Which orchestration tool must be used to manage VXLAN fabrics and includes a built-in dashboard and real-time network health summary for managed devices?

Cisco Nexus Dashboard Fabric Controller (NDFC), formerly known as Data Center Network Manager (DCNM), is Cisco's comprehensive management solution for VXLAN EVPN fabrics. It provides a centralized point of control with a graphical user interface that includes a built-in dashboard for topology visualization, configuration automation, and a real-time health summary for all managed network devices. NDFC is specifically designed for the lifecycle management of modern data center fabrics, making it the correct tool for this requirement.

A. Puppet is a general-purpose IT automation and configuration management tool, not a specialized VXLAN fabric controller with a built-in network health dashboard.
B. Ansible is an open-source automation engine used for application deployment and configuration management, lacking the specific, built-in VXLAN fabric management and health summary features of NDFC.
D. Cisco Intersight is a cloud-based management platform primarily focused on Cisco UCS compute and HyperFlex infrastructure, not the primary tool for orchestrating VXLAN network fabrics.
