A technician installed a network adapter in a computer and wants to test network connectivity. The ping command can receive responses from workstations on the same subnet but not from remote workstations. What could be causing the problem?

• The operating system is not compatible with the remote sites.
• The TCP/IP protocol stack is not loaded.
• The default gateway is incorrect.
• The NIC driver is out of date.

Explanation: The default gateway is the interface IP address of the router that is connected to the local network. The function of the router is to enable communication among different networks. If the default gateway is not set or is incorrect, packets that are destined to other networks will not be able to reach the router, and hence there will be no communication to hosts that are located in other networks.
