World of Computer Networking Your CCNA start - Default Routes Usage

The video tutorial explains the setup and configuration of routing tables for three routers (R1, R2, and R3) in a local area network. It details how R2 connects to the internet and manages static and default routes to ensure network accessibility. The tutorial also covers the routing tables of R1 and R3, emphasizing the use of default routes for simplicity. Finally, it discusses the process of making routing decisions and the interdependence of routes within routing tables.

What type of IP addresses are typically used in a local area network?

• Private IP addresses

• Public IP addresses

• Static IP addresses

• Dynamic IP addresses

Which router is used as the outgoing point to the Internet in this network setup?

• R1

• R2

• R3

• ISP Router

What is the purpose of a default route in a routing table?

• To route packets to a specific local network

• To provide a backup route in case of failure

• To route packets to any destination not in the routing table

• To connect directly to the ISP

How many directly connected routes does R2 have?

• One

• Two

• Three

• Four

What type of routes are added to R2 to reach networks behind R1 and R3?

• Temporary routes

• Static routes

• Dynamic routes

• Default routes

How many directly connected routes does R1 have?

• Four

• Three

• Two

• One

What is the next hop IP address for the default route on R3?

• 10.5.1.1

• 10.5.1.2

• 10.17.2.1

• 10.17.2.2

Why can't a static route with an incorrect next hop IP be added to R3's routing table?

• The IP address is reserved

• The IP address is not in the same subnet

• The IP address is already in use

• The IP address is not reachable

What is the main reason for using static routes in this network setup?

• To reduce network traffic

• To improve security

• To allow dynamic changes

• To simplify the routing process

What is the role of the ISP router in this network configuration?

• To manage local network traffic

• To monitor network security

• To provide Internet access

• To assign IP addresses
