Networking with Windows Server 2016 — Question 105

Your company owns the public Internet IP address range of 131.107.20.0 to 131.107.20.255.
You need to create a subnet that supports four hosts. The solution must minimize the number of addresses available to the subnet.
Which subnet should you use?

Answer options

Correct answer: C

Explanation

The correct answer is C, 131.107.20.0/29, as it provides 8 addresses (6 usable), which is sufficient for 4 hosts while minimizing address waste. Option A (/28) offers 16 addresses (14 usable) and is more than needed. Option B (/30) only allows for 2 usable addresses, which is insufficient. Option D (255.255.255.224) has 30 addresses (28 usable), also exceeding the requirement.
