How many bits are borrowed from the default host portion of the address to create subnets in a Class B network with a subnet mask 255.255.255.0?

Question

Options

• A3 bits
• B5 bits
• C3 bits
• D8 bits

• A
  3% (1)
• B
  6% (2)
• C
  13% (4)
• D
  78% (25)

Explanation

In a Class B network, the default subnet mask is 255.255.0.0, which allocates: 16 bits for the network portion 16 bits for the host portion When the subnet mask is changed to 255.255.255.0, it becomes: 24 bits for the network portion 8 bits for the host portion This indicates that 8 bits have been borrowed from the host portion to create additional subnets. Borrowing bits allows for the division of the original network into smaller sub-networks, enhancing organization and security within the network.
