The Data Center track enables you to demonstrate competence with
advanced data center technologies and related configuration and troubleshooting
skills. JNCIE-DC is at the pinnacle of the data center certification track.
The 1-day JNCIE-DC practical exam is designed to validate your
ability to deploy, configure, manage, and troubleshoot Junos-based platforms.
Throughout the 6-hour practical exam, you will build a data center network
consisting of Apstra, vMX, vJunos-switch (vEX), and vQFX Series devices. You will
perform system configuration on all devices including management capabilities, a
Clos IP fabric, EVPN/VXVLAN, DCI, and CoS features.
This track includes one certification:
- JNCIA-DC: Data Center, Associate. For details, see JNCIA-DC.
- JNCIS-DC: Data Center, Specialist. For details, see JNCIS-DC.
- JNCIP-DC: Data Center, Professional. For details, see JNCIP-DC.
- JNCIE-DC: Data Center, Expert. For details, see the sections below.
