Implement and Manage a Windows Server 2003 Network Infrastructure

  BackBy Certification Magazine —

These practice test questions from MeasureUp are based on Microsoft's exam 70-291: Implementing, Managing and Maintaining a Microsoft Windows Server 2003 Network Infrastructure.

The audience for this exam includes individuals who manage a network infrastructure that consists of at least three physical locations and multiple Active Directory domain controllers.

Experience with configuring and managing network-related protocols and services such as these will help you prepare for this exam: Internet protocol (IP) addressing, classless inter-domain routing (CIDR), name resolution services, and routing and remote access.

To pass this exam, you should also be able to secure computers and networks and use tools such as Network Monitor, System Monitor and Event Viewer.

By passing exam 70-291, you earn the Microsoft Certified Professional (MCP) certification. You also earn credit toward these certifications:

Microsoft Certified Systems Administrator (MCSA) on Windows Server 2003
Microsoft Certified Systems Engineer (MCSE) on Windows Server 2003

Objective: Implementing, Managing, and Maintaining Routing and Remote Access.
SubObjective: Manage TCP/IP routing. Manage routing protocols.

Multiple answers, multiple choice.

You are the network administrator for your company. All servers are running Microsoft Windows Server 2003.

Several servers on the network have been configured as routers to connect multiple subnets. You have implemented Open Shortest Path First (OSPF) on the network. You manage Area1BR, which is a computer running Windows Server 2003 that is configured as an area border router (ABR). Area1BR is connected to Area 0.0.0.0 and to Area 1. For Area 1, Area1BR advertises the summarized route 172.31.0.0/18.

Which two Internet protocol (IP) addresses define subnets that you can include in Area1? (Choose two.)

A. 172.31.96.0/18
B. 172.31.160.0/18
C. 172.31.224.0/18
D. 172.31.128.0/18
E. 172.31.192.0/18

Answers:
D, E

Tutorial:
You can include the subnets 172.31.128.0/18 and 172.31.192.0/18 in Area1. With the routing protocol OSPF, an area consists of contiguous subnets that can be represented by using route summarization. The network prefix "/18" indicates that the first 18 bits represent the subnet identifiers (IDs). This includes the first two bits of the third octet. The subnets that can be defined in this octet are represented in binary notation as 00000000, 01000000, 10000000 and 11000000. In decimal notation, the value of the subnet ID in the third octet can be 0, 64, 128 or 192.

The address 172.31.96.0/18 represents a host on subnet 172.31.64.0.

The address 172.31.160.0/18 represents a host on subnet 172.31.128.0.

The address 172.31.224.0/18 represents a host on subnet 172.31.192.0.

Note that with classless inter-domain routing (CIDR), you can use the all zeroes and all ones subnets if the routers and hosts in your network support these subnets. Computers running Windows Server 2003, Windows 2000 Server, Windows 2000 Professional or Windows XP Professional support these subnets. Routing protocols used with CIDR advertise the subnet mask as well as the subnet identifier for each subnet rather than relying on the value in the first octet of an Internet protocol (IP) address to designate the subnet mask.

Objective: Maintaining a Network Infrastructure.
SubObjective: Monitor network traffic. Tools might include Network Monitor and System Monitor.

Multiple answers, multiple choice.

You are the network administrator for your organization. All servers are running Microsoft Windows Server 2003. Client computers are running Microsoft Windows XP Professional.

Users on the network report that AppSrv-01 is sometimes slow to respond. The server is running a business-critical application. You discover that there is an excessive amount of network traffic going to and coming from the server.

You want to monitor network traffic on AppSrv-01 by using Network Monitor. However, you do not want any captured data overwritten, and you only want to capture header information.

What should you do? (Each correct answer presents part of the solution. Choose two.)

A. Increase the size of the buffer.
B. Select the Prompt to Save Data option from the Options menu.
C. Configure a new capture filter.
D. Decrease the frame size setting.
E. Create a display filter.

Answers:
A, D

Tutorial:
By default, Network Monitor has a default buffer size of 1 MB. This means that after it collects 1 MB of data, it will begin to overwrite the trace. To prevent this from happening, you should edit the Buffer Settings and increase the buffer size.

You can capture just the headers that are sent by altering the Frame Size setting. This can be done by selecting Buffer Settings from the Capture menu. The default frame size is Full, which means it captures the entire frame.

You should not select the Prompt to Save Data option from the Options menu. This only determines whether or not Network Monitor will prompt you to save data when you close a Network Monitor window.

You should not create a capture filter. This determines the type of data that Network Monitor will capture.

You should not create a display filter. This is used to filter data after a capture has been completed. It does not impact what data is captured.

Objective: Implementing, Managing and Maintaining Network Security.
SubObjective: Install and configure software update infrastructure. Install and configure software update services.

Single answer, multiple choice.

You install Windows Server Update Services (WSUS) on a computer running Microsoft Windows 2003 Standard Edition. The update server is synchronizing from Microsoft Update as shown in the exhibit.

You need to modify the configuration settings for synchronization.

What must you do first?

A. Click Stop Synchronizing from the selections on the left.
B. Click Home in the banner at the top.
C. Click Updates in the banner at the top.
D. Click Options in the banner at the top.

Answer:
A

Tutorial:
The first thing you must do is click Stop Synchronizing. You cannot change the synchronization settings while synchronization is running. Synchronizing will halt when you click Stop Synchronizing, and the synchronization settings will be enabled. You can then change the settings and, if you want, restart synchronization.
