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?
A.
A remote physical layer problem exists.
B.
The host NIC is not functioning.
C.
TCP/IP has not been correctly installed on the host.
D.
A local physical layer problem exists.
The host clearly can’t get out of its network because it can’t communicate with the gateway(router), but what makes that a physical layer problem?

The first two successful pings indicate that the NIC and the TCP/IP stack are functioning properly. That eliminates B and C. The first unsuccessful ping indicates that the host cannot reach its gateway. There is no way to determine if there is a physical layer problem downstream of the router since you cannot even reach the router. That would only leave a physical layer issue between the host and the router. Only D works in this case.

Ping is a computer network administration software utility used to test the reachability of a host on an Internet Protocol (IP) network and to measure the round-trip time for messages sent from the originating host to a destination computer and back.

Ping Command is the way to test the Network Adapter (NIC, also known as a network interface card, network adapter). The NIC is both a physical layer and data link layer device.
