Learning networking technologies for the first time can seem like a daunting task. From subnetting to spanning trees, there is a lot to study and understand. Our CCNA training lays it all out for the new network professional. The course is both broad and deep, covering important topics in a way that prepares you for the challenging CCNA exams.
The technologies associated with Cisco routing and switching have been around for a long time now. But in the fast-paced telecommunications industry, a good deal of the technology changes every year. That’s why Cisco requires regular recertification for CCNA professionals. CCNA training will help experienced professionals refresh their skills and prepare for recertification.

384. Which two capabilities of Cisco DNA Center make it more extensible? (Choose two.)
A. REST APIs that allow for external applications to interact natively with Cisco DNA Center
B. adapters that support all families of Cisco IOS software
C. SDKs that support interaction with third-party network equipment
D. modular design that is upgradable as needed
E. customized versions for small, medium, and large enterprises
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 insights for IT and business innovation.
Process adapters, built on integration APIs, allow integration 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.
