Answer: They can set up an Alert with a new webhook alert destination.
## Explanation The correct answer is **C** because: 1. **Webhook Alert Destination**: Databricks SQL Alerts support webhook destinations that can send notifications to messaging platforms like Slack, Microsoft Teams, or other custom webhook endpoints. 2. **Alert Configuration**: The data engineer can: - Create an Alert on the Databricks SQL query that monitors NULL values - Set the alert condition to trigger when the query result reaches 100 - Configure a webhook alert destination pointing to their team's messaging platform 3. **Why other options are incorrect**: - **A (custom template)**: Custom templates only change the format of notifications but don't determine the delivery method - **B (email alert destination)**: This would send email notifications, not webhook notifications - **D (one-time notifications)**: This refers to notification frequency, not the delivery method - **E (without notifications)**: This would not send any notifications at all 4. **Implementation Steps**: ```sql -- Query example that returns count of NULL values SELECT COUNT(*) as null_count FROM input_data WHERE column_name IS NULL; ``` - Create Alert on this query - Set condition: `null_count >= 100` - Add webhook destination with team's messaging webhook URL - Configure alert to run on a schedule (e.g., every 5 minutes) This approach ensures the team receives real-time notifications in their messaging platform when data quality issues reach the threshold.
