4.10.7 practice questions Test out network

You're troubleshooting an IP addressing issue, and you 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 : 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 2016 is ipconfig.

Which TCP/IP utility gives you the following output? Reply from (ip address) Bytes(__) time (___ms) TTL 128 Reply from (ip address) Bytes(__) time (___ms) TTL 128 Reply from (ip address) Bytes(__) time (___ms) TTL 128

Ping : The output of the ping command shows you the results of four echo request/reply contacts with a destination host

Which TCP/IP utility gives you the following output?

netstat -r : shows you the computer's routing table.

Your computer is sharing information with a remote computer using the TCP/IP protocol. Suddenly, the connection stops working and appears to hang. Which command can you use to check the connection?

netstat : Use the netstat command to check the status of a TCP connection.

Which TCP/IP utility gives you the following output? Interface: 192.168.4.101 on Interface 0x3Internet Address Physical Address Type192.168.1.23 00-d1-b6-b7-c2-af dynamic

arp : This output is displayed when you use the arp -a command to look at the ARP cache.

Which of the following tools would you use to view the MAC addresses associated with IP addresses that the local workstation has contacted recently?

arp : Use the arp command to view the MAC addresses associated with IP addresses that the local workstation has contacted recently. When a workstation uses arp to find an IP address's MAC address, it places that information in its ARP table.

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 : Use the ipconfig utility to view the TCP/IP configuration of a Windows Server system. The information displayed by ipconfig includes default gateway information.

netstat : The output shown is produced by the netstat command. netstat reports the open TCP/IP ports on the local system, and it also identifies the protocol and remote host connected to that port. This information can be very useful when you're looking for security weaknesses, as a TCP/IP port that's open to traffic represents an unnecessary security risk.

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?

ping : 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.

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?

traceroute : 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.
