A client wants a wireless network set up in the office, but does not want unauthorized users to be able to access the network. Which of the following provides the BEST protection?
The correct answer is D. Strong encryption. Strong encryption (such as WPA2 or WPA3) is the best protection against unauthorized access because it requires a valid passphrase or credentials to decrypt and use the network, even if someone discovers the SSID. Disabling the SSID broadcast only hides the network name - the…

Explanation
Strong encryption (such as WPA2 or WPA3) is the best protection against unauthorized access because it requires a valid passphrase or credentials to decrypt and use the network, even if someone discovers the SSID. Disabling the SSID broadcast only hides the network name - the network is still detectable with wireless scanning tools and provides no real security barrier. Changing the default channel is a performance tweak, not a security measure. AP placement can limit the physical range of the signal but cannot reliably prevent a determined attacker from connecting if they are within range.
