Can arts student also do CCNA course?

Yes, Arts students can also do this course. Courses like BCA, B-Tech are always helpful in understanding the technology. BUT if you have real interest in networking, good communication skills and passion to work hard then you can ahead. 

I would suggest to do CCNA and then go for CCNP, CCIE level courses as well. Because when you look out for job arts degree might have negative impact but CCIE level knowledge will negate that quite well. 

On Network Bulls faculty, wait anyone from their team to reply. Rest, this was my view.
