why A wrong? For B, if we have 290 concurrent users which satisfy the question but still won't work

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.

Which action fixes the issue within the current resources? By changing the lease time, it doesn’t require an increase in resources

Selected Answer: B

This isn't rocket science. Each user only needs a DHCP IP for no longer than 2 hours. Currently, the lease time is 12 hours, so for an average of 10 hours IP addresses are tied up and not release back into the DHCP pool I would configure a lease time of 1-1.5 hour. If the client still needs an IP address, then they will be issued back the same IP it was originally using.

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

why not incresing the host portion? it will allow 510 host?

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.

The keywords in the question are: 1. 300 non-concurrent users 2. They connect only 2 hours per day So, decreasing the lease time definitely solves the problem. B is correct.

B is correct. DHCP server should release the addresses faster for the other clients.

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.
