which of the following is a device that works at the second physical layer of the osi model and allows two lans to form a larger network?
○ a switch
○ a bridge
○ a hub
○ an extranet

Explanation:

The OSI model's second layer is the Data Link Layer. A bridge operates at this layer and connects two local area networks (LANs) to form a larger network. A switch also works at the Data Link Layer but typically connects devices within a single LAN. A hub operates at the Physical Layer (first layer). An extranet is a network extension, not a device.

Answer:

B. a bridge
