A. B. C. D.C
In this scenario, where Host A is communicating with Host B through a Layer 2 switch, the highest layer that the switch will inspect the traffic is the Data Link layer.
The Data Link layer is responsible for the transfer of data between adjacent network nodes, such as from Host A to the Layer 2 switch, and from the Layer 2 switch to Host B. The Layer 2 switch inspects and uses the Media Access Control (MAC) addresses in the Ethernet frames to forward the frames to their correct destination.
The Transport layer is responsible for end-to-end communication between hosts, providing reliable data transfer through mechanisms such as flow control, error detection, and error recovery. However, the Layer 2 switch does not operate at this layer and does not inspect or manipulate the Transport layer protocols.
The Session layer is responsible for establishing, maintaining, and terminating sessions between applications. However, the Layer 2 switch does not operate at this layer and does not inspect or manipulate the Session layer protocols.
The Network layer is responsible for logical addressing and routing of data between hosts on different networks. However, in a Layer 2 switch scenario, the switch does not perform routing functions and does not inspect or manipulate the Network layer protocols.
Therefore, the correct answer is C. Data Link, as the Layer 2 switch only inspects the MAC addresses in the Ethernet frames to forward them to their correct destination.
