For which of the following reasons could a single server’s NIC transmit packets from multiple MAC
address sources?
A.
The server contains several virtual machines and the MAC addresses are from the virtual
machines.
B.
The server is hosting a web server and the MAC addresses are from connected browsers.
C.
The server is hosting a proxy server and the MAC addresses are from the connected clients.
D.
The server NIC is starting to fail and should be replaced.
How the f*** should I know that they are in a virtual environment?
Use deductive reasoning. B, C, and D wouldn’t cause a NIC to send out multiple MAC addresses thus the only possible answer is A meaning they have a virtual environment.
Thank You
If you try installing VMWARE Workstation on your machine and then install a couple virtual machines, you’ll see that you will also have 1 or more virtual NICS installed on your physical machine. These NICS get assigned DHCP info/MAC addresses just like the NIC that came with your machine.
