What does a Distributed Switch allow in a vSphere environment?

A Distributed Switch in a vSphere environment significantly enhances the management and capabilities of networking within a virtualization infrastructure. It allows for advanced networking features and provides centralized management of virtual networking components across multiple hosts. This means that administrators can configure network policies, monitor traffic, and apply settings consistently across all virtual machines connected to the Distributed Switch, regardless of the physical host they reside on.

One of the key benefits of utilizing a Distributed Switch is its ability to facilitate advanced technologies such as traffic shaping, port mirroring, and support for features like Private VLANs (PVLANs). It streamlines the networking configuration process, reducing the complexity associated with managing multiple Virtual Standard Switches, which would require repetitive configurations on each host individually.

The other options, such as basic network configurations and physical server management, do not accurately reflect the comprehensive capabilities that a Distributed Switch offers. Additionally, virtual storage management does not fall under the purview of networking but relates to how virtual machines access storage resources, further highlighting why centralized management and advanced features in networking are the correct focus for a Distributed Switch.
