While working on a Linux server, you're unable to connect to your Windows Server system across the internet. You're able to ping the default gateway on your own network, so you suspect that the problem lies outside of the local network. Which utility would you use to track the route a packet takes as it crosses the network? - ipconfig - ifconfig - traceroute - tracert

traceroute Explanation: traceroute is a Linux utility that allows you to track a packet's route as it traverses the network. The traceroute utility is used on Linux systems, while tracert is used on Windows systems. ipconfig and ifconfig are utilities used to obtain TCP/IP configuration on Windows and Linux systems, respectively.

You're troubleshooting an IP addressing problem and issue a command to view the system's TCP/IP configuration. The command you use produces the following output: fxp0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500inet6 fe80::2a0:83ff:fe30:57a%fxp0 prefixlen 64 scopeid 0x1inet 192.168.1.235 netmask 0xfffffc00 broadcast 255.255.255.255ether 00:a0:83:30:05:7amedia: Ethernet autoselect (100baseTX <full-duplex>)status: activelo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384inet6 ::1 prefixlen 128inet6 fe80::1%lo0 prefixlen 64 scopeid 0x7inet 127.0.0.1 netmask 0xff000000 Which of the following operating systems are you working on? - Linux - Windows Server 2019 - Windows Server 2022 - Windows 10

Linux Explanation: The output shown is from the ifconfig command run on a Linux system. Keep in mind that while you can still use ifconfig, the ip command has essentially replaced ifconfig as the Linux tool for configuring network adapters. The equivalent command on Windows 10, Windows 2019, and Windows Server 2022 is ipconfig.

While troubleshooting network connectivity at your office, you need to check the routing table. Which of the following commands could you use? (Select two.) - ping - ping6 - tracert - icmp - traceroute

- tracert - traceroute Explanation: Use the tracert (Windows) or traceroute (Mac) command to check the path to the problem network. The route command can be useful in troubleshooting. You can use the command on the router to view directly connected routes that have been set up. You can also use it on the default gateway of the local subnet to verify that the router has a route to the remote subnet. Additionally, you can use the route command to: View the routing table; this helps you see the networks the router knows about. Display additional networking information not provided by ifconfig. The icmp command sends an ICMP echo request/reply packet to a remote host. If you need to run the test on a network that uses IPv6, you need to add a -6 switch to the end, or you can just use the ping6 command.

When you enter a ping command at the command prompt how may echo packets are sent? - 5 - 4 - 3 - 6

4 Explanation: When you enter a ping command at the command prompt 4 echo packets are sent and 4 echo packets are received.

Which TCP/IP utility gives you the following output? - netstat -a - winipcfg - arp -a - ipconfig

ipconfig Explanation: The ipconfig command shows a computer's TCP/IP configuration information. winipcfg also shows the TCP/IP configuration, but it does so in a Windows graphical format. The arp -a command shows the current entries in a computer's ARP cache. netstat -a shows detailed information for active connections.

You've been called in to troubleshoot a connectivity problem on a newly installed Windows Server system. The system is operating well and is able to communicate with other systems on the local network. However, it's unable to access any systems on other segments of the corporate network. You suspect that the system's default gateway parameter hasn't been configured or may be configured incorrectly. Which of the following utilities are you MOST likely to use to view the system's default gateway information? - ipconfig - netstat - tcpdump - ifconfig

ipconfig Explanation: Use the ipconfig utility to view the TCP/IP configuration of a Windows Server system. The information displayed by ipconfig includes default gateway information. tcpdump is a packet analyzer that runs in a command line utility. Use the ifconfig command to view the TCP/IP configuration on a Linux, Unix, or Macintosh system. Keep in mind that while you can still use ifconfig, the ip command has essentially replaced ifconfig as the Linux tool for configuring network adapters. Use the netstat command to view TCP connection statistics.

You work in an office that uses Linux and Windows servers. The network uses the TCP/IP protocol. You're sitting at a workstation that uses Windows 10, but an application that you're using is unable to contact a Windows server named FileSrv2. Which command can you use to determine whether your computer can still contact the server? - nslookup - ping - arp - tracert

ping Explanation: On a TCP/IP-based network, you can use the ping command to check the connectivity between a source and destination computer. The arp command shows the IP address-to-MAC address mapping table (the address cache). The nslookup utility is used to perform manual DNS lookups on Windows. The tracert utility allows you to track a packet's route as it traverses the network.

Which TCP/IP utility gives you the following output? - ifconfig - ping - arp -a - ipconfig

ping Explanation: The output of the ping command shows you the results of four echo request/reply contacts with a destination host. The arp -a command shows the current entries in a computer's ARP cache. Use the ifconfig command to view the TCP/IP configuration on a Linux, Unix, or Macintosh system. Keep in mind that while you can still use ifconfig, the ip command has essentially replaced ifconfig as the Linux tool for configuring network adapters. Use the ipconfig utility to view the TCP/IP configuration of a Windows Server system.

Examine the following output: Reply from 64.78.193.84: bytes=32 time=86ms TTL=115Reply from 64.78.193.84: bytes=32 time=43ms TTL=115Reply from 64.78.193.84: bytes=32 time=44ms TTL=115Reply from 64.78.193.84: bytes=32 time=47ms TTL=115Reply from 64.78.193.84: bytes=32 time=44ms TTL=115Reply from 64.78.193.84: bytes=32 time=44ms TTL=115Reply from 64.78.193.84: bytes=32 time=73ms TTL=115Reply from 64.78.193.84: bytes=32 time=46ms TTL=115 Which of the following utilities produced this output? - tracert - ping - ifconfig - nslookup

ping Explanation: The output shown was produced by the ping utility. Specifically, the information output was created using the ping -t command. The -t switch causes packets to be sent to the remote host continuously until you stop it manually. ping is a useful tool for testing connectivity between devices on a network. Using the -t switch with ping can be useful in determining whether the network is congested. If it is, there will be sporadic failures in the ping stream. tracert is similar to ping in testing connectivity between two hosts on a network. The difference is that tracert reports information on all intermediate devices between the host system and the target system. ping, on the other hand, doesn't report information on intermediate devices. nslookup is a tool provided on Linux, Unix, and Windows systems that allows manual name resolution requests to be made to a DNS server. This is useful in troubleshooting name resolution problems. ifconfig is a tool for Unix, Linux, and Macintosh systems that is used to view the configuration of network interfaces, including TCP/IP network settings.

Which command should you use to verify that TCP/IP is correctly installed and configured on the local host? - ping 255.0.0.1 - ping 127.0.0.1 - ping 10.0.0.1 - ping 198.0.0.1

ping 127.0.0.1 Explanation: To verify that TCP/IP is correctly installed and configured on the local host use the following command: ping 127.0.0.1
