How does SDN support Network Functions Virtualization (NFV)?

By providing physical appliances for network functions

By replacing the need for virtual machines

By providing dynamic and programmable network connectivity for virtualized network functions

By eliminating the need for network switches

A company wants to implement a security policy that blocks traffic from specific IP addresses across the entire SDN network. The policy is defined in a security application. How does this policy get enforced in the SDN architecture?

The application sends the policy to the controller via a northbound API, and the controller translates it into flow entries for the data plane.

The application directly configures each switch via the southbound API.

The application is embedded in the data plane and enforces the policy locally.

The controller sends the policy to the application for validation before enforcement.

In an NFV environment, what role does SDN play?

It offers the storage for VNF images

It manages the lifecycle of VNFs

It enables dynamic and programmable network connectivity between VNFs

It provides the compute resources for running VNFs

A network team is evaluating southbound protocols for a new SDN deployment. They need to support both flow-level forwarding control and device configuration management. They also want to use a single protocol to simplify operations. Which protocol should they choose?

A combination of OpenFlow and NETCONF

SDN Architecture JN0-214 Practice Questions (Page 2)

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.
