Post-Deployment and Operations

Verification and Testing

Verification and Testing is a crucial post-deployment phase to confirm the successful implementation and optimal performance of the new Juniper network. This phase involves comprehensive connectivity testing for all devices and users to ensure seamless access to network resources. Rigorous application performance testing validates that critical business applications meet their required bandwidth and latency targets. Security policy enforcement validation is paramount, confirming that all defined access controls, segmentation rules, and threat prevention mechanisms are functioning as intended. Finally, thorough wireless signal strength and coverage validation, often through post-deployment site surveys, will ensure the Wi-Fi network provides ubiquitous and high-quality connectivity across all designated areas.
