CompTIA A+ Core 1 (220-1101) — Question 47

A technician configured a new SOHO router for a small business. The ISP gave the technician an IP address on the router's WAN port. Which of the following addresses did the technician MOST likely configure on the router?

Answer options

• A. 10.1.50.30
• B. 19.45.7.28
• C. 169.254.168.10
• D. 172.22.40.6

Correct answer: B

Explanation

The correct answer is B, as it represents a public IP address assigned by an ISP. Options A and D are private IP addresses, which are not typically assigned to WAN ports, while option C is a link-local address, which is not suitable for WAN configuration.
