Overview of the Data Center Design, Specialist (JNCDS-DC) Exam
The JNCDS-DC certification targets network architects and design engineers responsible for architecting scalable, resilient data center infrastructures using Juniper Networks hardware. Candidates must demonstrate proficiency in designing underlay and overlay architectures, specifically leveraging VXLAN with EVPN-MPLS or EVPN-VXLAN control planes. Technical mastery requires evaluating high-availability features, data center interconnect methodologies, security segmentation, and traffic engineering through Junos OS features. Design assessments emphasize integrating multi-vendor ecosystems, managing physical and logical topology scaling, and implementing automation frameworks. Proficiency includes optimizing underlay routing protocols like OSPF and BGP for non-blocking fabric performance while ensuring multi-tenant isolation, precise latency management, and robust infrastructure monitoring capabilities.
