| You are the administrator of your company's network. Your network consists of 2 subnets connected together with a BOOTP enabled router. (Subnet 1----Router----Subnet 2).
All clients are Windows 2000 Professional computers and Segement 1 has a Windows 2000 DHCP server on it. You have the DHCP server currently configured with a Scope for both subnets.
Every once in a while, users on subnet 2 call and report that the can't access network resources. You investigate and find out that during high times of network usage, client computers on subnet 2 receive an address in the 169.254.0.0 range. This is not a valid address range for your network.
You need to ensure that all client computers will receive addresses via DHCP and do not get configured with an invalid (with respect to your network) address.
What should you do? (Select "best" choice from the following).
If you know what 80/20 or 70/30 overlap is, I'm not even considering it here. This is just a basic question. 
A. Install a DHCP Relay agent on subnet 2.
B. Install a DHCP server on subnet 2 and configure identical scopes on each of the DHCP servers.
C. Edit the registry to disable APIPA on each of the client systems.
D. Install a DHCP server on subnet 2 and configure subnet specific scopes on each DHCP server.
Good luck. Have a nice weekend and we'll see you Monday for the answer!! | |

Well.... your no fun.  | |

| I will say C. | |

| I'll go with A | |
|
| Surly I will not go with A, the Router here support BOOTP. Please see Q 8
Also B and D are not best choice. | |
|
| Maybe I worded the question poorly.
Clients on subnet 2 are occasionally having issues obtaining an IP address via DHCP. When that happens, they get an APIPA address.
So how does disabling APIPA help ensure that a client will receive an IP address via DHCP? | |

| I don't think the question was worded poorly at all. The key phrase in this seems to be "You investigate and find out that during high times of network usage, client computers on subnet 2 receive an address in the 169.254.0.0 range." This leads me to believe that during off peak times, clients are able to receive an IP address. So it sounds like the server is running out of IP addresses and therefore the clients have to resort to APIPA. Disabling that would do nothing for the fact that they still can't obtain an IP address. Instead of 169.254.x.x they would be, I'm assuming, 0.0.0.0. The best option here would be to install another DHCP server on subnet 2 and configure subnet specific scopes on each of the servers.
The correct answer should be D. | |

| The answer in this case is D

In the real world I sense some bitterness..

| B and C do not help, A is not needed as they can get addresses normally
therefore D.
but in the real world . . . . . . | |

And the answer is....D
Slinky basically hit it right on the head. My comment about "real-world" was with respect to you probably wouldn't just configure a subnet specific scope on each DHCP server. You'd, in all likelihood, configure them with 2 scope in an 80/20 or 70/30 scope overlap scheme (For ex. - DHCP server on subnet 1 has a scope with 80% of the address range for subnet 1 and a scope with 20% of the address range for subnet 2. Vice versa for the DHCP server on subnet 2). You could also talk about Superscopes, but that is a little beyond the 210 material, you'll get plenty of that in 216  |
