Zorluk: OrtaWireless Security and Authentication

A network technician deploys a new wireless access point configured to operate exclusively in WPA3-Personal mode. While modern company laptops connect successfully, several older Wi-Fi 4 (802.11n) handheld inventory scanners are unable to associate with the wireless network. The technician must allow these legacy handheld scanners to connect without forcing the modern laptops to downgrade their security protocol. Which of the following configuration changes should the technician make on the access point?

  1. Enable WPA2/WPA3 transition mode on the wireless access point.Cevap
  2. B
    Change the wireless encryption standard from AES-CCMP to WPA-TKIP.
  3. C
    Switch the authentication mode to WPA2-Enterprise with PSK fallback.
  4. D
    Disable Protected Management Frames (PMF) on the access point while maintaining WPA3-Only mode.

Cevap

Enabling WPA2/WPA3 transition mode allows legacy WPA2 devices to connect using PSK while allowing supported modern devices to connect via WPA3 (SAE).
Enabling WPA2/WPA3 transition mode provides backward compatibility. It allows legacy clients that only support WPA2-PSK (AES) to connect to the SSID while allowing newer clients to authenticate using WPA3-Personal (SAE) with mandatory Protected Management Frames.

Adım Adım Çözüm

1
Analyze the connectivity issue.
Modern devices connect via WPA3-Personal, but legacy Wi-Fi 4 devices fail because they lack WPA3/SAE hardware or firmware support.
WPA3-Only mode strictly requires client support for SAE and mandatory Protected Management Frames (PMF).
2
Evaluate compatibility options that maintain security for modern clients.
WPA2/WPA3 Mixed or Transition Mode enables dual-SSID broadcasting capabilities under a single SSID, supporting WPA3-SAE for capable clients and falling back to WPA2-PSK for legacy devices.
This satisfies the requirement to support legacy scanners without forcing modern devices down to WPA2-only.
