You are working at the help desk and you get a message that a user cannot access the Internet. You open a command prompt, ping the workstation's IP address, and get a response. You ask the user to try the Internet again. He does so with the same result-no connection. Which type of device is most likely to be the problem?
A) Physical layer device
B) Data Link layer device
C) Network layer device
D) Presentation layer device

Since the workstation's IP address responded to the ping request, it indicates that the physical layer and data link layer devices (such as the network interface card and switch) are functioning properly. The issue is likely at the network layer, which could include the router or firewall preventing the user from accessing the Internet. The presentation layer is responsible for formatting data and is not involved in network connectivity issues.
