Certified Ethical Hacker (CEH v10) — Question 187

A technician is resolving an issue where a computer is unable to connect to the Internet using a wireless access point. The computer is able to transfer files locally to other machines, but cannot successfully reach the Internet. When the technician examines the IP address and default gateway they are both on the
192.168.1.0/24. Which of the following has occurred?

Answer options

• A. The computer is not using a private IP address.
• B. The gateway is not routing to a public IP address.
• C. The gateway and the computer are not on the same network.
• D. The computer is using an invalid IP address.

Correct answer: B

Explanation

The correct answer is B because the computer's inability to access the Internet suggests that the gateway cannot connect to a public IP address, which is necessary for Internet access. Option A is incorrect since the computer is using a private IP address; option C is wrong because they are on the same network; and option D is not valid as the IP address is valid within the private range.
