Which statement about WPA2/WPA3 encryption is true?

• A. It helps protect data in transit by encrypting wireless communications.
• B. It is the same as hiding the SSID.
• C. It requires no passphrase.
• D. It slows network significantly without improving security.

Answer: (A)

WPA2 and WPA3 are Wi‑Fi security protocols that keep wireless traffic private by encrypting the data as it travels between devices and the access point. This means someone listening to the air cannot easily read what you’re sending or receiving, even if they can see the packets being transmitted. WPA3 adds further improvements to authentication and resistance to offline guessing, but the core idea remains: the data in transit is protected through encryption. Hiding the network name (the SSID) isn’t the same as encrypting traffic. It doesn’t reliably prevent discovery or protect the content of your communications, so it isn’t a substitute for WPA2/WPA3 security. In typical setups, these networks do require credentials to join—usually a passphrase for personal/PSK modes or user credentials in enterprise modes. As for performance, modern hardware handles the encryption with minimal impact on speed, so the security gains far outweigh any negligible overhead.
