On which controller should the license be installed?

A. Only the master controller since role and firewall policies are created here.
B. only the local controllers since firewall policies are applied here
C. the master and all three local controllers
D. this isn't the correct license for this purpose, use PEF-VPN license
E. this is not needed because PEF-NG is part of base OS
