Show Suggested Answer

Suggested Answer: B, C

Switches operate atLayer 2andLayer 3of the OSI model. Here's a brief explanation for each layer:

Layer 2 (Data Link Layer):

Switches primarily operate at this layer.

They use MAC addresses to forward frames within a local network (LAN).

Switches create and maintain MAC address tables to make forwarding decisions.

Examples of switches include Ethernet switches and VLAN switches.

Layer 3 (Network Layer):

Some advanced switches (known asLayer 3 switches) can perform routing functions.

Layer 3 switches can route traffic between different subnets within the same LAN.

They use IP addresses to make routing decisions.

Layer 3 switches combine the features of switches and routers.

Switches? More like 'Layer 2 and Layer 3 Experts'. Am I right, folks?

Layer 6? Really? I think the person who wrote this question needs to go back to Networking 101.

I'm not sure about Layer 3, but I know switches definitely operate at Layer 2 for Ethernet frames.

I agree with Francoise, switches operate at Layer 2 for MAC addresses and Layer 3 for IP addresses.
