a database scoped credentialan asymmetric keyan external data sourcea database encryption keyan external file format

Correct arrangement

  • a database scoped credential
  • an external data source
  • an external file format

Explanation

To configure PolyBase to connect Azure Synapse Analytics to an Azure Data Lake Storage Gen2 account, you must first create a database scoped credential to securely store the storage account credentials (application ID and access key or managed identity). Next, you create an external data source that references the credential and points to the ADLS Gen2 location. Finally, you create an external file format to define the structure and format (e.g., Parquet, CSV, ORC) of the files to be loaded - this sequence is mandatory as each object depends on the prior one.
