What table does a switch use to map destination addresses to outgoing ports when forwarding frames?
MAC address table
VLAN database
Routing table
ARP table
A switch uses its MAC address table to map destination MAC addresses to specific ports. When a frame arrives, the switch looks up the destination address in the MAC address table to decide which port to forward the frame out of. ARP tables map IP addresses to MAC addresses and are used by devices to resolve Layer 3 addresses to Layer 2 addresses, not for frame forwarding decisions within a switch. Routing tables are used by routers to forward packets based on IP addresses, functioning at Layer 3. VLAN databases store VLAN configurations and are not used in determining frame forwarding decisions.
