Which two capacities of Cisco DNA Center make it more extensible as compared to traditional campus device management? (Choose two)

A. adapters that support all families of Cisco IOS software

B. SDKs that support interaction with third-party network equipment

C. customized versions for small, medium, and large enterprises

D. REST APIs that allow for external applications to interact natively with Cisco DNA Center

E. REST APIs that allow for external applications to interact natively with Cisco DNA Center

B.   SDKs that support interaction with third-party network equipment
D.   REST APIs that allow for external applications to interact natively with Cisco DNA Center

Explanation:

Cisco DNA Center offers 360-degree extensibility through four distinct types of platform capabilities:

+ Intent-based APIs leverage the controller and enable business and IT applications to deliver intent to the network and to reap network analytics and nsights for IT and business innovation.
+ Process adapters, built on integration APIs, allow ntegration with other IT and network systems to streamline IT operations and processes.
+ Domain adapters, built on integration APIs, allow integration with other infrastructure domains such as data center, WAN, and security to deliver a consistent intent-based infrastructure across the entire IT environment.
+ SDKs allow management to be extended to third-party vendor’s network devices to offer support for diverse environments.
