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.

The JNCIS-E certification is valid for two years. Recertification is achieved by passing the current version of the JNCIS-E exam.

Exam topics include:

Advanced system operation, configuration and troubleshooting, interface configuration, routing protocols (RIP, OSPF, IS-IS, and BGP), MPLS, BRAS, advanced topics including multicast, CoS, advanced policy management, and security.

Note—In cases of identical topics in both the JNCIA-E and JNCIS-E exam, questions are of a more advanced nature on the JNCIS-E exam.
