Question DECn5urw7a7L6fAegpBb

Question

A Delta Live Table pipeline includes two datasets defined using STREAMING LIVE TABLE. Three datasets are defined against Delta Lake table sources using LIVE TABLE.

The table is configured to run in Production mode using the Continuous Pipeline Mode.

What is the expected outcome after clicking Start to update the pipeline assuming previously unprocessed data exists and all definitions are valid?

Choices

  • A: All datasets will be updated at set intervals until the pipeline is shut down. The compute resources will persist to allow for additional testing.
  • B: All datasets will be updated once and the pipeline will shut down. The compute resources will persist to allow for additional testing.
  • C: All datasets will be updated at set intervals until the pipeline is shut down. The compute resources will be deployed for the update and terminated when the pipeline is stopped.
  • D: All datasets will be updated once and the pipeline will shut down. The compute resources will be terminated.

Question SVViXkByhOZNTqBjXUS2

Question

A data engineer has developed a data pipeline to ingest data from a JSON source using Auto Loader, but the engineer has not provided any type inference or schema hints in their pipeline. Upon reviewing the data, the data engineer has noticed that all of the columns in the target table are of the string type despite some of the fields only including float or boolean values.

Why has Auto Loader inferred all of the columns to be of the string type?

Choices

  • A: Auto Loader cannot infer the schema of ingested data
  • B: JSON data is a text-based format
  • C: Auto Loader only works with string data
  • D: All of the fields had at least one null value
