Juniper Networks Certified Internet Specialist - E-Series

The JNCIS-E exam is designed for networking professionals with advanced knowledge of, and experience with, the Juniper Networks E-series platforms. The JNCIS-E exam tests for a wider and deeper level of knowledge than does the JNCIA-E exam. Sources of question content include the E-series platforms documentation set, on the job product experience, as well as the understanding of Internet technologies and design principles considered to be common knowledge at the Specialist level. Passing the JNCIS-E exam is a prerequisite for attempting the JNCIP-E practical exam.
