1. You work as the network administrator at Alecnet .com. The Alecnet .com
network consists of a single Active Directory domain named Alecnet .com. All
servers on the Alecnet .com network run Windows Server 2003 and all client
computers run Windows 2000 Professional. The Alecnet .com network contains a
domain controller server named Alecnet -SR31 and a DNS server named
Alecnet -SR32. Alecnet -SR31 also provides DHCP services and file services.
You have received instruction to add a new server named Alecnet -SR33 to the
network as a member server in the Alecnet .com domain. You are also required to
configure Alecnet -SR33 to provide DHCP services instead of
Alecnet -SR31.
The DHCP scope configuration on Alecnet -SR31 is shown in the exhibit.
You want to prevent IP address conflicts and minimize network changes when
moving the DHCP service to Alecnet -SR33.
What should you do?
A. On Alecnet -SR33, create a new DHCP scope with a starting address of
192.168.0.20 and an ending address of 192.168.0.254.
Then deactivate the DHCP service on Alecnet -SR31 and authorize the DHCP
service on Alecnet -SR33. Finally, activate the new DHCP scope on
Alecnet -SR33.
B. On Alecnet -SR33, create a new DHCP scope with a starting address of
192.168.0.10 and an ending address of 192.168.0.254.
Then activate the new DHCP scope on Alecnet -SR33.
C. Back up the DHCP database on Alecnet -SR31 and stop the DHCP service on
Alecnet -SR31.
Then copy the backup file to Alecnet -SR33. Use the DHCP console on
Alecnet -SR33 to restore the DHCP service to Alecnet -SR33 and then authorize
DHCP services on Alecnet -SR33 and activate the DHCP scope.
D. Stop the DHCP service on Alecnet -SR31 and copy the DHCP database file on
Alecnet -SR31 to Alecnet -SR33. Then deactivate the DHCP service on
Alecnet -SR31 and authorize the DHCP service on Alecnet -SR33 and activate
the DHCP scope.

computers run Windows XP Professional. The Alecnet .com network contains two
domain controllers, four member servers and 500 client computers. The
Alecnet .com network contains a DNS server named Alecnet -SR20 and a
DHCP server named Alecnet -SR21. The network currently uses the network
address 192.168.0.0.
Alecnet .com hires 50 new employees. You have received instruction to add 50 new
client computers for the new employees. The new client computers must be added to
a new subnet with the network address 192.168.5.0. The router that will connect the
new subnet to the existing subnet is not capable of forwarding BOOTP traffic.
You enable the DHCP service on a server named Alecnet -SR22 and place it on

then add the new client computers to the 192.168.5.0 subnet and configure them as
DHCP clients. The relevant portion of this is shown in the network topology exhibit.
When you test the new configuration, you discover that the client computers named
Alecnet -WS291 and Alecnet -WS292 can ping other hosts on the
192.168.0.0 subnet but they cannot ping hosts on the 192.168.5.0 subnet. The client
computers named Alecnet -WS293 and Alecnet -WS294 can ping hosts on
the 192.168.5.0 subnet but not hosts on the 192.168.0.0 subnet.
You log on to Alecnet -WS293 and run the ipconfig command. You receive the

19. You work as the network administrator at Alecnet .com. The Alecnet .com
network consists of two subnets name Subnet A and Subnet B. Subnet A and Subnet
B are connected by a router. All servers on the Alecnet .com network run Windows
Server 2003 and all client computers run Windows XP Professional. All client
computers are located on Subnet
A. The server computers on Subnet B receive their
IP configurations from a DHCP server.
You add a new server named Alecnet -SR33 to Subnet B. However, when you
attempt to run Windows Update on Alecnet -SR33, you receive the following
error message: "Internet Explorer could not open the search page." You log on to
Alecnet -SR31 and run Windows Update successfully. You confirm that
Alecnet .com users on Subnet A can connect to Alecnet -SR33.
What should you do to run Windows Update on Alecnet -SR33?
A. Configure Alecnet -SR33 with a primary DNS server of 192.168.2.5.
B. Configure Alecnet -SR33 with a WINS server of 192.168.2.6.
C. Configure Alecnet -SR33 with a default gateway of 192.168.1.1.
D. Configure Internet Explorer on Alecnet -SR33 to use 192.168.1.1 as its proxy
server.

