Juniper is awesome in a lot of ways, but one of them is the free training, labs, and exam discounts they offer. If you're new to the technology I'd highly recommend taking advantage of these programs. I've put together a video that walks through all of their resources. In the video I discuss the Juniper Networks certifications, their free training (through Junos Genius) & labs (Juniper vLabs), and their discounted exam vouchers (75% off) that they all offer for you. It's really a great opportunity for folks who are just getting into networking to have the opportunity to go after some certifications on some technology that's really relevant in the industry.
There are 5 different Juniper associate certifications that cover different areas.
Don't forget about the new Mist track too, brings them up to 6 JNCIA's :-D
I know!!! When I started making these videos, the JNCIA-Mist cert hadn't come out. I just passed my JNCIA-DevOps this morning, so I guess I should look into Mist, haha.
