   Which statement best describes how a software update can affect the configuration state of a BIG-IP DNS group?

   • AUpdates can temporarily interrupt configuration synchronization, but the group typically resyncs after the update completes.
   • BUpdates automatically apply new configuration templates to all devices in the group.
   • CUpdates have no impact on configuration state because configuration is stored externally.
   • DUpdates always cause a permanent loss of configuration synchronization across the group.

   A BIG-IP DNS group has a configuration that includes a data center and a server object. After a software update on one device, the admin notices that the data center is missing from the configuration on that device. What is the most likely cause?

   • AThe configuration sync failed after the update, so the device has a stale configuration.
   • BThe software update deleted the data center object.
   • CThe data center was never configured on that device.
   • DThe software update changed the data center's name.

   An admin is upgrading a BIG-IP DNS sync-failover group. The group has a custom iRule that is used for DNS load balancing. After upgrading the active device, the admin notices that the iRule is no longer being applied to the virtual server, and the configuration on the standby device still has the iRule. What is the most likely cause?

   • AThe active device's config sync was set to 'manual', so the iRule was not propagated after the upgrade.
   • BThe upgrade process reset the active device's configuration to defaults, removing the iRule.
   • CThe iRule was not included in the config sync, so it was lost on the active device.
   • DThe iRule is incompatible with the new TMOS version and was automatically disabled during the upgrade.

   An administrator wants to minimize disruption to monitoring and configuration state during a BIG-IP DNS group software update. Which mitigation strategy is most appropriate?

   • APerform a rolling update, updating one device at a time while keeping the rest of the group operational.
   • BSkip the update to avoid any impact.
   • CDisable configuration synchronization permanently before the update.
   • DUpdate all devices simultaneously to complete the process faster.

   An admin upgrades one BIG-IP DNS device in a sync-failover group from v15 to v16. After the upgrade, the admin notices that the upgraded device is not receiving configuration changes made on the other (still v15) device. The config sync status shows 'pending changes' on the v15 device. What is the most likely cause?

   • AThe v16 device is running a different TMOS version, and config sync is blocked due to version mismatch.
   • BThe v16 device has a different management IP address after the upgrade.
   • CThe v16 device's config sync is paused because the group is in a 'standby' state.
   • DThe v16 device's DNS service is not running, so it ignores config updates.
