4. Two routers configured to run BGP have been connected to a firewall, one on the inside interface and one on the outside interface. BGP has been configured so the two routers should peer, including the correct BGP ssion endpoint address and the correct BGP ssion hop-count limit (EBGP multihop). What is a good first test to e if BGP will work across the firewall?
有两个运行BGP的路由器连接到防火墙，一个在inside接口，一个在outside 接口。BGP 已经配置并且已经成为了邻居，包含正确的配置了BGP网络地址和正确的BGP跳数的限制（EBGP的多跳设置），怎么能够最好的测试BGP工作在防火墙上。
A. Attempt to TELNET from the router connected to the inside of the firewall to the router connected to the outside of the firewall. If telnet works, BGP will work, since telnet and B
GP both u TCP to transport data.
一亩地多少个平方
用在inside接口上的路由器telnet 到在outside 接口上的路由器。如果telnet 正常工作侧说明BGP能正常工作，因为telnet 和BGP 都是使用TCP 来传输数据的

a switch configured with the VTP mode "transparent"?
那一项最能说明，收到的ＶＴＰ信息是从透明模式的交换机收到的？

11. Refer to the exhibit. In this network, R1 has been configured to adverti a summary route,192.168.0.0/22, to R2. R2 has been configured to adverti a summary route, 192.168.0.0/21, to R1. Both routers have been configured to remove the discard route (the route to null created when a summary route is configured) by tting the dministrative distance of the discard route to 255. What will happen if R1 receives a packet destined to 192.168.3.1?

A. The packet will loop between R1 and R2.
这个包在R1和R2之间形成了环路
12. Refer to the exhibit. In this network, R1 is configured not to perform
auto-summarization within EIGRP.What routes will R3 learn from R2 through EIGRP?
如图所示，在这个网络中R1配置为在EIGRP中不做自动汇总，那么R3能从R2学到什么EIGRP 的路由信息。
A. 172.30.1.0/24 and 10.1.2.0/24; EIGRP only performs auto-summarization at the edge between two major networks.
172.30.1.0/24 和10.1.2.0/24 EIGRP在两个较大的网络边缘只能执行自动汇总。
13. The classic Spanning Tree Protocol (802.1D 1998) us which quence of variables to determine the best received BPDU?
