101 Question #707: Real Exam Question with Answer & Explanation
The correct answer is A: synchronize the settings of device 1 to the group. In a BIG-IP Device Service Clustering (DSC) group, after changing configuration on one device the administrator must sync that device's config outward to the group so all peers receive the update.
Question
A BIG-IP Administrator has a cluster of devices. What should the administrator do after creating a new Virtual Server on device 1?
Options
- Asynchronize the settings of device 1 to the group
- Bcreate a new cluster on device 1
- Ccreate the new virtual server on device 2
- Dsynchronize the settings of the group to device 1
Explanation
In a BIG-IP Device Service Clustering (DSC) group, after changing configuration on one device the administrator must sync that device's config outward to the group so all peers receive the update.
Common mistakes.
- B. Creating a new cluster is unnecessary because a sync group already exists; DSC replicates changes through synchronization, not by forming additional clusters.
- C. Manually creating the Virtual Server on device 2 is redundant and error-prone; DSC synchronization is the correct and authoritative mechanism for propagating configuration changes.
- D. Syncing from the group to device 1 would overwrite device 1's current configuration with the group's older state, deleting the newly created Virtual Server.
