Which statement about modern wireless security is accurate?

• A. WPA2/WPA3 with AES; PSK for simple deployments; Enterprise uses 802.1X with RADIUS; TKIP is deprecated.
• B. WPA2 uses RC4; PSK for enterprise only; 802.1X is not used; TKIP is mandatory.
• C. WPA3 prohibits AES; PSK is the only method; Enterprise is unsupported; TKIP is recommended.
• D. WPA2/WPA3 require open networks; PSK isn't used; AES is optional.

Answer: (A)

Modern wireless security relies on WPA2 or WPA3 using an AES-based cipher. For small, easier deployments you typically use a pre-shared key (WPA2-PSK or WPA3-SAE). In larger, enterprise environments, authentication is centralized with 802.1X and RADIUS, so each user or device gets unique credentials. TKIP is an older cipher that has known weaknesses and is being phased out in favor of AES-based CCMP/GCMP; WPA3 and current WPA2 configurations avoid relying on TKIP. Open networks provide no encryption, and AES isn’t optional in these modern standards. This combination—WPA2/WPA3 with AES, PSK for simple setups, 802.1X with RADIUS for enterprises, and TKIP deprecated—is the accurate portrayal.
