What is a key advantage of using a virtual switch over a traditional switch?

Using a virtual switch offers the significant advantage of reduced physical space requirements. In a virtualized environment, multiple virtual switches can operate on the same physical hardware, enabling numerous virtual machines to communicate without the need for additional physical switches. This reduction in hardware not only minimizes the space needed for networking devices but also simplifies the infrastructure. By virtualizing the networking layer, organizations can achieve better resource utilization and flexibility in managing their network without the overhead of physical equipment.

Higher speed data transfer and enhanced security protocols are not inherent advantages of virtual switches specifically but can depend on the configuration and underlying physical hardware. Increased power consumption typically would not be an advantage of virtual switches, as they generally lead to a decrease in physical devices that consume power. Therefore, the choice highlighting the reduced physical space requirements accurately reflects a key benefit of implementing virtual switches in a network environment.
