CCNA Final Exam Questions and Answers – 2018

Welcome to our blog, where we will be discussing the CCNA final exam questions and answers from the year 2018. This exam is a critical milestone for anyone pursuing a career in networking. It tests your knowledge and skills in various networking concepts, protocols, and technologies.

Question 1:

What is the purpose of a subnet mask?

Answer: A subnet mask is used to divide an IP address into network and host portions. It helps determine which part of the IP address represents the network and which part represents the host.

Question 2:

Explain the difference between TCP and UDP protocols.

Answer: TCP (Transmission Control Protocol) is a reliable, connection-oriented protocol that guarantees the delivery of data packets to the destination. It provides error-checking, flow control, and congestion control mechanisms. UDP (User Datagram Protocol) is an unreliable, connectionless protocol that does not guarantee packet delivery. It is often used for real-time applications where speed is more important than reliability.

Question 10:

What is the purpose of VLANs (Virtual Local Area Networks)?

Answer: VLANs are used to logically segment a network into multiple broadcast domains. They help improve network performance, security, and manageability by grouping devices based on their functions or departments, regardless of the physical location.

Question 11:

Explain the process of subnetting a network.

Answer: Subnetting involves dividing a network into smaller subnetworks. The process includes determining the required number of subnets, assigning subnet masks, and distributing IP addresses accordingly. Subnetting helps optimize network resources and improves scalability.

Question 20:

What is the purpose of STP (Spanning Tree Protocol) in Ethernet networks?

Answer: STP is used to prevent loops in Ethernet networks. It dynamically selects the best path for forwarding data while blocking redundant paths. This ensures a loop-free topology and avoids broadcast storms that can cause network congestion.

We hope you found this collection of CCNA final exam questions and answers from 2018 helpful. Remember, preparing for your certification exam requires a solid understanding of networking concepts and hands-on experience. Good luck with your studies!
