Free CCNA 200-125 Exam Questions: Test Your Networking Skills

The Cisco Certified Network Associate (CCNA) certification is a valuable credential for professionals in the field of networking. If you’re preparing for the CCNA 200-125 exam, it’s essential to test your knowledge and skills before the actual examination date. In this blog post, we provide a collection of free CCNA 200-125 exam questions to help you assess your preparedness and strengthen your understanding of networking concepts.

1. Question:

What is the purpose of the ARP (Address Resolution Protocol)?


The ARP protocol is used to resolve or map an IP address to a MAC address in a local area network (LAN) environment. It allows devices to communicate with each other using hardware addresses (MAC) instead of IP addresses.

2. Question:

What are the differences between TCP and UDP?


TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are both transport layer protocols, but they differ in several ways:

  • TCP is connection-oriented, while UDP is connectionless.
  • TCP guarantees reliable and ordered delivery of data, while UDP does not provide reliability or ordering.
  • TCP performs error checking and retransmits lost packets, while UDP does not.
  • TCP has higher overhead due to additional features, while UDP is lightweight.

3. Question:

What is the purpose of the subnet mask?


A subnet mask is used to divide an IP network into subnetworks or subnets. It helps determine the network and host portions of an IP address. By applying the subnet mask to an IP address, the network device can identify which part represents the network and which part represents the host.

4. Question:

What is the difference between a router and a switch?


A router and a switch are both network devices, but they have different functionalities:

  • A router operates at the network layer (Layer 3) of the OSI model and can connect multiple networks together. It makes decisions about the best path for forwarding packets from one network to another.
  • A switch operates at the data link layer (Layer 2) of the OSI model and is used to connect devices within the same network. It forwards data frames to the intended recipient based on MAC addresses.

These are just a few examples of the free CCNA 200-125 exam questions you can find to gauge your knowledge. It’s important to thoroughly understand networking concepts and practice with various question formats to increase your chances of success in the exam.


Preparing for the CCNA 200-125 exam requires a solid understanding of networking principles. By practicing with free exam questions, you can assess your knowledge and identify areas for improvement. Remember to study consistently and consult additional study materials to ensure you’re fully prepared for the exam. Good luck!
