A Comprehensive Guide to SD-WAN
What is SD-WAN?
SD-WAN, or Software-Defined Wide Area Network, is a virtual WAN architecture that allows businesses to use any combination of transport services, including broadband internet services, to securely connect users to applications.
Why is SD-WAN important?
SD-WAN is important because it provides simplicity, increased visibility, and fine-tuned control across your WAN, which can significantly decrease costs and improve network performance.
How does SD-WAN work?
SD-WAN—or software-defined networking in a wide area network—simplifies the management and operation of a WAN by separating the networking hardware from its control mechanism.
Exam Tips: Answering Questions on SD-WAN

SD-WAN practice test
Software-Defined Wide Area Network (SD-WAN) is a virtual networking approach that simplifies WAN deployment, management, and operation by decoupling the control and data planes. This allows administrators to make changes more easily through a centralized controller, instead of manually configuring devices one by one. SD-WAN can improve WAN performance by utilizing multiple connection types, including broadband, MPLS, or cellular, and dynamically adjusting the traffic flow based on network conditions. This ensures optimal application performance while reducing costs. Additionally, businesses can centralize functions like WAN optimization, network security, and policy management to streamline network management.
