思科CCNA考点逐个击破之IP&VLSM(2)自测考试有问题

今天自测“ 思科CCNA考点逐个击破之IP&VLSM(2)”只得了30分，感觉不对，仔细对了下正确答案，发现应该是答案有误，这是我在自测中发现错误最多的，有点误人子弟了！

第 1 题

Which of the following IP addresses fall into the CIDR block of 115.64.4.0/22? (Choose three.)

A. 115.64.8.32B. 115.64.7.64C. 115.64.6.255D. 115.64.3.255E. 115.64.5.128F. 115.64.12.128

答案是CEF，我认为应该是BCE，/22，只能是4-7。

第 2 题

Refer to the exhibit. All of the routers in the network are configured with the ip subnet-zero command.
Which network addresses should be used for Link A and Network A? (Choose two.)

A. Network A - 172.16.3.48/26B. Network A - 172.16.3.128/25C. Network A - 172.16.3.192/26D. Link A - 172.16.3.0/30E. Link A - 172.16.3.40/30F. Link A - 172.16.3.112/30

答案AD，我认为是BD，有120个主机，只有/25，128个地址的才能包括，而且只有后半个C才有128个IP。
