Robust Security Network (RSN) works as a protocol for establishing secure communications over an 802.11 network. Choose the appropriate steps in the correct order to establish the communication.

A.

Explanation:
Robust Security Network (RSN) is a protocol for establishing secure communications between wireless clients and wireless access points (WAPs). It is a part of the 802.11i standard. The RSN protocol functions are as follows:
The wireless client sends a probe request frame.
As a response, the wireless access point (WAP) sends a probe response frame with an RSN information exchange (IE) frame.
Now, the wireless client requests for authentication and sends an association request frame. As a response, the wireless access point (WAP) sends an association response frame.
What is RSN?
Robust Security Network (RSN) is an element of 802.11i authentication and encryption algorithms to be used for communications between WAPs and wireless clients. It works as a protocol. It is used for establishing secure communications over an 802.11 wireless network.
