The application network profile is an expression of which Cisco ACI model implementation stage?
- the logical model
- the concrete model
- the hardware model
- the resolved model
Of the available choices, the application network profile is an expression of the logical model stage of the Cisco Application Centric Infrastructure (ACI) model. The application network profile, which is often simply referred to as the application profile, is an object that acts as the container for all other objects in the model; it tiers endpoint groups (EPGs) and represents how they relate to each other. The logical model is typically configured by the user in the Cisco Application Policy Infrastructure Controller (APIC).
The application network profile is not an expression of the resolved model stage of the Cisco ACI model. The resolved model is a stage that is derived by the APIC in abstract from the logical model stage. In other words, the logical model is converted to the resolved model by the APIC. This stage is a lower-level representation of the ACI model than the logical model stage in that it represents how configuration components are sent to the infrastructure when a policy is executed.
The application network profile is not an expression of the concrete model stage of the Cisco ACI model. The concrete model is a stage that is derived from the resolved model in that it represents the ACI model after configuration has been delivered to each endpoint in the fabric. The concrete model is typically created when switches in the ACI model convert the resolved model. However, there are some objects in the logical model that do not require conversion to the resolved model to also be represented in the concrete model. These objects include physical port properties that are already local to a given leaf or port.
The application network profile is not an expression of the hardware model stage of the Cisco ACI model. The Cisco ACI model consists of only three implementation stages. The hardware model is not one of those stages. Instead, concrete objects are consumed by application-specific integrated circuits (ASICs) on hardware.
