Data Center, Expert (JNCIE-DC)
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 8-hour practical exam, you will build a data center network consisting of multiple MX Series and QFX 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 four certifications:
- 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.
