Skills measured
ACI Architecture & Core Concepts
This skill focuses on the foundational principles of Cisco ACI, including its leaf-spine architecture, centralized policy model, and the role of the APIC (Application Policy Infrastructure Controller). Understanding this area is critical for professionals to grasp how ACI simplifies complex data center networking through abstraction and automation. Questions here validate knowledge of how ACI components interact to deliver scalable, resilient, and programmable network infrastructure, forming the basis for all other ACI features and functions.
Tenants, VRFs, and Bridge Domains
This skill area covers the multi-tenancy model in ACI, allowing logical separation of network environments using Tenants, Virtual Routing and Forwarding (VRFs), and Bridge Domains. These constructs are essential for designing isolated and secure application environments within a shared physical infrastructure. Mastery of this area ensures that candidates can correctly design logical topologies that meet customer requirements, enforce segmentation, and facilitate application connectivity while maintaining control and compliance boundaries.
Fabric Discovery, Initialization & Topology
This skill focuses on the procedures and protocols involved in the initial discovery and setup of the Cisco ACI fabric. It covers zero-touch provisioning, node registration, switch role assignments (spine/leaf), and fabric topology validation. Mastery in this area is essential to ensure reliable onboarding of new devices and correct configuration of underlay networks. Candidates who understand this area can efficiently scale the ACI fabric and troubleshoot onboarding issues, which is foundational for any deployment or expansion project.
Security & Microsegmentation
Security in ACI is primarily policy-driven and includes microsegmentation capabilities that allow enforcement at the workload level. This skill area examines the use of whitelist-based communication, isolation within and across EPGs, and integration with external security tools. Proficiency here ensures candidates can implement zero-trust networking principles and minimize attack surfaces in modern data centers. This is crucial for organizations prioritizing compliance, workload protection, and secure multitenant environments.
EPGs, Contracts & Filters
Endpoint Groups (EPGs), Contracts, and Filters are central to the ACI policy model. EPGs group endpoints requiring similar policies, while Contracts define permitted interactions, and Filters control traffic at the protocol and port level. This skill area assesses a candidate’s ability to enforce granular control over inter-application communication, enhancing both security and operational clarity. Understanding these elements is key to implementing scalable, service-aware networking policies without depending on legacy IP-based controls.
Automation & APIs (Python, Ansible, REST, JSON)
Cisco ACI is built for automation, and this skill area evaluates proficiency with tools and languages such as Python, REST APIs, JSON payloads, and Ansible modules. Candidates are tested on their ability to automate repetitive tasks, enforce compliance, and integrate ACI with CI/CD pipelines. Mastery in this area is critical for modern network engineers, enabling them to achieve operational efficiency and maintain large-scale infrastructures through scripting and policy-as-code approaches.
Application Profiles & Policy Modeling
Application profiles in ACI encapsulate how applications are structured across tiers (e.g., web, app, database) using endpoint groups and contracts. This skill evaluates the ability to create reusable, modular, and scalable policies that align with application requirements. It ensures candidates understand how to define logical relationships between workloads while maintaining security and visibility. This abstraction model is a major differentiator for ACI, allowing infrastructure to adapt quickly to changing application needs with minimal reconfiguration.
ACI External Connectivity (L2/L3 Out)
This skill area evaluates how ACI connects to external networks through Layer 2 and Layer 3 Out configurations. It includes static and dynamic routing, use of BGP/OSPF, and route filtering. Understanding this area is vital for ensuring that the ACI fabric can effectively integrate with existing enterprise or cloud networks. It also supports advanced configurations such as shared services and transit routing between tenants, making it fundamental for hybrid or complex environments.
L4–L7 Services Integration
L4–L7 service integration allows insertion of external services like firewalls, load balancers, and intrusion prevention systems into the ACI policy model using service graphs. This area is essential for understanding how ACI handles service chaining and policy-based redirection. It ensures that candidates can configure and manage service appliances in both managed and unmanaged modes, improving network agility and enforcing consistent security or traffic policies across diverse workloads.
ACI Fabric Access Policies
This area covers the modular building blocks used to configure access ports in the ACI fabric, including interface policies, switch profiles, VLAN pools, and domain associations. It's crucial for setting up physical and virtual connectivity between ACI and servers or external networks. Understanding access policy chaining helps reduce configuration errors and promotes reusability. Candidates who master this can design efficient and consistent port configurations that support dynamic workload mobility and VMM integration.
Virtualization & VMM Integration
Virtual Machine Manager (VMM) integration allows ACI to dynamically learn and manage virtualized workloads, typically through integration with VMware vCenter or Microsoft SCVMM. This skill evaluates the configuration of VMM domains, dynamic EPG attachment, and automated port group creation. Proficiency in this area ensures seamless visibility and policy enforcement across virtual workloads, enabling microsegmentation, automation, and faster provisioning in hybrid environments. It’s vital for environments heavily reliant on virtualization or private cloud infrastructure.
Operations, Monitoring & Troubleshooting
This domain tests knowledge of ACI’s built-in operational tools and methodologies, including fault severity, health scores, fabric diagnostics, and monitoring dashboards. Candidates are expected to demonstrate a systematic approach to troubleshooting common ACI issues, ensuring network reliability. Proficiency in this area reduces downtime, enhances visibility, and allows engineers to take proactive measures using tools like Visore, CLI commands, and API logs, all essential in enterprise-scale deployments.
Upgrades, Backups & Disaster Recovery
This area addresses procedures for upgrading the ACI fabric (both switches and APICs), performing configuration backups, and preparing for disaster recovery. Questions assess the ability to perform non-disruptive upgrades, understand the snapshot architecture, and roll back to previous states when needed. Mastery of this skill ensures high availability and business continuity, especially in mission-critical environments where configuration integrity and controlled change management are paramount.
Cisco ACI Multi-Site & Multi-Pod
This skill focuses on large-scale ACI deployments spanning multiple locations or data center pods. It includes understanding the architectural differences between Multi-Pod and Multi-Site, inter-site communication policies, ISN configuration, and tenant extension. Candidates are tested on the ability to extend policy, maintain operational consistency, and ensure fault isolation across geographically distributed infrastructures. Mastery is essential for enterprises seeking high availability, disaster recovery, or global application presence.
Enhancements & Advanced Topics
This evolving skill area covers recent innovations in Cisco ACI such as ACI Anywhere (cloud extensions for AWS/Azure/GCP), enhanced telemetry, integration with Cisco Nexus Dashboard, and support for emerging protocols or hybrid architectures. It ensures candidates stay current with the latest capabilities, including Infrastructure as Code (IaC), intent-based networking, and enhanced policy analytics. Proficiency here reflects an up-to-date understanding of ACI’s future direction and prepares candidates for modern, hybrid, and cloud-native network operations.
