CompTIA Network+ (N10-009) — Question 227

A junior network technician at a large company needs to create networks from a Class C address with 14 hosts per subnet. Which of the following numbers of host bits is required?

Answer options

• A. One
• B. Two
• C. Three
• D. Four

Correct answer: D

Explanation

To accommodate 14 hosts per subnet, you need at least 4 host bits, as 2^4 - 2 = 14 (subtracting 2 for the network and broadcast addresses). Options A, B, and C do not provide enough host addresses, as 1, 2, or 3 host bits would only allow for 0, 2, and 6 usable hosts respectively.
