AI systems are rapidly transforming how organizations operate, but they also introduce new and evolving security risks. This learning path focuses on how Cisco AI Defense enables organizations to secure AI systems across their entire lifecycle. You will develop an understanding of common AI vulnerabilities and how they impact modern environments, while exploring how Cisco AI Defense provides visibility into AI assets, validates models against adversarial risks, and enforces real-time protections through runtime guardrails. By the end, you will have a clear understanding of how Cisco AI Defense delivers visibility, validation, and runtime protection to help secure AI at scale.

This learning path on foundational Enhanced Interior Gateway Routing Protocol (EIGRP) provides a comprehensive introduction and deep dive into the core aspects of EIGRP. It starts by explaining the basics of EIGRP, including its purpose, operation, and fundamental concepts such as EIGRP Neighbors, advertising routes, authentication, and many others. This learning path aims to equip network professionals with the knowledge needed to manage and optimize EIGRP in real-world environments, emphasizing best practices and common pitfalls.

Cisco has been at the forefront of developing a suite of standalone tools for data center networking, collectively known as the Day 2 Operations Suite. Recently, Cisco has initiated the integration of these tools into a unified interface called NEXUS Dashboard, providing a consolidated view and shared data repositories for enhanced application correlation. This Learning path is designed specifically for those new to networking or new to the NEXUS Dashboard product. Future learning paths will go into more detail about operating and implementing the NEXUS Dashboard platform.

Cisco ACI is a policy-driven CLOS or Spine/Leaf based switching fabric utilizing layer 3 ECMP routing in the underlay and VXLAN encapsulation in the overlay to transport layer two and layer three traffic East/West across the fabric and North/South in and out of the fabric. ACI consists of the Application Policy Infrastructure Controller (APIC), a centralized controller that manages all aspects of the ACI fabric. The leaf switches are ToR switches that provide connectivity between servers and external networks, and the spine switches are Layer 3 switches that provide ECMP high-bandwidth connectivity between leaf switches. An ACI fabric can be expanded East/West by adding leafs, cabling to the spines, and registering them. ACI was designed to operate as "One Big Switch" (like a chassis-based NEXUS 7K) with the controllers acting like the Supervisors, the spines as fabric modules, and leafs acting as blades. This approach allows us to decouple these elements from the chassis and place them anywhere in the data center. The leafs (blades) can be placed anywhere in the data center, so you are not limited to a chassis. We can take this decoupling one step further and put a leaf in a remote data center (remote leaf), place a spine and leaf fabric extension into a second data center (multi-pod), or a new spine-leaf fabric in a data center (multi-site). Using the NEXUS Dashboard Orchestrator (NDO), we can treat multiple fabrics as one entity from a policy standpoint and manage and perform day two operations from a single pane of glass. The power of ACI allows us to stretch layer two and layer three across multiple fabrics and use a single policy for forwarding traffic in the data center. This Learning Module will guide you through basics and implementation skills.
