• BAllowing unrestricted guest access
• CAllowing unrestricted guest access
• DDisabling firewall protections

• A

• C

• D

Explanation

WPA3 (Wi-Fi Protected Access 3) is the current gold standard for wireless encryption, offering stronger cryptographic protections, improved password-based authentication (SAE/Dragonfly handshake), and forward secrecy - meaning past sessions can't be decrypted even if a key is later compromised.

Options B and C (identical distractors) describe unrestricted guest access, which does the opposite of improving security - it opens the network to unknown devices and potential attackers with no authentication barrier.

Option D is equally harmful: disabling a firewall removes a critical layer of defense against unauthorized traffic, leaving the network exposed to both external and internal threats.

Memory tip: Think of WPA3 as the "lock upgrade" - just as you'd upgrade a deadbolt to improve home security, upgrading to WPA3 is the direct, active measure that adds protection. Any answer that removes controls (firewalls, access restrictions) is always wrong in a security context.
