正确答案：A这个考的是思科SDN网络的基本概念。思科原文如下，请参考：
Fabric edge node: Equivalent of an access layer switch in a traditional campus LAN design.  Endpoints, IP phones, and
access points are directly connected to edge nodes.  
B：LISP是SD-WAN的概念，排除。
C：这个应该是说的broder leaf / broder node节点，连接其他的fabric或者传统网络三层节点。
D：这个应该说的underlay的路由协议（bgp/evpn等），提供fabric border 节点之间的可达性。
