When setting up a wireless network, an administrator enters a pre-shared key for security. Which of the following is true?

In WPA/WPA2 Personal (and WPA3-SAE), the pre-shared key is a symmetric secret - the same value is configured on both the access point and every connecting client. This PSK is fed into a four-way handshake key derivation process to produce the Pairwise Transient Key (PTK), which is the actual symmetric key used to encrypt data transmitted over the wireless link.

The PSK is not a hash used for integrity checking - it is a secret input to a key derivation function that produces the encryption keys for the wireless session.

The PSK is a static, pre-configured symmetric secret and is not itself a Diffie-Hellman value - while WPA3-SAE uses a DH-based exchange internally, the PSK as entered by the administrator is a symmetric shared secret.

RSA is an asymmetric algorithm; wireless PSK-based security relies entirely on symmetric key cryptography, not RSA.
