Which three IP addresses can be assigned to hosts if the subnet mask is /27 and subnet zero is usable?
(Choose three.)
A. 10.15.32.17
B. 17.15.66.128
C. 66.55.128.1
D. 135.1.64.34
E. 129.33.192.192
F. 192.168.5.63
(Choose three.)
A. 10.15.32.17
B. 17.15.66.128
C. 66.55.128.1
D. 135.1.64.34
E. 129.33.192.192
F. 192.168.5.63
subnet mask is /27, 所以一个网段是2的5次方也就是32个,每个网段的第一个和最后一个IP是不能给host的,所以32的倍数和倍数减一是不能用的,这样128,192和63不可以,答案应该是ACD
