| hey guys. please don't flame me for this question (it may be from a BD - I can't tell with the amount of "practise questions" sites around) but i really would like to know, because i don't agree with the given answer
-----------------
Your network consists of 50 Windows 2000 Server computers, 2,500 Windows 2000 Professional computers, 3,000 Windows 98 computers and 50 UNIX servers. You have a single Windows 2000 domain. Users store data on their client computers and on the server. You have five subnets, and a sixth subnet connecting two BOOTP routers. You use DHCP to configure TCP/IP configurations.
You want to accomplish the following goals:
All users will be able to access resources on all servers.
All users will be able to access resources on all clients.
Network traffic between subnets will be minimized.
You must allow for 100 percent growth over the next year with minimal reconfiguration.
You take the following actions:
Place all Windows 2000 Servers on Subnet 1.
Place all UNIX servers on Subnet 2.
Distribute clients evenly across Subnets 3, 4, and 5.
Install the DHCP Server service on one of the Windows 2000 Servers, and configure a scope for each subnet.
Install and configure DNS Server service on one of the Windows 2000 Servers.
Configure all Windows-based computers to use DHCP.
Subnet the network address space by using 255.255.248.0.
Which results do these actions produce? (choose all that apply)
A. All users will be able to access resources on all servers.
B. All users will be able to access resources on all clients.
C. Network traffic between subnets will be minimized.
D. You must allow for 100 percent growth over the next year with minimal reconfiguration.
----------
I think its B and D. B for obvious reasons, and D because 255.255.248.0 supports 6 subnets and 2046 hosts per subnet (if my calculations are right). But the answer says its just B
What do you think ppl? I'm probably going to sit this exam on saturday | |

| If you put all your clients on three /21 subnets (255.255.248.0) there will be:
a) Haven't thought about it hard enough to shoot this one down. The wording about the routers is not clear enough to conclude that all the nets are routed or not, but I think this is the key to this one.
c) Since the clients and the servers are all on different subnets and will access data on both servers and clients, network traffic between subnets will not be minimalized.
d) An issue with the 100% growth thing. 3x2048=6138 addresses. 5500x2=11000 clients.
Best of luck on your exam. | |

| bugger... i wasnt counting the 3000 win98 clients... well D would work if it was just the 2500 win2k clients... oops  | |

| As you are working up to get ready for an exam, you are reading so much documentation and so many questions, it is easy to miss something trivial that changes the whole outcome. I get that way when I am getting ready. Remember on exam day, take each question one at a time. You'll do fine. | |

what about relay agent in that scinario, as you configure dhcp server in one of your subnet, how can clients in the other subnets can get there ip configuration, as we have no information about routers bootp support here?
what do you think? |
