According to the SAP Help Portal1, SVG (Scalable Vector Graphics) is the recommended image file type for optimal story performance in SAP Analytics Cloud Story Design. SVG is a vector-based format that can scale to any size without losing quality or clarity. SVG images also have a smaller file size than other image formats, such as JPEG, PNG, or BMP, which are raster-based formats that store pixel dat

a. Raster images can lose quality or become blurry when scaled up or down, and they also have a larger file size than vector images.Therefore, using SVG images can improve the loading speed and responsiveness of your stories, as well as the visual appearance of your images2.

When converting a story to Optimized Design Experience, you need to be aware that some elements that are available in the Classic Design Experience are not yet supported in the Optimized Design Experience. These elements include:

Grid pages

Linked analysis

Geo maps

Images

Shapes

Texts

Buttons

Input controls

Value driver trees

Explorer

If your story contains any of these elements, you will receive a warning message before converting the story, informing you that these elements will be permanently deleted from the story. You can choose to proceed with the conversion or cancel it.If you proceed, the unsupported elements will be removed from the story, and you will not be able to restore them1.

The correct answers are C. Have a clear message and D. Use corporate branding standards. These are some of the guidelines that SAP recommends you follow when you create a story.According to the course material1, ''Your current reporting and dashboard standards will suffice for SAP Analytics Cloud stories.And if you do not have reporting or dashboard standards, this is the perfect time to create them.'' The course material also suggests that you should ''have a clear message and purpose for your story'' and 'use corporate branding standards to ensure consistency and professionalism'1.

The other options are not mentioned as guidelines in the course material. Option

A) Use grouping is a feature that allows you to group data points in a chart or table, but it is not a general design principle. Option B. Avoid pie charts is a common advice for data visualization, but it is not specific to SAP Analytics Cloud stories.

The calculation types that support input controls are restricted measure, calculated measure, and difference from. A restricted measure is a measure that is filtered by one or more dimensions. A calculated measure is a measure that is derived from an expression using other measures and dimensions. A difference from is a measure that shows the difference between two values based on another dimension. Dimension to measure and aggregation are not calculation types; they are functions that can be used in calculations. Verified Reference: [SAP Analytics Cloud - Input Controls]

An input control is a type of filter that allows you to dynamically change the values of dimensions or measures in your story or application.You can use an input control to filter dimension or measure values and select dimension or measure values for your widgets, such as charts, tables, or geo maps1.For example, you can create an input control that lets you choose which product category or year to display in your chart2.

You cannot use an input control to define a prompt or explore data relationships. A prompt is a filter that is applied to a model before the data is loaded into a story or an application. Prompts allow you to select the data that you want to see in your story or application.You can create prompts in the modeler, not in the story or application3. To explore data relationships, you can use the Smart Discovery feature, which allows you to automatically generate insights and visualizations based on your dat

a.You can access Smart Discovery from the context menu of a chart or table widget4.
