Which device connects multiple network segments and operates at the Data Link Layer of the OSI model?Group of answer choicesRouterSwitchHubBridge

To determine which device connects multiple network segments and operates at the Data Link Layer of the OSI model, let's analyze the given options:

1. Router: Operates at the Network Layer (Layer 3) and is used for routing traffic between different networks.

2. Switch: Primarily functions at the Data Link Layer (Layer 2) and is used to connect multiple devices within the same network segment, making decisions based on MAC addresses.

3. Hub: Operates at the Physical Layer (Layer 1) and simply forwards data to all devices in a network segment without filtering.

4. Bridge: Also operates at the Data Link Layer (Layer 2) and is used to connect two or more network segments, filtering traffic and reducing collisions.

Final Answer

Switch and Bridge are both correct. However, since the question specifically asks for a device that connects multiple network segments and operates at the Data Link Layer, the best answer would be Bridge.
