What is JNCIA-DC?

The Data Center track enables you to demonstrate competence with data center technologies and related configuration and troubleshooting skills. JNCIA-DC, the associate-level certification in this track, is designed for data center networking professionals with introductory-level knowledge of the Juniper Networks Junos software and data center devices.

The written exam verifies your understanding of data center technologies, related platform configuration, and troubleshooting skills.

IJDCN - Introduction to Juniper Data Center Networking

This course lays the foundational knowledge necessary to understand a data center that is built upon an IP fabric, but does not include Ethernet VPN–Virtual Extensible LAN (EVPN-VXLAN) architecture.

This course covers Ethernet switching, VLANs, Layer 2 security features, routing policies, link aggregation, load balancing, filter-based forwarding (FBF), routing instances, BGP, graceful restart, and bidirectional forwarding detection (BFD).
