When deploying an SDN controller in a cloud environment, why is high availability (HA) an important consideration?

To provide redundancy so that network control is not lost if the controller fails

To reduce the latency between the controller and network devices

To allow the controller to be accessed from anywhere

To ensure the controller can handle a large number of network devices

In a software-defined networking (SDN) architecture, what is the primary role of the SDN controller?

To encrypt all network traffic to ensure secure communication between hosts

To forward data packets between network devices based on MAC addresses

To physically connect network devices and provide high-speed data transmission

To provide a centralized control plane that manages network devices through a standardized interface

In an SDN architecture, what is the purpose of the southbound interface?

To enable communication between multiple SDN controllers

To connect the SDN controller to the internet for cloud services

To provide an API for applications to request network services

To allow communication between the SDN controller and the network devices it controls

A cloud service provider is deploying an SDN controller to manage a multi-tenant environment. The controller must support a large number of virtual networks and tenants, and it must remain available during maintenance windows. The team is considering a clustered deployment. Which consideration is most important when deciding between active-active and active-standby clustering?

Active-active is simpler to configure than active-standby

Active-standby provides better performance because only one controller is active

Active-standby is required for multi-tenant environments

Active-active provides better scalability by distributing the load across controllers

Which of the following is a core function performed by an SDN controller?

Performing packet forwarding at line rate

Providing DHCP services to end hosts

Terminating VPN tunnels for remote users

Discovering the network topology

SDN Controller JN0-214 Practice Questions (Page 3)

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.
