Question 1

You administer your company's Windows 2003 domain. The domain contains 10 Windows Server 2003

computers, 750 Windows XP Professional computers, and 300 Windows NT 4.0 Workstation computers Four

of the Windows Server 2003 computers are DHCP servers, and two of the Windows Server 2003 computers

are DNS servers. All network computers are configured to use DHCP. All four DHCP servers are configured

with scopes for every subnet in the network.

You configure the DHCP servers to always register and update client computer information in DNS. To increase

security, you configure DNS to only allow secure updates.

Immediately following this, you discover that the resource records for the DHCP clients are no longer updated

when IP addresses change. You want the resource records for the client computers to have the most recent

information.

What should you do?

Options :

A : Add the computer accounts of the four DHCP servers to the DNSUpdateProxy global security group

B : Add the computer accounts of the two DNS servers to the DHCP Users domain local security group

C : Add the computer accounts of the four DHCP servers to the DNSAdmins domain local security group

D : Configure the four DHCP servers to enable updates for DNS client computers that do not support dynamic update. Configure the DHCP server to not release the DHCP lease for Windows XP Professional computers and the Windows NT 4.0 Workstation computers at shutdown. Configure the two DNS servers to use a Time to Live (TTL) interval on resource records that are shorter than the lease time used by the DHCP servers.

Answer: A

Question 2

Your corporate network uses variable length subnetting to make more efficient use of IP addresses. One of the IP addresses for a host is 131.39.161.17 with a subnet mask of 255.255.248.0. What is the proper notation for the network to which this host is connected?

Options :

A : 131.39.160.0/21

B : 131.36.161.0/20

C : 131.39.161.17/21

D : 131.36.160.0/20

Answer: A

Question 3

You work as the network administrator at ABC.com. The ABC.com network consists of a domain named

ABC.com. The servers at the ABC.com network run Windows Server 2003 and the workstations, Windows XP

Professional.

ABC.com has a Web server named ABC-SR10 which is connected to the Internet. During the course of the day

you have received instructions from the CIO to use System Monitor to determine how much bandwidth is used

on ABC-SR10's Internet connection. You decide to use the Bytes Total/sec counter with a sample rate of 10

seconds. You also plan to archive the logs once a day. Due to limited hard drive space, you need to prevent the

logs from getting too big.

What actions must you take to?

Options :

A : You should disable recursion

B : You should create a one-way initiated demand-dial connection.

C : You should configure an alert trigger when the Datagrams/sec counter is high

D : You should keep ABC-SR10 on the existing counter and set the sample rate to 60 seconds.

Answer: D

Question 4

There are several differences between IS-IS Hello packets used on broadcast interfaces and on pointto-point interfaces. Which of the following statements is FALSE?

Options :

A :

On broadcast interfaces there are different Hello packet types for level-1 and level-2 adjacencies, whereas on point-to-point interfaces there is a single Hello packet type.

B :

The multicast MAC addresses to which the Hello messages are sent are different on broadcast interfaces and on point-to-point interfaces.

C :

The neighbors are identified using their interface MAC addresses on broadcast Hello messages and using their system IDs on point-to-point Hello messages.

D :

Broadcast Hello messages identify the elected designed IS (DIS) and point-to-point Hello messages do not.

Answer: C

Question 5

Exam A

You work as It Admin at ABC.com. The ABC.com network consists of a domain named ABC.com. The servers

at the ABC.com network run Windows Server 2003. The ABC.com network has a file server named ABC-SR18.

ABC-SR18 hosts shared folders.

During your routine monitoring, you notice that ABC-SR18 has a connectivity issue. To investigate further you

run Network Monitor, but notices that during capturing, network packets were dropped.

What actions must you take to minimize the dropping of packets while monitoring ABC-SR18?

Options :

A : You should configure a persistent demand-dial connection

B : You should configure a two-way initiated demand-dial connection

C : You should use dedicated capture mode when utilizing the Network Monitor

D : You should select the Do not overwrite events option in the Event Viewer.

Answer: C
