WGU D415 SOFTWARE DEFINED
NETWORKING PA AND OA FINAL PAPER
2026 FULL QUESTIONS WITH CORRECT
ANSWERS GRADED A+
⩥ What are traditional networking devices? Answer: Hardware-based
devices like switches and routers that perform specific tasks related to
data movement and decision-making.
⩥ What are the two main jobs of traditional networking devices?
Answer: Moving data through the network and deciding how the data
moves through the network.
⩥ What is the data plane in networking? Answer: The part of the
network responsible for moving data.
⩥ What is the control plane in networking? Answer: The part of the
network responsible for deciding how data moves through the network.
⩥ How does SDN improve network management? Answer: By
centralizing control and allowing software to manage devices, reducing
complexity and vendor-specific issues.
, ⩥ What role does the application play in SDN? Answer: It is used by
administrators to configure network devices and monitor traffic.
⩥ What is the function of the controller in SDN? Answer: It processes
commands from the application and translates them into configurations
for physical devices.
⩥ What type of communication occurs between the application and
physical devices in SDN? Answer: Two-way communication, where the
application sends commands and receives statistical data.
⩥ What is application awareness in SDN? Answer: The ability of the
network to prioritize traffic based on the specific application making the
request.
⩥ What is zero-touch provisioning? Answer: The capability to configure
network devices remotely without manual intervention.
⩥ What does transport agnosticism mean in the context of SDN?
Answer: The independence from specific transport or network layer
protocols, allowing for more flexible routing decisions.
⩥ What is the significance of centralized policy management in SDN?
Answer: It reduces errors that can occur from manual configurations and
ensures consistency across the network.
