NEW QUESTION # 158
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).

Answer: B,D

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.

* 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.

* Pie (Option B): Pie charts are ideal for showing proportions or percentages of a whole, such as revenue distribution across departments, making this the best choice.
