NEW QUESTION # 189
A data analyst needs to create and deliver a dashboard that displays the company's financial transactions as they are updated. Which of the following delivery methods should the analyst consider? (Select two).

A. Time series
B. Dynamic
C. Real-time
D. Snapshot
E. Ad hoc
F. Static

Answer: B,C

Explanation:
This question is part of theVisualization and Reportingdomain, focusing on delivery methods for dashboards. The requirement for displaying financial transactions "as they are updated" implies a need for real-time updates and interactivity, which narrows down the options.
* Real-time (Option A): Real-time delivery ensures the dashboard reflects the latest data as transactions are updated, meeting the requirement.
* Snapshot (Option B): A snapshot provides a static view at a specific point, not suitable for ongoing updates.
* Dynamic (Option C): A dynamic dashboard allows for interactivity and can be updated as data changes, complementing real-time delivery.
* Static (Option D): Static dashboards don't update automatically, making this incorrect.
* Ad hoc (Option E): Ad hoc delivery is for one-time reports, not ongoing updates.
* Time series (Option F): Time series refers to a data type or visualization, not a delivery method.
The DA0-002 Visualization and Reporting domain includes understanding "the appropriate visualization in the form of a report or dashboard" with delivery methods Real-time and dynamic methods best support the need for updated financial transaction dashboards.

NEW QUESTION # 190
A data analyst needs to remove all duplicate values between two tables, "Employees" and "Managers," using SQL SELECT statements. Which of the following should the analyst use for this task?

A. SELECT * FROM Employees JOIN SELECT * FROM Managers
B. SELECT * FROM Employees CROSS JOIN SELECT * FROM Managers
C. SELECT * FROM Employees UNION ALL SELECT * FROM Managers
D. SELECT * FROM Employees UNION SELECT * FROM Managers

Answer: D

Explanation:
This question pertains to theData Acquisition and Preparationdomain, focusing on combining and deduplicating data using SQL. The task is to remove duplicates between two tables, meaning the analyst needs a unique set of records from both.
* SELECT * FROM Employees UNION ALL SELECT * FROM Managers (Option A): UNION ALL combines all rows from both tables, including duplicates, which doesn't meet the requirement.
* SELECT * FROM Employees UNION SELECT * FROM Managers (Option B): UNION combines rows from both tables and automatically removes duplicates, providing a unique set of records, which fits the task.
* SELECT * FROM Employees JOIN SELECT * FROM Managers (Option C): This syntax is incorrect; a JOIN requires an ON clause, and it wouldn't remove duplicates.
* SELECT * FROM Employees CROSS JOIN SELECT * FROM Managers (Option D): A CROSS JOIN creates a Cartesian product, resulting in all possible combinations, not removing duplicates.
The DA0-002 Data Acquisition and Preparation domain includes "executing data manipulation," and UNION is the correct SQL operation for combining tables while removing duplicates.
