Which route is used when no other specific route matches and typically points to the ISP gateway?

• A. Default Route
• B. Routing
• C. ARP
• D. Switch Chip

Answer: (A)

When a router doesn’t find a more specific path for a destination, it uses a catch-all path called the default route. This route is typically configured as 0.0.0.0/0 (for IPv4) and points to the next hop, usually the ISP gateway, so all traffic destined for networks not in the local routing table is forwarded toward the Internet. In practice, DHCP or manual setup often populates this default route to your ISP’s router. ARP resolves local addresses, switching handles layer-2 forwarding, and routing is the overall process of choosing paths; none of those alone defines the catch-all path. So the default route is the route used when nothing else matches.
