An engineering manager uses a Databricks SQL query to monitor ingestion latency for each data source. The manager checks the results of the query every day, but they are manually rerunning the query each day and waiting for the results.
Which of the following approaches can the manager use to ensure the results of the query are updated each day?

• A.They can schedule the query to refresh every 1 day from the SQL endpoint's page in Databricks SQL.
• B.They can schedule the query to refresh every 12 hours from the SQL endpoint's page in Databricks SQL.
• C.They can schedule the query to refresh every 1 day from the query's page in Databricks SQL.
• D.They can schedule the query to run every 1 day from the Jobs UI.
• E.They can schedule the query to run every 12 hours from the Jobs UI.

A data engineer has developed a Python notebook in a Databricks workspace and configured it to run as a scheduled job to process daily sales data.
How are the storage and execution of this notebook managed within the Databricks architecture?

• A.The notebook is stored securely and encrypted in the compute plane, and the code executes in the control plane when the job runs.
• B.The notebook is stored unencrypted in the workspace storage bucket, and the code executes on the cluster driver node in the compute plane when the job runs.
• C.The notebook is stored securely and encrypted in Unity Catalog, and the code executes in Delta Lake when the job runs.
• D.The notebook is stored securely and encrypted in the control plane, and the code executes in the compute plane when the job runs.

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.
Assuming previously unprocessed data exists and all definitions are valid, what is the expected outcome after clicking Start to update the pipeline?

• 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 persist without any processing. The compute resources will persist but go unused.
• 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.
• E.All datasets will be updated once and the pipeline will shut down. The compute resources will persist to allow for additional testing.
