A large enterprise is considering SDN to automate network provisioning in its private cloud. The network team is concerned about the operational risk of a single point of failure in the control plane. They also need to support legacy devices that do not support OpenFlow. Which approach best addresses these concerns while still gaining SDN benefits?

Deploy SDN only in the data center and keep the WAN unchanged

Use a single controller and replace all legacy devices with OpenFlow-capable switches

Deploy a highly available SDN controller cluster and use protocol translation or hybrid mode for legacy devices

Use a distributed routing protocol instead of SDN

An SDN deployment uses a single controller. The network team is concerned about the risk of a controller failure causing a widespread outage. They are considering deploying a cluster of controllers. What is the primary benefit of a controller cluster in this scenario?

It provides high availability and failover, reducing the risk of a single point of failure

It simplifies the management plane

It eliminates the need for OpenFlow

It increases the data plane forwarding capacity

A cloud provider is evaluating SDN to improve network agility. The operations team is concerned about the learning curve for network engineers who are used to CLI-based configuration. The security team wants to ensure that the SDN controller itself is not a target for attacks. Which combination of actions best addresses both concerns?

Provide training on SDN concepts and APIs, and secure the controller with strong authentication and encrypted communication

Deploy SDN only in the core network and leave the access layer unchanged

Use a single controller with default settings to simplify management

Keep the existing CLI for all devices and do not deploy SDN

A cloud provider is considering SDN to reduce operational costs. The provider has a large number of switches that are currently configured manually. The provider also has a team of network engineers who are experienced with CLI but not with programming. Which approach would best help the provider achieve cost savings while minimizing the learning curve?

Deploy SDN with a controller that provides a GUI-based interface for network provisioning, and provide training on SDN concepts

Deploy SDN but do not provide any training

Require all engineers to learn Python and use APIs exclusively

Keep manual CLI configuration and do not deploy SDN

SDN Solutions JN0-214 Practice Questions (Page 4)

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 29 practice questions to prepare you well beyond it.
