Exclamation DHCP Questions?

You are the administrator of a Windows 2000 Network. The Network currently has 60 clients computers configured as proxy clients. To dynamically manage IP addresses for these computers a DHCP server has been installed using a ascope of 172.41.64.0 the scope range 172.41.64.1 to 172.41.79.254 with a 20-bit mask has been configured. Users report that they cannot access information on any computer on the network. How can you correct this problem? (Choose 2)

A. Activate a scope
B. Authorize the DHCP Server
C. Change the scope range 172.41.64.1 - 172.41.79.255
D. Use a subnet mask of 255.255.193.0
E. Use a subnet mask of 255.255.248.0
F. Add a reservation for each of the client computers

What will be the answer?

Is there any additional information as other server numbers and gateways?
If not I would pick "A" & "C"

The answer given are A and D.
Why D?

20-bit mask
11111111.11111111.11110000.00000000
255.255.240.0

Why D?

Sorry i meant to write "D". "C" can't be used for in a scope you can't use 255 as a ranged number, has to be 1 or 2 less.

"D" is right. Is this question from a dump?

Why is D correct. Firstly there is no such thing as a 193 subnet mask, I presume you meant 192, secondly why wouldnt the original mask of 240 work in this situation. (multiples of 16)

How about A & B?
You have to authorize the server and activate the scope before the DHCP server can issue addresses. I've seen a question almost identical on transcenders.

Talking

I believe it is a and B also, You must activate a scope and authorize it in order for DHCP to issue IP addresses.

CandyKueh:

If this question was taken from a dump site, please be aware that they are well known for providing incorrect answers. I believe sometimes they do it just to throw people off track. This question covers one of the first things that you need to learn about DHCP, authorize the server and activate the scope. If you learn to pick apart the questions to see what is really being asked, you will see that this question is asking why the clients cannot access anything on the network. Your first "software" (don't forget the physical layer, too) troubleshooting should be to run ipconfig /all on one of the clients to see if it is getting an IP from the DHCP server, if not, next, make sure the DHCP server is authorized and activated. Hope this helps.

Exactly! The question states that:

Users report that they cannot access information on any computer on the network.

This is because the clients are not getting the correct IP configurations. And to correct this problem, first you have to make sure that your DHCP server is authorize and your scope is activated.
