1. You administer a network in which
some of the employees occasionally work from home. One
of the employees, Jon, uses a portable Windows XP Professional
machine. At work, he connects to the network using a docking
station outfitted with a Network Interface Card (NIC).
At home, Jon connects to the network using a modem and
a dial-up connection to a Windows Server 2003 machine on
your network that has been configured with the Routing
and Remote Access Service (RRAS).
At work, he can connect to the network just fine, but
from home while he can connect to the RRAS server, he
cannot access any resources on the network.
The Networking tab of the Dial-up Connection Properties
sheet is shown for Jon's portable computer in the exhibit.
Which of the following actions should you take on Jon's
portable computer to enable Jon to access network resources
from home?
A. Disable Internet Protocol (TCP/IP).
B. Enable File and Printer Sharing for Microsoft Networks.
C. Enable the Client for Microsoft Networks.
D. Change the Type of dial-up server I am calling: option.
Answer: C
In order for Jon to access network resources from home,
the Client for Microsoft Networks must be enabled on
Jon's portable Windows XP Professional machine. Using
PPP for the Type of dial-up server I am calling: and
Internet Protocol (TCP/IP), will allow Jon to connect
to the RRAS server from home, but you must enable the
Client for Microsoft Networks to allow him access to
the rest of the network.
Disabling Internet Protocol (TCP/IP) would not enable
Jon to access network resources from home. On the contrary,
since TCP/IP is the only protocol available on Jon's
portable computer, disabling it would also prevent Jon
from accessing the network.
Enabling File and Printer Sharing for Microsoft Networks
would allow other users to access files on Jon's portable
Windows XP Professional machine, but will not enable
Jon to access the network.
In this scenario, changing the Type of dial-up server
I am calling: on Jon's portable computer would not enable
Jon to access network resources from home. Jon is not
having problems connecting to the RRAS server from home,
so this setting should not be changed.

2. You are the network administrator for Contoso, Ltd. The network consists
of a single Active Directory forest with two domains, contoso.com and
fabrikam.com. Fabrikam is a division of Contoso. All network servers
run Windows Server 2003. All client computers run Windows XP Professional.
Contoso has a primary DNS server named DNS1, located
in the London office. Fabrikam has a primary DNS server
named DNS2, located in the Amsterdam office. Each company
also has regional offices. Each regional office has a
secondary DNS server, a DHCP server, and an Internet
Security and Acceleration (ISA) server that connects
all computers on the LAN to the Internet.
Field engineers from Contoso report that they are unable
to access the Internet when they visit Fabrikam's offices.
You want to enable all field engineers access the Internet
when they visit Fabrikam's offices. You want to use the
least amount of administrative effort to accomplish your
objective.
What should you do?
A. In the Advanced TCP/IP Settings on the client computers,
configure the DNS suffix for this connection with the
name fabrikam.com.
B. In the Advanced TCP/IP Settings on the client computers, configure
the primary DNS suffix as fabrikam.com.
C. On the primary DNS server for fabrikam.com, add a _http_service service
locator (SRV) resource record for each ISA server in the domain.
D. On each DHCP server in the fabrikam.com domain, configure the 015
DNS Domain Name option as fabrikam.com.
Answer: D
The 015 DNS Domain Name option automatically sets the
DNS suffix for this connection. So, although A would
work, the easiest method for resolving the problem is
to let the local DHCP servers automatically assign the
correct configuration.

3. You are the network administrator for your company. All network servers
run Windows Server 2003 and all client computers run Windows XP Professional.
There are 150 servers, 50 printers and 2,000 clients on the same subnet.
You need to determine an IP addressing scheme for the subnet. You must
allow for future growth by using an IP addressing scheme that will allow
for 4,000 host addresses.
Identify the IP address range and subnet mask that you will use.
A. 10.0.0.1 through 10.0.15.255 with a 255.255.240.0/20 subnet mask.
B. 10.0.0.1 through 10.0.15.255 with a 255.255.255.0/24 subnet mask.
C. 10.0.0.1 through 10.0.15.255 with a 255.255.0.0/16 subnet mask.
D. 10.0.0.1 through 10.0.15.255 with a 255.255.252.0/22 subnet mask.
E. 10.0.0.1 through 10.0.15.255 with a 255.255.255.0/20 subnet mask.
Answer: A
You can use a 20-bit subnet mask of 255.255.240, which gives you 12
bits for the host address. That provides you with 4096-2 host addresses.

4. You are the network administrator for your company. All network servers
run Windows Server 2003 and all client computers run Windows XP Professional.
The network has three servers. You are planning to divide the network
into two subnets. Server1 is a domain controller and will have the IP
address 192.168.0.2. Server2 is a multihomed DNS server and will have
the addresses 192.168.0.1 and 192.168.1.1. Server3 is a DHCP server and
will have the address 192.168.1.2.
You need to configure the network so that all client computers can get
IP addresses from the DHCP server and connect to all network servers
and services. Due to budget limitations, you do not want to install more
network services than are absolutely necessary.
What will you do?
A. Install Server1 as an RRAS and DHCP server.
B. Install Server2 as an RRAS and DHCP server.
C. Install Server2 as an RRAS server. Install Server1 as a DHCP server.
D. Install Server2 as an RRAS server. Install Server2 as a DHCP relay
agent.
E. Install Server2 as an RRAS server. Install the DHCP relay agent on
subnet 192.168.0.0.
Answer: E
Since Server2 is a multihomed computer, you would install it as a Routing
and Remote Access (RRAS) server and use it as a router to connect the
two subnets. Since the 192.168.0.0 subnet does not have a local DHCP
server, you would need to install the DHCP relay agent on the local subnet
to forward DHCP requests and relay DHCP traffic by proxy.

5. The company you work for has a network of 500 computers, all on a single
network. The network IP address is 157.101.0.0 and you are currently using
the default subnet mask. There are five distinct divisions in your company
and you would like to divide the network into 5 subnets of 100 computers
each. You would like to leave room for one additional subnet in the future
and you want to keep the same network IP address.
Which of the following subnet could be apart of your planned network?
(Choose all that apply)
A. 157.101.64.0/18
B. 157.101.96.0/19
C. 157.101.160.0/19
D. 157.101.128.0/18
Answer: B, C
Both B and C are valid subnets in your planned network. Using the subnet
mask of 255.255.224.0 on your Class B network will give you a maximum
of 6 subnets with 8192 hosts each. The valid subnets under this mask
are 32, 64, 96, 128, 160, and 192.
Both A and D are valid subnets under the subnet mask of 255.255.192.0,
but they are the only subnets available. 2 subnets are insufficient for
your planned network.
