Implementing Cisco Application Centric Infrastructure (300-620 DCACI)

As organisations accelerate their digital ambitions, the data center has become the engine room of business innovation. New applications must be launched quickly, workloads must move freely between physical and virtual environments, and security must be enforced consistently without slowing operations. Meeting these expectations requires a network that is guided by intent and policy rather than by manual, box-by-box configuration.

Cisco Application Centric Infrastructure (Cisco ACI) delivers exactly this capability. It brings the principles of software-defined networking to the data center, enabling administrators to describe how applications should communicate and allowing the fabric to enforce those rules automatically. The Implementing Cisco Application Centric Infrastructure (300-620 DCACI) course provides a comprehensive, hands-on understanding of how this application-centric networking model is designed, deployed, and operated.

Learners begin with the foundations of the Cisco ACI fabric: its spine-and-leaf architecture, the hierarchical object model and the Application Policy Infrastructure Controller (APIC), which acts as the central point of policy, automation and visibility. From there, the course explores the logical constructs that give ACI its power, including tenants, VRFs, bridge domains, application profiles, endpoint groups and contracts. Learners also examine how the fabric discovers new switches, how endpoints are learned, how external networks and virtualization platforms are integrated, and how the environment is monitored, secured, and maintained.

With its clear alignment to the 300-620 DCACI exam, this Cisco DCACI training equips network and data center professionals to deliver consistent application connectivity, streamlined data center automation and resilient, scalable data center infrastructure.

Course Objectives

Participants who complete this Cisco ACI training will be able to:

• Explain the Cisco ACI fabric architecture, its hardware and topology, and how the APIC centralises policy and management.
• Build the ACI logical policy model using tenants, VRFs, bridge domains, application profiles and endpoint groups.
• Control application communication through contracts and filters, and apply vzAny, preferred groups and endpoint security groups where appropriate.
• Implement fabric and access policies that connect servers, hypervisors, and other devices to leaf switches.
• Configure bridge domain forwarding settings and explain how the fabric learns and tracks endpoints.
• Extend the fabric to external networks through Layer 2 connections and L3Out, and integrate VMware vCenter and Nutanix virtual environments.
• Use faults, events, health scores, and monitoring tools to maintain fabric health and troubleshoot connectivity and policy issues.
