A large e-commerce company is experiencing inconsistent application performance during peak shopping seasons. The network team suspects that the issue stems from inefficient traffic management and lack of granular visibility into application flows across its distributed data centers and public cloud infrastructure. Which network architecture principle, when properly implemented, would most effectively address these challenges?
- AFlat Layer 2 network design
- BIntent-based networking with end-to-end visibility
- CNetwork segmentation with microsegmentation capabilities
- DStrict hierarchical Layer 3 design
Show answer & explanationAnswer & explanation
Correct answer: B. Intent-based networking with end-to-end visibility
Intent-based networking (IBN) with end-to-end visibility provides the automation, analytics, and granular control needed to understand and manage application flows across hybrid environments. It allows the network to constantly align with business intent, proactively identify performance issues, and optimize traffic, directly addressing the challenges of inconsistent performance and lack of visibility.
Why the other options are wrong
- A. A flat Layer 2 network would exacerbate, not solve, issues with inefficient traffic management and lack of granular visibility in a distributed environment.
- C. Network segmentation with microsegmentation is crucial for security and compliance but does not inherently provide the comprehensive traffic management and end-to-end performance visibility needed for application optimization across distributed data centers and public cloud.
- D. A strict hierarchical Layer 3 design provides structure but lacks the dynamic, application-aware intelligence and automation required for granular visibility and proactive performance optimization across hybrid cloud.
Intent-Based Networking (IBN)
A network management paradigm that uses machine learning and automation to translate business intent into network policies, constantly monitors the network to ensure intent is met, and proactively takes corrective action.
- Translates business intent into network configuration.
- Continuous validation and assurance of network state.
- Automated policy enforcement and dynamic adjustment.
- Requires end-to-end visibility and analytics.
Memory trick: Performance: Intent is Key to Visibility and Efficiency.
