A security team is reviewing the SDN controller's security posture. They are concerned about the northbound API being a potential attack vector. Which measure should they implement to mitigate this risk?

Disable the northbound API and use only the CLI

Use TLS encryption and strong authentication for all northbound API traffic

Allow the API to be accessed from any network

Use only basic authentication without encryption

An SDN controller is unable to communicate with a switch. What is the first step to troubleshoot this issue?

Verify network connectivity between the controller and the switch

Reinstall the controller software

Replace the switch with a new one

A service provider is deploying an SDN controller to manage a multi-tenant OpenStack cloud. Each tenant requires isolated L2 segments that must span multiple hypervisor hosts. The team plans to use VXLAN overlays for tenant isolation. Which SDN architectural component is primarily responsible for translating the OpenStack Neutron API calls into the VXLAN tunnel configuration pushed to the hypervisor vSwitches?

The VXLAN VTEP on the physical ToR switch

The SDN controller's northbound API plugin for Neutron

The OpenStack Neutron DHCP agent

What is a key benefit of integrating an SDN controller with a cloud management platform?

It guarantees zero network latency

It removes the need for network security policies

It allows network services to be provisioned automatically as part of cloud orchestration

It eliminates the need for physical network switches

A DevOps team wants to automate the deployment of network policies using a CI/CD pipeline. The team plans to use the SDN controller's northbound API to push configuration changes. Which capability of the northbound API is most important for this automation use case?

Ability to translate between VXLAN and NVGRE

Programmatic access via RESTful APIs
