A. B. C. D. E.D.
The controller that uses policy-based application profiles is the Cisco Application Policy Infrastructure Controller (APIC).
The Cisco APIC is the centralized controller for the Application Centric Infrastructure (ACI), which provides a policy-based approach to application delivery. The APIC uses policy-based application profiles to define the network, security, and application policies for ACI.
An application profile is a collection of policies that define the requirements of an application. These policies include network policies, such as Quality of Service (QoS) and security policies, such as firewalls and access control lists (ACLs). Application profiles allow network administrators to define application requirements and enforce them consistently across the entire network.
The Cisco APIC uses a declarative model, which means that network administrators define the desired state of the network, and the APIC automatically configures the network to match that state. This approach simplifies network operations and reduces the risk of misconfiguration.
In summary, the correct answer is D. Cisco APIC. The other options, such as OpenStack, Open SDN Controller, OpenFlow Controller, and Cisco UCS Director, do not use policy-based application profiles.
