Is it enough that completing a CCNA course can place me, or do I have to definitely write a CCNA exam?

Hi Vishnu, You should need a CCNA to get a job even in networking. However, for certain situations like working for a Cisco certified partner, this is a requirement. So in this case, you need to take the exam and not just the course. Hope this information helps. Please feel free to revert. Wish

Having knowledge you can not prove yourself whether you know or not till you get succeed to reach out interview seat. Being a Global Certifications you will sure get chance to sit in interview chair. Once you sit in interview chair then you will have justify your knowledge. Regards
