Question 1

What type of design model does FortiPlanner use in wireless design project?

AArchitectural model

BPredictive model

CAnalytical model

DIntegration model

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. Reference:FortiOS 6.4.0 Handbook - Wireless Controller, page 5; [FortiPlanner User Guide], page 9.

Question 2

How are wireless clients assigned to a dynamic VLAN configured for hash mode?

AUsing the current number of wireless clients connected to the SSID and the number of IPs available in the least busy VLAN

BUsing the current number of wireless clients connected to the SSID and the number of clients allocated to each of the VLANs

CUsing the current number of wireless clients connected to the SSID and the number of VLANs available in the pool

DUsing the current number of wireless clients connected to the SSID and the group the FortiAP is a member of

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.

Question 3

Six APs are located in a remotely based branch office and are managed by a centrally hosted FortiGate. Multiple wireless users frequently connect and roam between the APs in the remote office.

The network they connect to, is secured with WPA2-PSK. As currently configured, the WAN connection between the branch office and the centrally hosted FortiGate is unreliable.

Which configuration would enable the most reliable wireless connectivity for the remote clients?

AConfigure a tunnel mode wireless network and enable split tunneling to the local network

BConfigure a bridge mode wireless network and enable the Local standalone configuration option

CConfigure a bridge mode wireless network and enable the Local authentication configuration option

DInstall supported FortiAP and configure a bridge mode wireless network

Question 4

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?

AIncrease the transmission power of the AP radios

BEnable frequency handoff on the AP to band steer clients

CReduce the number of wireless networks being broadcast by the AP

DInstall another AP in the reception area to improve available bandwidth

Answer : B

Question 5

When configuring Auto TX Power control on an AP radio, which two statements best describe how the radio responds? (Choose two.)

AWhen 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.

BWhen 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.

CWhen 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.

DWhen 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.

Answer : A, D

According to the web search results, Auto TX Power control is a feature that allows the AP to automatically adjust its transmission power based on the RF environment. The goal is to minimize interference and optimize coverage cells for roaming. When the AP detects any other wireless signal stronger than -70 dBm, it means that there is a potential source of interference nearby, so it will reduce its transmission power until it reaches the minimum configured TX power limit. This will reduce the interference and improve coexistence with other devices. When the AP detects any interference from a trusted neighboring AP stronger than -70 dBm, it means that there is a high density of APs in the area, so it will also reduce its transmission power until it reaches the minimum configured TX power limit. This will balance the load and avoid overlapping coverage areas.

Question 6

Which administrative access method must be enabled on a FortiGate interface to allow APs to connect and function?

ASecurity Fabric Connection

BSSH

CHTTPS

DFortiTelemetry

Answer : A

Question 7

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 weaker than -68 dB are shown with black background.

B. Areas with the signal strength equal to -68 dB are zoomed in to provide better visibility.

C. Areas with the signal strength weaker than -68 dB are highlighted in orange and red to indicate that no signal was propagated by the APS.

DAreas with the signal strength equal or stronger than -68 dB are highlighted in green circles.

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.
