Which statement characterizes the general programming model used by Spark Structured Streaming?

• A.Structured Streaming leverages the parallel processing of GPUs to achieve highly parallel data throughput.
• B.Structured Streaming is implemented as a messaging bus and is derived from Apache Kafka.
• C.Structured Streaming uses specialized hardware and I/O streams to achieve sub-second latency for data transfer.
• D.Structured Streaming models new data arriving in a data stream as new rows appended to an unbounded table.
• E.Structured Streaming relies on a distributed network of nodes that hold incremental state values for cached stages.

The data engineering team has configured a Databricks SQL query and alert to monitor the values in a Delta Lake table. Therecent_sensor_recordingstable contains an identifyingsensor_idalongside thetimestampandtemperaturefor the most recent 5 minutes of recordings.
The below query is used to create the alert:

The query is set to refresh each minute and always completes in less than 10 seconds. The alert is set to trigger whenmean (temperature) > 120. Notifications are triggered to be sent at most every 1 minute.
If this alert raises notifications for 3 consecutive minutes and then stops, which statement must be true?

• A.The total average temperature across all sensors exceeded 120 on three consecutive executions of the query
• B.Therecent_sensor_recordingstable was unresponsive for three consecutive runs of the query
• C.The source query failed to update properly for three consecutive minutes and then restarted
• D.The maximum temperature recording for at least one sensor exceeded 120 on three consecutive executions of the query
• E.The average temperature recordings for at least one sensor exceeded 120 on three consecutive executions of the query

If this statement is executed by a workspace admin, which result will occur?

• A.Nothing will occur until a COMMIT command is executed.
• B.The table will be removed from the catalog but the data will remain in storage.
• C.The table will be removed from the catalog and the data will be deleted.
• D.An error will occur because Delta Lake prevents the deletion of production data.
• E.Data will be marked as deleted but still recoverable with Time Travel.
