What is the main benefit of network virtualization?

The primary advantage of network virtualization lies in its ability to manage the network as a single administrative entity. This means that rather than dealing with individual physical devices and the complexities associated with managing them separately, network virtualization allows administrators to view and control network resources as a unified whole.

By abstracting the underlying hardware and creating a virtual network environment, organizations can allocate resources more efficiently, streamline management tasks, and enhance security measures. This centralized management simplifies network operations, making it easier to deploy changes, manage configurations, and maintain oversight across the entire network infrastructure.

In contrast, the other options suggest negative outcomes or misinterpretations of network virtualization. For instance, decreasing data transfer rates, eliminating monitoring needs, and complicating configurations do not accurately reflect the intended benefits or functionalities of network virtualization. Instead, it aims to optimize and simplify administration while maintaining or enhancing performance and monitoring capabilities.
