Certified Ethical Hacker (CEH v11) — Question 23

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 gateway must route traffic to a public IP address for Internet access, which it is not doing. Option A is incorrect as 192.168.x.x is a private IP address. Option C is also incorrect since both devices are indeed on the same subnet. Option D is wrong since the IP address is valid within the private range.
