Wi-Fi Protected Access (WPA) operates at the data link layer because it is primarily concerned with securing wireless communication between devices on the same local area network (LAN). This layer is responsible for framing, addressing, and error detection, which WPA enhances by providing authentication and encryption protocols to protect data transmitted over wireless connections. By operating at this layer, WPA ensures that security measures are applied directly to the data being transmitted, safeguarding it from unauthorized access and tampering.

IEEE has divided the Transport layer into two sublayers?
No. It is the Data Link layer that IEEE has divided into two sublayers. The Data Link layers are Logical Link Control and Media Access Control.
