An administrator has configured a Linux virtual machine and found
that it does not have network connectivity. The administrator notices this
when trying to ping the default gate way and nothing comes back. The

A.

Ping an outside source to see if you get a response


B.

Verify that VMware Tools has been loaded on the guest operating system
