1. Your goal is to monitor all your servers running Windows Server 2003 so that they can be defragmented on a regular schedule and as efficiently as possible. The disk

defragmentation program that you use requires at least 20% free disk space on each volume to defragment properly. What should you do

Configure Performance Logs And Alerts on a workstation (or less-used server) to monitor all the remote servers LogicalDisk object, % Free Space counter for each instance on that computer. In addition, configure each counter as an Alert with a threshold of Below 20% free space. Finally, configure each of the Alerts to send a message to the administrator (and any other user accounts that you want to receive the message).

2. You have been monitoring one of your servers running Windows Server 2003 due to poor performance on the network. The following data is representative of your findings:

Processor: % Processor Time: Physical Disk: % Disk Time: Memory: Pages/sec: Processor: Interrupts/sec: Process: % Processor Time (for nonservice processes): Process: % Processor Time (for system services):

It is likely that the Network Interface Card (or another device) is experiencing a problem at the device level. The high number of interrupts per second would cause the processor to be busy processing requests for service from the network interface. With all other counters being low, it is unlikely that an application or any System service is at fault.

3. The server that you are using to monitor the other servers on your network is overburdened with the task, so you must lighten its load of monitoring. To make the greatest impact for the monitoring computer s performance while maintaining as much monitored data as possible, what should you do

Increase the polling interval for recording the data from the remote computers. By decreasing the frequency of the data poll, and perhaps staggering the logging times, the greatest amount of monitoring data can be maintained while reducing the load on the monitoring computer.

Task Manager can provide processor, memory usage (including the page file), and basic I/O on a process-by-process basis.

2. Your computer crashes with almost clocklike predictability approximately one hour after each system startup. You suspect an application with a memory leak that is causing the system to run out of memory. How can you use Task Manager to determine which application is causing the problem

Start all applications normally. In Task Manager, select the Memory Usage Delta column (ViewSelect Columns) and click the column header. If you leave the system idle, then memory usage

by any of the processes running on the computer should stabilize. If there is an application with a memory leak, it should stay at or near the top of the list of processes running on the computer, and its value for Memory Usage Delta should continue to increase even with no activity on the system.

3. You are running a database application on your computer. Your computer has two processors. You want the database application to run on the second processor. How can you use Task Manager to do this

Right-click the database application in the Applications tab, and then choose Go To Process. Right-click the process, and set the processor affinity from the shortcut menu.

1. You need to get patch and hotfix information from a number of servers on your network. You would like to do this remotely. How can you use WMI to accomplish the task

Use the OS ASSOC alias with the /node: switch to run the WMIC command on any number of the computers remotely. Output to a CSV or HTML file for later use is possible as well using the /output alias and /format switch. For example, if Server01 and Server02 were the target computers for WMIC, the command would be /NODE:"SERVER01","SERVER02 OS ASSOC.

2. You want to get a list of all installed applications on 17 computers in the development department. You would like to do this remotely. How can you use WMI to accomplish this

Type the computer names into a text file (computers.txt, for example). Use the WMIC PRODUCT alias with the node/node:@ switch to get the list of installed applications on each of the computers in the list. Output to a CSV or HTML file for later use is possible as well, using the /output alias and /format switch. For example, /NODE:@c:\computers.txt PRODUCT would produce the desired results.

3. You want to give a small group of engineers the ability to use WMI to get information from some of the development servers, but you do not want to give them administrator privileges on the servers. What can you do to give the engineers access

Give each engineer, or a group of all engineers, permission to the WMI namespace, using WMI Control snap-in (Wmimgmt.msc) in the WMI MMC.
