Key Exam Questions and Answers

Let’s dive into a selection of CCNA exam questions from 2018 and their corresponding answers:

  1. Question 1: What is the purpose of a subnet mask?

    Answer: A subnet mask is used to determine the network and host portions of an IP address. It helps differentiate between the network and host addresses, allowing routers to route packets efficiently.

  2. Question 2: What is the difference between TCP and UDP?

    Answer: TCP (Transmission Control Protocol) is a reliable and connection-oriented protocol that ensures data delivery and ordered sequencing. UDP (User Datagram Protocol) is a faster but connectionless protocol that does not guarantee reliable data delivery or ordered sequencing.

  3. Question 3: How does STP (Spanning Tree Protocol) prevent network loops?

    Answer: STP prevents network loops by electing a root bridge and selecting the best path to reach the root bridge. It blocks redundant links to avoid loop formation and ensures a loop-free topology.
