Databricks Certified Data Engineer Associate Exam Sample Questions (Q246-Q251):

NEW QUESTION # 246
A data engineer is working on a Databricks project that utilizes cloud storage. The data engineer wants to load several json files from containers on a storage account as soon as the file arrives within the storage account.
Which syntax should the data engineer follow to first load the files into a dataframe and check that it is working as expected using Python?

A. df = spark.read.json("inp i./path")
B. df = spark.readStream.format("json").load("input/path")
C. df = spark.readStream.format("cloudFiles") .option("cloudFiles.format", "json") .load("/input/path")
D. df = spark.readStream.format("cloud"),option("json").load("/input/path")

Answer: C

NEW QUESTION # 247
A data engineer needs to optimize the data layout and query performance for an e-commerce transactions Delta table. The table is partitioned by "purchase_date" a date column which helps with time-based queries but does not optimize searches on user statistics "customer_id", a high-cardinality column.
The table is usually queried with filters on "customer_i
d" within specific date ranges, but since this data is spread across multiple files in each partition, it results in full partition scans and increased runtime and costs.
How should the data engineer optimize the Data Layout for efficient reads?

A. Alter the table implementing liquid clustering by "customer_id" and "purchase_date".
B. Alter table implementing liquid clustering on "customerid" while keeping the existing partitioning.
C. Alter the table to partition by "customer_id".
D. Enable delta caching on the cluster so that frequent reads are cached for performance.

Answer: A

NEW QUESTION # 248
In which of the following file formats is data from Delta Lake tables primarily stored?

A. JSON
B. CSV
C. Parquet
D. Delta
E. A proprietary, optimized format specific to Databricks

Answer: C

Explanation:
Delta Lake is an open source project that provides ACID transactions, time travel, and other features on top of Apache Parquet, a columnar file format that is widely used for big data analytics. Delta Lake uses versioned Parquet files to store your data in your cloud storage, along with JSON files as transaction logs and checkpoint files to track the changes and ensure data integrity. Delta Lake is compatible with any Apache Hive compatible file format, such as CSV, JSON, or AVRO, but it primarily stores data as Parquet files for better performance and compression.

A. At least one notebook library to be executed
B. A path to cloud storage location for the written data
C. The preferred DBU/hour cost
D. A location of a target database for the written data
E. A key-value pair configuration

Answer: A

NEW QUESTION # 250
A data engineer uploads a CSV file using the "Create or modify a table using file upload" option in Databricks. To avoid incorrect schema inference, they disable Automatically detect column types before creating a Unity Catalog-managed table. What is the outcome?

A. Previously inferred column types are preserved.
B. All columns are created with the STRING data type.
C. Table creation fails because column types are not specified.
D. Numeric columns are inferred as numeric types; others are STRING.

Answer: B

Explanation:
Disabling Automatically detect column types causes Databricks to create every uploaded CSV column as STRING, avoiding automatic numeric, date, or Boolean inference.
