Which tool is used to navigate the ACI managed objects in real-time?

The correct choice for navigating the ACI (Application Centric Infrastructure) managed objects in real-time is Visore. Visore is an intuitive user interface tool specifically designed for Cisco ACI environments. It enables users to explore and visualize the ACI fabric, providing access to various managed objects, their properties, and relationships.

Visore displays the structure of the ACI fabric in a graphical format, facilitating real-time management and monitoring. It allows network professionals to quickly navigate through different aspects of the ACI configuration, facilitating troubleshooting and analysis of various components within the fabric.

While other tools like Postman and ACI Toolkit are useful for interacting with the ACI API or automating processes respectively, they do not provide the same level of interactive visualization and real-time navigation as Visore. ARYA is a separate tool not directly related to ACI managed objects navigation. Thus, Visore stands out as the most appropriate tool for the specified use case.
