If you are doing self-study, you must think of enrolling in a good institute that can train you in the CCNA syllabus. A good training institute such as Softlogic Systems in Chennai can offer the best training in CCNA via both theory and lab sessions. Softlogic also has an in-house Pearson Vue testing centre where you can take the CCNA exam. So, enrol yourself in the CCNA networking program at Softlogic Chennai.
CCNA (Cisco Certified Networking Administrator) is offered by Cisco Corporation which has designed the course by including all the major networking concepts and Cisco network products.
The CCNA certification offered by Cisco may be little difficult to clear. But, once you clear the exam you will be a hot property in the networking job market. Failure is the stepping stone for success. So, don't lose heart when you do not clear the exam in the first attempt itself.

Hi Kunal,
Both the colleges are very good for CSE.
NIT Trichy comes in the ranking of top NITs of India and BITS Pilani is the premier private engineering institute. However, when it comes to CSE, BITS Pilani certainly has an edge over NITT. BITS has its flagship course as CSE which is at par with the top IITs like IIT Delhi, Bombay, etc. The kind of environment and peer-learning which you get at BITS Pilani is simply phenomenal. The campus life of BITS Pilani is one of the best in India and flexibility of electives is obviously there. If I talk about placements, BITS Pilani CSE has the best placements among all other courses. Some companies are Google, Microsoft, Amazon, Adobe, etc. Many students jump out of their core CSE profile and get into a consulting role at McKinsey or Goldman Sachs. So, I would suggest go for BITS Pilani. However, If money is an issue, you should join NITT. Best wishes.
