CompTIA Network+ (N10-008) — Question 761

A network technician is working to deploy a new subnet to support 500 hosts. The technician needs to limit the number of unused IP addresses. Which of the following subnets should the technician choose?

Answer options

• A. 255.255.224.0
• B. 255.255.248.0
• C. 255.255.252.0
• D. 255.255.254.0

Correct answer: D

Explanation

The correct answer is D (255.255.254.0), which provides 510 usable IP addresses, making it suitable for 500 hosts. Options A, B, and C offer more addresses than necessary, leading to higher numbers of unused IPs, which is not ideal for this scenario.
