   • BA Layer 2 switch can route between VLANs, while a Layer 3 switch cannot route between VLANs.
   • CBoth Layer 2 and Layer 3 switches route between VLANs using MAC addresses.
   • DA Layer 3 switch can route between VLANs, while a Layer 2 switch cannot route between VLANs without an external router.

   A host on the 192.168.1.0/24 network needs to send a packet to a server at 10.10.10.5. The host's routing table shows no specific route to 10.10.10.0/24. What is the role of the default gateway in this scenario?

   • AIt translates the destination IP address into a public IP address before forwarding the packet.
   • BIt acts as the next hop for any destination that does not have a more specific route in the host's routing table.
   • CIt provides the MAC address of the destination server so the host can deliver the frame directly.
   • DIt responds to ARP requests on behalf of all remote hosts to reduce broadcast traffic.
