CCNA Routing and Switching Exam Questions and Answers 2016

Welcome to our blog post covering the CCNA Routing and Switching exam questions and answers from 2016. In this article, we will provide you with a comprehensive review of the questions that were asked in the exam, along with their answers. Whether you’re preparing for the exam or simply curious about the topics covered, this guide will be highly beneficial.

Exam Overview

The CCNA Routing and Switching certification is one of the most sought-after credentials for network engineers. It validates your knowledge and skills in networking fundamentals, LAN switching technologies, IPv4 and IPv6 routing technologies, WAN technologies, infrastructure services, and security.

The exam held in 2016 consisted of several sections focusing on these key areas. Let’s delve into the questions that were asked and their respective answers:

Question 1:

What is the function of a default gateway in a network? Explain with an example.

Answer:

A default gateway is a device (usually a router) that acts as an access point for other networks. It provides a path for network devices to follow when they need to communicate with devices on a different network. For example, if a computer on a local network wants to access a website on the internet, it sends the request to the default gateway, which then forwards it to the appropriate destination. Without a default gateway, devices on a network would be unable to communicate with devices on other networks.

Question 2:

What is the difference between a switch and a router? How do they contribute to network communication?

Answer:

A switch is a layer 2 device that operates at the data link layer of the OSI model. It connects devices within a local network and uses MAC addresses to forward data between devices. Switches create multiple collision domains, improving overall network performance.

A router, on the other hand, is a layer 3 device that operates at the network layer of the OSI model. Its primary function is to connect multiple networks together and route data packets between them based on IP addresses. Routers enable intercommunication between different networks, ensuring data reaches its intended destination.

Question 3:

What is the purpose of subnetting? How does it help in optimizing network resources?

Answer:

Subnetting is the process of dividing a network into smaller, more manageable subnetworks. It allows for efficient utilization of IP addresses and improves network performance. By dividing a network into subnets, network administrators can control network traffic, apply security policies, and create logical groupings of devices based on their functionality or location. Subnetting facilitates efficient resource allocation and enhances overall network scalability.

Question 4:

Explain the difference between static routing and dynamic routing. Which one would you choose in a scenario where a network has multiple redundant paths?

Answer:

Static routing is a manual process in which network administrators define the path of network traffic by configuring routing tables directly on routers. It requires manual intervention whenever network changes occur, making it less suitable for large or complex networks. Static routing is generally preferred in small networks with a simple topology and fewer devices.

Dynamic routing, on the other hand, uses routing protocols to automatically update routing tables based on network changes. It is recommended for large networks or scenarios where multiple redundant paths exist since it can dynamically adapt to changes and ensure efficient traffic distribution.

Question 5:

What are VLANs and how do they enhance network security and performance?

Answer:

VLANs (Virtual Local Area Networks) are logical groupings of devices within a network, even if they are physically dispersed. VLANs enhance security by isolating specific groups of devices from others, restricting unauthorized access between devices within different VLANs. They also improve performance by reducing broadcast traffic and allowing network administrators to prioritize certain types of traffic.

Conclusion

These were just a few examples of the questions asked in the CCNA Routing and Switching exam from 2016. A deep understanding of networking concepts and technologies is crucial to passing the exam successfully. We hope this article has provided you with valuable insights into the type of questions you might encounter in the exam. Good luck with your preparation!
