Databricks Certified Data Engineer Professional Exam Sample Questions (Q100-Q105):

NEW QUESTION # 100
Where in the Spark UI can one diagnose a performance problem induced by not leveraging predicate push-down?

  • A. In the Executor's log file, by gripping for "predicate push-down"
  • B. In the Stage's Detail screen, in the Completed Stages table, by noting the size of data read from the Input column
  • C. In the Query Detail screen, by interpreting the Physical Plan
  • D. In the Storage Detail screen, by noting which RDDs are not stored on disk
  • E. In the Delta Lake transaction log. by noting the column statistics

Answer: C

Explanation:
This is the correct answer because it is where in the Spark UI one can diagnose a performance problem induced by not leveraging predicate push-down. Predicate push-down is an optimization technique that allows filtering data at the source before loading it into memory or processing it further. This can improve performance and reduce I/O costs by avoiding reading unnecessary data. To leverage predicate push-down, one should use supported data sources and formats, such as Delta Lake, Parquet, or JDBC, and use filter expressions that can be pushed down to the source. To diagnose a performance problem induced by not leveraging predicate push-down, one can use the Spark UI to access the Query Detail screen, which shows information about a SQL query executed on a Spark cluster. The Query Detail screen includes the Physical Plan, which is the actual plan executed by Spark to perform the query. The Physical Plan shows the physical operators used by Spark, such as Scan, Filter, Project, or Aggregate, and their input and output statistics, such as rows and bytes. By interpreting the Physical Plan, one can see if the filter expressions are pushed down to the source or not, and how much data is read or processed by each operator.


NEW QUESTION # 101
A table named user_ltv is being used to create a view that will be used by data analysts on Get Latest & Actual Certified-Data-Engineer-Professional Exam's Question and Answers from various teams. Users in the workspace are configured into groups, which are used for setting up data access using ACLs.
The user_ltv table has the following schema:
email STRING, age INT, ltv INT
The following view definition is executed:

An analyst who is not a member of the marketing group executes the following query:
SELECT * FROM email_ltv
Which statement describes the results returned by this query?

  • A. Only the email and ltv columns will be returned; the email column will contain the string
    "REDACTED" in each row.
  • B. Three columns will be returned, but one column will be named "redacted" and contain only null values.
  • C. The email, age. and ltv columns will be returned with the values in user ltv.
  • D. Only the email and itv columns will be returned; the email column will contain all null values.
  • E. The email and ltv columns will be returned with the values in user itv.

Answer: A

Explanation:
The code creates a view called email_ltv that selects the email and ltv columns from a table called user_ltv, which has the following schema: email STRING, age INT, ltv INT. The code also uses the CASE WHEN expression to replace the email values with the string "REDACTED" if the user is not a member of the marketing group. The user who executes the query is not a member of the marketing group, so they will only see the email and ltv columns, and the email column will contain the string "REDACTED" in each row.


NEW QUESTION # 102
A Structured Streaming job deployed to production has been resulting in higher than expected cloud storage costs. At present, during normal execution, each microbatch of data is processed in less than 3s; at least 12 times per minute, a microbatch is processed that contains 0 records. The streaming write was configured using the default trigger settings. The production job is currently scheduled alongside many other Databricks jobs in a workspace with instance pools provisioned to reduce start-up time for jobs with batch execution.
Holding all other variables constant and assuming records need to be processed in less than 10 minutes, which adjustment will meet the requirement?

  • A. Set the trigger interval to 3 seconds; the default trigger interval is consuming too many records per batch, resulting in spill to disk that can increase volume costs.
  • B. Use the trigger once option and configure a Databricks job to execute the query every 10 minutes; this approach minimizes costs for both compute and storage.
  • C. Set the trigger interval to 500 milliseconds; setting a small but non-zero trigger interval ensures that the source is not queried too frequently.
  • D. Increase the number of shuffle partitions to maximize parallelism, since the trigger interval cannot be modified without modifying the checkpoint directory.
  • E. Set the trigger interval to 10 minutes; each batch calls APIs in the source storage account, so decreasing trigger frequency to maximum allowable threshold should minimize this cost.

Answer: E


NEW QUESTION # 103
All records from an Apache Kafka producer are being ingested into a single Delta Lake table with the following schema:
key BINARY, value BINARY, topic STRING, partition LONG, offset LONG, timestamp LONG There are 5 unique topics being ingested. Only the "registration" topic contains Personal Identifiable Information (PII). The company wishes to restrict access to PII. The company also wishes to only retain records containing PII in this table for 14 days after initial ingestion.
However, for non-PII information, it would like to retain these records indefinitely.
Which of the following solutions meets the requirements?

  • A. Data should be partitioned by the topic field, allowing ACLs and delete statements to leverage partition boundaries.
  • B. All data should be deleted biweekly; Delta Lake's time travel functionality should be leveraged to maintain a history of non-PII information.
  • C. Because the value field is stored as binary data, this information is not considered PII and no special precautions should be taken.
  • D. Data should be partitioned by the registration field, allowing ACLs and delete statements to be set for the PII directory.
  • E. Separate object storage containers should be specified based on the partition field, allowing isolation at the storage level.

Answer: A

Explanation:
By default partitionning by a column will create a separate folder for each subset data linked to the partition.


NEW QUESTION # 104
An upstream source writes Parquet data as hourly batches to directories named with the current date. A nightly batch job runs the following code to ingest all data from the previous day as indicated by the date variable:
Get Latest & Actual Certified-Data-Engineer-Professional Exam's Question and Answers from

Assume that the fields customer_id and order_id serve as a composite key to uniquely identify each order.
If the upstream system is known to occasionally produce duplicate entries for a single order hours apart, which statement is correct?

  • A. Each write to the orders table will only contain unique records; if existing records with the same key are present in the target table, these records will be overwritten.
  • B. Each write to the orders table will only contain unique records, but newly written records may have duplicates already present in the target table.
  • C. Each write to the orders table will run deduplication over the union of new and existing records, ensuring no duplicate records are present.
  • D. Each write to the orders table will only contain unique records, and only those records without duplicates in the target table will be written.
  • E. Each write to the orders table will only contain unique records; if existing records with the same key are present in the target table, the operation will tail.

Answer: B

Explanation:
This is the correct answer because the code uses the dropDuplicates method to remove any duplicate records within each batch of data before writing to the orders table. However, this method does not check for duplicates across different batches or in the target table, so it is possible that newly written records may have duplicates already present in the target table. To avoid this, a better approach would be to use Delta Lake and perform an upsert operation using mergeInto.
