Q: 9
You are tasked to configure the DHCP server to lease the last 100 usable IP addresses in subnet to. 1.4.0/23. Which of the following IP addresses could be teased as a result of the new configuration?

Option C saw something like this pop up on a practice exam too.
Option C, saw similar subnetting asked on a practice exam, matches last 100 range.
Option C, Definitely worth running some lab subnetting questions or using the official practice exam to nail this.
C/D? C is right for last 100, D looks good but that's the usual trap with subnet range questions.
C or D? I get why some might say D since it's close to the lower end, but pretty sure C is right if we count back the last 100 usable from the /23 block range. If someone spots a subnetting slip here, let me know.
B or D? I was sure you could pick B since it's the highest in the 10.1.4.x block, but maybe that's missing that 'last' means only .5.x addresses count. Not fully confident, maybe someone can explain why D wouldn't work.
Its C here. Had something like this in a mock and 10.1.5.200 was definitely inside the last 100 usable IPs for /23, starting from 10.1.5.155 up to .254. Pretty sure none of the others fit that DHCP pool.
Makes sense, definitely C. It's inside 10.1.5.155-254 so matches the last 100 usable range.
Probably C. 10.1.5.200 is within the last 100 usable addresses for the /23 subnet, just need to count back from 10.1.5.254. Option D tricks you because it's not high enough in that range, right? Correct me if I'm off.
It’s C, but man these subnetting questions never go away. 10.1.5.200 is in that last 100 range, rest are too low or wrong subnet.
