Implementing Cisco Application Centric Infrastructure (300-620 DCACI)

Cisco Application Centric Infrastructure (Cisco ACI) closes that gap by making the application the organising principle of the network. Through a centrally managed, policy-driven fabric, it allows organisations to define connectivity and security once and to enforce them consistently across physical and virtual workloads. The Implementing Cisco Application Centric Infrastructure (300-620 DCACI) course provides a thorough and practical understanding of how this application-centric networking model works and how it is implemented in real environments.

The course begins with the architecture of the Cisco ACI fabric and the central role of the Application Policy Infrastructure Controller (APIC). Learners then master the logical constructs at the heart of ACI, namely tenants, VRFs, bridge domains, application profiles, endpoint groups and contracts, and learn how they combine to deliver clear, enforceable policy. The programme continues through fabric discovery, access policies, packet forwarding, external connectivity, network virtualization integration and service graphs, and concludes with the monitoring, management and troubleshooting practices that sustain a healthy fabric.

Aligned with the 300-620 DCACI exam, this Cisco DCACI training prepares professionals to bring greater agility, consistency and control to modern data center infrastructure through software-defined networking and data center automation.

Course Objectives

Learners who complete this training will be prepared to:

• Explain the Cisco ACI fabric architecture, its spine-and-leaf design and the centralised management role of the APIC.
• Implement tenants, VRFs, bridge domains, application profiles and endpoint groups to model application connectivity.
• Enforce communication policy between application tiers using contracts, subjects, filters, and related policy options.
• Configure access policies and connect physical and virtual workloads to the ACI fabric.
• Implement external network connectivity through Layer 2 extensions and L3Out, and integrate VMM domains and service graphs.
• Monitor fabric health with faults, events, audit logs, and health scores, and troubleshoot common connectivity and policy issues.
• Apply essential operational practices, including management access, configuration backup, AAA and RBAC, and software upgrades.
