What command displays the IP address, subnet mask, and default gateway of the system you are currently on?
- A.
Ipconfig
- B.
Ping
- C.
Tracert
- D.
Nslookup
Correct Answer
A. IpconfigExplanation
The ipconfig command is used to display the IP address, subnet mask, and default gateway of the system you are currently on. It is a command-line tool that provides network configuration information for all network interfaces on the system. By running ipconfig, you can easily view important network details such as the IP address assigned to your system, the subnet mask that determines the network range, and the default gateway that serves as the access point to other networks.Rate this question:

What protocol does the ping command use to test network connectivity?
- A.
TCP
- B.
UDP
- C.
ICMP
- D.
FTP
Correct Answer
C. ICMPExplanation
The ping command uses ICMP (Internet Control Message Protocol) to test network connectivity. ICMP is a network protocol that allows devices to send error messages and operational information about network conditions. Ping sends ICMP echo request packets to a specific IP address and waits for an ICMP echo reply to determine if the network connection is working properly. TCP and UDP are transport layer protocols used for data transmission, while FTP (File Transfer Protocol) is a protocol used for transferring files over a network.Rate this question:

What command do you use to clear the DNS cache on a local system?
- A.
Ipconfig /registerdns
- B.
Ipconfig /cleardns
- C.
Ipocnfig /flushdns
- D.
Ipconfig /releasedns
Correct Answer
C. Ipocnfig /flushdnsExplanation
The correct answer is "ipconfig /flushdns". This command is used to clear the DNS cache on a local system. The DNS cache stores information about previously visited websites, and clearing it can help resolve any DNS-related issues or update the cache with new information. The other options mentioned in the question, such as "ipconfig /registerdns" and "ipconfig /releasedns", are not valid commands for clearing the DNS cache.Rate this question:

What command do you use to test a system’s IPv4 protocol stack?
- A.
Ping 127.0.0.1
- B.
Ping self
- C.
Ping 255.255.255.255
- D.
Ping defaultgateway
Correct Answer
A. Ping 127.0.0.1Explanation
To test a system's IPv4 protocol stack, the command "ping 127.0.0.1" is used. This command sends a loopback message to the local host, which is identified by the IP address 127.0.0.1. By pinging this address, the system checks if the IPv4 protocol stack is functioning properly. If the system receives a response from the loopback address, it indicates that the IPv4 protocol stack is working correctly.Rate this question:

What command do you use to display active TCP or UDP connections?
- A.
Nbtstat
- B.
Netstat
- C.
Ipconfig
- D.
Nslookup
Correct Answer
B. NetstatExplanation
Use the netstat command to display active TCP (or UDP) connections, as well as a host of other statistics. Of the four columns displayed, we are concerned here with just the Proto and Local Address columns. The Proto column shows the Transport layer protocol being used for the connection; netstat, by itself, shows only TCP connections in this column. The Local Address column displays the local computer by name (server2003), followed by the outbound port number.Rate this question:

What command is used to display NetBIOS over TCP/IP statistics?
- A.
Nbtstat
- B.
Netstat
- C.
Ipconfig
- D.
Nslookup
Correct Answer
A. NbtstatExplanation
The correct answer is nbtstat. Nbtstat is a command-line tool used to display NetBIOS over TCP/IP statistics. It provides information about NetBIOS name tables, NetBIOS name cache, NetBIOS name resolution, and NetBIOS statistics. This command is commonly used in Windows operating systems to troubleshoot and gather information about NetBIOS connections and configurations.Rate this question:

What command clears the NetBIOS name cache table?
- A.
Nbtstat -r
- B.
Nbtstat -R
- C.
Nbtstat -RR
- D.
Nbtstat -s
Correct Answer
B. Nbtstat -RExplanation
The command "nbtstat -R" clears the NetBIOS name cache table. This command is used to refresh the NetBIOS name cache and remove any outdated or incorrect entries. By running this command, the system will clear the cache and rebuild it with the most up-to-date information, ensuring accurate name resolution in NetBIOS-based networks.Rate this question:

What command tests network connectivity while showing you each hop along the way?
- A.
Ping
- B.
Nslookup
- C.
Nbtstat
- D.
Tracert
Correct Answer
D. TracertExplanation
The tracert command is used to test network connectivity and display each hop along the way. It shows the path that packets take from the source to the destination, and it provides information about the time it takes for each hop. This command is commonly used to troubleshoot network issues and identify any latency or packet loss problems.Rate this question:

What command tests network connectivity while showing you each hop along the way and the degree of packet loss?
- A.
Ping
- B.
Pathping
- C.
Nbtstat
- D.
Tracert
Correct Answer
B. PathpingExplanation
Pathping is a command that combines the functionality of both ping and tracert commands. It tests network connectivity by sending multiple ICMP Echo Request messages to each hop along the way to a destination. It also provides information about the degree of packet loss at each hop, allowing you to identify network issues and troubleshoot connectivity problems more effectively.Rate this question:

What command do you use to connect to a FTP server to download a file?
- A.
Nslookup
- B.
Ssh
- C.
Telnet
- D.
Ftp
Correct Answer
D. FtpExplanation
The correct answer is "ftp". FTP stands for File Transfer Protocol, which is a standard network protocol used to transfer files from one host to another over a TCP-based network, such as the internet. By using the "ftp" command, you can establish a connection with an FTP server and download files from it.Rate this question:

What command do you use to connect to a remote computer so that you can execute commands?
- A.
Ftp
- B.
Nslookup
- C.
Telnet
- D.
Nbtstat
Correct Answer
C. TelnetExplanation
Telnet is the correct answer because it is a network protocol used to establish a remote connection to a computer over a network. It allows the user to execute commands on the remote computer as if they were directly interacting with it. This makes it a useful tool for troubleshooting, remote administration, and accessing resources on a remote system. FTP is used for file transfer, nslookup is used for DNS queries, and nbtstat is used for querying NetBIOS over TCP/IP.Rate this question:

What command can you use to connect to a mail server so that you can test SMTP?
- A.
Ftp
- B.
Nslookup
- C.
Telnet
- D.
Nbtstat
Correct Answer
C. TelnetExplanation
In addition to using the telnet command to take control of a remote computer, you can use it to test protocols. For example, if you type telnet 25, it will connect to the server using SMTP port 25.Rate this question:

What command do you use to display and modify the network configuration of a local computer?
- A.
Netsh
- B.
Netstat
- C.
Telnet
- D.
Nbtstat
Correct Answer
A. NetshExplanation
The netsh command is a built-in command-line scripting utility that enables you to display and modify the network configurations of the local computer. Netsh commands tend to be rather long and in depth, so the utility gives you the option to save configuration scripts for later use.Rate this question:
