow performance. The network administrator is reviewing the information shown in the exhibits as part of the ongoing investigation of the problem. They show the profile used for the AP and the controller RF analysis output together with a screenshot of the GUI showing a summary of the AP and its neighboring APs.
To improve performance for the users connecting to the guest network in this area, which configuration change is most likely to improve performance?
- A. Increase the transmission power of the AP radios
- B. Enable frequency handoff on the AP to band steer clients
- C. Reduce the number of wireless networks being broadcast by the AP
- D. Install another AP in the reception area to improve available bandwidth
Answer : A
Which two statements about background rogue scanning are correct? (Choose two.)
- A. A dedicated radio configured for background scanning can support the connection of wireless clients
- B. When detecting rogue APs, a dedicated radio configured for background scanning can suppress the rogue AP
- C. Background rogue scanning requires DARRP to be enabled on the AP instance
- D. A dedicated radio configured for background scanning can detect rogue devices on all other channels in its configured frequency band.
Answer : AB
Explanation:
