Which two features are characteristics of software-defined networks when compared to traditional infrastructure? (Choose two.)

Configuring devices "box-by-box" is a hallmark of traditional network infrastructure where each device is individually accessed and managed, contrasting with the centralized, programmatic control of SDN.

Manual changes are characteristic of traditional networks, whereas SDN aims to automate network operations and configuration through centralized controllers and APIs, minimizing manual intervention.

Software-defined networks (SDN) commonly employ overlay networks, such as VXLAN or NVGRE, to create virtual network segments that run on top of the physical underlay. This approach provides greater flexibility, logical separation, and simplified network segmentation compared to traditional methods.

SDN is fundamentally designed for change, emphasizing agility, programmability, and automation to adapt quickly to business needs. Network modifications, policy updates, and resource provisioning are orchestrated centrally through software, making the infrastructure inherently dynamic and responsive.

While advanced SDN deployments can benefit from scripting and API interaction, managing an SDN through its controller GUI or automation tools does not inherently require extensive software development experience for day-to-day operations, making it not a universal characteristic compared to traditional infrastructure.
