In an SDN switch, where are the forwarding rules that determine packet handling stored?

In the routing table of the host

An SDN controller is being deployed in a data center. The team wants to ensure that the controller can manage both OpenFlow-enabled switches and devices that only support NETCONF. What is the best approach?

Replace all NETCONF devices with OpenFlow-enabled switches.

Configure the NETCONF devices to emulate OpenFlow.

Use a controller that supports multiple southbound protocols.

Use a separate controller for each protocol.

A network architect is designing an SDN solution for a large enterprise. The architect wants to ensure that the solution can scale to support thousands of switches and handle a high volume of flow requests. Which consideration is most important for the controller design?

High availability and clustering of controllers

Placing the controller in the data plane for faster processing

Disabling proactive flow entries to reduce controller load

Using a single controller to avoid complexity

What is a primary function of the SDN controller in a software-defined network?

Providing physical connectivity between devices

Maintaining a global network topology and computing paths

Forwarding packets at line rate

An SDN controller is being deployed in a multi-vendor environment. Some switches support OpenFlow, while others only support NETCONF. The network team wants to use a single controller to manage all devices and also provide a REST API for custom applications. What is the most practical approach?

Use NETCONF for all devices and ignore OpenFlow.

Deploy two separate controllers, one for each protocol, and do not provide a northbound API.

Use OpenFlow for all devices and disable NETCONF.

Select a controller that supports both OpenFlow and NETCONF as southbound protocols and exposes a northbound REST API.

SDN Architecture JN0-214 Practice Questions (Page 5)

Part of the Cloud Infrastructure (NFV and SDN) domain, which makes up ~19% of our current practice bank. Juniper Networks does not publish an official question count, but from its 90-minute exam (~35–60 total, ~7–11 in this domain), expect 1–2 from this objective — we provide 32 practice questions to prepare you well beyond it.
