Which SD‑WAN capability helps a bank improve application experience and meet critical application SLAs?

Quality of Service (QoS) is crucial for banks because it allows them to prioritize critical applications, like core banking transactions or voice over IP, over less time-sensitive traffic. By implementing QoS policies, the SD-WAN can ensure these essential applications receive the necessary bandwidth and low latency, directly improving their performance and helping meet Service Level Agreements (SLAs). This also involves intelligent path selection, where the SD-WAN dynamically chooses the best network path based on real-time conditions to optimize application experience. Integration with PaaS providers is a cloud strategy, not directly an SD-WAN capability for improving application experience or meeting SLAs. BGP is a routing protocol used for exchanging routing information between autonomous systems, but it doesn't inherently provide application prioritization or dynamic path optimization for QoS within an SD-WAN. Implementing a modern core banking system is an application-level upgrade, not an SD-WAN networking capability.
