CCNA 200-120 Subnetting Questions – A Comprehensive Guide

Subnetting is an essential concept in networking, and it plays a crucial role in the Cisco Certified Network Associate (CCNA) 200-120 certification exam. As a CCNA candidate, mastering subnetting is imperative for both theoretical knowledge and real-world implementation. This blog post will provide you with a detailed overview of subnetting, explain its significance, and present a comprehensive set of subnetting questions to help you prepare for the CCNA 200-120 exam.

What is Subnetting?

Subnetting refers to the process of dividing a network into smaller subnetworks, which are known as subnets. It allows efficient utilization of IP addresses, enables better network management, and enhances scalability and security. Understanding the subnetting process is vital in networking, as it requires the ability to determine network addresses, broadcast addresses, valid hosts, and identify subnet masks.

The Significance of Subnetting in CCNA 200-120 Exam

Subnetting is a fundamental skill that a CCNA candidate must possess. It demonstrates expertise in IP addressing and network design. The CCNA 200-120 exam evaluates your understanding of subnetting and assesses your ability to perform subnetting calculations, subnet mask configuration, and subnet planning. A strong grasp of subnetting concepts will significantly contribute to your success in attaining the CCNA certification.

CCNA 200-120 Subnetting Questions

Now, let’s dive into a set of carefully selected subnetting questions that will test your knowledge and enhance your problem-solving skills:

1. What is the maximum number of hosts allowed in a subnet with a subnet mask of

2. Given a network address of, what is the broadcast address for this subnet?

3. Which subnet mask provides 30 usable host addresses for a subnet?

4. If a network has a subnet mask of and requires at least 60 hosts per subnet, what is the minimum bit representation needed for the host portion of the IP address in binary?

5. What is the subnet address for a host with IP address


In this blog post, we explored the importance of subnetting in the CCNA 200-120 exam and provided a comprehensive set of subnetting questions to enhance your understanding. Subnetting is a foundational concept in networking, and mastering it is essential for any aspiring network engineer.
