3. Refer to the exhibit. A technician is troubleshooting a host connectivity problem. The host is unable to ping a server connected to Switch_A. Based on the results of the testing, what could be the problem?

4. An administrator issues the command ping 127.0.0.1 from the command line prompt on a PC. If a reply is received, what does this confirm?
A: The PC has connectivity with a local host.
B: The PC has connectivity with a Layer 3 device.
C: The PC has a default gateway correctly configured.
D: The PC has connectivity up to Layer 5 of the OSI model.
E: The PC has the TCP/IP protocol stack correctly installed.
Correct Answers: E
Explanation:
Every Windows based PC uses the 127.0.0.1 as the local loopback IP address. Every PC will respond to this local IP address if the TCP/IP stack is correctly installed and running on the machine. If you cannot ping the loopback address of 127.0.0.1, then something is wrong with the TCP/IP protocol stack.
