According to the Huawei documents and resources, EAP termination and EAP relay are typical 802.1X authentication modes between the access device and authentication server. In EAP termination mode, the access device terminates EAP packets and encapsulates them into RADIUS packets. In EAP relay mode, the access device directly encapsulates the received EAP packets into RADIUS using EAP over RADIUS (EAPoR) packets2. Therefore, A and B are the correct answers.

 In a multicast solution, there must be reachable unicast routes between multicast sources and receivers, because multicast routing protocols use unicast routing information to build multicast forwarding trees.
