Explanation

WPA2 (Wi-Fi Protected Access 2) is a wireless security protocol - meaning it handles both authentication and encryption end-to-end, which is what actually controls which devices are allowed to join a network. It uses a handshake process to verify credentials before granting access, directly addressing the problem of unauthorized connections.

The distractors are all cryptographic algorithms, not wireless access protocols:

• RSA is a public-key algorithm used for encryption and digital signatures in contexts like TLS/HTTPS - it has no wireless-specific authentication role.
• AES (Advanced Encryption Standard) is actually the encryption cipher used inside WPA2, but by itself it only encrypts data - it doesn't control who can connect.
• DES (Data Encryption Standard) is an older, now-broken symmetric cipher, also irrelevant to wireless access control.

Memory tip: The key word in the question is "connecting" - WPA2 contains "Access" in its name (Wi-Fi Protected Access), signaling it governs access to the network. If a choice sounds like a standalone cipher (RSA, AES, DES), it can't be the answer to a question about preventing connections.
