Networks : TRACERT vs PING vs FTP vs TELNET

Which utility would provide the output shown in the graphic exhibit?
1. FTP
2. >>TRACERT
3. TELNET
4. PING

Explanation : TRACERT is a TCP/IP utility that uses Internet Control Message Protocol (ICMP) Echo Requests to trace the route a data packet takes to its destination. The TRACERT command displays the hop count (also called the metric, the number of routers the signal must pass through to get to the destination), the time each hop takes (in milliseconds), the name of the computer or router passed through (optional), and the IP address of each router in the hop. This is the output shown in the graphic. TRACERT works with IP addresses, host names, and domain names.

The PING utility (for example, ping 208.160.120.17) is used to send test data packets to verify connectivity to another computer using ICMP. PING sends an ICMP Echo Request to a target name (like www.whitehouse.gov) or IP address. The resulting ICMP Echo Reply verifies that a TCP/IP configuration is set up properly and that the destination host is online and connected to the network.

FTP (File Transfer Protocol) is a utility program that allows the bi-directional transfer (uploading and downloading) of files between two networked hosts. A small FTP client program runs on the remote computer and accesses a larger FTP server running on a host.

The TELNET utility allows a computer to connect to a UNIX host by emulating a terminal (such as a DEC VT100) and establishing a remote command-line window.

Networks : ping vs tracert vs ftp vs telnet

Which utility is used to verify that another computer is online and connected to the network?
1. TRACERT
2. TELNET
3. >>PING
4. FTP
Explanation : The PING utility (for example, ping 208.160.120.17) is used to send test data packets to verify connectivity to another computer using ICMP. The Internet Control Message Protocol (ICMP) is part of the TCP/IP suite of protocols. It is an error-reporting protocol. PING sends an ICMP Echo Request to a target name (like computer2) or IP address. The resulting ICMP Echo Reply verifies that a TCP/IP configuration is set up properly and that the destination host is online and connected to the network.
TRACERT is also a TCP/IP utility. It uses ICMP echo requests to trace the route a data packet takes to its destination. The TRACERT command displays the hop count (also called the metric, the number of routers the signal must pass through to get to the destination), the time each hop takes (in milliseconds), the name of the computer or router passed through (optional), and the IP address of each router in the hop. TRACERT works with IP addresses, host names, and domain names. Like PING, TRACERT can verify a system is online, but that is not its primary purpose.

FTP (File Transfer Protocol) is a utility program that allows the bi-directional transfer (uploading and downloading) of files between two networked hosts. A small FTP client program runs on the remote computer and accesses a larger FTP server running on a host. FTP is not used to verify that another system is online.

The TELNET utility allows a computer to connect to a UNIX host by emulating a terminal (such as a DEC VT100) and establishing a remote command-line window. TELNET is not used to verify that another system is online.

Networks: Retrieving the MAC address

What command would you use to retrieve a computer's MAC address?
1. >>ping
2. tracert
3. ipconfig
4. netstat

Explanation : You should use the ipconfig command and run ipconfig /all to retrieve a computer's Media Access Control (MAC) address. The MAC address is the address that is hard-coded on the computer's network interface card (NIC).

You should not use the ping command to retrieve a computer's MAC address. The ping command is used to trace communication between two computers.

You should not use the tracert command to retrieve a computer's MAC address. The tracert command is used to test communication with another computer and return detailed routing information.

You should not use the netstat command to retrieve a computer's MAC address. The netstat command is used to view networking status information. For example, the netstat command can be used to identify which ports are open and are monitored ("listened to") by the computer. Ports are used to direct network traffic to the appropriate service or application. The most commonly used default ports are defined as well-known ports. Ports often found open on a Windows computer include port 80, which is the default for Hypertext Transfer Protocol (HTTP) traffic for Web-related traffic, and port 53, which is used for Domain Name Service (DNS) traffic.

Networks: Communication routes

A computer is unable to communicate with a different computer located on a remote network.
How can you determine at what point the communication is failing?
1. >>Run tracert
2. Run ipconfig.
3. Run netstat.
4. Run nslookup.

Explanation : You should run tracert, followed by the destination computer name or address. The tracert command tests each hop between the source and destination computers. The tracert command can be used to determine the route taken to the destination computer and can be used to determine the point at which communication fails.

You should not run ipconfig to determine at what point the communication is failing. The ipconfig command is used to view IP configuration information and to release or renew IP address leases, that is, an address received from a Dynamic Host Configuration Protocol (DHCP) server.

You should not run netstat to determine at what point the communication is failing. The netstat command lets you view a wide range of networking statistics. For example, the netstat command can be used to identify which ports are open and are monitored ("listened to") by the computer. Ports are used to direct network traffic to the appropriate service or application. The most commonly used default ports are defined as well-known ports. Ports often found open on a Windows computer include port 80, which is the default for Hypertext Transfer Protocol (HTTP) traffic for Web-related traffic, and port 53, which is used for Domain Name Service (DNS) traffic.

You should not run nslook to determine at what point the communication is failing. The nslookup command is used with the Domain Name Service (DNS) and can be used to locate DNS servers and test DNS service operations.
