I had the privilege of being trained by Mr. Abid Khan, an outstanding CCIE instructor who excels in the industry. His extensive knowledge of CCIE Route/Switch concepts and ability to simplify complex ideas make him exceptional. Abid Sir's lectures on STP, BGP, and multicast demonstrated his profound knowledge and effective teaching style. I appreciate both his training and mentoring, including valuable insights on scheduling and pacing my learning to meet my certification timelines. I wholeheartedly recommend Mr. Abid Khan without reservation. His well-deserved credibility and industry reputation speak volumes.
