问题 Refer to the exhibit． The network administrator requires easy configuration options and minimal routing protocol traffic． What two options provide adequate routing table information for traffic that passes between the two routers and satisfy the requests of the network administrator?
选项 A、a dynamic routing protocol on InternetRouter to advertise all routes to CentralRouter．
B、a dynamic routing protocol on InternetRouter to advertise summarized routes to CentralRouter．
C、a static route on InternetRouter to direct traffic that is destined for 172．16．0．0/16 to CentralRouter．
D、a dynamic routing protocol on CentralRouter to advertise all routes to InternetRouter．
E、a static, default route on CentralRouter that directs traffic to InternetRouter．
答案C,E
解析 因为在这个图中,internetRouter要访问内网 172．16．0．0/16只能通过路由器CentralRouter．所以只需要在InternetRouter上配置一条通过CentralRouter到达172．16．0．0/16的网段就可以了。同样内网要访问外部，也只能通过路由器InternetRouter才能到达，所以也可以在CentralRouter上配置一条缺省路由到外部。
