Question NO: 167
You are the administrator of windows 2000 network. The network consists of twoWo Windows 2000 Server
Computers named Servera and Serverb and 180 Windows 2000 Professional Computers on One Segment.
Servera Has An IP Address Of 192.168.2.1. Servera IS A DHCP Server. The TCP / IP Configuration Of All The THE
Windows 2000 Professional Computers Is Provided by The DHCP Server. The Range Of Addresses Used
AT Servera IS 192.168.2.0/24. The Lease Time Used IS 15 Days.
You want to change the ip address on the network from 192.168.2.0/24 to 10.17.8.0/24. Server B Has An
IP Address of 10. 17. 8. 1. You Install Another DHCP Server on The Server B. The Range of IP Address Used
By Serverb IS 10. 17. 8. 0/24. The Lease Time Used IS 15 Days.
The network is shown in the folload graph.
To Ensure Compatibility, The Two Address Ranges Will Be Concurrently On The Same Segment for Three
Monthings. Routing Between The Two Address Ranges is provided by a router on the network.
After You Activate The DHCP Scope on The Server B, Users Report That The same unable to iptain a valid ip
Address.
WHEN You Investigate The Problem you discover That Each of the Two DHCP Server Responded with DHCP
NEGATIVE ACKNACK. Messages to Leases Requested by The Client Computer.
What sales do to resolve the quprings?
A. ON A Windows 2000 Professional Computer, Disable Automatic Private IP Addresses (APIPA)
B. On The Windows 2000 Professional Computer, Configure The DHCP Client Computers To Release The
DHCP Lease At Shutdown
C. on Both DHCP Server Set The Number of Times SHOULD The DHCP Server Attempt Conflict Detection TO
ZERO.
D. On Both DHCP Servers Configure The Scope So That It has Both Address Ranges. Define An ExclusionRange for the entire address Range 10.17.8.0/24 on Server a and for the entire address range 192.168.
2.0 / 24 ON Server B.
E. ON Both DHCP Servers Set Scope Option 031. Perform Router Discovery To 1 To Enable The Option ON
Windows 2000 Professional Computes.
Answer: D
Explanation: It is not possible to have difference dhcp servers with limited same scopes on the same subnet. As in this
Scenario, They Would Send DHCPNACK RESPONSES To IP Requests Which Are Outside Their Own Scope.
The Solution Is To Replace The Two Scopes with a SuperScope Which Includes Both Scopes, and Use the superscope
On Both DHCP Servers. Precautions Must Be Taken To Prevent The Scopes To overlap. This is done by Exclusion
We Exclude The Entire Address Range of Both Scopes On Server B.
INCORRECT ANSWERS:
A: Disabling apipa wouldle prevent Clients from sale apipa addresses; instead they would get no
Configuration. this will not Solve The Problem with The Two Different Scopes.
B: The Release of IP Address Lease Is Not The Problem. The Problem is The Two Scopes on One Subnet.
C: setting the conflict detection to 0, Which is the default setting, The DHCP Servers Would Not Check if AN
IP Address Is Already in Use, Before Leasing It. The Two Scopes Are The Problem, Not Server Side Conflict
Detection.
E: Performance Router Discovery Is To Configure Routers, IT IS NOT A DHCP Scope Option.
