질문 # 193
The default threshold of VACUUM is 7 days, internal audit team asked to certain tables to maintain at least
365 days as part of compliance requirement, which of the below setting is needed to implement.

A. ALTER TABLE table_name set EXENDED TBLPROPERTIES (del-ta.deletedFileRetentionDuration=
'interval 365 days')
B. ALTER TABLE table_name set TBLPROPERTIES (del-ta.deletedFileRetentionDuration= 'interval 365 days')
C. ALTER TABLE table_name set EXENDED TBLPROPERTIES (delta.vaccum.duration= 'interval 365 days')
D. MODIFY TABLE table_name set TBLPROPERTY (delta.maxRetentionDays = 'inter-val 365 days')

정답：B

설명：
Explanation
1.ALTER TABLE table_name SET TBLPROPERTIES ( property_key [ = ] property_val [, ...] ) TBLPROPERTIES allow you to set key-value pairs Table properties and table options (Databricks SQL) | Databricks on AWS

질문 # 194
The security team is exploring whether or not the Databricks secrets module can be leveraged for connecting to an external database.
After testing the code with all Python variables being defined with strings, they upload the password to the secrets module and configure the correct permissions for the currently active user. They then modify their code to the following (leaving all other variables unchanged).

Which statement describes what will happen when the above code is executed?

A. The connection to the external table will succeed; the string value of password will be printed in plain text.
B. The connection to the external table will fail; the string "redacted" will be printed.
C. An interactive input box will appear in the notebook; if the right password is provided, the connection will succeed and the encoded password will be saved to DBFS.
D. An interactive input box will appear in the notebook; if the right password is provided, the connection will succeed and the password will be printed in plain text.
E. The connection to the external table will succeed; the string "redacted" will be printed.

정답：E

설명：
This is the correct answer because the code is using the dbutils.secrets.get method to retrieve the password from the secrets module and store it in a variable. The secrets module allows users to securely store and access sensitive information such as passwords, tokens, or API keys. The connection to the external table will succeed because the password variable will contain the actual password value. However, when printing the password variable, the string "redacted" will be displayed instead of the plain text password, as a security measure to prevent exposing sensitive information in notebooks.

"Secrets" section.

질문 # 195
A Spark job is taking longer than expected. Using the Spark UI, a data engineer notes that the Min, Median, and Max Durations for tasks in a particular stage show the minimum and median time to complete a task as roughly the same, but the max duration for a task to be roughly 100 times as long as the minimum.
Which situation is causing increased duration of the overall job?

A. Skew caused by more data being assigned to a subset of spark-partitions.
B. Spill resulting from attached volume storage being too small.
C. Network latency due to some cluster nodes being in different regions from the source data
D. Credential validation errors while pulling data from an external system.
E. Task queueing resulting from improper thread pool assignment.

정답：A

설명：
This is the correct answer because skew is a common situation that causes increased duration of the overall job. Skew occurs when some partitions have more data than others, resulting in uneven distribution of work among tasks and executors. Skew can be caused by various factors, such as skewed data distribution, improper partitioning strategy, or join operations with skewed keys. Skew can lead to performance issues such as long-running tasks, wasted resources, or even task failures due to memory or disk spills. Verified References: [Databricks Certified Data Engineer Professional], under "Performance Tuning" section; Databricks Documentation, under "Skew" section.

질문 # 196
A healthcare analytics team is implementing a dimensional model in Delta Lake for patient care analysis. They have a date dimension table and are evaluating design options to ensure it supports a wide range of time-based analyses.
Which design approach for the date dimension will support efficient time-based querying and aggregation?

A. Store only the date value and calculate all time attributes dynamically in queries.
B. Create separate dimension tables for different calendar systems (fiscal, academic, etc.).
C. Store the date as a string in the format YYYY-MM-DD for readability.
D. Pre-calculate attributes like fiscal_period, quarter, month_name, day_of_week, and holiday.

정답：D

설명：
Comprehensive and Detailed Explanation From Exact Extract of Databricks Data Engineer Documents:
In dimensional modeling, Databricks recommends denormalized, attribute-rich dimension tables for performance and usability. A date dimension should include all commonly used derived time attributes such as fiscal period, quarter, month, weekday, and holiday flags. Precomputing these attributes ensures consistent business logic, eliminates repeated calculations during query time, and enables efficient filtering and aggregation. The documentation for Delta Lake and Lakehouse design explicitly advises precomputing these attributes for analytical workloads that depend heavily on time-based slicing. Options A and C degrade performance and consistency, while maintaining multiple calendar-specific dimension tables (B) complicates the model unnecessarily.

질문 # 197
You were asked to create or overwrite an existing delta table to store the below transaction data.

A. 1.CREATE IF EXSITS REPLACE TABLE transactions (
2.transactionId int,
3.transactionDate timestamp,
4.unitsSold int)
B. 1.CREATE OR REPLACE DELTA TABLE transactions (
2.transactionId int,
3.transactionDate timestamp,
4.unitsSold int)
C. 1.CREATE OR REPLACE TABLE IF EXISTS transactions (
2.transactionId int,
3.transactionDate timestamp,
4.unitsSold int)
5.FORMAT DELTA
D. 1.CREATE OR REPLACE TABLE transactions (
2.transactionId int,
3.transactionDate timestamp,
4.unitsSold int)

정답：D

설명：
Explanation
The answer is
1.CREATE OR REPLACE TABLE transactions (
2.transactionId int,
3.transactionDate timestamp,
4.unitsSold int)
When creating a table in Databricks by default the table is stored in DELTA format.
