You work as the network administrator at TEC. The TEC network consists of a single Active Directory domain named
TEC. The TEC network contains 10 server computers, 500 portable client computers and 1,500 desktop client computers.
All servers on the TEC network run Windows Server 2003 and all client computers run Windows XP Professional. The
TEC network does not support remote access and is not connected to the Internet.
TEC users that are issued with portable client computers often work from home. When these users work from home, they
take their portable client computers home with them and connect it to their respective private home networks. You add a
new Windows Server 2003 server named TEC -SR11 on the TEC network. You install and enable the DHCP Server service
on TEC -SR11.
You configure all client computers on the TEC network to receive their IP configurations from DHCP when they are
connected to the corporate network. The next day several TEC users that are issued with portable client computers complain
that they are unable to connect to their respective private home networks.
You need to ensure that the portable client computers receive their IP configurations from DHCP when they are connected
to the corporate network and use static IP addresses when connected to the respective private home networks.

You work as the network administrator at Tec.com. The Tec.com network consists of a single Active Directory domain
named Tec.com. All servers on the Tec.com network run Windows Server 2003 and all client computers run Windows XP
Professional. A server named Tec-SR26 runs the DHCP Server service. A domain controller named Tec-DC01 runs the
DNS Server service. The Tec.com network consists of 3 subnets.
Tec-SR04 is a new file server on the Tec.com network. The Sales department users will use a shared folder named
CustomerInfo on Tec-SR04 to store confidential customer information.
Andy Booth works in the Sales department. Andy Booth and several other Sales department users complain that they cannot
access the CustomerInfo shared folder because they cannot connect to the file server.

2. Subnet B has a network ID of 192.123.88.32/27 and contains a domain controller and several client computers.
Several Sales users connect to the corporate network by using laptop computers. Only three Sales employees can connect to
the corporate network at any single point in time. You add several new client computers to the network. Shortly after this,
numerous users on each of the subnets complain that they cannot always connect to the corporate network.
You investigate the issue and find that users can connect to network after rebooting their computers later on in the day. You
also find that some users in each of the subnets have no problems connecting to the corporate network. On one of the new
client computers, you run the ipconfig utility to check its IP addressing configuration. The IP address of this computer is

You work as the network administrator at tec.com. The tec.com network consists of a single Active Directory domain
named tec.com that has two subnets named SubnetA and SubnetB. The two subnets are connected by a router. All servers
on the tec.com network run Windows Server 2003 and all client computers run Windows XP Professional. A server named
tec-SR25 runs the DHCP Server service.
All client computers are configured to receive theirIP configuration from DHCP and all servers are configured with static IP
addresses.
Due to the anticipated growth of the tec.com network over the next six months, you have been instructed to create a third
subnet named SubnetC on the network. You install the client computers on SubnetC and configure the client computers to
receive their IP configurations from DHCP.
You install a DHCP Relay Agent on SubnetC and connect SubnetC to a free port on the router. You then create a DHCP
scope of 192.168.3.1 - 192.168.3.254 with a subnet mask of255.255.255.0 on tec-SR25.
The new scope will be used for SubnetC. A few days later, management informs you that SubnetC must host 500 client
computers. You need to alter the scope for SubnetC so that it can support 500 client computers.
