About
JNCIS-DC is the specialist-level certification in the Juniper data center track, designed for networking professionals with intermediate knowledge of Juniper Apstra, IP Fabric design, and modern data center architectures (EVPN-VXLAN). Candidates must hold current JNCIA-Junos before attempting this exam. The certification validates understanding of Apstra workflows, overlay/underlay fabric design, QFX series switches, multitenancy, intent-based analytics, and data center interconnect patterns.
Domain context — Networking / Data Center
Data center architecture and operations — the design, deployment, and troubleshooting of IP fabrics, overlay networks, and Apstra-orchestrated infrastructure. JNCIS-DC focuses on Juniper's Junos and Apstra ecosystem in hyperscale and enterprise data center environments.
