CompTIA Network+ (N10-007) — Question 185

A network administrator needs to implement a new IP subnet containing 29 hosts. It is possible that the number of hosts in that subnet could eventually double.
The company only has a single, unused public IP network left to work with: 164.10.12.0/24. Which of the following would be the BEST way to divide this network without wasting addresses?

Answer options

Correct answer: C

Explanation

The correct answer is C, as a /26 subnet can support up to 62 hosts, which accommodates the current need of 29 hosts and allows for future expansion. Option A does not subdivide the network, while B and D offer insufficient capacity for both current and potential future needs.
