Answer:
The answer is "200.5.0.0 32/28".
Step-by-step explanation:
The requirement of the Bldg is =30.
The number of the host bits which is needed = 5
Therefore the subnet mask will be =/27
for bldg 3 netmask could be= /28
and when the /28 after that the last octet will be= 00100000.
00100000 converting value into a decimal value that is = 32.
therefore the correct value is 200.5.0.32 /28.
