Which two features describe controller-based networking solutions compared to traditional networking solutions? (Choose two.)
The correct answer is B. reduce network configuration complexity C. provide centralization of primary IT functions. Controller-based SDN solutions centralize network intelligence into a single management plane and automate device configuration, reducing both operational complexity and administrative overhead.

Why each option
Controller-based SDN solutions centralize network intelligence into a single management plane and automate device configuration, reducing both operational complexity and administrative overhead.
Controller-based solutions typically reduce licensing costs by enabling hardware abstraction and commodity switching, not inflate them.
A controller provides a single point of policy definition and pushes consistent configurations to all devices automatically, eliminating the need to manually configure each device individually and thereby reducing configuration complexity.
The SDN controller centralizes the control plane, network visibility, policy enforcement, and provisioning into a unified platform, replacing the distributed, per-device management model of traditional networking.
Fewer network failures is not a guaranteed or defining characteristic of SDN - failures still occur and SDN can introduce new failure points such as controller unavailability.
SDN does not increase bandwidth usage as a defining characteristic - southbound protocol traffic to devices is minimal and does not significantly impact overall network bandwidth.
