NEW QUESTION # 82
You have an Azure Databricks workspace that is enabled for Unity Catalog and contains a Delta table named Orders.
You load the Orders table into an Apache Spark DataFrame named df.
You need to create a DataFrame that excludes rows where the order amount is null.
Solution: You run the following expression.
df.filter(df.order_amount.isNotNull())
Does this meet the goal?
Answer: B
Explanation:
The correct answer is A - Yes.
df.filter(df.order_amount.isNotNull()) is the correct PySpark pattern for excluding null rows. The isNotNull() method is a Column method that returns True for every row where order_amount has a value and False for rows where it is null. Spark ' s filter keeps only the rows where the condition evaluates to True, producing a DataFrame with all null order_amount rows removed.
This works correctly because isNotNull() is explicitly null-aware - unlike the != None comparison in Q52, it doesn ' t rely on Python equality semantics. Under the hood it maps to the SQL expression order_amount IS NOT NULL, which is unambiguous in both SQL and Spark.
Both df.filter(df.order_amount.isNotNull()) and df.dropna(subset=[ ' order_amount ' ]) produce identical results. The choice between them is stylistic - isNotNull() reads more explicitly as a filter condition, while dropna is more compact when handling multiple columns.

NEW QUESTION # 83
You have an Azure Databricks workspace that contains a job in Lakeflow Jobs named Job1. Job1 contains multiple tasks.
Failures of non-critical tasks must be logged but must NOT trigger notifications. Notifications must be triggered only when critical tasks have failed, and Job1 has completed You need to configure the job alerting behavior.
What should trigger a notification?
Answer: C
Explanation:
The correct answer is B - a job failure.
The requirement draws a clear line: non-critical task failures should be logged silently; notifications should only fire when a critical failure causes the whole job to stop. Configuring the alert on 'Job Failure' achieves this precisely - the notification triggers when the job itself reaches a Failed terminal state, which only happens when at least one critical task has failed and the job cannot complete.
Option A (task failure) would send a notification for every task-level failure, including non-critical ones.
That's exactly the noise the question wants to avoid. Option C (job success) would never alert on failures at all. Option D (task success) confirms completion but doesn't catch failures.
Setting alerting at the job level rather than the task level is also simpler to configure - you don't need to mark individual tasks as critical or non-critical in the notification settings.

NEW QUESTION # 84
You have an Azure Databricks workspace that is enabled for Unity Catalog.
You have a Lakeflow Spark Declarative Pipelines (SDP) pipeline that writes numerical data to a table named Table1 by using a data quality validation rule named rule1.
You need to modify rule1 to meet the following requirements:
* Ensure that amount is always greater than 0.
* Fail the pipeline update for Table1 when data that violates rule1 is detected.
Which statement should you execute?
Answer: A
Explanation:
The expect_or_fail decorator validates every incoming record against the expression amount > 0 and stops the table update when a violation occurs. This exactly meets the requirement that invalid data cause the pipeline update to fail. Option A applies multiple expectations and drops violating records instead of failing the update. Option B also discards invalid records while allowing valid records to continue processing. Option D records expectation metrics but retains invalid records and allows the update to continue. These alternative behaviors are useful when invalid data can be tolerated, quarantined, or monitored, but they do not satisfy strict enforcement. The fail action provides transactional protection because the affected update does not successfully publish data that violates the stated quality rule.
NEW QUESTION # 85
A data engineer notices slow query performance on a large Delta table in Azure Databricks. The table has frequent updates and deletes. Which action best improves query performance?
Answer: A
Explanation:
OPTIMIZE compacts small files into larger ones, reducing file scan overhead. ZORDER improves data skipping by co-locating related column values. This combination significantly improves query performance on frequently filtered columns. Increasing cluster size does not address file fragmentation. Converting to Parquet removes Delta benefits like ACID transactions.
NEW QUESTION # 86
Which tool is best for continuous ingestion of files landing in Azure Data Lake?
Answer: D
Explanation:
Auto Loader is optimized for incremental and continuous ingestion from cloud storage. It detects new files automatically and scales efficiently. Databricks Jobs schedule tasks but do not handle file detection. Logic Apps are workflow tools. ADF is batch-oriented.
