CCNA 2 Chapter 7 Questions and Answers

Chapter 7 of the CCNA 2 course focuses on dynamic routing protocols. In this blog post, we will explore key concepts and provide a set of practice questions with detailed answers to help you solidify your understanding of dynamic routing protocols.

1. What is a dynamic routing protocol?

A dynamic routing protocol is a protocol that allows routers to exchange routing information automatically. It enables routers to dynamically learn and adapt to changes in the network topology, ensuring efficient and reliable routing.

2. What are the advantages of dynamic routing?

Dynamic routing offers several advantages:

  • Automatic network adaptation to changes
  • Load balancing across multiple paths
  • Redundancy and fault tolerance
  • Reduced administrative overhead

3. Name some popular dynamic routing protocols.

There are various dynamic routing protocols used in different environments:

  1. Routing Information Protocol (RIP)
  2. Open Shortest Path First (OSPF)
  3. Enhanced Interior Gateway Routing Protocol (EIGRP)
  4. Border Gateway Protocol (BGP)

4. How does RIP work?

RIP is a distance vector routing protocol that uses hop count as the metric. Routers exchange routing tables containing their known routes, and each router selects the path with the fewest hops to reach a destination. RIP updates are sent periodically to inform neighboring routers about network changes.

5. Explain the concept of link-state routing.

Link-state routing protocols, such as OSPF, operate by building a detailed map of the network. Each router floods link-state advertisements (LSAs) containing information about the router’s directly connected links. By exchanging LSAs, routers construct a complete topology map, enabling them to calculate the shortest path to each network.
