Training and Development

Mercury Solutions Limited is the authorized training partner of Cisco providing quality training and trained thousand of professionals in last 15 years on various technologies like Cisco, VMware, EC-council, Microsoft, Oracle, Red Hat, Apple, CISA, Citrix, CISSP, CompTIA, etc. No one can give you 100% passing guarantee of CCNA it depends on you. If somehow you managed to pass with the help of the institution you won't acquire deep knowledge of the course. In my opinion you should focus on quality training where certified and experienced trainers are providing quality training in Cisco authorized training institute. It will definitely increases your knowledge and boost your career. Make a time schedule and stick to it. Study seriously, with passion if you really want to learn. Do practicals thoroughly. Book the exam and give it confidently.

Generally, as far as the basic qualification is considered, a Bachelor degree is good to have or of course more if you do like. As far as percentage cut off is concerned, it could vary from company to company. The course background could be an MBA, BE, B.com/BBM/BA etc. It is not necessarily a must to have certain background only. However, the education background helps to assure the recruiters that you have a thorough skill set and specialisation in a certain area. If that area of interest is what their company can relate to, then nothing like it. Good experience in actual training and development will prove much more beneficial. Some certifications links that I can think of are:
