VXRAIL exam Simulation - internal or external Vcenter & DNS!?

Hello Community,

Can anyone guide me to the exact way to check on the exam simulator if the DNS used is internal or external?

for Vcenter usually it's just about looking for embedded Vcenter VM (internal) or not (External).

But for the DNS, since there are very limited tabs to navigate through and we have no option to launch the web console in order to use the NSLOOKUP command for example, anyone knows a simple way to detect Internal/external DNS within the constraints of the DES-6322 simulator ?
