Answer: A
By borrowing 5 bits from the last octet, you can.
have 30 subnets. If you borrowed only 4 bits you could only
have 14 subnets. The formula is (2 to the power of n)-2.
By borrowing 4 bits, you have (2x2x2x2)-2=14. By borrowing
5 bits, you have (2x2x2x2x2)-2=30. To get 20 subnets, you
would need to borrow 5 bits so the subnet mask would be
255.255.255.248.
