Fortinet FCP_FWF_AD-7.4 Exam With Confidence Using Practice Dumps

Exhibit Analysis:

The diagram shows a section of the 5 GHz Wi-Fi band, with several adjacent channels: 149, 153, 157, 161.

The red line outlines a wider frequency range covering multiple adjacent channels (149, 153, 157).

What this means:

In Wi-Fi (especially 802.11ac/ax), “channel bonding” means combining adjacent 20 MHz channels into a wider channel (40, 80, or even 160 MHz).

The red line indicates the frequency range that would be used if an 80 MHz channel (covering channels 149, 153, 157, 161) is formed by bonding the narrower channels together.

This increases throughput because a wider channel allows more data to be transmitted at once.

Option Review:

A. Practical channel bonding to increase high throughput

Correct. The red line represents the spectrum occupied when several 20 MHz channels are bonded into a single, wider channel to increase data rates.

B. A pool of channels for the wireless radio to broadcast the wireless signal.

Incorrect. A pool would be all available channels, not the bonded range.

C. The range of channels used to allocate available airtime while transmitting data

Incorrect. This is about frequency, not time.

D. The total length of the wireless signal wavelength

Incorrect. The line indicates frequency spectrum, not wavelength length.

Summary:

The red line shows how multiple adjacent 20 MHz channels are bonded together (in this case, most likely into an 80 MHz channel), a practical method to increase wireless throughput in modern Wi-Fi networks.

Scenario:

The IT department wants to prevent direct communication between wireless stations.

There is one SSID configured in bridge mode (all clients on the same SSID/VLAN, directly bridging to the wired network).

Correct Action:

Block intra-SSID traffic (sometimes called “client isolation” or “intra-SSID privacy”).

This feature prevents wireless clients connected to the same SSID from communicating directly with each other at Layer 2.

Each station can reach the network but cannot reach other wireless clients on the same SSID.

This is the industry-standard method to achieve the stated security goal in a wireless environment, especially in bridge mode.

Why Other Options Are Incorrect:

A. Create unique SSIDs for each FortiAP device

Impractical and unnecessary for user isolation; users on the same SSID but different APs can still be isolated with intra-SSID blocking.

B. Add an upstream layer 3 device on each FortiAP device

Overkill and not required; this does not directly solve intra-SSID traffic.

D. Drop all local traffic in the wireless network

Too broad; you only want to prevent client-to-client communication, not all local traffic (such as traffic to the gateway).

Summary:

Block intra-SSID traffic is the intended and correct configuration to prevent wireless stations from communicating directly while sharing the same SSID in bridge mode.

When a client moves out of range, the connection drops.

The normal behavior is for the client to disconnect and then seek out and connect to another AP with a stronger signal.

The AP does not force disconnection or send alerts; the client handles roaming.

Clients do not increase their own radio power substantially in response to poor signals due to hardware limits.
