The Troubleshooting Cisco Data Center Infrastructure (DCIT) v6.0 is a 5-day instructor-led course that introduces learners to the troubleshooting of LAN, SAN, Cisco Data Center Unified Fabric, Cisco Unified Computing System (UCS), and Cisco Application Centric Infrastructure (ACI). The course provides rich, hands-on experience in resolving problems on Cisco MDS switches, Cisco Nexus switches, Cisco fabric extenders (FEXs), Cisco UCS, and Cisco ACI.
The goal of this course is to develop competency in learners to implement data center components such as Cisco Nexus 9000, 7000, 5000, and MDS Switches, as well as the Nexus 2000 Fabric Extenders. The Cisco UCS Servers are covered as well.

The course is designed to help learners prepare for the Cisco CCNP Data Center certification and for professional-level data center roles.


Upon completing this course, the learner will be able to meet these overall objectives:
  • Troubleshoot Layer 2 technologies, such as STP, port channels, vPC, Cisco FabricPath, and FEX
  • Troubleshoot first-hop redundancy, routing, and CFS in the data center
  • Troubleshoot virtualization solutions, such as OTV, VRF, and VXLAN
  • Troubleshoot storage area networks, including Fibre Channel, FCoE, zoning, NPV, and NPIV
  • Troubleshoot data center unified computing
