今天（2008-10-09）上午接到E-Dream思科互助学习小组一成员杨同学的来电，说CCNA考试中有很多题棘手，所幸有惊无险，顺利通过了考试！在这里，我代表全体煮酒工作室成员及E-Dream思科互助学习小组表示祝贺！
思科CCNA考试有50多道题，这次他是54道。类型有选择题（主要），实验模拟配置题，实验拖图题，还有设备选用拖图及配置题，读题做多项题目的“一拖多”题，不过，大体上还是较为好做。对于新的学员，可能很想知道是什么样子的，这里，我贴上几道题：
1. Which wireless LAN design ensures that a mobile wireless client will not lose connectivity when moving from one access point to another?
A. using adapters and access points manufactured by the same company
B. overlapping the wireless cell coverage by at least 10%
C. configuring all access points to use the same channel
D. utilizing MAC address filtering to allow the client MAC address to authenticate with the surrounding APs
2.Refer to the exhibit. The Branch router displays knowledge of a route to network 172.16.0.0/16. The actual network number at headquarters is 172.16.1.0/24. Why does the network number appear as it does in the routing table?
A. The Branch router has a static route configured for the 172.16.0.0/16 network.
B. The routing protocol on the HQ router is using automatic route summarization.
C. The Branch router is configured to summarize to classful boundaries.
D. The routing protocol on the Branch router has been misconfigured.
