A network architect is designing a new solution that uses a centralized controller to manage both wired and wireless network infrastructure across multiple sites. The goal is to simplify policy enforcement, automate provisioning, and provide a single point of management. Which type of SDN solution is best suited for this comprehensive, enterprise-wide approach?
- AOpenFlow-based SDN
- BController-based Overlay SDN
- CIntent-Based Networking (IBN)
- DSD-WAN (Software-Defined Wide Area Network)
Show answer & explanationAnswer & explanation
Correct answer: C. Intent-Based Networking (IBN)
Intent-Based Networking (IBN) represents an advanced evolution of SDN, focusing on translating business intent into network policies and automatically configuring the network to achieve that intent, constantly verifying compliance. It's ideal for a comprehensive, enterprise-wide approach to policy enforcement and automation across various infrastructure types.
Why the other options are wrong
- A. OpenFlow is a protocol used in some SDN implementations, but not an end-to-end solution for enterprise-wide intent-based management.
- B. Controller-based Overlay SDN focuses on virtualizing the network on top of existing physical infrastructure, primarily for data center or cloud environments, but IBN goes beyond this by focusing on business intent.
- D. SD-WAN focuses specifically on optimizing and managing WAN connections, not the entire wired and wireless campus infrastructure with comprehensive policy enforcement.
Intent-Based Networking (IBN)
An advanced networking approach that captures business intent and translates it into network policies, automatically configuring and continuously verifying the network to achieve and maintain that desired state.
- Focuses on business intent, not low-level configurations
- Automates configuration and policy enforcement
- Continuously verifies network compliance
Memory trick: SDN evolves from protocols to intent.
