Tableau Data Analyst Certification Practice Test 2025 – Complete Exam Preparation

Using device layouts for the dashboard is the optimal method to ensure accessibility on both computers and mobile devices. Device layouts allow analysts to customize the dashboard’s presentation based on the specific dimensions and capabilities of different devices. This means that you can design a unique layout that is optimized for how users will interact with the dashboard on mobile screens—often providing a different arrangement or more simplified view compared to what is displayed on a larger computer monitor.

Implementing separate dashboards for each device would lead to increased maintenance effort and potential inconsistency in your data storytelling. Using a single layout for all devices might not deliver the best user experience, especially on smaller screens, as it may not take full advantage of the mobile format, making it harder for users to navigate and comprehend the data. Simply adjusting the resolution of the dashboard won't adequately address the layout challenges that arise from different screen sizes and user interactions. Therefore, choosing device layouts strikes the best balance between usability and design fidelity across various platforms.
