To determine how many host bits are in the subnet mask 255.255.255.224, we first need to convert the subnet mask into binary form and count the number of bits used for the network and host portions.

The subnet mask 255.255.255.224 can be written in binary as follows:

  • 255 in binary is 11111111
  • 255 in binary is 11111111
  • 255 in binary is 11111111
  • 224 in binary is 11100000

Putting it all together, the binary representation of the subnet mask 255.255.255.224 is:

11111111.11111111.11111111.11100000

In this representation:

  • There are 27 bits set to 1 (the network portion).
  • The remaining bits (5 bits) are set to 0 (the host portion).

Therefore, the number of host bits in the subnet mask 255.255.255.224 is 5.

So, the correct answer is:

5.
