SDN: Understanding Software-Defined Networking

What does SDN stand for and why is it important in cloud environments?

• Software Data Negotiation, because it helps in data bargaining

• Secure Digital Networks, because it enhances security

• Systematic Data Networking, because it organizes data more efficiently

• Software-Defined Networking, because it replaces physical devices with software versions

What is the primary function of the Data Plane in SDN?

• To provide a user interface for network management

• To manage device configurations

• To forward network traffic based on protocols

• To encrypt and secure data transmissions

Which layer of SDN is responsible for dynamic routing protocols?

• Infrastructure Layer

• Control Layer

• Application Layer

• Management Layer

What is the role of the Data Plane in SDN?

• To forward network traffic

• To interface with end-users

• To manage network configurations

• To encrypt data transmissions

Which layer of SDN is directly involved in the forwarding of network packets?

• Control Plane

• Security Plane

• Data Plane

• Management Plane

What does the Control Plane primarily manage in SDN?

• Traffic forwarding and routing tables

• User access and security

• Physical device maintenance

• Software updates and patches

How does the Control Plane in SDN determine the routing of traffic?

• By external network services

• By software algorithms

• By manual configuration

• By physical switches

Through which interfaces can a network device be managed in the Management Plane?

• API and SSH

• HTTP and FTP

• UDP and TCP

• SMTP and SNMP

Which protocol is commonly used to access the Management Plane?

• Secure Shell (SSH)

• Hypertext Transfer Protocol (HTTP)

• Transmission Control Protocol (TCP)

• Simple Mail Transfer Protocol (SMTP)

Which layer of SDN would you interact with when using a graphical interface of a firewall?

• Management Plane

• Data Plane

• Security Plane

• Control Plane
