Ace the CCNA 200-301 Exam with These Must-Know Questions

The CCNA 200-301 exam is a critical step toward a successful career in networking. Whether you're a beginner or an experienced professional looking to upgrade your skills, acing this exam is essential. To help you prepare effectively, we have compiled a list of must-know questions that cover important topics tested in the CCNA 200-301. In this blog post, we will explore these questions in depth and provide detailed explanations for each answer.

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

A subnet mask is used to divide an IP network into smaller subnetworks, called subnets. It determines which part of an IP address represents the network and which part represents the host. By applying a subnet mask, network administrators can allocate IP addresses efficiently and control network traffic.

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

TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are both transport layer protocols used in computer networks. The main difference between them is that TCP provides reliable, connection-oriented communication, whereas UDP provides unreliable, connectionless communication.

Question 3: How does OSPF (Open Shortest Path First) routing protocol work?

OSPF is a link-state routing protocol used by routers to exchange routing information within an autonomous system. It calculates the shortest path to a destination using the Dijkstra algorithm and builds a database of the network topology. OSPF routers exchange hello packets to establish neighbor relationships, and they periodically update routing information to maintain an up-to-date view of the network.
