An advantage of using central instead of local licensing is:
A.
A license can be taken from one Security Management server and given to another Security Management Server.
B.
Only one IP address is used for all licenses.
C.
Licenses are automatically attached to their respective Security Gateways.
D.
The license must be renewed when changing the IP address of security Gateway. Each module’s license has a unique IP address.
I have the same idea. B
