第3题：
Your ISP has assigned you the following IP address and subnet mask:
IP address: 199.141.27.0
Subnet mask: 255.255.255.240
Which of the following addresses can be allocated to hosts on the resulting subnet?
(Select all that apply)

C. 199.141.27.13
D. 199.141.27.11
E. 199.141.27.208
F. 199.141.27.112
A,C,D 解析：Explanation:
IP address = 11001000.10001101.00011011.00000000 = 199.141.27.0
Subnet mask = 11111111.11111111.11111111.11110000 = 255.255.255.240
Subnet # = 11001000.10001101.00011011.00000000 = 199.141.27.0
Broadcast = 11001000.10001101.00011011.00001111 = 199.141.27.15
The valid IP address range = 199.141.27.1 - 199.141.27.14
