问题 In the implementation of VLSM techniques on a network using a single Class C IP address, which subnet mask is the most efficient for point-to-point serial links?
选项 A、255．255．255．0
B、255．255．255．240
C、255．255．255．248
D、255．255．255．252
E、255．255．255．254
答案D
解析 在点到点的链路上因为只需要分配两个地址给两端就可以了，所以加上网络地址和广播地址，这个网段也就只需要有4个地址了，所以网络位需要匹配30位,掩码就为255．255．255．252．
