routing protocols : Static Routes and Dynamic Routes

The video tutorial explains how a PC's IP address and default gateway work, using a Cisco router as an example. It covers the routing table, static routes, and default routes, demonstrating how traffic is forwarded through routers. The tutorial also discusses the traceroute command and DNS resolution, showing how traffic reaches external sites like Google. Finally, it explains router configuration and gateway settings, emphasizing the hop-by-hop paradigm in networking.

What is the primary role of a default gateway in a network?

• To assign IP addresses to devices

• To manage local network traffic

• To route traffic to external networks

• To block unauthorized access

Which command is used to view the routing table on a Cisco router?

• show ip interface

• show ip route

• show ip protocols

• show ip arp

What does a static route in a routing table indicate?

• A manually configured route

• A route learned from a neighbor

• A default route for all traffic

• A temporary route for testing

What is the purpose of the traceroute command?

• To configure static routes

• To trace the path packets take to a destination

• To measure network speed

• To resolve DNS names

What happens when a static route is removed from a router's configuration?

• All network traffic is blocked

• DNS resolution fails for certain addresses

• Traffic is rerouted through the default gateway

• The router stops functioning

What is the role of a home router's default gateway?

• To manage local DNS settings

• To assign IP addresses to devices

• To connect the home network to the Internet

• To block incoming traffic

How do routers make decisions on where to forward traffic?

• Randomly selecting a path

• By consulting a central server

• Using a hop-by-hop paradigm

• Based on the fastest route
