NEW QUESTION # 21
Which action does a wireless client or the access point take when the wireless client moves away from an associated AP until the signal drops?

• A. The associated AP sends an alert message to the wireless client about the signal drop.
• B. The wireless client disconnects and connects to a different, available AP.
• C. The wireless client increases its signal power to continue connecting to the same AP.
• D. The associated AP marks the wireless client as disconnected and must not reconnect.

Answer: B

Explanation:
When the client's received signal from its current AP falls below the roaming threshold, the client's roaming algorithm triggers a disconnect and then associates with a better-signal AP in the same ESS.

NEW QUESTION # 22
Refer to the exhibit. Which statement is correct about channels 52 through 144 in the 5 GHz band?

• A. The channels cannot be used because of regulatory channel restrictions.
• B. The channels are subject to dynamic frequency selection (DFS) regulations.
• C. The channels will be scanned by the wireless intrusion detection system (WIDS).
• D. The channels can be used only when Radio Resource Provisioning is enabled.

Answer: B

Explanation:
Channels 52-144 fall within the DFS-required UNII-2 and UNII-2 Extended bands, meaning APs must monitor for radar signals and vacate those frequencies if radar is detected before transmitting.

NEW QUESTION # 23
Refer to the exhibit. Why is Radio 3 used for the spectrum analysis?

• A. Radio 1 and Radio 2 are unavailable to run the spectrum analysis.
• B. Radio 3 is the configured dedicated monitoring radio for this FortiAP model.
• C. Only Radio 3 is compatible with the selected band.
• D. The 5 GHz frequency band is available only on Radio 3.

Answer: B

NEW QUESTION # 24
What protection does WPA3 wireless encryption provide over WPA2 for securing wireless networks?

• A. WPA3 uses 128-bit session key size
• B. WPA3 prevents legacy and deprecated wireless protocols from being used
• C. WPA3 enforces only enterprise security mode
• D. WPA3 addresses the KRACK vulnerability

Answer: D

Explanation:
WPA3 replaces the vulnerable four-way WPA2 handshake with SAE (Simultaneous Authentication of Equals), which provides robust forward secrecy and is not susceptible to the KRACK replay-attack flaws that affect WPA2. This ensures each session's keys cannot be recovered or reused by an attacker monitoring handshake messages.

NEW QUESTION # 25
Which benefit does 802.1X authentication offer when securing a wireless network?

• A. Simplifies public Wi-Fi hotspots for guest access
• B. Authentication and authorization in enterprise networks
• C. Makes wireless access at home protected and secured
• D. Allows administrators to gain elevated privilege to access resources

Answer: B

Explanation:
802.1X implements port-based access control by authenticating each supplicant device against a RADIUS server (or equivalent) before opening the port, ensuring only authorized users and devices can join the enterprise LAN or WLAN.

NEW QUESTION # 26
You have just authorized a newly added FortiAP device on FortiGate. It went offline for an extended time without coming back online again. What troubleshooting process must you take to bring FortiAP back online?

• A. Check the power feed to the FortiAP device and PoE status if powered by a switch.
• B. Verify that communication between FortiAP and the wireless controller is not blocked.
• C. Access FortiAP management using HTTPs.
• D. Restart the wireless controller if it is unresponsive for the newly added FortiAP device.

Answer: B

NEW QUESTION # 27
Refer to the exhibits. User1 is part of the infrastructure department and connects to the ONBOARD wireless network using the credentials user1. However, the dynamic VLAN assignment is not working.
Which configuration step must you take to fix this issue?

• A. Disable the DHCP server on ONBOARD to allow VLAN assignment.
• B. Add user1 in one of the VLAN names.
• C. Update user1 RADIUS attributes to include a VLAN ID attribute ID.
• D. Create a new VLAN name "infrastructure" with a VLAN ID associated with it.

Answer: D

Explanation:
For dynamic-VLAN assignment FortiGate matches the RADIUS Tunnel-Private-Group-Id string against the VLAN names you've configured under that SSID. Since you sent "infrastructure" but only have "data" and "iot" defined, you must add an "infrastructure" VLAN entry (with its VLAN ID) to the WLAN01 profile so the RADIUS attribute can map correctly.

NEW QUESTION # 28
Which wireless monitoring metric is required to optimize a wireless network?

• A. Wireless channel utilization
• B. FortiAP running firmware status
• C. Amount of event logs generated
• D. Users count on the network

Answer: A

Explanation:
Monitoring channel utilization tells you how busy each RF channel is highlighting congestion, co- channel interference, and idle capacity, so you can adjust channel assignments and power settings to optimize overall network performance.

NEW QUESTION # 29
Which modulation scheme offers extremely high throughput (EHT) in 802.11be technology?

• A. Orthogonal frequency division multiplexing
• B. Direct sequence spread spectrum
• C. Binary phase-shift keying
• D. Quadrature amplitude modulation

Answer: D

NEW QUESTION # 30
When preauthorizing an AP in the GUI, which minimum configuration parameter is required to add an AP?

