Microsoft Implementing Data Engineering Solutions Using Azure Databricks Sample Questions (Q63-Q68):

NEW QUESTION # 63
What happens if incoming data violates Delta table schema?

A. Data is appended with nulls
B. Table is overwritten
C. Data is automatically cast
D. Data is rejected

Answer: D

Explanation:
Delta Lake enforces schema by default. If incoming data does not match schema, the write operation fails unless schema evolution is explicitly enabled. It does not auto-cast or append invalid data. Overwriting would require explicit command.

NEW QUESTION # 64
You have an Apache Spark DataFrame named salesDF that contains the following columns:
* Product
* Region
* Sales
* Date
You need to create a pivot table that shows the total sales by product for each region.
How should you complete the PySpark code segment? To answer, drag the appropriate values to the correct targets. Each value may be used once, more than once, or not at all. You may need to drag the split bar between panes or scroll to view content.
NOTE: Each correct selection is worth one point.

Answer:

Explanation:

Explanation:
* groupBy
* pivot
The groupBy( " Region " ) operation establishes one aggregation group for each geographical region in the DataFrame. The subsequent pivot( " Product " ) operation converts every distinct Product value into a separate output column. Finally, agg(F.sum( " Sales " )) calculates the total sales for every product within each region. The resulting DataFrame contains one row per region and one column for each product, with the corresponding aggregated sales value. cogroup combines grouped datasets and is not used for creating a conventional pivot table. coalesce controls the number of DataFrame partitions or replaces null values, depending on its context. The sum function is already provided inside the aggregation expression and therefore is not required in either blank.

NEW QUESTION # 65
You have an Azure Databricks workspace that is enabled for Unity Catalog.
You plan to ingest data from CSV files stored in Azure Data Lake Storage Gen2. New rows are appended frequently.
You need to implement a data ingestion solution that meets the following requirements:
- New data must be available in near-real-time (NRT).
- The data must be stored in managed Delta tables.
- The solution must minimize custom code and maintenance effort.
What should you include in the solution?

A. scheduled Apache Spark batch jobs
B. Auto Loader
C. an external table that references the CSV files
D. an Azure Data Factory pipeline

Answer: B

Explanation:
You should use Auto Loader with Delta Live Tables (DLT) or a streaming readStream using the cloudFiles format to load data into Unity Catalog managed tables.
To achieve the absolute lowest maintenance and custom code, Delta Live Tables with Auto Loader is the recommended choice.
Configure Cloud FilesFormat option: Set the source format to cloudFiles in your Spark stream.File detection: Auto Loader automatically tracks new files arriving in Azure Data Lake Storage (ADLS) Gen2.Schema evolution: It infers and adapts to schema changes without code updates.

NEW QUESTION # 66
You have an Azure Databricks workspace.
You have an Apache Spark Structured Streaming job named Job1 that processes data continuously and fails periodically due to transient errors.
You need to ensure that Job1 meets the following requirements:
- Resumes processing from the point that Job1 failed
- Minimizes how long it takes to restart Job1
- Minimizes the costs to restart Job1
What should you do?

A. Add an alert and manually restart Job1.
B. Implement checkpointing.
C. Decrease the retry interval.
D. Increase the minimum number of nodes in the cluster.

Answer: B

Explanation:
You must use checkpointing.
Checkpointing is the native Apache Spark mechanism designed specifically to handle failures in Structured Streaming jobs. It saves the exact execution state and progress to cloud storage (like Azure Data Lake Storage), allowing the job to resume precisely where it left off without data loss.
Resumes from Failure Point: The checkpoint directory stores the stream offsets. When restarted, Spark reads these offsets to pick up exactly where it failed.
Minimizes Restart Time: By saving the state, Spark does not need to recompute historical streaming data or re-evaluate the entire stream architecture from scratch.
Minimizes Restart Costs: It prevents the reprocessing of duplicate data, saving valuable cluster compute time and reducing cloud infrastructure costs.

NEW QUESTION # 67
Hotspot Question
You have an Azure Databricks job named Job1 that contains an ingestion task named Task1 and transformation task named Task2.
You need to ensure that if Task1 fails, the task retries automatically, and Task2 is prevented from running.
How should you configure Job1? To answer, select the appropriate options in the answer area.
