Which term describes a network address used by a virtual machine to communicate on a physical network?

• A. Provider Address
• B. Public IP Address
• C. Private IP Address
• D. Loopback Address

Answer: (A)

When a virtual machine needs to talk to devices on the actual physical network, it uses an address that the physical network can route to. This address, assigned on the path that connects the VM to the real network, is called the provider address. It represents how the VM appears on the external network and is the IP that other devices on the physical network use to reach the VM.

In contrast, a private IP address is used inside the virtual network and isn’t directly reachable from the outside world. A public IP address is the address seen on the broader Internet, which might be mapped to a private address through NAT or other mechanisms. A loopback address (like 127.0.0.1) is used only to communicate with the same host and isn’t used to reach other devices on the network.

So the term that best fits a network address used by a virtual machine to communicate on the physical network is the provider address.
