What is the primary objective of Network Virtualization?

  1. To improve network security

  2. To enhance network performance

  3. To reduce network complexity

  4. To enable network resource sharing


Correct Option: D
Explanation:

Network Virtualization aims to divide a physical network into multiple virtual networks, allowing multiple users or applications to share the same physical infrastructure.

Which technology is commonly used to create virtual networks?

  1. VLANs

  2. MPLS

  3. VXLAN

  4. GRE


Correct Option: C
Explanation:

VXLAN (Virtual Extensible LAN) is a widely adopted technology for creating virtual networks over a shared physical infrastructure.

What is the primary benefit of using Software-Defined Networking (SDN) in Network Virtualization?

  1. Increased network flexibility

  2. Enhanced network security

  3. Improved network performance

  4. Reduced network costs


Correct Option: A
Explanation:

SDN decouples the control plane from the data plane, enabling greater flexibility in network configuration and management.

Which protocol is commonly used for communication between SDN controllers and network devices?

  1. HTTP

  2. TCP

  3. OpenFlow

  4. BGP


Correct Option: C
Explanation:

OpenFlow is a widely used protocol for communication between SDN controllers and network devices, enabling the controller to program the forwarding behavior of the devices.

What is the primary advantage of using Network Function Virtualization (NFV) in Network Virtualization?

  1. Reduced network complexity