• A. The AP serial number
• B. The AP serial number and FortiAP Profile
• C. The FortiAP Profile and AP name
• D. The AP serial number, FortiAP Profile, and AP login password

Answer: B

NEW QUESTION # 31
Refer to the exhibits. The exhibits show the AP profile, the controller RF analysis output, and a diagnostic summary of the AP and neighboring APs.
The wireless network is used for multiple purposes, including corporate access, guest access, and connecting point-of-sale and IoT devices. Users connecting to the guest network located in the reception area are reporting slow performance.
Which configuration change is most likely to improve performance?

• A. Reduce the number of SSIDs being broadcast by the reception AP.
• B. Increase the transmission power of the AP radios.
• C. Install another AP in the reception area to improve available bandwidth.
• D. Enable frequency handoff on the AP to band steer clients.

Answer: A

Explanation:
Every SSID (VAP) generates its own beacon and management frames, which on a heavily- utilized 2.4 GHz channel (91 % busy) adds significant overhead and cuts into airtime for client data. By cutting back to only the SSIDs needed in the reception area (for example, Guest and perhaps one additional SSID), you'll reduce beacon traffic and free up more of that already- scarce airtime for user throughput.

NEW QUESTION # 32
Employees at the remote office reported speed issues with the wireless network. Dual-band FortiAP devices have been correctly deployed throughout the office to ensure coverage and optimal performance. However, employees have noticed that the wireless stations consistently connect to the 2.4 GHz network but not the 5 GHz network.
What must IT administrators perform to troubleshoot the issue?

• A. Review if FortiAP resources are not experiencing high CPU or memory usage.
• B. Confirm whether internet speed limits are preventing access to high speed by wireless stations.
• C. Verify that the allocated frequency channel on FortiAP is not exhausted.
• D. Disable the 2.4 GHz radio to force the wireless stations to connect.

Answer: C

NEW QUESTION # 33
Refer to the exhibit. An administrator authorizes two FortiAP devices connected to this wireless controller. However, one FortiAP is not able to broadcast the SSIDs.
What must the administrator do to fix the issue?

• A. Enable the radios on the FAP23JF FortiAP profile.
• B. Disable the override setting on the FortiAP that is preventing it from broadcasting SSIDs.
• C. Replace the FortiAP device model to match the other device.
• D. Assign the FAP231F FortiAP profile to the problematic FortiAP device.

Answer: A

Explanation:
On the problem AP you can see "Channel 0" and all three SSID slots show "N/A," which means its radios are turned off in its FortiAP profile. Simply edit the FAP23JF profile, enable the 2.4 GHz/5 GHz radios and assign the SSIDs (or inherit the global SSIDs), and the AP will begin broadcasting normally.

NEW QUESTION # 34
Refer to the exhibit. The wireless station with MAC address 5a:29:94:87:f7:b8 has made multiple attempts to connect to the CORP_DATA SSID. Despite client-association-failure event logs, the wireless station connects on the final attempt.
Why did the wireless station fail to connect initially?

• A. The wireless station was incompatible with the 5 GHz radio band.
• B. The wireless station connected to SSID but failed RADIUS authentication.
• C. The wireless controller unauthenticated the wireless station to prevent evil twin attacks.
• D. The wireless station used invalid credentials on the failed attempt.

Answer: B

Explanation:
The event log shows a client-association-failure with the message "RADIUS authentication failure" on the first attempts, indicating the supplicant reached the AP but the RADIUS server rejected the credentials. On the final try, valid credentials were supplied and the 4-way handshake completed successfully.

NEW QUESTION # 35
A FortiAP device is connected directly to a FortiGate interface.
What discovery method will be used to provision the FortiAP device?

• A. FortiGate discovers the FortiAP through the received broadcast packets.
• B. FortiAP discovers FortiGate by reviewing the vendor class value.
• C. FortiAP discovers FortiGate by connecting to FortiLAN Cloud to verify its management license.
• D. FortiGate discovers the FortiAP IP address from DHCP option 138.

Answer: A

NEW QUESTION # 36
Refer to the exhibit. FortiGate sends logs to FortiAnalyzer using the default settings to report security events for all wireless stations as part of the Security Fabric configuration.
Which security action will FortiGate take when it detects a compromised wireless station in the CORP_DATA SSID?

• A. FortiGate disassociates compromised stations and prevents them from connecting again.
• B. CORP_DATA is in NAC mode and onboards compromised stations for a period until malicious activity stops.
• C. FortiAP devices broadcasting CORP_DATA wireless network place compromised stations in quarantine.
• D. FortiAnalyzer generates security reports to inform security operations to further investigate the compromised stations.

Answer: C

Explanation:
By assigning the CORP_DATA SSID a NAC profile (Tunnel-NAC) with "Quarantine host" enabled, the FortiGate instructs the FortiAPs to immediately isolate any client flagged as compromised, placing it into the quarantine segment (where only remediation services are reachable) even though it remains associated to the SSID. This ensures all remediation and blocking is enforced in real time at the AP.
