Question

Select the correct answer.

Lara is a network administrator who wants to reduce network latency by improving decision-making parameters. She zeroes in on SDN. What must have facilitated this decision?

A.
SDN is agile and dynamically adapts itself to real-time changes.
B.
SDN has improved algorithms to handle decision-making at the hardware level.
C.
SDN provides a decentralized approach to networking.
D.
SDN controller has management provisions through numerous dashboards.

Answer 1

Answer: A

Explanation: Software-Defined Networking (SDN) allows for more dynamic and programmable control over network resources. This includes improved response to changing network conditions, such as adjusting to varying traffic patterns, to minimize latency. This is achieved by decoupling the network's control (decision making) and forwarding (data flow) planes, which allows the network to be programmatically configured. SDN controllers provide centralized control, not decentralized, and they use software applications and policies, not hardware-level algorithms, to direct network traffic. Dashboards can provide useful visuals, but the underlying functionality of SDN is the key factor in facilitating such a decision.
