DCIT – Troubleshooting Cisco Data Center Infrastructure (DCIT)


The Troubleshooting Cisco Data Center Infrastructure (DCIT) v6.2 course is designed to help students prepare for the Cisco CCNP Data Center certification and for professional-level data center roles. The focus of this skills-building course is troubleshooting of LANs, SANs, Cisco 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. You’ll master the professional-level skills and technologies needed to troubleshoot Cisco data center infrastructure.
