Answer / guest

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.
