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 an Azure Synapse Analytics serverless 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: A

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

Sounds good to me, but I’d double-check the syntax.

Wait, can you really do that with a serverless SQL pool?

I disagree, it won't automatically add DateTime to Table1.

Yes, that works! External tables can have extra columns.

I’m a bit confused; I thought external tables were mainly for querying data without loading it into the dedicated pool. Does that mean it won't meet the goal?

I'm leaning towards "No" because I believe the DateTime needs to be part of the actual table structure, not just an external reference.

I think creating an external table with an additional DateTime column could work, but I'm not entirely sure if it meets the requirement for Table1.

I remember a similar practice question where we had to add metadata to a table. I feel like this might be a bit different since we’re dealing with an external table.

Okay, I think I've got it. The key is to focus on how the organization's resources, which include things like materials, equipment, and personnel, are used to create the products and services.

No problem, I've got this. The space loss is proportional to the square of the frequency, so the 15 GHz link will have significantly higher space loss than the 7 GHz link. I just need to plug in the numbers and find the difference.

This one seems pretty straightforward. I'm pretty confident the answer is C - Smoke detector.
