1．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? (Choose two.)
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 dynamic routing protocol on CentralRouter to advertise summarized routes to InternetRouter.
F. a static, default route on CentralRouter that directs traffic to InternetRouter.
Answer: CF
解释一下：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。
2．What are some of the advantages of using a router to segment the network? (Choose two.)
A. Filtering can occur based on Layer 3 information.
B. Broadcasts are eliminated.
C. Routers generally cost less than switches.
D. Broadcasts are not forwarded across the router.
E. Adding a router to the network decreases latency.
