10.You are running Windows NT Server 4.0 Network monitor on the Windows NT Server computer that functions as the DNS,DHCP,and WINS server for the network. All computers on the network use TCP/IP with DHCP,DNS,and WINS.You capture 1,200 packets.  

How should you configure the display filter to view only the packets pertaining to the assignment of IP addresses?  

A. Protocol==SMB  
B. Protocol==DHCP

11.You are administrratoor of a Windows NT Server computer named Techs.Techs has an intel Pentium 133-MHz processor,32 MB of RAM,and 2-GB  SCSI hard disk.Techs functions as a file-and-print server for 115 client computers.  

Users of client computers have recently started reporting slow reponse times when they access files located on Techs.You run Performance Monitor and gather the following average statistics.  

　 Computer://TECHS  
　　　Object:Processor　　　　　　　　o  
　　　 %Processor Time　　　　　 80.835  
　　　Object:Memory  
　　　 Pages/sec　　　　　　　　101.155  
　　　Object:Server  
　　　 Bytes Total/sec　　　　84364.461  
　　　Object:PhysicalDisk　　　　　　 o  
　　　　%disk Time　　　　　　　100.000  

What should you do Techs to provider the greatest increase in performance?  

A. Upgrade the processor.  
B. Upgrade RAM to 64 MB  
C. Upgrade Techs to a multiprocessor system.  
D. Implement a stripe set with parity.  
b  
12.you are using an accounting application to print checks.The printer jams in the middle of the print job.The accounting application will allow you to reprint the checks.You turn off the printer and clear the jammed checks.

13.Your Windows NT Server computer is configure with six SCSI hard disks.One hard disk is the system disk,and the other five are configured as a stripe set with parity.  

After a power outage,your server reboots,and you discover that two of the five hard disks in the stripe set wiyh parity have failed.You replace both failed hard disks.  

What else should you do to recover from the hard disk failure?  

A.Regenerate the stripe set with parity by using Disk Administrator.  
B.Wait for Windows Nt server to regenerate the stripe set with parity.  
C.Create a stripe set across all five hard disks,and then restore from tape bacpup.  
D.Create a stripe set with parity across all five disks,and then restore from tape backup.  

d
