An SDN controller is configured to use NETCONF to manage a set of network devices. The controller reports that it cannot establish a NETCONF session with one of the devices. The device is reachable via ping. Which configuration detail is most likely causing the issue?

The device's management interface is down

The device does not have a default gateway

The device is configured to use SSH on a non-default port for NETCONF

The device is using OpenFlow instead of NETCONF

How does an SDN controller typically integrate with a cloud management platform like OpenStack?

By serving as the primary storage backend for virtual machines

By acting as the networking backend for the cloud platform's virtual network service

By replacing the cloud platform's compute service

By directly managing the hypervisor's CPU scheduling

What is the primary purpose of northbound APIs in an SDN architecture?

To provide a secure channel for encrypting all network traffic

To replace the need for a control plane in the network

To enable applications and orchestration platforms to programmatically interact with the SDN controller

To allow the controller to communicate with network devices

In an SDN architecture, which component is responsible for executing the forwarding decisions on packets?

The data plane (network devices)

A company is deploying an SDN controller in a brownfield environment with existing network infrastructure. The existing switches do not support OpenFlow. The team wants to manage these switches centrally. Which approach should they take?

Disable the SDN controller and manage the switches manually

Install OpenFlow agents on the existing switches

Use a gateway that translates the controller's commands to the switches' native management protocols

Replace all existing switches with OpenFlow-capable hardware
