WPA, WPA2, and WPA3 use what type of keys?

• A. Static
• B. Dynamic
• C. Hybrid
• D. Rotating

Answer: (B)

In WPA family security, the keys used to protect data are created for each session and refreshed as connections are established or re-keyed. The system starts with a master key derived from the pre-shared key (a password you set) and the network name, but the actual encryption keys that protect data traffic—known as the Pairwise Transient Key (PTK) for unicast and the Group Temporal Key (GTK) for multicast—are generated anew during the handshake and can change as devices associate, roam, or renegotiate. This means the encryption keys aren’t fixed forever; they’re dynamic and session-specific, which is what keeps the protection strong as channels open and close.

Static would imply a single, unchanging key across the network, which isn’t how WPA encrypts traffic. Rotating might sound similar, but the standard mechanism is that keys are derived and renewed as part of the handshake for each session, making dynamic the most precise description. Hybrid isn’t applicable here because the system doesn’t rely on a fixed-hybrid key approach.
