Actual exam question from Microsoft's DP-203
Question #: 19
Topic #: 4
[All DP-203 Questions]

You configure monitoring for an Azure Synapse Analytics implementation. The implementation uses PolyBase to load data from comma-separated value (CSV) files stored in Azure Data Lake Storage Gen2 using an external table.
Files with an invalid schema cause errors to occur.
You need to monitor for an invalid schema error.
For which error should you monitor?

  • A. EXTERNAL TABLE access failed due to internal error: 'Java exception raised on call to HdfsBridge_Connect: Error [com.microsoft.polybase.client.KerberosSecureLogin] occurred while accessing external file.'
  • B. Cannot execute the query "Remote Query" against OLE DB provider "SQLNCLI11" for linked server "(null)". Query aborted- the maximum reject threshold (0 rows) was reached while reading from an external source: 1 rows rejected out of total 1 rows processed.
  • C. EXTERNAL TABLE access failed due to internal error: 'Java exception raised on call to HdfsBridge_Connect: Error [Unable to instantiate LoginClass] occurred while accessing external file.'
  • D. EXTERNAL TABLE access failed due to internal error: 'Java exception raised on call to HdfsBridge_Connect: Error [No FileSystem for scheme: wasbs] occurred while accessing external file.'

Selected Answer: B
To monitor for an invalid schema error when using PolyBase to load data from CSV files in Azure Data Lake Storage Gen2 using an external table in Azure Synapse Analytics, you should monitor the following error: B. Cannot execute the query "Remote Query" against OLE DB provider "SQLNCLI11" for linked server "(null)". Query aborted- the maximum reject threshold (0 rows) was reached while reading from an external source: 1 rows rejected out of total 1 rows processed. This error indicates that a row in the CSV file has been rejected due to an invalid schema. By monitoring for this error, you can identify when data loading fails due to an incompatible or incorrect schema in the CSV files.
