A user is unable to open up websites on the Internet from a browser. The administrator determines that the workstation can ping its local gateway, but not the remote web server. At which of the…

The Data Link layer (Layer 2) handles local MAC-based communication, and since the workstation can successfully ping its gateway on the local segment, Layer 2 is confirmed functional.

The Network layer (Layer 3) is responsible for logical addressing and routing between networks. Because the workstation can successfully ping its local default gateway, Layers 1 and 2 are functioning correctly. The failure to reach a remote host beyond the gateway indicates a routing issue - such as a missing or incorrect route - which is a Layer 3 problem.

The Session layer (Layer 5) manages connection establishment between applications; the problem here is a network reachability issue, not a session-level failure.

The Physical layer (Layer 1) involves cables and signals; a physical failure would prevent any connectivity, including the successful local gateway ping.
