   A BIG-IP DNS sync group has been working correctly for months. After a network change, the administrator notices that configuration changes on the primary system are no longer propagating to the secondary system. The administrator has verified that the secondary system is still a member of the sync group. What is the most likely cause of this issue?

   • AThe iQuery port is blocked by a firewall between the two systems.
   • BThe secondary system has a different software version.
   • CThe secondary system's DNS service is not running.
   • DThe primary system's NTP settings are incorrect.

   • AThe system's network interface is faulty.
   • BThe system's software version is different from the other members.
   • CThe system's DNS cache is full.
   • DThe system's clock is not synchronized with the other members, causing authentication failures.
