These are personal notes I took and helped me pass the CCNA exam. Feel free to use them in any way they help you.
These Notes were taken during studying Neil Anderson's course on Udemy and therefore few shapes and diagrams you will see in the notes are taken from Neil's course.
Also you can find his course for free in his YouTube channel
All files come in multiple formats. After requests I have added pdf and md formats apart from docx. If you any other request, ping me. I have made an inbound allow ACL just for that ;)
These notes follow Neil's course content. BUT there maybe be few objectives not covered in depth and other ones not covered at all. For example 'TCP/IP', 'OSI layers' and the 'IOS operating system' are not covered!. As you can see the notes start from 'IP Address classes'.
So it's adviced to take the course or any other official study material (other courses, books, Neil's free YT playlist, etc) and use these notes as an extra help to understand/memorize and go back to look an refresh your memory. You should not rely only on these notes for passing the exam. For example you should practice yourself for subnetting which is always asked in the exam.
