[All Databricks Certified Data Analyst Associate Questions]

Which of the following approaches can be used to ingest data directly from cloud-based object storage?

Show Suggested Answer Hide Answer
Suggested Answer: A

Option A uses theSELECT DISTINCTstatement to remove duplicate rows from thetable_bronzeand create a new tabletable_silverwith the deduplicated data.This is the correct way to deduplicate data using Spark SQL12. Option B simply inserts all the rows fromtable_bronzeintotable_silver, without removing any duplicates. Option C is not a valid syntax for Spark SQL, as there is noMERGE DEDUPLICATEstatement. Option D appends all the rows fromtable_bronzeintotable_silver, without removing any duplicates. Option E overwrites the existing data intable_silverwith the data fromtable_bronze, without removing any duplicates.Reference:Delete Duplicate using SPARK SQL,Spark SQL - How to Remove Duplicate Rows

I vaguely recall that DBFS is related to Databricks, but I can't remember if it should be used with FROM or PATH.

I feel like option C is definitely wrong; we can ingest data from cloud storage, right?

The key here is understanding how external tables work. Option E seems to provide the most direct way to access the data in cloud storage.

Option C seems a bit too extreme. I'm confident that we can directly ingest data from cloud storage, we just need to use the right approach.

Hmm, I'm a bit confused. Are options A and D also valid approaches? I'll need to double-check the documentation to be sure.

This looks straightforward. I think option E is the way to go - creating an external table and specifying the object storage path in the LOCATION clause.

I think the key is to focus on the factors that directly impact the system's capacity and performance. The other options seem more peripheral.

I'm going with option E. 'Create an external table while specifying the object storage path to LOCATION.' You know, because LOCATION is where the party's at.

Haha, option C is a classic. 'It's not possible to directly ingest data from cloud-based object storage'? Yeah, right. Clearly the person who wrote that option has never heard of external tables.

I was going to choose option B, but then I remembered that DBFS is for Databricks File System, not object storage. Gotta pay attention to the details!

Option D is correct. The question asks how to ingest data directly from cloud-based object storage, and the correct answer is to create an external table while specifying the object storage path to the LOCATION clause.
