Exam F5CAB2 Topic 4 Question 51 Discussion

Comprehensive and Detailed Explanation (BIG-IP Administration - Data Plane Concepts):
In a BIG-IP device service cluster, configuration objects such as virtual servers, pools, profiles, and iRules are maintained through configuration synchronization (config-sync).
Key BIG-IP concepts involved:
Device Service Cluster (DSC)
A cluster is a group of BIG-IP devices that share configuration data. One device is typically used to make changes, which are then synchronized to the rest of the group.
Config-Sync Direction Matters
Changes are made on a local device
Those changes must be pushed to the group
The correct operation is "Sync Device to Group"
Why C is correct:
The virtual server was created only on device 1
Other devices in the cluster do not yet have this object
To propagate the new virtual server to all cluster members, the administrator must synchronize device 1 to the group Why the other options are incorrect:
A . Synchronize the settings of the group to device 1
This would overwrite device 1's configuration with the group's existing configuration and may remove the newly created virtual server.
B . Create a new cluster on device 1
The cluster already exists. Creating a new cluster is unnecessary and disruptive.
D . Create a new virtual server on device 2
This defeats the purpose of centralized configuration management and risks configuration drift.
Conclusion:
After creating a new virtual server on a BIG-IP device that is part of a cluster, the administrator must synchronize the configuration from that device to the group so all devices share the same ADC application objects.
