The exam duration is 120 minutes, and you need to achieve a passing score to earn the certification.

Sample CCNA Exam Questions and Answers

  • Question 1: What is the main purpose of Spanning Tree Protocol (STP)?

    Answer: STP is used to prevent loops in switched networks by dynamically identifying and blocking redundant paths while keeping the active paths available for forwarding traffic. It ensures network redundancy without causing broadcast storms or MAC address table instability.

  • Question 2: How does IPv6 differ from IPv4?

    Answer: IPv6 provides a larger address space than IPv4, which was a major limitation of the older protocol. Additionally, IPv6 incorporates built-in security features with IPsec and simplifies network configuration by using stateless address autoconfiguration.

  • Question 3: What is the purpose of a VLAN (Virtual Local Area Network)?

    Answer: VLANs are used to logically segment a single physical network into multiple virtual networks. This segmentation allows for improved security, simplified management, and better resource allocation. VLANs can span multiple switches and can be used to isolate traffic and optimize network performance.


In conclusion, the CCNA certification is a valuable credential for networking professionals. The exam tests your understanding of fundamental networking concepts and ensures you have the necessary skills to deploy and manage network solutions. By reviewing the sample questions and answers provided in this blog post, you’ll be well-prepared for success in the CCNA exam. Good luck in your certification journey!
