dbutils.widget. Just passed the exam with score >80%. examtopics covers about 90% of questions. there were 5 questions I didn't see here in examtopics. But friends, you need to look at the discussions, and do test yourself. many answers provided here, even most voted answer, does NOT exists anymore in the exam - not the question, but the answer. Wish you all good luck, friends!

I'm confused, shall the f-string use curly brackets instead of parenthesys?

widget is correct

Suretly E

E 100% There is no such thing as dbutils.notebooks.getParam, so no idea why some halfwits suggest D...

dbutils.widgets is where we store all the param and use .get to fetch the params

D is correct! The question states that the upstream system passes the date as a parameter to the Databricks Jobs API. In Databricks, when a parameter is passed to a notebook via the Jobs API, it can be retrieved using the dbutils.notebooks.getParam() method. Option D directly retrieves the parameter value using this method, which is the correct approach for this scenario.

It is the way to fill in a parameter in a notebook

Around question #130 they just repeat themselves. So it's not 226 but around 130... Shame

Jobs API allows to sending parameters via jobs parameter. This parameter must have the same notebook params. Eventually, it can be read using dbutils.widgets.get

E is correct because: A - gets configuration of a spark session B - gets a value from a manual input - non relevant for the job run C - sys.argv - gets parameters, which were used to run a Pyrhon script from CMD - completely non-related D - haven't found this function on the web at all, assume that it doesn't exist Therefore E is correct, though it's a bad practice to type a date as a parameter, it's better to get it with datetime library and then use it in the code

Answer is E. Even though the value is passed from a upstream system, you can create parameters using widgets inside notebook and use the value as an input from the databricks jobs API.

Widgets are used to create parameters in notebook that can be then utilized by e.g. jobs

E. E. dbutils.widgets.text("date", "null") date = dbutils.widgets.get("date")

correct ans is E

Are you reading the question? It asks about an upstream system that has been configured to pass the date for a given batch of data to the Databricks Jobs API as a parameter. Upstream system usually don't use widgets. Widgets they are made for humans. Only C and D are correct but D is better so D.

vote for E dbutils.widget
