Final answer:
In Cisco's Software-Defined Access architecture, Applications and Scripts are typically located north of the DNA Center controller. These components interface with the DNA Center for automation and analytics, while the overlay network, underlay network, and fabric are part of the data and control plane operations.
Step-by-step explanation:
Within Cisco's Software-Defined Access (SDA) architecture, the DNA Center controller is the central orchestration and management point. When you refer to the components 'north' of this controller, you are discussing elements that are part of the management plane or application layer, which interact with DNA Center to provide automation, analytics, and integration with other systems.
The correct components typically located north of the DNA Center controller are:The overlay network, underlay network, and fabric are all parts of Cisco's SDA architecture but they are not positioned 'north' of the DNA Center. They relate more to the data plane and control plane of network operations, which are essentially 'south' of the DNA Center in the typical network topology model.The Cisco Software-Defined Access (SDA) solution consists of several components, including the DNA Center controller, overlay network, underlay network, fabric, applications, and scripts. The DNA Center controller, which is the central management platform, is typically located north of the other components in the network architecture. It provides a single point of control for the entire SDA solution. The overlay network, underlay network, fabric, applications, and scripts are typically located in the southbound direction of the network, connecting to the DNA Center controller.
