Question 1.
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?

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

Explanation: 
The CPU of ABC-SR18 runs on 80%, which indicates that there are not enough resources to the network Monitor. Running Network Monitor in dedicated capture mode frees resources on the computer for capturing data. This results in fewer frames being dropped. The capture statistics are not displayed or refreshed because the frames are copied to the capture buffer.

Question 2.
You work as the network administrator at ABC.com. The ABC.com network consists of a single Active Directory domain named ABC.com. The servers at the ABC.com network run Windows Server 2003 and the workstations, Windows XP Professional. The ABC.com network has a DNS server named ABC-SR03 that does name resolution for host on the Internet. ABC.com users complain that they do not get the correct site when trying to access Web site known to them.

What actions must you take to stop this from happening without disrupting production?

A. You should restart the DNS Server service.
B. You should select the Secure cache against pollution setting.
C. You should run the ipconfig/flushdns on ABC-SR03.
D. You should run the ipconfig/registerdns on ABC-SR03.

Answer: B

Explanation: 
When the Secure cache against pollution setting is disabled, all records received in response to DNS queries are cached. This is true even when the records do not match to a queried domain name. Enabling the Secure cache against pollution setting disables the ability to pollute the DNS cache with incorrect information, and spoof DNS queries. With Windows Server 2003 the default setting is that caches are secured against pollution. This will then prevent users that browse the Internet from being directed to the wrong websites.

Question 3.
You work as the network administrator at ABC.com. The ABC.com network has a domain named ABC.com. The servers at the ABC.com network run Windows Server 2003 and the workstations, Windows XP Professional. The ABC.com network has a server named ABC-SR10 that runs Windows Server Update Services (WSUS). During synchronization you notice that you cannot connect to the Windows Update servers, however, you can access to other Web site not residing in the intranet. 

What actions must you take to connect to the Windows Update servers?

A. You must run the ipconfig/registerdns.
B. You must configure the forwarders on ABC-SR10.
C. You must set the authentication to the proxy server in the WSUS settings.
D. You must run the gpupdate /force command on ABC-SR10.

Answer: C

Explanation: 
In the Software Update Services administration console, there is an option to configure your internet connection settings. These settings include proxy server settings. If you have a proxy server between the SUS server and the internet, you need to configure the proxy server settings in the SUS options.

Question 4.
You work as the network administrator at ABC.com. The ABC.com network has a domain named ABC.com. The servers at the ABC.com network run Windows Server 2003. ABC.com has a subsidiary named Test Labs, Inc. that has a domain named testlabs.com. The ABC.com network has a DNS server named ABC-SR05. ABC-SR05 acts as a secondary zone for testlabs.com

What actions must you take to track when the DNS server at Test Labs, Inc. sends notifications of modifications in the zone of testlabs.com to ABC-SR05?

A. You must run the gpresult command in verbose mode.
B. You must select debug logging and set the log to store Notification events on ABC- SR05.
C. You must run the secedit command in analysis mode.
D. You must configure a two-way initiated demand-dial connection.

Answer: B

Explanation: 
Debug logging is disabled by default and has to be enabled on ABC-SR05. Select the Log packets for debugging check box to configure Debug Logging. To receive useful debug logging information, you should select a Packet direction, a Transport protocol, and at least one more option. You can also specify the file path and name, and the maximum size for the log file. Enabling Debug Logging slows DNS server performance.

Question 5.
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. The ABC.com network has a Web server named ABC-SR11. During a routine monitoring you notice an increase in network traffic. Due to this you need to find out the MAC address of the workstation that initiated the transfers and the command that was used. However, you action must not effect ABC-SR11.

What actions must you take?

A. You must run the ipconfig/registerdns.
B. You must use the Netmon utility.
C. You must capture the IP traffic to ABC-SR11.
D. You must Enable Server Message Block (SMB) signing on all the workstations.

Answer: C

Explanation: 
Network Monitor tool allows you to capture data. The tool also allows you to identify its source from where it came from. The Network Monitor tool also allows you to analyze the content of the message. Use a Network Monitor capture filter to capture IP traffic from any computer to ABC-SR11, and apply the capture filter before capturing the data.

Question 6.
You work as the network administrator at ABC.com. The ABC.com network has a domain named ABC.com. The servers at the ABC.com network run Windows Server 2003. The ABC.com network has only one DNS server named ABC-SR11 that only hosts the zone for ABC.com. During the course of the day you have received complaints that the response time of the connections to other workstations is very poor.

What actions must you take to see if it is the DNS client traffic on ABC-SR11?

A. You must set up a log of the Total queries/sec and the DNS counters Dynamic updates/sec.
B. You must configure a Network Monitor capture filter.
C. You must run the gpresult command.
D. You must set up the Performance Logs and Alerts to note down the Physical-Disk object.

