In terms of infrastructure, the DNA centre is powered by 3 key engines. Which is the correct group?

'Networking' is too broad; DNA Center operates on and manages the network, but it is not one of its internal power engines in the same category as Context and Automation.

While Policy and Context (which is part of Analytics) are central, 'Automation' is a distinct and crucial key engine that is typically emphasized alongside Policy and Analytics.

Cisco DNA Center is powered by three key engines: Policy, which defines network access and behavior; Automation, which streamlines network provisioning and management; and Analytics, which provides deep insights into network performance and security for proactive operations. These engines collectively enable its robust capabilities.

'Encryption' is a security feature that DNA Center might manage or implement across the network, but it is not one of the three foundational engines of its architecture.
