Answer: A
The easiest way to calculate this is to subtract
255.255.255.248 (subnet mask) from 255.255.255.255, this
equals 7. Convert the address 201.222.5.121 to
binary--11001001 11011110 00000101 01111001. Convert the
mask 255.255.255.248 to binary--11111111 11111111 11111111
11111000. AND them together to get: 11001001 11011110
00000101 01111000 or 201.222.5.120. 201.222.5.120 is the
subnet address, add 7 to this address for 201.222.5.127 or
the broadcast address. 201.222.5.121 through 201.222.5.126
are the valid host addresses.
