A company is planning to expand its network across multiple geographic locations and requires a scalable and flexible networking solution that can manage diverse traffic types efficiently while also allowing centralized management. Which technology would be most appropriate for its needs?
A software-defined wide area network (SD-WAN) is designed to extend enterprise networks over large geographic areas. It provides centralized control, enhanced security, improved bandwidth utilization, and support for multiple connection types such as MPLS, broadband, and LTE/5G. By using a centralized controller to direct traffic intelligently across all available paths, SD-WAN simplifies WAN operations, boosts performance, and can reduce costs.
IPv6 addressing merely defines a new IP-address format and does not provide centralized WAN management. A virtual private network (VPN) creates secure tunnels but lacks the dynamic, centralized orchestration and path selection of SD-WAN. Zero Trust Architecture (ZTA) is a security framework focused on continuous verification rather than WAN transport and management. Therefore, SD-WAN is the most appropriate choice.
