Implementing Cisco Application Centric Infrastructure (300-620 DCACI)

For many years, data center networks were built around individual devices, VLANs and access lists, each configured by hand and maintained through careful documentation. That approach served organisations well when applications were few and change was infrequent. Today, however, application portfolios are larger, release cycles are shorter, and security expectations are higher, and the traditional model can no longer respond with the speed and consistency that businesses require.

Cisco Application Centric Infrastructure (Cisco ACI) represents a fundamental shift in how data center networks are designed and managed. Instead of configuring each switch individually, engineers express the needs of an application as policy, and the fabric applies that policy uniformly wherever the application runs. The Implementing Cisco Application Centric Infrastructure (300-620 DCACI) course offers a clear and authoritative guide to this policy-based networking model and to the practical skills required to implement it.

The course introduces the building blocks of the Cisco ACI fabric, from the spine-and-leaf topology and fabric discovery process to the Application Policy Infrastructure Controller (APIC) and its object model. Learners then explore how tenants, VRFs, bridge domains, application profiles, endpoint groups (EPGs) and contracts work together to deliver secure, application-aware connectivity. The programme also addresses access policies, endpoint learning, external connectivity, network virtualization integration, service graphs and the management practices that keep a production fabric healthy.

Thoughtfully aligned with the 300-620 DCACI exam, this Cisco DCACI training enables professionals to replace complexity with clarity and to build data center infrastructure that is agile, consistent, and ready for growth.

Course Objectives

This course enables learners to:

• Understand the ACI fabric infrastructure, including topology, hardware, the object model, virtual APIC, and the fabric discovery process.
• Design and configure the ACI policy model through tenants, VRFs, bridge domains, application profiles and endpoint groups.
• Define and apply contracts, filters, and related policy constructs to control communication between application tiers.
• Configure access and fabric policies to attach physical servers and virtual hosts to the ACI fabric.
• Implement Layer 2 and Layer 3 external connectivity, VMM integration with VMware vCenter and Nutanix, and service graph insertion.
• Monitor the fabric for faults, events, audit logs, health scores, syslog, SNMP, and Nexus Dashboard Insights, and troubleshoot common issues.
• Maintain the fabric through in-band and out-of-band management, configuration snapshots, AAA and RBAC, and controlled upgrades.
