   A security auditor is assessing a wireless network that uses WPA2-Personal with a weak passphrase. The auditor recommends upgrading to WPA3. What is the main security improvement that WPA3 provides over WPA2?

   • AWPA3 automatically changes the passphrase periodically.
   • BWPA3 uses a longer passphrase by default.
   • CWPA3 provides stronger encryption using AES-256.
   • DWPA3 uses Simultaneous Authentication of Equals (SAE) to resist offline dictionary attacks.

   A company's legacy wireless network uses WEP. The security team wants to migrate to a more secure protocol but some older devices only support WEP. What is the best approach to maintain security while supporting these legacy devices?

   • AUpgrade all devices to support WPA2, even if it requires replacing them.
   • BKeep WEP on a separate SSID for legacy devices and use WPA2/WPA3 for all other devices.
   • CUse WEP with a longer key to improve security.
   • DDisable all wireless access until all devices are upgraded.
