DP-300 Implement a secure environment Practice Question

Exhibit

SET IDENTITY_INSERT dbo.Orders ON;
INSERT INTO dbo.Orders (OrderID, CustomerName) VALUES (1001, 'Contoso');
SET IDENTITY_INSERT dbo.Orders OFF;

Refer to the exhibit. You are reviewing a script that is executed as part of a data migration to Azure SQL Database. The script attempts to insert a row with a specific OrderID into an Orders table that has an identity column. The script runs successfully in a test environment but fails in production with an error. The production environment has the same schema. What is the most likely cause?

⚠ Common exam trap

It's easy for candidates to assume INSERT permission is sufficient for inserting into an identity column, overlooking that SET IDENTITY_INSERT ON is a schema-modifying operation requiring ALTER permission.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

The user running the script does not have ALTER permission on the table

The script uses SET IDENTITY_INSERT ON to allow explicit insertion into an identity column. In Azure SQL Database, this requires ALTER permission on the table, not just INSERT. The test environment likely granted the user ALTER, but production did not, causing the failure despite identical schema.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • ✓

    The user running the script does not have ALTER permission on the table

    Why this is correct

    SET IDENTITY_INSERT requires ALTER permission on the table.

  • ✗

    The table in production does not have an identity column

    Why it's wrong here

    The schema is the same.

  • ✗

    A different session is already using SET IDENTITY_INSERT ON for the same table

    Why it's wrong here

    This would cause a different error, but the script runs in test successfully, so unlikely.

  • ✗

    The identity column in production has a different seed value

    Why it's wrong here

    Identity seed does not affect IDENTITY_INSERT.
