______ has up to 32,768 Available Subnets.

• A. Class A
• B. Class C
• C. Class D
• D. Class B

Answer: (D)

Subnetting works by borrowing bits from the host portion of an IP address to form separate networks. The number of subnets you can create depends on how many host bits you convert into subnet bits.

A Class B address has a default mask of 255.255.0.0, which leaves 16 bits for hosts. If you borrow 15 of those bits for subnets, you’re left with 1 bit for hosts in each subnet. That gives 2^15 = 32,768 subnets per Class B network.

So the statement that there can be up to 32,768 available subnets corresponds to Class B. By comparison, Class C has only 8 host bits (maximum subnets with at least one host bit would be 2^7 = 128), and Class A has many more possible subnets due to its 24 host bits.
