What are vSwitches used for?

• A. To Ensure connections between virtual machines as well as connecting virtual and physical networks
• B. To Manage Power Usage
• C. To Create Backup Copies
• D. To Monitor CPU Usage

Answer: (A)

A vSwitch provides network switching inside the virtualization layer. It connects virtual machines to each other on the same host and bridges their traffic to the physical network through physical NICs. Each VM uses a virtual NIC that attaches to a port group on the vSwitch, so traffic can stay within the virtual environment or travel out to the physical network as needed. This enables VM-to-VM communication and connectivity to external networks while allowing network segmentation and policy control through port groups and VLANs.

Power usage, backups, and CPU monitoring are handled by other tools and features, not by the vSwitch.
