What is the primary purpose of a default gateway in a network?
Answer: To forward traffic destined for networks outside the local subnet
A default gateway forwards packets destined for networks not on the local subnet.
Which command displays the routing table on a Cisco router?
Answer: show ip route
The 'show ip route' command displays the complete IP routing table including connected, static, and dynamic routes.
What does a Layer 2 switch use to make forwarding decisions?
Answer: MAC addresses
Layer 2 switches use MAC addresses stored in a CAM table to forward frames to the correct port.
What is the administrative distance of a directly connected route?
Answer: 0
Directly connected routes have an administrative distance of 0, the most trustworthy value.
Which switching method examines only the destination MAC address before forwarding a frame?
Answer: Cut-through
Cut-through switching reads only the first 6 bytes (destination MAC) before forwarding, providing lowest latency but no error checking.
What is the purpose of the ARP protocol in networking?
Answer: To resolve IP addresses to MAC addresses
ARP resolves a known IP address to an unknown MAC address on the local network segment for Layer 2 frame delivery.
