CCNA Certification Practice Questions

Are you preparing for the CCNA certification exam and looking for practice questions to test your knowledge? Look no further! In this blog post, we will provide you with a variety of CCNA certification practice questions to help you ace the exam.

Question 1: OSI Model

Which layer of the OSI model is responsible for ensuring reliable end-to-end communication between hosts?

  1. Physical Layer
  2. Data Link Layer
  3. Transport Layer
  4. Network Layer

Question 2: Routing Protocols

Which routing protocol is a classless routing protocol that supports Variable Length Subnet Masks (VLSM)?

  1. RIP
  2. OSPF
  3. EIGRP
  4. BGP

Question 3: VLANs

What is the purpose of using VLANs (Virtual Local Area Networks) in a network infrastructure?

  1. To separate broadcast domains
  2. To extend the range of a physical LAN
  3. To enable dynamic IP addressing
  4. To encrypt network traffic

Make sure to think through each question carefully, and once you’ve chosen your answer, scroll down to see the correct answer and an explanation.

Answer 1: OSI Model

Correct Answer: C – Transport Layer

Explanation: The Transport Layer is responsible for ensuring reliable end-to-end communication between hosts. It provides error recovery and flow control mechanisms.

Answer 2: Routing Protocols

Correct Answer: B – OSPF

Explanation: OSPF (Open Shortest Path First) is a classless routing protocol that supports Variable Length Subnet Masks (VLSM). It allows for efficient IP address allocation and provides better scalability compared to RIP.

Answer 3: VLANs

Correct Answer: A – To separate broadcast domains

Explanation: VLANs are used to logically separate broadcast domains within a network. By default, devices within the same VLAN can communicate with each other, but not with devices in other VLANs without routing.

Continue practicing with more questions to strengthen your CCNA knowledge and improve your chances of passing the certification exam. Good luck!
