These notes represent my personal interpretation and understanding of CCNA-related topics. I created this summary for study purposes, based on a combination of various publicly available resources. These include the official Cisco documentation, educational videos from the Jeremy’s IT Lab YouTube channel, and content from other creators and sources.
This is not a copy of any specific course or video, and it is not affiliated with or endorsed by Cisco or Jeremy’s IT Lab. While I strive for accuracy, there may be mistakes or simplifications, as this summary reflects my own learning process.
If you are preparing for the CCNA exam, please verify the information with official or primary sources.
