CompTIA Network+ (N10-009) — Question 459

A network technician needs to use a private Class A RFC1918 addressing scheme for user laptops on the company's network. Which of the following subnets should the technician choose?

Answer options

• A. 10.1.1.0/24
• B. 100.1.1.0/24
• C. 172.16.1.0/24
• D. 192.168.1.0/24

Correct answer: A

Explanation

The correct answer is A, as 10.1.1.0/24 falls within the Class A private IP range defined by RFC1918. Options B, C, and D are incorrect because 100.1.1.0 is a public IP address, while 172.16.1.0 and 192.168.1.0 belong to Class B and Class C private IP ranges respectively.
