A large enterprise is using an SDN controller to orchestrate network services across multiple sites. The team wants to ensure that if the controller fails, the network can still forward traffic. Which design consideration should the team implement?

Use a single controller to simplify management

Deploy a high-availability controller cluster and configure switches to fall back to local forwarding if the controller is unreachable

Disable the data plane on all switches during a controller failure

Require all switches to be managed by the controller at all times

What is a common strategy for integrating SDN with legacy network devices that do not support southbound protocols like OpenFlow?

Replacing all legacy devices with SDN-compatible hardware

Using a gateway that translates between SDN protocols and legacy device protocols

Connecting legacy devices directly to the SDN controller without any translation

Disabling the control plane on legacy devices

In an SDN environment, how does the controller ensure consistent policy enforcement across devices from different vendors?

By using vendor-specific APIs exclusively

By abstracting device differences and using standard southbound protocols

By manually configuring each device individually

By requiring all devices to be from the same vendor

A company is integrating an SDN controller into an existing data center with a large installed base of legacy switches that only support CLI and SNMP. The team wants to manage these switches centrally without replacing them. Which integration strategy is the most practical?

Disable the SDN controller and manage the legacy switches manually

Install OpenFlow agents on the legacy switches

Use a protocol-translation gateway that converts the controller's intent into CLI or SNMP commands

Replace the legacy switches with SDN-capable hardware