Answer: A

Explanation: 
The System Monitor utility is used to collect and measure the real-time performance data for a local or remote computer on the network. Through System Monitor, you can view current data or data from a log file. When you view current data, you are monitoring real-time activity. When you view data from a log file, you are importing a log file from a previous session. Using the System Monitor, you can generate statistics on the following types of information regarding DNS services:
AXFR requests (all-zone transfer requests), IXFR requests (incremental zone transfer requests), DNS server memory usage, Dynamic updates, DNS Notify events, Recursive queries, TCP and UDP statistics, WINS statistics and Zone transfer issues. Thus to find out where DNS client traffic is responsible for the slow speed at which computers connect within the ABC.com domain, then you should create a log of the Dynamic Updated/sec and the Total queries/sec given the fact that ABC-SR05 is the only DNS server in the domain.

Question 7.
You work as the network administrator at ABC.com. The ABC.com network has a domain named ABC.com. The servers at the ABC.com network run Windows Server 2003 and the workstations, Windows XP Professional. The ABC.com network has a Web server named ABC-SR10 that has the Internet Information Services (IIS) 6.0 installed. ABC-SR10 hosts a Web site that can be reached from the internal network and the Internet. The internal traffic at ABC.com needs authentication without a secure protocol to access the Web site; however Internet traffic needs to authenticate with a secure protocol.

What actions must you take to ensure that the all accesses to ABC-SR10 use a secure protocol?

A. You need to configure the log to capture Notification events.
B. You need to apply the hisecdc.inf predefined security template.
C. You need to monitor network traffic and IIS logs.
D. You need to apply a custom security template.

Answer: C

Explanation: 
To make sure that the users are using a secure protocol, you must use the Network Monitor. The Network Monitor allows you to capture frames directly from the network. As soon as the frames are captured it will display and filter captured frames. The Network Monitor also allows you to edit captured frames and transmit them on the network.

Question 8.
You work as the network administrator at ABC.com. The ABC.com network has a domain named ABC.com. The servers at the ABC.com network run Windows Server 2003 and the workstations, Windows XP Professional. The ABC.com network has two servers, named ABC-SR30 and ABC-SR31, which contain file with sensitive company information. You create a new OU named SenSrv and move ABC-SR30 and ABC-SR31 to the new OU. You then create a new GPO that and configure it to encrypt all network connections. You then link the GPO to the SenSrv OU.

How would you check to see if encrypted connections to ABC-SR30 and ABC-SR31 are taking place?

A. By opening the Resultant Set of Policy console.
B. By running the Microsoft Baseline Security Analyzer (MBSA).
C. By applying the hisecdc.inf predefined security template.
D. By opening the IP Security Monitor console.

Answer: D

Explanation: 
Administrators can use the IP Security Monitor tool to confirm whether IP Security (IPSec) communications are successfully secured. The tool can display the number of packets that have been sent over the Authentication Header (AH) or Encapsulating Security Payload (ESP) security protocols, and how many security associations and keys have been generated since the computer was last started. The IP Security Monitor is implemented as a Microsoft Management Console (MMC) snap-in on the Windows Server 2003 and Windows XP Professional operating systems. It includes enhancements that allow you to view details about an active IPSec policy, in addition to Quick Mode and Main Mode statistics, and active IPSec SAs. IP Security Monitor also enables you to search for specific Main Mode or Quick Mode filters.

Question 9.
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. The ABC.com network has a DNS server named ITCERTKEYS-SR03. ABC.com changes ISPs. Now you receive complaints that ABC.com users cannot connect to Web sites on the Internet by using the URL of the Web site. You configure your workstation with the DNS server address of the new ISP. You can now connect to Web sites by entering their URL in the browser.

How would you configure ABC-SR03 to allow all users to connect to Internet Web sites without causing connectivity problems on the internal network?

A. You need run the Oclist.exe command and the Security Configuration and Analysis console on  
    ABC-SR03.
B. You need to utilize the default root hints of ABC-SR03 and set up a forwarder to the new ISP.
C. You need run the Dcgpofix on ABC-SR03 and set up forwarding to the new ISP.
D. You need to disable recursion and run the Security Configuration and Analysis console on  
    ABC-SR03.

Answer: B

Explanation: 
Forwarders are used to inform DNS where to look for name resolution when not in the local DNS database. With Windows Server 2003 conditional forwarding, recursive query requests can be subject to different DNS forwarder servers based on the domain name queried. The root hints file (cache hints file) contains host information needed to resolve names external of the authoritative DNS domains. It holds names and addresses of root DNS servers which are normally located on the Internet. In this situation where your network is connected to the Internet, the root hints file should contain the addresses of the root DNS servers on the Internet. With the default installation of Windows Server 2003, DNS uses the root hints file. It is not necessary to configure forwarders to access the Internet. Even though it is recommended to configure forwarders to point to your external domain, root hints will function quite fine.

Question 10.
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?

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

Explanation: 
The function of the Network Interface Bytes Total/Sec counter is to measures the total number of bytes that are sent/ received from the network interface. You use less processor cycles when you reduce the sampling frequency.
