Databricks Databricks-Certified-Data-Engineer-Professional Exam Syllabus Topics:

Databricks Certified Data Engineer Professional Sample Questions:

1. Which of the following technologies can be used to identify key areas of text when parsing Spark Driver log4j output?

A) Scala Datasets
B) Julia
C) pyspsark.ml.feature
D) C++
E) Regex

2. A data engineer is optimizing a managed Delta table that suffers from data skew and frequently changing query filter columns. The engineer wants to avoid costly data rewrites when query patterns evolve. The table size is under 1 TB. How should the data engineer meet this requirement?

A) Use Hive-style partitioning, as it provides efficient data skipping and is easy to change partition columns at any time.
B) Apply Z-ordering, since it allows flexible reorganization of data layout without rewriting existing files and adapts easily to new filter columns.
C) Enable liquid clustering, as it efficiently handles data skew, allows clustering keys to be changed without rewriting existing data, and adapts to evolving query patterns.
D) Combine partitioning and Z-ordering to maximize flexibility and minimize maintenance as query patterns change.

3. Incorporating unit tests into a PySpark application requires upfront attention to the design of your jobs, or a potentially significant refactoring of existing code.
Which statement describes a main benefit that offset this additional effort?

A) Troubleshooting is easier since all steps are isolated and tested individually
B) Ensures that all steps interact correctly to achieve the desired end result
C) Improves the quality of your data
D) Yields faster deployment and execution times
E) Validates a complete use case of your application

4. Given the following PySpark code snippet in a Databricks notebook:
filtered_df = spark.read.format("delta").load("/mnt/data/large_table")
\
.filter("event_date > '2024-01-01'")
filtered_df.count()
The data engineer notices from the Query Profiler that the scan operator for filtered_df is reading almost all files, despite the filter being applied.
What is the probable reason for poor data skipping?

A) The filter is executed only after the full data scan, preventing data skipping.
B) The filter condition involves a data type excluded from data skipping support.
C) The Delta table lacks optimization that enables dynamic file pruning.
D) The event_date column is outside the table's partitioning and Z-ordering scheme.

5. A task orchestrator has been configured to run two hourly tasks. First, an outside system writes Parquet data to a directory mounted at /mnt/raw_orders/. After this data is written, a Databricks job containing the following code is executed:

Assume that the fields customer_id and order_id serve as a composite key to uniquely identify each order, and that the time field indicates when the record was queued in the source system.
If the upstream system is known to occasionally enqueue duplicate entries for a single order hours apart, which statement is correct?

A) The orders table will not contain duplicates, but records arriving more than 2 hours late will be ignored and missing from the table.
B) Duplicate records enqueued more than 2 hours apart may be retained and the orders table may contain duplicate records with the same customer_id and order_id.
C) The orders table will contain only the most recent 2 hours of records and no duplicates will be present.
D) All records will be held in the state store for 2 hours before being deduplicated and committed to the orders table.
E) Duplicate records arriving more than 2 hours apart will be dropped, but duplicates that arrive in the same batch may both be written to the orders table.
