DHCP Question...

Forgive my ignorance...
A interviewer asked me today: What is DHCP? I told him...it issues IP addresses to clients/workstations/whatever. He said "what else?" Honestly, I don't know.
So...what else?

Pfft. I thought that was common sense. I just made myself look like a complete newbie.

Anything else probably would have sufficed - lease times, pools, servers/routers, what the acronym stands for, any problem you've experienced w/ it in the past. The easiest thing would have been to simply contrast it w/ static addressing and then describe the advantages and disadvantages of DHCP - which honestly was probably the meat of what they were looking for.
That being said, not going in depth w/ that one question probably wasn't too big of a deal.
Edit: And as Asif alluded to, you could have described what type of info DHCP configures. It's main purpose is to dole out IP addresses, but it also gives out other info, such as the subnet mask, default gateway, DNS server, etc.

When I perform technical interviews, I always present people a problem, and ask them to work through the problem. The goal is that I want to hear what tools they would use to work through a problem.
For example, in the support roles, one of the worst DHCP problems that we used to see was rogue DHCP servers (people bringing in home wifi routers to increase port density) These would start issuing DHCP addresses and if you have a large flat network, it can be a nightmare to track down the device.
During an interview one time, I got a technical question that was phrased like this: "One of the domains in our environment has a AD-DS server that is also a role holder and the role holder has crashed, what would you do to restore the server"
I answered it by saying the most important part is to restore service, so seize the roles in question on a new DC and once the DC is determined down, work through the problem on the server.
I was told that was the wrong answer and that I needed to work through the problem to resolve the server boot issue and users were impacted until we repaired the server.
I told him that was a poor infrastructure design. Safe it to say that 2 days later i received a call that I wasn't an ideal candidate.
My understanding is that your answer is/was wrong because after seizing FSMO you can't re-add the server: you have to rebuild it. Sometimes this is the way to go, sometimes not. I think the answer the interviewer wanted to hear was something about directory services restore mode or documentation/drivers, offline event logs, crash **** analysis, hardware troubleshooting, backups, etc.
You are correct - except that MS does have a way to do a recovery...

Neat.
With SBS, however, oftentimes the DC has other roles and services. Like file share and Exchange.
I agree that best practice design is to have more than one DC.
