Question 1. Under Windows NT, what command would you use if you wanted to trace a packet from its source host to a destination host?
The TRACERT utility is Microsoft's own, used to trace a packet from its source ( your computer ) to a destination host ( a remote computer ).
Question 2. If you wanted to display all entries in the ARP cache, which of the following utilities would you use?
A . ARP - G
B. ARP - E
C. ARP - D
D. ARP - S
To display all entries in the ARP ( Address Resolution Protocol ) cache, you would use the ARP utility with the -G or - A switch. They are the same thing. To get the answer type "arp /?" at the command prompt.
ARP ( Address Resolution Protocol ) is used to obtain hardware ( MAC = Media Access Control ) addresses for communications with a destination host.
Question 3. You notice that the subnet mask is 0.0.0.0 on your Windows NT computer while using the IPCONFIG utility at the command prompt to check for IP address configuration. What does it mean when the IPCONFIG utility displays a subnet mask of 0.0.0.0?
A. The default gateway on your computer does not match the default gateway of the network.
B. Your computer has the same subnet mask as another computer on the network.
C. Your computer does not have the correct IP address class specified for it.
D. Your computer has the same IP address as another computer on the network.
The most likely cause in this scenario is that your computer has the same IP address as another computer in the network. When this happens, running IPCONFIG will yield an IP address of 0.0.0.0.
Question 4. If you want to copy files from one Windows NT computer to another, what TCP / IP utility would you use?
A . RCP
The RCP ( Remote Copy ) is Microsoft's own TCP / IP utility. It is used to copy files from a source Windows NT computer to a destination ( remote ) Windows NT computer, or vice-versa. Type "rcp /?" at the command prompt to get the command's full syntax.
Question 5. Use the following diagram to answer this question :
You are working on your Windows NT workstation, SMALLNT, and you would like to communicate with another Windows NT computer, BIGNT. If both computers are on the same local subnet , where does SMALLNT look for the hardware address of the destination host? ( BIGNT in this case )
A. In its own ARP cache.
B. In the ARP cache of the destination host, BIGNT in this case.
C. If there is a DHCP server present , then in the ARP cache of the DHCP server.
D. In the LMHOSTS or HOSTS file of the source computer.
The ARP protocol ( and NOT the ARP command ) is used to map IP addresses to hardware addresses ( MAC addresses ). Anytime you communicate with a destination host that is on the same subnet ( locally ), then the hardware address of the destination host is obtained from the source host's LOCAL ARP cache. In this scenario, BIGNT's hardware address is obtained from SMALLNT's own ARP cache since both computers are on the same network.
Question 6. You have a print device connected to a server running the LPD service. From your Windows NT computer, you would like to obtain the status of the print device. What utility would you use to achieve the task?
B. NET USE
The LPD ( Line Printer Daemon ) is a TCP / IP printing service. A print server that has a TCP / IP print device connected to it must have the LPD service installed on it. However, to obtain the status of a TCP / IP print device ( or print queue as it is often called in the TCP / IP circle ), you would use the LPQ command.
Type "lpq /?" at the command prompt to get the proper syntax. Pay close attention to the "-S" and "-P" switches. For the "-S" switch, you can specify the NAME or IP address of the print server running the LPD service.
Question : Under Windows NT Server 4.0, how do you install the LPD service?
Answer : Under Windows NT, the LPD service is known as "Microsoft TCP / IP Printing" ===> right-click Network Neighborhood | Properties | Services tab | Add... | "Microsoft TCP / IP Printing" service.
Question 7. Let's say that you want to run a process on a remote host that is using the REXEC service, what Microsoft TCP / IP utility would you use?
The REXEC ( Remote Execute ) command is Microsoft's home-grown utility used to run processes on a remote computer that is also running the REXEC service. Type "rexec /?" at the command prompt to get the full syntax.
Question 8. If you want to retrieve system information from a remote host running the Finger service, what TCP / IP utility would you use?
The FINGER utility is used to obtain system information from a remote host that is using the Finger service. To get the proper syntax, type "finger" at the command prompt.
Question 9. Let's say that you want a DHCP client to give up its lease with a DHCP server, what command would you use to accomplish the task?
A. ipconfig / endlease
B. ipconfig / release
C. route / release
D. route / endlease
The IPCONFIG / RELEASE command is used to send a DHCPRELEASE message from a DHCP client to a DHCP server. The DHCPRELEASE message specifies that a client wishes to give up its current lease with the DHCP server. Type, "ipconfig /?" at the command prompt to display all the switches of the utility.
Question 10. You would like to see a list of NetBIOS computer names that have been resolved into IP addresses on your Windows NT computer. Which of the following utilities would you use?
You can use the "nbtstat" utitliy to view all NetBIOS computer names that have been resolved into IP addresses. To see the NetBIOS local name table of your workstation, use "nbtstat -n."
