CCNA试题,
A national retail chain needs to design an IP addressing scheme to support a nationwide network.The
company needs a minimum of 300 sub-networks and a maximum of 50 host addresses per subnet.
Working with only one Class B address,which of the following subnet masks will support an appropriate
addressing scheme?(Choose two.)
A.255.255.255.0
B.255.255.255.128
C.255.255.252.0
D.255.255.255.224
E.255.255.255.192
F.255.255.248.0

全国零售连锁公司,需要设计为其制定一个IP寻址计划,需要300个子网,每个子网最大能支持50个主机地址,目前只有一个B类地址,问下面哪几个子网掩码符合要求.
首先要300个子网,那肯定最少要借主机位至少9位做网络位,既2的9次方可以分512个子网满足第一个要求,然后剩下32-16-9=7的主机位,有2的7次方的主机数量,既128-2=126个可用主机IP,也满主条件.因此掩码为25的满主条件.写成10进制为：255.255.255.128
同理,借10主机位为网络位,即2的10次方有1024个网络位,也符合,看看剩下的主机位,32-16-10=6,2的6次方主机位为64,也满足最大50主机位的要求.所以255.255.255.192也符合.
答案：BE
