Question
### Question 2 #### Subnetting and Hosts Calculation If we have a subnet address as 212.10.22.0/24, how many hosts could we have in this subnet at most? **Options:** - **A. 1024** - **B. 256** - **C. 512** - **D. 128** ### Explanation This question focuses on calculating the number of hosts that can be accommodated within a given subnet. In this scenario, the subnet address is 212.10.22.0 with a subnet mask of /24. When the subnet mask is /24, it implies there are 24 bits in the network portion and the remaining 8 bits (32-24=8) in the host portion. Using the formula \(2^n - 2\), where \(n\) is the number of bits for hosts: \[ 2^8 - 2 = 256 - 2 = 254 \] Thus, a /24 subnet can have a maximum of 254 hosts (excluding the network and broadcast addresses). **Correct Answer: B**
