CompTIA A+ Core 1 (220-1101) — Question 430

A user purchased a retail router and would like to set up a private network. Which of the following network address ranges should the user configure?

Answer options

• A. 170.50.0.0 to 170.50.255.255
• B. 172.16.0.0 to 172.31.255.255
• C. 224.0.0.0 to 224.255.255.255
• D. 239.0.0.0 to 239.255.255.255

Correct answer: B

Explanation

The correct answer is B, as the range 172.16.0.0 to 172.31.255.255 is designated for private networks according to RFC 1918. Options A, C, and D represent public IP ranges or multicast addresses, which are not suitable for creating a private network.
