Implementing Cisco Application Centric Infrastructure (300-620 DCACI)

As organisations invest in modern data centers to support growing digital services, the skills needed to run those environments are changing. Network professionals are no longer measured only by their ability to configure individual switches. They are increasingly expected to design consistent policies, automate repetitive tasks, and ensure that applications remain connected and secure as the infrastructure scales. This evolution has made software-defined networking (SDN) an essential competency for anyone working in the data center.

Cisco Application Centric Infrastructure (Cisco ACI) is one of the most widely adopted platforms for bringing these principles into practice. The Implementing Cisco Application Centric Infrastructure (300-620 DCACI) course provides a comprehensive and carefully structured introduction to the technology, guiding learners from the fundamentals of the fabric to the practical tasks involved in operating it.

Learners first develop a clear understanding of the Cisco ACI architecture, including the spine-and-leaf fabric, the hierarchical object model, and the Application Policy Infrastructure Controller (APIC). They then learn how the policy model brings order and consistency to the network through tenants, VRFs, bridge domains, application profiles, endpoint groups (EPGs), and contracts. As the course progresses, learners explore fabric discovery, access policies, endpoint learning, external connectivity, network virtualization integration and Layer 4–7 services, before turning to monitoring, backup, access control and upgrades.

Aligned with the 300-620 DCACI exam, this Cisco DCACI training gives professionals a firm command of policy-based networking and the confidence to support reliable, efficient and future-ready data center infrastructure.

Course Objectives

The course is designed to help learners:

• Describe the components of the Cisco ACI fabric, the APIC, the ACI object model, and the process by which new switches are discovered.
• Configure the logical policy model, including tenants, VRFs, bridge domains, application profiles, and EPGs.
• Secure application communication using contracts, filters, vzAny, preferred groups, and endpoint security groups.
• Implement access policies, vPCs and interface configurations to connect bare-metal servers and hypervisors to the fabric.
• Explain endpoint learning and configure bridge domain settings such as unicast routing, Layer 2 unknown unicast handling, and ARP flooding.
• Establish external Layer 2 and Layer 3 connectivity and integrate the fabric with virtualization platforms and service appliances.
• Manage and monitor the fabric using health scores, faults, syslog, SNMP, configuration backups, AAA, and RBAC, and troubleshoot common issues.
