A network automation engineer is building a system to discover new devices, automatically assign them to appropriate configuration groups, and then apply initial baseline configurations based on their role. This entire process needs to be orchestrated and managed from a central platform. Which type of automation solution is best suited to coordinate these multiple, sequential tasks?

  1. AMonitoring System
  2. BConfiguration Management Tool
  3. CScripting Language (e.g., Python)
  4. DNetwork Orchestrator
Show answer & explanation

Correct answer: D. Network Orchestrator

A Network Orchestrator is designed to coordinate complex, multi-step workflows across various systems and domains. It ties together discovery, classification, and configuration tools into a coherent, automated process, providing a centralized platform for end-to-end automation.

Why the other options are wrong

  • A. A monitoring system primarily collects and analyzes data, it does not actively orchestrate and apply configurations to devices.
  • B. A configuration management tool (like Ansible or Puppet) primarily focuses on applying configurations, but typically doesn't handle the end-to-end orchestration of discovery and classification as its primary function.
  • C. While a scripting language can be used to write individual tasks, it lacks the inherent framework for sequencing, error handling, state management, and overall coordination of a multi-stage, end-to-end automation process.

Network Orchestrator

A Network Orchestrator is a software platform that coordinates and manages complex, multi-step automation workflows across disparate network devices, services, and domains. It integrates various automation tools and systems to achieve end-to-end automation.

  • Coordinates complex workflows
  • Integrates multiple automation tools
  • Manages end-to-end processes
  • Provides centralized control and visibility
  • Often involves state management and error handling

Memory trick: The Orchestrator conducts the automation symphony.
