Your manager requires you to setup a new corporate VPN between all your branch offices. He requires you to choose the strongest and most secure available algorithms for the headquarters to the Research and Development branch office. In addition, you must use high performance algorithms for all sales offices with shorter key length for the VPN keys. How would you configure this scenario?
A.
This can not be achieved at all as all algorithms need to be the very same for all VPNs.
B.
This can only be done in traditional mode VPNs while not using simplified VPN settings.
C.
This can be done either in traditional mode or simplified VPN using 2 different communities and the headquarters as the center for both communities.
D.
This can be done in a single community, but the encrypt action in the security Rule Base needs to be configured for exceptions.
