[All Databricks Certified Data Engineer Associate Questions]

A data engineer wants to schedule their Databricks SQL dashboard to refresh every hour, but they only want the associated SQL endpoint to be running when it is necessary. The dashboard has multiple queries on multiple datasets associated with it. The data that feeds the dashboard is automatically processed using a Databricks Job.

Which of the following approaches can the data engineer use to minimize the total running time of the SQL endpoint used in the refresh schedule of their dashboard?

AThey can turn on the Auto Stop feature for the SQL endpoint.

BThey can ensure the dashboard's SQL endpoint is not one of the included query's SQL endpoint.

CThey can reduce the cluster size of the SQL endpoint.

DThey can ensure the dashboard's SQL endpoint matches each of the queries' SQL endpoints.

EThey can set up the dashboard's SQL endpoint to be serverless.

I disagree, matching SQL endpoints seems unnecessary.

Not sure about that, isn't it risky to change the cluster size?

I think reducing the cluster size could help too.

Auto Stop is a game changer for saving costs!

Setting up a serverless SQL endpoint sounds familiar, and I think it could help with efficiency, but I need to double-check how it relates to the refresh schedule.

I feel like ensuring the SQL endpoints match is important for performance, but I can't recall if it helps with minimizing running time specifically.

I think I practiced a question similar to this where reducing the cluster size was mentioned, but I'm not confident if that applies here.

I remember something about the Auto Stop feature being useful for saving costs, but I'm not entirely sure if it directly minimizes running time.

Okay, I think I've got this. The key is that the question says you would choose between the two, but not use both together. So the correct answer must be True - you wouldn't use an enterprise service bus and an orchestration product simultaneously in the same architecture.

Hmm, this looks like a tricky one. I'll need to think carefully about the different configuration files and how they relate to repository performance.

Okay, I've reviewed the question and the options. I believe the correct answer is Option C, since the cumulative effect of an inventory pricing change would be reported as an adjustment to retained earnings, not on the current year's income statement.

I thought 'Ctx' was for context, but I can't recall if it can be used interchangeably with 'Vrf'. Maybe option D is correct after all?

Option D seems like it would just add more complexity. I agree with the others - go with the serverless option (Option E) for a simple and effective solution.

Haha, I bet the data engineer is wishing they had a magic wand to make this all work perfectly. Serverless SQL (Option E) seems like the most effortless way to go.

Hmm, I'm not sure if reducing the cluster size (Option C) is the best idea. That might impact performance. I think the serverless approach (Option E) is the cleanest solution here.
