JNCIP-DC case studies

JNCIP-DC is Juniper's professional-level certification for data center engineers, aimed at people who already hold a JNCIA-DC or have equivalent hands-on experience with Junos and data center fabrics. It sits between the associate and expert tiers, so it assumes you can configure and troubleshoot without step-by-step guidance and can reason about design trade-offs rather than just recall commands. The exam spans six domains: architecture and deployment, switching and fabric technologies (EVPN-VXLAN, MC-LAG, underlay design), routing and overlay networking, security and network services such as firewall filters and tenant separation, automation and orchestration, and monitoring and troubleshooting. Expect scenario-driven multiple choice that describes a topology or symptom in prose and asks for the most likely cause or the correct next step. The JNCIP-DC case studies are 5 cases and about 3,246 words.
