Computer Networks question 26
The network 192.168.5.0/24 must be divided into equal-sized subnets, each with at least 50 usable host addresses. What is the maximum number of such subnets?
- 2
- 4
- 8
- 5
Answer and explanation
Answer: B. 4
Explanation: A /26 subnet has 2^6 - 2 = 62 usable hosts (enough), while /27 has only 30. Going from /24 to /26 borrows 2 bits, giving 2^2 = 4 subnets.
