You are a Power Bl specialist at your organization.

Solution: Add a detailed description of how you defined margin.
Does this solution meet the goal?
A. Yes
B. No
Answer: B
Explanation:
In the modelling section, you can add a description within the properties of a column. A description is helpful for other modellers to understand the purpose of the column. However, this description does not have any impact on how Q&A interprets synonyms.

To avoid loading the query to the model, ensure that you disable query load in these instances.

B. You are missing an R package.
C. The visual has too many rows.
D. The resolution is too high.

Additionally, the input data has a limit of 250 MB. The version of the plotly will not affect the number of rows. All R visuals are limited to 150,000 rows. If you are missing an R package, no image will show and you will only get an error message. R visuals are all displayed at a 72 DPI resolution. The resolution does not affect the number of rows that can be plotted.

You have a line chart that shows units manufactured by month. You want to add the on-time delivery metric for each month when you hover the mouse over a data point. How would you provide the additional piece of data?
A. Add on-time delivery to the drill through fields.
B. Add the on-time delivery column to the secondary values field.
C. Add on-time delivery column to the tooltips field.
D. Add the on-time delivery column to the small multiples field.

A tooltip is a way of providing more contextual information and detail to data points on a visual. When you hover over a data point, the tooltip data will show. Answer A is incorrect. Drillthrough fields do not show on hover. When report readers use a drillthrough, they right-click a data point in other report pages, and drillthrough to the focused page to get details that is filtered to that context. Answer B is incorrect. A secondary values field is used to show other numeric data on a line chart. Answer B is incorrect. Small multiple is used to split your visuals into multiple smaller visuals, based on your selected fields.

NEW QUESTION 19
You work for a computer accessories company and your data model contains the following tables:
1. Accessories table: 1k rows that are updated monthly.
2. Sales table: 15M rows that are updated regularly with changes that need to be shown immediately.
3. Date table: 10k rows that are updated rarely.
For the three tables ABOVE, which storage mode should you use from the below options?
– Import
– DirectQuery
– Dual
A. Accessories: Import/Sales: DirectQuery/Date: Dual
B. Accessories: Import/Sales: DirectQuery/Date: Import
C. Accessories: DirectQuery/Sales: Import/Date: DirectQuery
D. Accessories: Dual/Sales: Import/Date: DirectQuery
Answer: B
Explanation:
For the accessories and date table you should use the import storage model. Imported tables with this setting are cached. Queries submitted to the Power BI dataset that return data from Import tables can be fulfilled only from cached data. The import method is used for static or low volume data. The sales table should use the DirectQuery storage mode. Tables with this setting are not cached. Queries that you submit to the Power BI dataset from DirectQuery tables can be fulfilled only by executing on-demand queries to the data source. Use DirectQuery when you have a large data set with millions of rows that need to be shown immediately in the report. You should not use the dual storage model. Dual storage tables can act as either cached or not cached, depending on the context of the query that’s submitted to the Power BI dataset.
NEW QUESTION 20
You work for a consulting company that has a contract with a large government department. Part of the requirements for the report is to configure the page for use with a screen reader for sight-impaired users. What should you configure in your report such that the page follows a logical sequence?
A. Bookmarks.
B. Tab order.
C. Filters on all pages.
D. Layer order.
Answer: B
Explanation:
The tab order is used by keyboard users to navigate the report page. Screen reader and accessibility software follow the sequence of tab order. You should not use bookmarks on your report for this purpose. Bookmarks save the current filters and slicers, cross-highlighted visuals, sort order. You should not use Filters on all pages. Filters select a subset of your data and do not help with accessibility. You should not use layer order. The layer order is used to control the order in which visuals are shown and is used if you visuals that overlap.
