What should you create first?

You have an Azure Synapse Analytics serverless SQL pool named Pool1 and an Azure Data Lake Storage Gen2 account named storage1. The AllowedBlobpublicAccess porperty is disabled for storage1.

You need to create an external data source that can be used by Azure Active Directory (Azure AD) users to access storage1 from Pool1.

What should you create first?
A . an external resource pool
B. a remote service binding
C. database scoped credentials
D. an external library

Answer: C

Explanation:

Security

User must have SELECT permission on an external table to read the data. External tables access underlying Azure storage using the database scoped credential defined in data source.

Note: A database scoped credential is a record that contains the authentication information that is required to connect to a resource outside SQL Server. Most credentials include a Windows user and password.
