| 1: | What is troubleshooting? |
| A1: | Answer: Troubleshooting is a systematic, step-by-step approach to isolating and testing components in a complex system. By testing components one at a time in a logical sequence, you can methodically isolate the cause of any given operating problem. |
| 2: | What command verifies that TCP/IP is configured correctly on your computer? |
| A2: | Answer: ipconfig is the tool to use to verify that your computer's copy of TCP/IP is configured properly. Of course, it helps to familiarize yourself with ipconfig and normal settings before trying to use it as a troubleshooting tool. |
| 3: | Which TCP/IP utility tests the reachability of any given Internet destination? |
| A3: | Answer: You can use two different tools to test the reachability of a destination on the Internet. Although both ping and tracert function similarly in this regard, ping was specifically built for that purpose. |
| 4: | Which tool determines if your computer's Ethernet connection is working properly? |
| A4: | Answer: netstat e is the specific command to run in a command prompt to see if your computer's Ethernet connection is working properly. Although it won't explicitly tell you if the connection is not working, you can surmise its status by examining the statistics that it presents. |
| 5: | Which tool determines if your computer's TCP/IP protocol suite is working effectively? |
| A5: | Answer: The best tool for evaluating your computer's TCP/IP protocol suite's operating efficiency is netstat s. That option shows you total volumes of data processed by both TCP and UDP and tracks send and receive data for ICMP messages. |
| 6: | How would you find out if the computer you are trying to access (or the network it is connected to) is experiencing heavy congestion? |
| A6: | Answer: If you run netstat s and see that your computer is receiving a large number of Source Quench messages, it is likely that whatever you were trying to do across the network was encountering congestion either at the network or host level. Either way, the message is clear: Slow down! |
| 7: | Which tool tracks the path your packets take through a network? |
| A7: | Answer: tracert or traceroute, depending on your computer's operating system, is quite useful in tracking the specific path that packets sent from your computer take to any given destination on a TCP/IP network. |
