JNCIS (ENT) Training

Juniper Networks Certified Internet Specialist (ENT) – JNCIS ENT Training

The Juniper Networks Certification Program (JNCP) Enterprise Routing and Switching track allows participants to demonstrate competence with Juniper Networks technology. Successful candidates demonstrate thorough understanding of networking technology in general and Juniper Networks enterprise routing and switching platforms.

This course provides students with intermediate routing knowledge and configuration examples. The course includes an overview of protocol-independent routing features, load balancing and filter-based forwarding, OSPF, BGP, IP tunneling, and high availability (HA) features.

Through demonstrations and hands-on labs, students will gain experience in configuring and monitoring the Junos OS and monitoring device operations. This course uses Juniper Networks SRX Series Services Gateways for the hands-on component, but the lab environment does not preclude the course from being applicable to other Juniper hardware platforms running the Junos OS.

JNCIS-ENT exam topics are based on the content of the recommended instructor led training courses, as well as the additional resources.
