A programming team is deploying a new PHP module to be run on a Solaris 10 server with trusted extensions. The server is configured with three zones, a management zone, a customer zone, and a backend zone. The security model is constructed so that only programs in the management zone can communicate data between the zones. After installation of the new PHP module, which handles on-line customer payments, it is not functioning correctly.
Which of the following is the MOST likely cause of this problem?
A . The PHP module is written to transfer data from the customer zone to the management zone, and then from the management zone to the backend zone.
B . The iptables configuration is not configured correctly to permit zone to zone communications between the customer and backend zones.
C . The PHP module was installed in the management zone, but is trying to call a routine in the customer zone to transfer data directly to a MySQL database in the backend zone.
D . The ipfilters configuration is configured to disallow loopback traffic between the physical NICs associated with each zone.
