Manoj Verma
Manoj Verma - CCIE # 43923 is a highly experienced senior technical instructor and Network/ security consultant. He has been in the networking industry for more than 19 years, with a focus on networking and security for the past 15 years. He has assisted thousands of engineers in obtaining their various certifications starting from CCNA to CCIE, CCSA, CCSE, PCNSE, F5, etc. and learning the latest and cutting-edge technologies.  He started his career as a system administrator and then switched to the networking and security domain. During the job, he realized that he is gifted with a passion for teaching and sharing his knowledge, as he used to teach his colleagues and friends. In his classroom training, he always starts with explaining the theory on a certain topic and then gives away a short note of key points and finally end with lab implementation. Now a day, driving down to the training institute to attend classroom training sessions is not feasible for everyone owing to the workflow, odd working hours and rotational shifts, especially for working professionals and those who are living in different cities and countries. He started getting multiple requests from lots of students to launch an online training module in the same way as he teaches in his classrooms. Keeping all this in mind, he designed this self-paced training module which replicates classroom training. He has brought his years of classroom teaching experience, and years of real-world enterprise and service provider experience in designing training modules. For a better understanding of technologies and in-depth knowledge, reading books or short notes is necessary and to witness the theoretical information in live, practical knowledge is required so he has included both which is very unique in the IT training sector.
