Answer: 
Explanation:
The following commands can be used to troubleshoot network connectivity problems:
ping 127.0.0.1: This command will attempt to contact the local TCP/IP protocol stack. The 127.0.0.1
address is the reserved loopback IP address, which allows applications to communicate with the local
system without using an actual IP address assigned to an interface, such as a workstations Ethernet port.
Thus, this command allows you to ping yourself?, and if successful, only verifies that TCP/IP is running
locally. It does not confirm that the system can communicate with any other host on the network.
telnet: Telnet is a network application used to establish a remote terminal connection to a host, such as
logging in remotely to a Cisco router or switch via TCP/IP. Since network applications reside on the OSI
Application Layer (Layer 7), a successful Telnet connection to a remote has confirms that there is network
connectivity through Layer 7.
arp? a: This command is used to display the local IP address to MAC address mappings on a Windows
PC.
traceroute: This command is used on a Cisco router or switch to verify, or trace, the path that IP packets will
take towards a particular destination.
tracert: This command is used on a Windows PC to verify, or trace, the path that IP packets will take
towards a particular destination.
show ip arp: This command is used to display the local IP address to MAC address mappings on a Cisco
router or switch.
