Hello Chris
Indeed the WPA2 4-way handshake is not explicitly stated in the Cisco blueprint, however, in typical Cisco style, they always state a disclaimer of some sort that typically says that although these are the topics that are likely to be covered, there may still be others that are related that can also be included.
In any case, because the WPA2 4-way handshake is an integral part of how wireless networks securely operate, it has been included here to ensure that this process is understood. Although not explicitly stated in the blueprint, it may be a related topic that can be good to know.
As for the EAPOL 4-way handshake, yes that is indeed included, and you can find out more about it here:
I hope this has been helpful!
