Networking and Software-Defined Networks (SDN) Quiz

SDN stands for Software-Defined Network, a network architecture that allows centralized control and programmability of network resources.

One of the key advantages of SDN is centralized network management, providing a unified control point for network resources.

The role of the SDN controller is to provide a centralized control point for managing and directing network traffic.

The primary function of the Data Plane in SDN is to forward packets based on instructions from the centralized controller.

One of the main advantages of SDN over traditional networking is enhanced network programmability.

SDN is primarily associated with the Network Layer of the OSI model.

OpenFlow is commonly used in SDN for communication between the controller and switches.

The primary goal of SDN is to centralize network management, improving efficiency and flexibility.

Python is commonly used to write SDN controller applications due to its simplicity and versatility.

SDN is characterized by reduced hardware dependency, as it emphasizes software-based control.

A key principle of SDN architecture is centralized control, enabling efficient network management.

A potential challenge of implementing SDN is decreased network visibility, which can impact monitoring and troubleshooting.

The Application Plane is not a component of SDN architecture.

The Southbound API in SDN is designed to facilitate communication between the controller and switches.

SDN controllers do not perform packet forwarding; they focus on centralized control and management.

NETCONF is typically used for communication between SDN controllers in a distributed SDN environment.

A limitation of SDN is limited support for legacy hardware, requiring infrastructure upgrades for full compatibility.
