최신 Data Analyst Databricks-Certified-Data-Analyst-Associate 무료샘플문제 (Q98-Q103):

질문 # 98
Which of the following statements about adding visual appeal to visualizations in the Visualization Editor is incorrect?

A. Visualization scale can be changed.
B. Tooltips can be formatted.
C. Colors can be changed.
D. Data Labels can be formatted.
E. Borders can be added.

정답：E

설명：
The Visualization Editor in Databricks SQL allows users to create and customize various types of charts and visualizations from the query results. Users can change the visualization type, select the data fields, adjust the colors, format the data labels, and modify the tooltips. However, there is no option to add borders to the visualizations in the Visualization Editor. Borders are not a supported feature of the new chart visualizations in Databricks1. Therefore, the statement that borders can be added is incorrect. References:

질문 # 99
Which of the following data workloads will utilize a Gold table as its source?

A. A job that aggregates uncleaned data to create standard summary statistics.
B. A job that cleans data by removing malformatted records.
C. A job that enriches data by parsing its timestamps into a human-readable format.
D. A job that queries aggregated data designed to feed into a dashboard.
E. A job that ingests raw data from a streaming source into the Lakehouse.

정답：D

설명：
Option D is correct. Gold tables are refined, business-ready datasets used for analytics, dashboards, reporting, and other downstream consumption. A workload that queries aggregated data designed to feed a dashboard is therefore using Gold-layer data. Raw streaming ingestion belongs to Bronze, cleaning malformed records belongs to Silver, and aggregating uncleaned data is not the recommended Gold pattern. Official Databricks extract: the Gold layer "consists of aggregated data tailored for analytics and reporting" and is optimized for
"queries and dashboards."

질문 # 100
A data analyst has created a Query in Databricks SQL, and now wants to create two data visualizations from that Query and add both of those data visualizations to the same Databricks SQL Dashboard.
Which step will the data analyst need to take when creating and adding both data visualizations to the Databricks SQL Dashboard?

A. Alter the Query to return two separate sets of results.
B. Decide on a single data visualization to add to the dashboard.
C. Add two separate visualizations to the dashboard based on the same Query.
D. Copy the Query and create one data visualization per query.

정답：C

질문 # 101
The stakeholders.customers table has 15 columns and 3,000 rows of data. The following command is run:

After running SELECT * FROM stakeholders.eur_customers, 15 rows are returned. After the command executes completely, the user logs out of Databricks.
After logging back in two days later, what is the status of the stakeholders.eur_customers view?

A. The view has been converted into a table.
B. The view has been dropped.
C. The view is not available in the metastore, but the underlying data can be accessed with SELECT * FROM delta. `stakeholders.eur_customers`.
D. The view remains available but attempting to SELECT from it results in an empty result set because data in views are automatically deleted after logging out.
E. The view remains available and SELECT * FROM stakeholders.eur_customers will execute correctly.

정답：E

설명：
In Databricks, a view is a saved SQL query definition that references existing tables or other views. Once created, a view remains persisted in the metastore (such as Unity Catalog or Hive Metastore) until it is explicitly dropped.
Key points:
* Views do not store data themselves but reference data from underlying tables.
* Logging out or being inactive does not delete or alter views.
* Unless a user or admin explicitly drops the view or the underlying data/table is deleted, the view continues to function as expected.
* Therefore, after logging back in-even days later-a user can still run SELECT * FROM stakeholders.
eur_customers, and it will return the same data (provided the underlying table hasn't changed).

질문 # 102
In which of the following situations should a data analyst use higher-order functions?

A. When custom logic needs to be applied to simple, unnested data
B. When custom logic needs to be converted to Python-native code
C. When built-in functions are taking too long to perform tasks
D. When built-in functions need to run through the Catalyst Optimizer
E. When custom logic needs to be applied at scale to array data objects

정답：E

설명：
Higher-order functions are a simple extension to SQL to manipulate nested data such as arrays. A higher-order function takes an array, implements how the array is processed, and what the result of the computation will be. It delegates to a lambda function how to process each item in the array. This allows you to define functions that manipulate arrays in SQL, without having to unpack and repack them, use UDFs, or rely on limited built-in functions. Higher-order functions provide a performance benefit over user defined functions.
