You have an Azure Synapse Analytics dedicated SQL pool that contains a table named Table1.

You have files that are ingested and loaded into an Azure Data Lake Storage Gen2 container named container1.

You plan to insert data from the files into Table1 and transform the dat

a. Each row of data in the files will produce one row in the serving layer of Table1.

You need to ensure that when the source data files are loaded to container1, the DateTime is stored as an additional column in Table1.

Solution: You use a dedicated SQL pool to create an external table that has an additional DateTime column.

Does this meet the goal?

Show Suggested Answer Hide Answer
Suggested Answer: B

Instead use a serverless SQL pool to create an external table with the extra column.

Note: In dedicated SQL pools you can only use Parquet native external tables. Native external tables are generally available in serverless SQL pools.

No way, I thought external tables couldn't have additional columns like that.

Totally agree, this should work for tracking the DateTime!

Wait, can you really do that with an external table? Sounds a bit off.

I don't think that's enough. You need more than just an external table.

Yes, that makes sense! Extra column for DateTime is a good idea.

I believe the solution could meet the goal, but I wonder if there are any specific requirements for how the DateTime should be formatted when it's loaded into Table1.

I'm a bit confused about whether the external table will actually insert the DateTime into Table1 or just reference it. I feel like I need to review that concept again.

I remember a similar practice question where we had to add metadata to a table, and it involved using external tables too. Maybe this is the right approach?

I think creating an external table with an additional DateTime column might work, but I'm not entirely sure if it captures the DateTime from the source files correctly.

Okay, let's see. If the UE fails to switch, that would likely lead to dropped calls, RRC reestablishment, and other connectivity issues. I think the answer is A, True.

Active Directory sync sounds relevant since many companies use it for user management, but I can't recall if it directly relates to voicemail setup. Could it be D?

I'm leaning towards priority and constraints as the best options. Those attributes would help the BA manage the interdependencies and ensure the most important requirements are delivered first.
