How Many APICs Can You Communicate with in a Single REST Call?

B.

The APIC (Application Policy Infrastructure Controller) is the centralized management tool for the Cisco Application Centric Infrastructure (ACI). The ACI architecture consists of a spine and leaf topology with switches that are managed by one or more APICs. The REST API is a method of accessing and managing the ACI fabric through a programmable interface.

Postman is a popular REST API client that allows users to make HTTP requests and receive responses. With Postman, users can send REST API requests and receive responses in various formats such as JSON or XML. Postman can be used to interact with the ACI fabric through the REST API.

The question asks how many APICs can be communicated with at one time in a single REST call using Postman. The answer is C: one. Postman sends REST API requests to a single APIC at a time.

While it is possible to send REST API requests to multiple APICs, each request must be sent individually. This is because each APIC manages a specific set of switches and has its own unique state information. Sending a single REST API request to multiple APICs would require synchronization of state information, which is not possible.

In summary, the answer to the question is that Postman can communicate with one APIC at a time in a single REST call.
