(Ex:350-001):

1. You are the administrator of a Windows 2000 network. The network consists of a Windows 2000-based DHCP server, two Windows 2000-based DNS servers, a Windows 2000-based Routing and Remote Access server, and 60 Windows 2000 Professional portable computers. The network is configured as shown in the exhibit. (Click the Exhibit button.)
The DHCP server has a scope that has an IP address range of 10.65.4.20 through 10.65.4.80 with subnet mask 255.255.255.0.
You want the portable computers to use the DNS server that has an IP address of 10.65.4.12 when they dial in to the Routing and Remote Access server. The Routing and Remote Access server gathers IP addresses from the DHCP server for distribution to the portable computers when the portable computers dial in.
You configure the DHCP scope so that it has an IP address of 10.65.4.12 for the DNS Servers scope option.
When users dial in to the network by using the portable computers, all portable computers receive the IP address of 10.65.4.13 for the DNS server.
How should you configure the network so that the portable computers will receive the IP address of 10.65.4.12 for the DNS server?
A. Configure the DHCP server to always register and update client computer information to contain the configured DNS server.
B. Configure the Routing and Remote Access server to use the LAN interface to obtain DHCP, DNS, and WINS addresses for dial-up client computers.
C. Configure the LAN interface of the Routing and Remote Access server to not use an IP address for the DNS server.
D. Enable the DHCP Relay Agent on the Internal interface of the Routing and Remote Access server.
?Configure the DHCP Relay Agent to use 10.65.4.1 as the IP address for the DHCP server.
Answer: D


2.You are the administrator of your company's network. The network consists of five subnets that are connected by a BOOTP relay-enabled router. There are 50 Windows 2000 Server computers and 1,000 Windows 2000 Professional client computers distributed approximately evenly across the five subnets. There are also 25 UNIX servers and 100 DHCP-enabled network printers on the network.
You want to accomplish the following goals:
?The correct assignment of IP addresses to each client computer on each subnet will be automated.
?Address conflicts between client computers and servers will be prevented.
?Correct scope options will be applied to each client computer on each subnet.
?Client computers that are not in use will be prevented from keeping an IP address for more than three days.
?Each network printer will always receive the same IP address.
You take the following actions:
?Install the DHCP Server
service on a Windows 2000 Server computer.
?Create five scopes, each containing the address range for a specific subnet.
?In the DHCP console, set optional client configurations in the Server Options container.
?Exclude the range of addresses in use by the network printers.
Which result or results do these actions produce? (Choose all that apply.)
A. The correct assignment of IP addresses to each client computer on each subnet is automated.
B. Address conflicts between client computers and servers are prevented.
C. Correct scope options are applied to each client computer on each subnet.
D. Client computers that are not in use are prevented from keeping an IP address for more than three days.
E. Each network printer always receives the same IP address.
Answer: A

3. You are the administrator of your company's network, which includes three subnets. Each subnet contains 200 Windows 2000 Professional computers and five Windows 2000 Server computers. One Windows 2000 Server computer on one subnet runs the DNS Server service. The DNS server is configured to allow dynamic updates. All computers on the network have static IP addresses.
You add two UNIX servers named IW1 and IW2 to the network. Both servers host identical content for your internal Web site.
When you try to access the internal Web site from your client computer, your Web browser displays this message: "Can't find server or DNS error."
However, when you enter the IP addresses of the two Web servers in your browser, you can view the Web site.
You need to ensure that you can access each internal Web server by its name. Which two actions should you perform? (Each correct answer presents part of the solution. Choose two.)
A. Add one A (host) record to the DNS server for IW1. Add another for IW2.
B. Add one CNAME (canonical name) record named WWW to the DNS server for IW1.
?Add another CNAME record named WWW for IW2.
C. Disable dynamic updates on the DNS server.
D. Run the ipconfig /flushdns command on your client computer.
E. Run the ipconfig /registerdns command on your client computer.
Answer: AD

4. You are the administrator of one standard primary DNS server and two standard secondary DNS servers in a Windows 2000 domain.
There are no other DNS servers on the network. The domain includes Windows 2000 Professional computers and Windows 98 computers.
The DNS zone for the Windows 2000 domain is configured to allow dynamic updates. All three DNS servers are located on domain controllers. You want client computers to be able to register with any DNS server.
What should you do?
A. Change the zone type of the DNS zone for the Windows 2000 domain on all three DNS servers to Active Directory Integrated.
B. Change the settings on the standard primary DNS server to notify the two standard secondary DNS servers when the zone is updated.
C. Change the settings on the standard primary DNS server to allow zone transfers to only the two standard secondary DNS servers.
D. Change the dynamic update option on the standard primary DNS server to allow only secure updates.
Answer: A

5. You are the administrator of your company's network.
Your company has a Windows 2000 domain installed.
You installed the DHCP Server service, but you did not configure it.
Andrew is an employee at your company who belongs only to the Domain User group. Andrew will be responsible for deciding where DHCP servers should be placed on the network. When Andrew tries to authorize his server, the server displays the following error message: "Access denied."
Andrew needs to have the ability to authorize only DHCP servers. What should you do?
A. Add Andrew to the Schema Admins group.
B. Add Andrew to the DHCP Administrators group.
C. Delegate Control to Andrew on the NetServices system container in Active Directory.
D. Delegate Control to Andrew on the Query-Policies system container in Active Directory.
Answer: C

6. You administer the network segment used by your company's sales department. This department employs 50 salespeople, who use portable computers. Each business day, a maximum of 25 salespeople work on-site.
The remaining salespeople work remotely.
Your network segment includes one DHCP server running Windows 2000 Server. All the portable computers are DHCP clients. The DHCP server is configured with the characteristics shown in the following table.
Your department hires 20 new salespeople and issues portable computers to them. The new salespeople will work on-site for several months, and then begin working remotely. However, none of these new users can connect to the network.
They receive an error message indicating that their computers cannot obtain IP addresses.
You need to enable the new salespeople to connect to the network. Your solution must prevent the connection problem from happening again.
Your solution must also avoid disrupting network communications for existing network users and minimize network traffic associated with DHCP.
What should you do?
A. Delete the existing IP address leases from the DHCP server.
?Increase the setting for conflict detection attempts to 3 .
?Decrease the lease duration to eight hours.
B. Decrease the lease duration to one day. Increase the setting for conflict detection attempts to 2 .
C. On the new salespeople's computers, run the ipconfig /release command and then the ipconfig /renew command.
D. Disable dynamic update of DNS records. Decrease the lease duration to eight hours.
?Run the ipconfig /renew command on the new salespeople's computers.
Answer: A

8. You are the administrator of the contoso.com domain. Your network environment consists of a main office and two branch offices. The branch offices are connected to the main office by 256-Kbps leased lines. You have a single DNS zone, and all DNS servers are located at the main office. All servers on your network are running Windows 2000 Server. Your network is not connected to the Internet.
