Databricks Certified Data Analyst Associate Exam 認定 Databricks-Certified-Data-Analyst-Associate 試験問題 (Q75-Q80):

質問 # 75
A data analyst needs to share a Databricks SQL dashboard with stakeholders that are not permitted to have accounts in the Databricks deployment. The stakeholders need to be notified every time the dashboard is refreshed.
Which approach can the data analyst use to accomplish this task with minimal effort/

A. By adding the stakeholders ' email addresses to the refresh schedule subscribers list
B. By granting the stakeholders ' email addresses permissions to the dashboard
C. By granting the stakeholders ' email addresses to the SQL Warehouse (formerly known as endpoint) subscribers list
D. By downloading the dashboard as a PDF and emailing it to the stakeholders each time it is refreshed

正解：A

解説：
To share a Databricks SQL dashboard with stakeholders who do not have accounts in the Databricks deployment and ensure they are notified upon each refresh, the data analyst can add the stakeholders ' email addresses to the dashboard ' s refresh schedule subscribers list. This approach allows the stakeholders to receive email notifications containing the latest dashboard updates without requiring them to have direct access to the Databricks workspace. This method is efficient and minimizes effort, as it automates the notification process and ensures stakeholders remain informed of the most recent data insights.
Reference: Manage scheduled dashboard updates and subscriptions

質問 # 76
A data analyst has a managed table table_name in database database_name. They would now like to remove the table from the database and all of the data files associated with the table. The rest of the tables in the database must continue to exist.
Which of the following commands can the analyst use to complete the task without producing an error?

A. DELETE TABLE table_name FROM database_name;
B. DROP TABLE table_name FROM database_name;
C. DROP TABLE database_name.table_name;
D. DROP DATABASE database_name;
E. DELETE TABLE database_name.table_name;

正解：C

質問 # 77
A data analyst is using Databricks Unity Catalog. The datasets are tagged by sensitivity, and confidential data is marked with the tag key confidential. The data analyst needs to quickly find all tables tagged as confidential to review their access permissions in the Databricks workspace search bar.
Which search key text should the data analyst use to find these tables?

A. tag=confidential
B. confidential:true
C. tag:confidential
D. search tag = ' confidential '

正解：C

解説：
The correct answer is C because the tag key is confidential, and Databricks workspace search uses the syntax tag: < tag_key > to search by tag key. Therefore, the correct search text is tag:confidential. Option A uses a Boolean-style syntax that is not the documented Databricks tag search syntax. Option B uses an equals sign, and Option D is not valid workspace search syntax.
Official documentation extract used: Databricks states that to search by tag key alone, use the syntax tag: < tag_key > .

質問 # 78
Data professionals with varying titles use the Databricks SQL service as the primary touchpoint with the Databricks Lakehouse Platform. However, some users will use other services like Databricks Machine Learning or Databricks Data Science and Engineering.
Which of the following roles uses Databricks SQL as a secondary service while primarily using one of the other services?

A. Business analyst
B. Data engineer
C. Data analyst
D. Business intelligence analyst
E. SQL analyst

正解：B

解説：
Data engineers are primarily responsible for building, managing, and optimizing data pipelines and architectures. They use Databricks Data Science and Engineering service to perform tasks such as data ingestion, transformation, quality, and governance. Data engineers may use Databricks SQL as a secondary service to query, analyze, and visualize data from the lakehouse, but this is not their main focus.

質問 # 79
A data analyst has been asked to count the number of customers in each region and has written the following query:

If there is a mistake in the query, which of the following describes the mistake?

A. The query is using ORDER BY. which is not allowed in an aggregation.
B. The query is using count( ' ). which will count all the customers in the customers table, no matter the region.
C. The query is selecting region but region should only occur in the ORDER BY clause.
D. There are no mistakes in the query.
E. The query is missing a GROUP BY region clause.

正解：E

解説：
In the provided SQL query, the data analyst is trying to count the number of customers in each region.
However, they made a mistake by not including the "GROUP BY" clause to group the results by region.
Without this clause, the query will not return counts for each distinct region but rather an error or incorrect result. References: The need for a GROUP BY clause in such queries can be understood from Databricks SQL documentation: Databricks SQL.
I also noticed that you uploaded an image with your question. The image shows a snippet of an SQL query written in plain text on a white background. The query is attempting to select regions and count customers from a "customers" table and order the results by region. There's no visible syntax highlighting or any other color - it's monochromatic. The query is the same as the one in your question. I'm not sure why you included the image, but maybe you wanted to show me the exact format of your query. If so, you can also use code blocks to display formatted content such as SQL queries. For example, you can write:
SELECT region, count(*) AS number_of_customers
FROM customers
ORDER BY region;
This way, you can avoid uploading images and make your questions more clear and concise. I hope this helps.
