Certified Ethical Hacker (CEH v11) — Question 117

You are tasked to configure the DHCP server to lease the last 100 usable IP addresses in subnet 10.1.4.0/23.
Which of the following IP addresses could be leased as a result of the new configuration?

Answer options

• A. 10.1.255.200
• B. 10.1.4.156
• C. 10.1.4.254
• D. 10.1.5.200

Correct answer: D

Explanation

The correct answer is D, as 10.1.5.200 falls within the range of usable addresses for the subnet 10.1.4.0/23, which includes addresses from 10.1.4.1 to 10.1.5.254. The other options are either outside this range or are reserved addresses, making them unsuitable for leasing by the DHCP server.
