YES and YES !

the CCNA is definitely worth it — it’s one of the best certifications a network administrator could earn at any point in their career. The CCNA is worth it because Cisco technology provides service provider and enterprise router solutions to nearly 40% of the world. Of course, there are plenty of non-Cisco networks, but there’s basically no other certification that can all at once prepare you for all the devices and jobs that the CCNA does.
