Hello
This is a very good question , all of us are looking for certificate which can help us to join international , and famous companies as you mentioned above. CCNA video is very useful to understand Video technology , end points for Video solution , but the experience and on hand experience is the only way to get the best of the jobs . My advise for you study hard read more about solutions which released recently and try to join big projects to get experience and after that all good companies will look for an expert as you.
Thanks
