Questions & Step-by-Step Solutions

How many bits are borrowed from the host portion in a /24 subnet to create 4 subnets?
  • Step 1: Understand what a /24 subnet means. A /24 subnet has 24 bits for the network and 8 bits for the host.
  • Step 2: Identify how many subnets you need. In this case, we need 4 subnets.
  • Step 3: Use the formula 2^n = number of subnets, where n is the number of bits borrowed.
  • Step 4: Solve for n. We need 2^n = 4. This means n must be 2 because 2^2 = 4.
  • Step 5: Conclude that you need to borrow 2 bits from the host portion to create 4 subnets.
  • Subnetting – Understanding how to divide a network into smaller sub-networks by borrowing bits from the host portion.
  • Binary Exponentiation – Using powers of 2 to determine the number of subnets that can be created based on the number of bits borrowed.
