What is a key feature of the assurance element of the intent-based networking model?

• A. End to end Verification of network
• B. Partial verification of individual devices
• C. Manual auditing of configurations
• D. No verification required

Answer: (A)

Assurance in intent-based networking focuses on confirming that the network behavior actually matches the declared intent across the entire path. The best feature is end-to-end verification of the network, meaning continuous validation from source to destination across all devices and domains to ensure policies, configurations, and performance align with the desired state. It handles policy enforcement, reachability, QoS, and security requirements and can trigger remediation when drift is detected. This approach is far more effective than verifying only individual devices, which can miss issues that arise when traffic traverses multiple devices, and than manual audits or no verification, which are slower or ineffective.
