QuestionQ551

Infrastructure and Automation

What distinguishes device-level infrastructure management from controller-level infrastructure management?

  • A Device-level management uses NETCONF, whereas controller-level management does not support NETCONF to automate the infrastructure.
  • B Controller-level management uses APIs to simplify the developer experience, whereas device-level management uses traditional management protocols.
  • C Controller-level management is more widely supported because it is standards-based, whereas device-level management is proprietary to each vendor.
  • D Controller-level management exposes northbound, southbound, eastbound, and westbound APIs, easing integration with other technologies, whereas device-level management does not use a controller-based API.
Explanation

Controller-level management provides an abstraction layer and API-driven interface for applications and automation, which simplifies how developers work with the infrastructure. Device-level management addresses individual devices through traditional device-management protocols and interfaces. Cisco documents that controllers abstract individual-device details and expose northbound APIs to applications and southbound APIs to managed devices.
