Answers to Questions 81-85 81. What utility provides you with current TCP/IP network connection statistics? A. IPstat B. SMNP C. ARP D. Netstat E. Nbtstat Explanation: Netstat displays protocol statistics and current TCP/IP network connection information. Some options used with the Netstat command allow you to see all connections, listening ports, Ethernet statistics, and routing table contents. & Domain 4.1: Given a troubleshooting scenario, select the appropriate TCP/IP utility from among the following: Tracert, ping, ARP, NBTstat, Netstat. IPconfig/Ifconfig, WinIPcfg, Nslookup.
82. Select the command line programs in NT that will reveal its routing. A. Ping B. TRACERT C. NETSTAT D. WINIPCFG Explanation: TRACERT is a form of Ping that times out at each hop (router) to report its status. ARP can reveal the conversion of the 32-bit IP address to the 48-bit Ethernet address. WINIPCFG is found only in Windows 9.x/ME. If you prefer the GUI style of WINIPCFG, you can find NT/Windows 2000 versions on the Resource Kit. & Domain 4.1: Given a troubleshooting scenario, select the appropriate TCP/IP utility from among the following: Tracert, ping, ARP, NBTstat, Netstat. IPconfig/Ifconfig, WinIPcfg, Nslookup.
83. What switch can be used with NETSTAT to view per-protocol statistics? A. Switch -s B. Switch -R C. Switch -S D. Switch -p E. Switch -r Explanation: You can always learn the various switches of commands and utilities by entering the help switch (/?) at the end of the command. For instance, from the command prompt type: NETSTAT /? to view the usage of each switch. & Domain 4.1: Given a troubleshooting scenario, select the appropriate TCP/IP utility from among the following: Tracert, ping, ARP, NBTstat, Netstat. IPconfig/Ifconfig, WinIPcfg, Nslookup
84. Which of the following commands displays per protocol statistics (case sensitive)? A. arp -S B. arp -s C. NBTSTAT -S D. NBTSTAT -s E. NETSTAT -s Explanation: You can view the various switches for each of the above utilities by using the accompanying help switch "/?", i.e. NETSTAT /?. & Domain 4.1: Given a troubleshooting scenario, select the appropriate TCP/IP utility from among the following: Tracert, ping, ARP, NBTstat, Netstat. IPconfig/Ifconfig, WinIPcfg, Nslookup.
85. What utility allows you to see active connections on a server? A. PING B. NETSTAT C. NBTSTAT D. TRACERT E. IPCONFIG Explanation: To find out what each utility can do, go to your DOS prompt and enter the utility followed by the "help" switch (/?), i.e. NETSTAT /?. This will explain all of the possible switches for the given utility. NBTSTAT shows NetBIOS over TCP/IP connections and statistics, while NETSTAT does not discriminate between connection types unless you tell it to. PING uses ICMP to determine connectivity to a given IP address. TRACERT uses ICMP to query the routers used between the sending and queried host, displays them, and return a DNS name for each if it can. IPCONFIG shows you the current IP configuration information on a Windows 2000/XP/NT machine. The switches differ between the different versions of the OS, but all of them respond to IPCONFIG /ALL and IPCONFIG /?. & Domain 4.1: Given a troubleshooting scenario, select the appropriate TCP/IP utility from among the following: Tracert, ping, ARP, Nbtstat, Netstat. IPconfig/Ifconfig, WinIPcfg, Nslookup.
