A user accidentally deletes an enterprise geodatabase feature dataset.
Which technology should be used to resolve the issue?
Understanding the Scenario:
An enterprise geodatabase feature dataset is accidentally deleted.
The organization needs to recover the dataset to its original state.
Available Technologies:
High Availability: High availability setups (e.g., failover systems) ensure continuous access to geodatabases during hardware or software failures. However, high availability does not restore accidentally deleted data.
Backup: A backup is a snapshot of the geodatabase taken at a specific point in time. It allows administrators to restore deleted datasets or recover from data loss scenarios.
Archiving: Archiving tracks historical edits in versioned geodatabases but does not provide recovery for accidentally deleted datasets.
Steps to Recover the Dataset:
Identify the most recent backup of the enterprise geodatabase.
Restore the geodatabase or extract the specific feature dataset from the backup.
Verify the restored data and synchronize it with ongoing updates if necessary.

Why the Correct Answer is B: A backup is the most reliable solution for recovering an accidentally deleted feature dataset. High availability ensures uptime but does not address data recovery, and archiving tracks edits rather than preserving entire datasets.
