You manage a network that has multiple internal subnets. You connect a workstation to the 192.168.1.0/24
subnet
This workstation can communicate with some hosts on the private network, but not with other hosts. You run
ipconfig /all and see the following:
Ethernet adapter Local Area Connection:
Connection-specific DNS Suffix . : mydomain.local

Q

You administer a network with Windows 2000 and UNIX servers, and Windows 2000 Professional, Windows

98, and Macintosh clients. A user of a Windows 98 computer calls you one day and says he is unable to
access resources on the network. You type ipconfig on the user’s computer and receive the following output:

0 Ethernet adapter:

IP address. . . . . . . . . : 169.254.1.17
Subnet Mask . . . . . . . . : 255.255.0.0
Default Gateway

You also check your NIC and see the link light on.

What might the problem be?
Missing default gateway
The user changed the configuration of the computer
Misconfigured DNS server
Unavailable DHCP server

Q

You’re trying to access your office network with your Windows XP workstation from home using your
organization’s virtual private network (VPN).

Your modem has dialed and connected to your ISP, but you can’t connect to your office network. You issue

the ipconfig command from the shell prompt and learn that your system has been assigned an IP address of
169.254.1.12.

What’s causing the problem?

Your organization’s firewall is filtering VPN connections.

Your ISP’s DHCP server isn’t working properly.

Your modem doesn’t support the v.56 standard, which is needed for VPN access.

Your organization’s VPN is down.

Your ISP’s DNS server isn’t working properly.

A

Your ISP’s DHCP server isn’t working properly.

Q

Due to widespread network expansion, you have decided to upgrade the network by configuring a DHCP

server for the network. The network uses Linux, Windows, and Mac OS X client systems.

You configure the server to distribute IP addresses from 192.168.2.1 to address 192.168.2100. You use the
subnet mask of 255.255.255.0.

After making all setting changes on the DHCP server, you reboot each client system but they are not able to
obtain an IP address from the DHCP server.

Which of the following would explain the failure?

DHCP does not function in a heterogeneous computing environment.

192.168.x.x requires a class C subnet mask.

The clients must be configured to obtain IP addressing from a DHCP server.

The DHCP server must be rebooted.

DHCP does not work in a heterogeneous computing environment unless the DHCP samba client software
is installed.

A

The clients must be configured to obtain IP addressing from a DHCP server.

Q

Which of the following tools would you use to view the MAC addresses associated with IP addresses that the
local workstation has contacted recently?
