Your company has two headquarters, one in London, one in New York. Each of the headquarters
includes several branch offices. The branch offices only need to communicate with the
headquarters in their country, not with each other, and the headquarters need to communicate
directly. What is the BEST configuration for establishing VPN Communities among the branch
offices and their headquarters, and between the two headquarters? VPN Communities comprised
of:
A.
Three star Communities: The first one is between New York headquarters and its branches.
The second star Community is between London headquarters and its branches. The third star
Community is between New York and London headquarters but it is irrelevant which site is
“center” and which “satellite”.
B.
One star Community with the option to mesh the center of the star: New York and London
Gateways added to the center of the star with the “mesh center Gateways” option checked; all
London branch offices defined in one satellite window; but, all New York branch offices defined in
another satellite window.
C.
Two mesh and one star Community: Each mesh Community is set up for each site between
headquarters their branches. The star Community has New York as the center and London as its
satellite.
D.
Three mesh Communities: one for London headquarters and its branches; one for New York
headquarters and its branches; and one for London and New York headquarters.
Explanation:
VPN Communities
A VPN Domain is the internal networks that use Security Gateways to send and receive VPN traffic. Define the resources that are included in the VPN Domain for each Security Gateway. Then join the Security Gateways into a VPN community. Network resources of the different Security Gateways can securely communicate with each other through VPN tunnels.
VPN communities are based on Star and Mesh topologies. In a Mesh community, there are VPN connections between each Security Gateway. In a Star community, satellites have a VPN connection with the center Security Gateway, but not to each other.
