Microsoft Administering Relational Databases on Microsoft Azure (DP-300 Deutsch Version) Sample Questions:
Sie planen, mit Azure Databricks ein Dataset namens „Käufe“ zu entwickeln. „Käufe“ soll die folgenden Spalten enthalten:
* Produkt-ID
* Artikelpreis
* Zeilensumme
* Menge
* StoreID
* Minute
* Monat
* Stunde
* Jahr
* Tag
Sie müssen die Daten speichern, um stündliche, inkrementelle Ladevorgänge zu unterstützen, die für jede StoreID unterschiedlich sind. Die Lösung muss die Speicherkosten minimieren.
Wie sollten Sie den Code vervollständigen? Wählen Sie dazu die entsprechenden Optionen im Antwortbereich aus.
HINWEIS: Jede richtige Auswahl zählt als ein Punkt.
Correct Answer:
Explanation:
Box 1: .partitionBy
Example:
df.write.partitionBy( " y " , " m " , " d " )
mode(SaveMode.Append)
parquet( " /data/hive/warehouse/db_name.db/ " + tableName)
Box 2: ( " Year " , " Month " , " Day " , " Hour " , " StoreID " )
Box 3: .parquet( " /Purchases " )
Reference:
https://intellipaat.com/community/11744/how-to-partition-and-write-dataframe-in-spark-without-deleting-partitions-with-no-new-data Basic Concept: This question tests monitor, configure, and optimize database resources in the DP-300 exam context. The correct choice is determined by the exact service boundary and operational requirement stated in the scenario.
Why the selected answer is Correct: The selected values fit this scenario because they apply the required Azure SQL configuration at the correct scope and sequence: Purchases will contain the following columns:
ProductID ItemPrice LineTotal Quantity StoreID Minute Month Hour Year Day You need to store the data to support hourly incremental load pipelines that will vary for each StoreID.
Why the alternate choices are Wrong: The alternate selections apply to different administrative stages or different scopes. In a hotspot or drag-drop task, order and scope are part of the answer, so a technically valid Azure feature can still be wrong if it is placed in the wrong step.
