Course Building Packet Tracer Labs for CCNA Study: Network Protocol Interactions. Training Course on Building Packet Tracer Labs for CCNA Study: Network Protocol Interactions. Cisco Packet Tracer software is a free network simulation software that allows learners to access Cisco Network Lab simulations anywhere they have access to a computer. Packet Tracer is an amazing tool for learners who can practice configuring devices and also learn how to search for proper network operation as well as troubleshoot network problems. In this training course, Building Packet Tracer Labs for CCNA Study: Network Protocol Interactions, you will learn how to build and use labs in the Cisco Packet Tracer network simulator in order to prepare for the Cisco CCNA certification exam. First, you’ll create labs to better understand the performance and configuration of Layer 2 technologies, including Etherchannel, HSRP, and Spanning Tree Protocol. Next, you’ll move on to building labs to practice creating and testing access control lists. Finally, you will practice implementing network address translation. At the end of the course, you will be able to build your own labs to practice networking technology and prepare for the concepts and objectives needed to successfully pass the Cisco CCNA exam.
