Question:
You are working in a data center environment and are assigned the address range 10.188.31.0/23. You are asked to develop an IP addressing plan to allow the maximum number of subnets with as many as 30 hosts each. Which IP address range meets these requirements?
- 10.188.31.0/26
- 10.188.31.0/25
- 10.188.31.0/25
- 10.188.31.0/27
- 10.188.31.0/29
Explanation: Each subnet has 30 hosts < 32 = 25 so we need a subnet mask which has at least 5 bit 0s -> /27. Also the
question requires the maximum number of subnets (which minimum the number of hosts- per-subnet) so /27
is the best choice -> .
