CCNA 2 Chapter 6: Routing and Routing Protocols – Questions and Answers

Q1: What is routing and why is it important in networking?

Routing is the process of forwarding packets between different networks. It is a crucial aspect of networking as it allows data to travel efficiently across multiple networks and reach its intended destination. Without routing, communication between different networks would not be possible.

Q2: What are the two main types of routing protocols?

The two main types of routing protocols are:

  • Interior Gateway Protocols (IGPs): These protocols are used for routing within an autonomous system, such as a single organization’s network.
  • Exterior Gateway Protocols (EGPs): These protocols are used for routing between multiple autonomous systems, such as different organizations’ networks.

Q3: What is the purpose of a default route?

A default route, also known as the gateway of last resort, is used when a router is unable to find a specific route for a destination network in its routing table. It serves as a fallback route and directs traffic to a predefined gateway, such as the internet service provider’s router. This allows communication with networks outside the local network.

Q4: What is the difference between static and dynamic routing?

Static routing involves manually configuring routes on each router, specifying the next-hop IP address for each destination network. It is suitable for small networks with a static network infrastructure.

Dynamic routing, on the other hand, uses routing protocols to dynamically exchange routing information between routers. The routers automatically learn about the available routes and update their routing tables accordingly. Dynamic routing is preferred for large networks or networks that frequently change their topology.

Q5: What is the purpose of a routing table?

A routing table is a database maintained by a router that contains information about known networks, the next-hop IP addresses, and the preferred routes to reach those networks. It is used by the router to make forwarding decisions and determine the best path for forwarding packets towards their destinations.
