Exam 300-410 topic 1 question 167 discussion

I thought about this, but the last part of the question: "which action fixes the issue WITHIN THE CURRENT RESOURCES" gave the hint that we are not allowed to increase the address space. B is the best answer.

It always depends. Sometimes, like in a home network. A lease of 2 days is alright.

In here answers are change sorting, my mind is A or B in this question

ExamShark, this is all you say in very comment and NEVER once explain why you agree or add any value.

that would solve the problem only if we also alter the interface hosting the network, but theres no mention of altering that so I assume we go with the one that will still solve the issue without additional configurations.

the trick here is the number of 300 users, but it is not the real problem since they are not concurrent this means that they are not disputing leased IPs. The issue here is the lease time so it needs to be changed, that is why the answer is B.

That is wrong. You have a total of 203 IP addresses, and 300 clients. At the current configuration every Client up to the 203rd gets an IP, and occupies it for 12 hours (0 days 12 hours 0 minutes). So the 204th client per day fails to get an IP address. To fix this we need to lower the IP lease time from 12 hours down to somewhere around 2 hours as suggested in the question.
