CCNA 2 Chapter 3 Questions and Answers

Introduction

Welcome to our blog post on CCNA 2 Chapter 3! In this article, we will cover a set of questions and answers that will help you assess your understanding of the topics discussed in this chapter. CCNA 2, also known as the Routing and Switching Essentials, is a foundational course in Cisco’s networking certification program. Chapter 3 focuses on static routing, default routes, and dynamic routing protocols. Let’s dive into the questions!

Q&A: Static Routing

Q1: What is static routing?

A1: Static routing is a method of routing where network administrators manually configure the routing table entry on a router. It does not rely on dynamic routing protocols, and each entry must be added or removed manually.

Q2: What are the advantages and disadvantages of static routing?

A2: The advantages of static routing include lower overhead on router resources, improved security due to limited route updates, and predictable path selection. However, the disadvantages are a lack of flexibility in adapting to network changes and increased configuration complexity with larger networks.

Q&A: Default Routes

Q3: What is a default route?

A3: A default route is a special routing table entry that enables a router to forward packets for destinations not explicitly listed in its routing table. It is typically used as a “last resort” when no other routes match the destination IP address.

Q4: How do you configure a default route?

A4: To configure a default route, use the following command: ip route 0.0.0.0 0.0.0.0 next-hop-ip. Replace next-hop-ip with the IP address of the next hop router towards the destination.

Q&A: Dynamic Routing Protocols

Q5: What are dynamic routing protocols?

A5: Dynamic routing protocols are network protocols that enable routers to exchange routing information with each other automatically. These protocols allow routers to dynamically learn and update routing table entries based on network changes.

Q6: Name two dynamic routing protocols commonly used in enterprise networks.

A6: Two commonly used dynamic routing protocols in enterprise networks are Routing Information Protocol (RIP) and Enhanced Interior Gateway Routing Protocol (EIGRP).

Conclusion

Congratulations on completing this Q&A session on CCNA 2 Chapter 3! We hope this article helped you reinforce your understanding of the different concepts discussed, including static routing, default routes, and dynamic routing protocols. Remember to keep practicing and exploring additional resources to solidify your knowledge. Happy networking!
