A company is deploying an SDN controller in a cloud environment. The controller will manage a network that experiences variable traffic loads. The team wants to ensure the controller can handle peak loads without performance issues. Which deployment consideration is most important?

Physical location of the controller

Scalability of the controller cluster

An SDN controller is deployed in a hybrid cloud environment. The controller manages both physical switches in the data center and virtual switches in the cloud. The team wants to use a single controller for both. Which interface configuration is essential to achieve this?

Southbound interface supporting multiple protocols

Northbound interface with REST API

Management interface with SSH access

East-west interface for controller clustering

A company is deploying an SDN controller in a cloud environment. The controller must handle a sudden increase in network events without performance degradation. The team is evaluating whether to scale the controller vertically or horizontally. Which approach is more suitable for this requirement?

Vertical scaling by increasing CPU and memory of a single controller

Disabling topology discovery to reduce load

Using a single controller with a larger database

Horizontal scaling by adding more controller instances

SDN Controller JN0-214 Practice Questions (Page 1)

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 21 practice questions to prepare you well beyond it.
