What feature of SD-WAN allows for management and configuration across devices?

1. Application data routing

2. Central policy management

3. Physical network encapsulation

4. Manual policy adjustments

The correct answer is: Central policy management

Central policy management is a critical feature of SD-WAN (Software-Defined Wide Area Network) that streamlines the management and configuration of network devices. This capability enables administrators to define, implement, and enforce policies from a single centralized interface, making it easy to manage complex networks that span multiple locations and devices. By using central policy management, organizations can quickly adjust configurations, optimize performance, and enforce security policies across all devices in the network, which enhances efficiency and reduces the likelihood of configuration errors that can occur when changes are made manually on individual devices. This centralized approach provides visibility into network performance and traffic, allowing for better decision-making and quicker responses to any issues that may arise. Other options, such as application data routing and manual policy adjustments, focus more on specific functionalities of SD-WAN rather than the overarching management framework provided by central policy management. While physical network encapsulation might relate to how data is transported, it does not pertain directly to the management and configuration processes essential for an SD-WAN environment.
