Question NO: 163
You are designing testking's new wan. The network consists of 50 Windows 2000 Server Computers,
2,500 Windows 2000 Professional Computers, 2,000 Windows 98 Computers and 50 UNIX Servers. The
Windows Environment Consists of A Single Windows 2000 Domain.
Users Store Data on Both of Their Client Computers and on The Server Computer Using Collaborative Object
Between Departments within the company.
The Physical Network Consists of Five Subnets Containing Computer and a Six Subnet Connecting To
Bootp routers as shown in the exhibit.
At Present It Is Not Necessary for Connectivity Within The Network. You Decide To Use the Reserve Network
IP address172.16.0.0. You are using dhcp to automatic or configure client computers TCP / IP
Configurations. The Server Computers Will Have TCP / IP STATILY Configured.
You want to accomplish the following goals:
• All Users Will Be Able To Access Resources Located on All Servers.
• All Users Will Be Able To Access Resources Available on All Client Computers.
• Network Traffic Between The Subnets Will Be minimized.
• The network will becomle to account for account growth fundh of up to 100 percent over the next year with the NEXT YEAR WITH
Minimum Reconfiguration of the Physical Infrastructure.
You Take The Following Actions:
• Place All Windows 2000 Server Computers on Subnet1.
• Place All UNIX Servers on subnet2.
• Distribute The Client Computers Evenly Across Subnet 3, SUBNET 4 and Subnet5.
• Install the DHCP Server Service On One of the Windows 2000 Server Computer and Configure A
Scope for Each Subnet Include for Each Subnet Inclusses Default Gateway and DNS Settings.
• Install and Configure DNS Server Service On One of the Windows 2000 Server Computer.
• Configure All Windows based Computers To Use DHCP. • Subnet The Network Addresses Placed by Using The Subnet Mask 255.255.248.0.
Which Result Or Results Do Shere Actions Produce? (Choose All That APPLY)
A. All Users Are Able To Access Resources Located on All Servers.
B. All Users Are Aable To Access Resources Located on All Client Computers.
C. NetWork Traffic Between Subnets is minimized.
D. The network isplay it to accommodate growth of up to 100% over the next year with the minimal
Reconfiguration of the Physical Infrastructure.

Answer: a
Explanation: The Routers Are Bootp-enabled Therefore The DHCP IP Configuration Traffic Will Pass THE
Routers and reach all clients. The IP Configuration INCLUDES CORRECT DNS AND DEFAULT GATEWAY SETTINGS. THIS IS
Done by Using A Different Scope for Each Subnet. Thase Clients Will Then Be Aable To Reach All Servers, Including
The UNIX Servers. All Servers Are Configured for TCP / IP.
INCORRECT ANSWERS:
B: All Clients Have Received Proper IP Configuration from The DHCP Server. However, The Windows 98
Clients Would Not Be Able To Register THEMSELVES IN The DNS ZONE. The Default Settings of the DHCP
Server Is Not to Update DHCP Client Information In DNS (this Is Not Required for Windows 2000 Clients
As The REGITER THEMSELVES. The Windows 98 Clients Would Not Be Accessible from the Other Computers.
WE WOULD HAVE TO Configure DHCP To Automatically Update DHCP Client Information In DNS (See
Picture below) to make this happen.
C: To Minimize Network Traffic You Should Install One DNS Server and One DHCP Server On Each Segment.
This Would Decrease Network Bandwidth Usage Since DNS AND DHCP Traffic Would Be Kept Local On Theubnet.
D: Currently There Are 4600 (50 2,500 2,000 50) Computers. And in a year it will double to 9200. NEED 14
Bits for Hosts (2 ** 13 = 8192 <9200 <16384 = 2 ** 14). SO Subnet Mask Will BE 18 BITS:
Required Subnet Mask, Binary: 11111111. 111111111.110000.00000000
Required Subnet Mask, DECIMAL: 255.255.192.0
The 21 Bits Subnet Mask, 255.255.248.0, Would Ion Allow 2 ** 11 = 2048 Hosts.
