Cisco Packet Tracer សំរាប់ Cisco ថ្នាក់ដំបូង

Having a good environment is very importent for practicing CCNA, some of you might have a great lab full of cisco routers, switches and firewalls, which is the best, but Cisco introduced Packet Tracer a Router Simulator for those who have only one computer at their bedroom's and thinking how to practice without any router or switch?. Packet Tracer is a simulator that provides a learning environment for networking novices to design, configure, and troubleshoot computer networks at a CCNA-level of complexity.

Packet Tracer Version 5.3.3

Packet Tracer version 5.3.3 is a maintenance release that fixes functional and technical issues in the previous versions. It replaces Packet Tracer version 5.3.2. Packet Tracer 5.3.3 supports activities authored in Packet Tracer 4.x, 5.0.x, 5.1.x, 5.2.x, and 5.3.x. Please note that the last two courses of the CCNA Discovery and CCNA Exploration curricula require Packer Tracer version 4.11 at a minimum, CCNA Security requires version 5.2 at a minimum, and the Packet Tracer Skilled Based Assessments require version 5.3.2 at a minimum. the curricula are fully compatible with Packet Tracer 5.3.3.

You can download both the Packet Tracer application and tutorial filed in one download package. However, due to the large file size it is faster to download the application by itself, if that is all you need. After Downloading and installing one of the following Type of Packet Tracer 5.3.3 which matches your OS, you will be able to start CCNA Tutorials. according to me you should start Practicing CCNA from Different Modes and Prompts of a Cisco Router IOS.
