Suggested answer: A

Explanation:

Definition of SD-WAN:

Software-Defined Wide Area Network (SD-WAN) is a technology that simplifies the management and operation of a WAN by decoupling the networking hardware from its control mechanism. It allows for centralized management and enhanced security.

Benefits of SD-WAN:

Reduced Provisioning Time: SD-WAN enables quick and easy deployment of new sites with centralized control and automation.

Security: Incorporates advanced security features such as encryption, secure tunneling, and integrated firewalls.

Scalability: Easily scales to accommodate additional sites and bandwidth requirements.

Comparison with Other Technologies:

VXLAN (Virtual Extensible LAN): Primarily used for network virtualization within data centers.

VPN (Virtual Private Network): Provides secure connections but does not offer the centralized management and provisioning efficiency of SD-WAN.

NFV (Network Functions Virtualization): Virtualizes network services but does not specifically address WAN management and provisioning.

Implementation:

SD-WAN solutions are implemented by deploying edge devices at each site and connecting them to a central controller. This allows for dynamic routing, traffic management, and security policy enforcement.
