Which of the following provides the GREATEST security for SOHO wireless?
The correct answer is A. Enable a shared WPA key. WPA (Wi-Fi Protected Access) with a shared key provides actual cryptographic encryption for wireless traffic, making it the strongest security option listed for SOHO networks.

Why each option
WPA (Wi-Fi Protected Access) with a shared key provides actual cryptographic encryption for wireless traffic, making it the strongest security option listed for SOHO networks.
WPA uses TKIP or AES-based encryption to protect data in transit over the wireless network, requiring authentication before granting access and making it significantly harder for attackers to intercept or join the network compared to the other listed options.
MAC filtering can be easily bypassed by an attacker who spoofs a whitelisted MAC address and provides no data encryption.
Using the highest transmit power increases the signal range, which actually expands the attack surface rather than improving security.
Disabling SSID broadcast is security through obscurity - the network is still discoverable with passive wireless scanning tools and provides no encryption.