20. You work as the network administrator at Alecnet .com. The Alecnet .com
network consists of two subnets that are connected by a router. All client computers
on the Alecnet .com network run Windows XP Professional. Half the client
computers are portable computers and the rest are desktop computers.
The Alecnet .com domain contains a DHCP server named Alecnet -SR35. All
client computers receive their IP configurations from Alecnet -SR35. The
portable computers connect to either subnet during the day. The relevant portion of
the Alecnet .com network is shown in the exhibit.
A user named Mia Hamm has a portable computer named Alecnet -WS291.
Mia Hamm complains that when she connects to the 10.10.0.0 subnet, she receives
an error message indicating duplicate IP addresses. Other users of portable
computers are also experiencing similar problems. You log on to Alecnet -SR35
and examine the DHCP log file. You discover several Nack messages.
What is the most likely cause of this problem?
A. Alecnet -SR35 is not authorized in Active Directory.
B. The DHCP scope on Alecnet -SR35 is not activated.
C. The router is not capable of forwarding BOOTP traffic.
D. A Windows NT Server 4.0 DHCP server is on the network
E. A Windows Server 2003 DHCP server with workgroup membership and an activated
10.10.0.0 scope is on the network

21. You work as the network administrator at Alecnet .com. The Alecnet .com
network consists of a single Active Directory domain named Alecnet .com. All
servers on the Alecnet .com network run Windows Server 2003 and all client
computers run Windows XP Professional. The Alecnet .com network contains two
domain controllers, a member server named Alecnet -SR18, a file server named
Alecnet -SR19, and 500 client computers. Alecnet -SR19 hosts user files for
all Alecnet .com users.
Alecnet -SR19 suffers a catastrophic failure and is replaced with a new server
named Alecnet -SR21. You restore user files from a tape backup of
Alecnet -SR19 to Alecnet -SR21, and you create a logon script that maps
drive letters to shared files on Alecnet -SR21.
However, users complain that they cannot access Alecnet -SR21 through the
drive mappings you created and Alecnet -SR21 does not appear in their My
Network Places.
You log on to Alecnet -SR21 and confirm that the NTFS permissions and share
permissions are correct. You then run the ipconfig /all command on
Alecnet -SR21 and receive the following output.
What should you do to resolve the problem?
A. In the TCP/IP properties on Alecnet -SR21, add Alecnet .com to the DNS suffix
for this connection field.
B. In the TCP/IP properties on Alecnet -SR21, add IP address for the default
gateway.
C. In the TCP/IP properties on Alecnet -SR21, add IP address for DNS server
address.
D. Configure Alecnet -SR21 with a static IP address.
Answer: D |
22. You work as the network administrator at Alecnet .com. The Alecnet .com
network consists of two subnets name Subnet A and Subnet B. Subnet A and Subnet
B are connected by a router. All servers on the Alecnet .com network run Windows
Server 2003 and all client computers run Windows XP Professional. The
Alecnet .com network contains a member server named Alecnet -SR16. You
install the DHCP server services on Alecnet -SR16. The relevant portion of the
network is shown in the exhibit. You configure two scopes on Alecnet -SR16. One with an address range of
10.50.0.1 - 10.50.2.100/22 and an exclusion range of 10.50.0.1 - 10.50.0.20; and the
other with an address range of 10.60.0.1 - 10.60.2.100/22 and an exclusion range of
10.60.0.1 - 10.60.0.20. You activate the scope and configure client computers as
DHCP clients.
However, Alecnet .com users in both subnets report that they cannot access any of
the network servers. You log on to a client computer named Alecnet -WS291
and run the ipconfig command from a command prompt. You notice that
Alecnet -WS291 has been assigned the IP address of 169.254.9.24.
You verify that Alecnet -SR16 is connected to the network and is online. You
then log on to Alecnet -SR16 and run Network Monitor on for five minutes. You
capture hundreds of DHCPDISCOVER broadcasts.
What should you do to ensure that all client computers are able to access hosts on
both subnets?
A. Authorize Alecnet -SR16 in Active Directory.
B. Configure the router to forward UDP port 67 from 10.50.0.0 to 10.60.0.0.
C. Change the subnet masks on the DHCP scopes to 255.255.254.0.
D. Create a host (A) record for Alecnet -SR16 on the DNS server.
