以下は部分の問題と答えです。
1.Drag drop
You are the network administrator for a Web hosting company.All servers run Windows Server 2003. All
client computers run Windows XP Professional.
Your company is assigned the following IP address ranges by the ISP:
>131.107.10.0 through 131.107.10.255
>131.107.11.0 through 131.107.11.255
The company’s data center contains 400 Windows Server 2003 computers and consists of two subnets
named subnet A and subnet B.Subnet A contains 200 servers and uses the 131.107.10.0 network
address.Subnet B also contains 200 servers and uses the 131.107.11.0 network address.All server IP
addresses are assigned by DHCP.All computers in the data center have valid Internet-accessible IP
addresses.
As a result of a corporate acquisition, 200 additional servers will be added to your company’s data center
within one month.The new servers will be placed on the network segment that maps to subnet A.The
existing router does not have the capacity for an additional subnet, and the budget does not allow the
purchase of a new router.You will
need to add the additional servers to the existing subnet A.The ISP assigns you the additional IP address
range 131.107.12.0 through 131.107.12.255.
You need to change the IP addressing scheme to accommodate all required servers in subnet A and
subnet B.You are authorized to make any necessary changes.
The diagram in the work area shows the network configuration and the planned number of servers for
each subnet.
Which IP address should be assigned to each subnet?
To answer, drag the appropriate IP address or addresses to the correct locations in the work area.
IP address IP Addresses

2.You are the network administrator for your company.All servers run Windows Server 2003. All servers
are configured with static IP addresses.All client computers run Windows XP Professional.All client
computers are configured as DHCP clients.
The company has a main office and one branch office.The offices are separated by a router.A DHCP
server is deployed in each office.
One of the DHCP servers shuts down unexpectedly.It takes four hours to repair the server.During that
time, several mobile users connect their portable computers to the network and report that they cannot
connect to shared resources on the network.
After the server is repaired, you create a new scope on each DHCP server that includes IP addresses for
the other office.You activate the scopes.
You test the new DHCP configuration by shutting down the DHCP server in the main office.You find out
that the client computers in the main office are not receiving IP addresses from the DHCP server in the
branch office. You need to ensure that when the DHCP server in one office fails, the client computers will
receive a correct IP
address configuration from the DHCP server in the other office.
What are two possible ways to achieve this goal? (Each correct answer presents a complete
solution.Choose two.)
A.Configure the router between the offices to forward BOOTP broadcasts.
B.Configure the DHCP server in each office with a DHCP scope that includes the same IP addresses as
the DHCP server in the other office.Activate the scope.
C.Configure the DHCP server in each office with an additional network adapter.Connect each new
network adapter to the local network.Assign an IP address from the other office’s network to each new
network adapter.
D.Install and configure a DHCP relay agent in each office.
Answer: DA
3.You are the network administrator for your company.The network consists of a single Active Directory
domain.All servers run Windows Server 2003.
The network contains a Web server named Server1 that runs IIS 6.0 and hosts a secure Web site.The
Web site is accessible from the intranet, as well as from the Internet.All users must authenticate when
they connect to Server1.
All users on the Internet must use a secure protocol to connect to the Web site.Users on the intranet do
not need to use a secure protocol.
You need verify that all users are using a secure protocol to connect to Server1 from the Internet.
What are two possible ways to achieve this goal? (Each correct answer presents a complete
solution.Choose two.)
A.Monitor the events in the application log on Server1.
B.Monitor the events in the security log on Server1.
C.Monitor the Web server connections on Server1 by using a performance log.
D.Monitor network traffic to Server1 by using Network Monitor.
E.Monitor the IIS logs on Server1.
Answer: ED
4.You are the administrator of an Active Directory domain.All servers run Windows Server 2003. All client
computers run Windows XP Professional.All computers are members of the domain.
The Secure Server (Require Security) IPSec policy is assigned to a file server named Server6. The policy
is configured as shown in the exhibit.(Click the Exhibit button.)
http___pdftestpassport71
Users report that they cannot access shared folders on Server6. Users were able to access shared
folders on
Server6 prior to the implementation of the IPSec policy.
You need to ensure that all client computers in the domain can access the shared folders on Server6. You
must ensure that all communications between client computers and Server6 be encrypted.
What should you do?
A.On Server6, enable the All ICMP Traffic IP Security rule in the properties of the Secure Server (Require
Security) IPSec policy.
B.On Server6, enable the <Dynamic> IP Security rule in the properties of the Secure Server (Require
Security)
IPSec policy.
C.On all client computers, assign the Client (Respond Only) IPSec policy.
D.On all client computers, install an IPSec communication certificate in the local machine store.
Answer: C
