choices:
18-
- content: "Data is stored in a relational database store and can't be directly accessed in the data lake files."
19-
isCorrect: false
20-
explanation: "Incorrect. File storage is decoupled from the relational database schema and query processing."
21-
- content: "Data is stored in files that can't be queried using SQL."
22-
isCorrect: false
23-
explanation: "Incorrect. You can use SQL to query data in a lake database."
24-
- content: "A relational schema is overlaid on the underlying files, and can be queried using a serverless SQL pool or a Spark pool."
25-
isCorrect: true
26-
explanation: "Correct. A lake database abstracts files with a relational schema that can be queried using SQL in a serverless SQL pool or a Spark pool."

- content: "You need to create a new lake database for a retail solution. What's the most efficient way to do this?"
28-
choices:
29-
- content: "Create a sample database in Azure SQL Database and export the SQL scripts to create the schema for the lake database."
30-
isCorrect: false
31-
explanation: "Incorrect. A sample Azure SQL database may not meet your needs, and the scripts wouldn't be suitable for a lake database."
32-
- content: "Start with the Retail database template in Azure Synapse Studio, and adapt it as necessary."
33-
isCorrect: true

explanation: "Correct. The Gallery in Azure Synapse Studio includes industry-proven database schema templates, including one for retail."
35-
- content: "Start with an empty database and create a normalized schema."
36-
isCorrect: false
37-
explanation: "Incorrect. While this approach would work, it's more efficient to start from a template."

39-
choices:

- content: "Use a CREATE EXTERNAL TABLE AS SELECT (CETAS) query to create the table."

43-
- content: "Convert the files in the folder to CSV format."
