Exam 70-778 topic 1 question 22 discussion

D&E are correct. 1- download and install R Services 2- specifying local R installation in the R Scripting section of the Options dialog box.

Two actions to be performed: 1- answer E -> Download Microsoft R 2- answer D -> Enable R visuals in Power BI Desktop So the correct answers are E & D

The part of the mentioned link says - "R visuals are created from R scripts, which might contain code with security or privacy risks. When attempting to view or interact with an R visual for the first time, a user is presented with a security warning message. Only enable R visuals if you trust the author and source, or after you review and understand the R script." Which means that we need to enable R visuals, if not R scripting.

A and E cannot be correct. R is not Microsoft. It is opensource. Answers are: B. Download and install RStudio Server on the computer that has Power BI Desktop installed. D. Enable R Scripting on the computer that has Power BI Desktop installed. After you've installed R, Power BI Desktop enables it automatically. However, when you insert the R Visual, it asks you to 'Enable Script Visuals'.

the correct answer is E, because in the documentation says that you only need to download and install R in the computer where you have Power BI Installed. After you've installed R, Power BI Desktop enables it automatically. This question was very confuse because says two actions, and I could undestand that like 2 options to check but not... this is the reference https://docs.microsoft.com/en-us/power-bi/create-reports/desktop-r-visuals

D & E.

You have to select 2 answers on this question per the instructions: Which two actions should you perform? Each correct answer presents part of the solution. NOTE: Each correct selection is worth one point. Therefore the correct answers are D&E

E: download & install R engine(Package) to PBI desktop; D: Enable R icon, open R script editor, copy and paste and Run. (included in package or otherwise downloaded separately); Ref Link: https://www.youtube.com/watch?v=Y88s8Vra_1g

E: download R engine to PBI desktop; D: download R script; Ref Link: https://www.youtube.com/watch?v=Y88s8Vra_1g

TWO actions as per question: "Which two actions should you perform? Each correct answer presents part of the solution."

E & D.

The answer is E. If you read the first 15 lines of https://docs.microsoft.com/en-us/power-bi/create-reports/desktop-r-visuals ... It says simply download and install R on the computer where Power BI desktop exists. It further says that Power BI automatically enables R once this is done.

D&E are correct. When using R for the firt time on the machine, you need to enable R after installing it.

E is correct. Says 2 actions: download and install

"After you've installed R, Power BI Desktop enables it automatically"... i understood form the quote we no need to enable R personally

SQL Server R Services lets you execute R scripts in-database. You can use it to prepare and clean data, do feature engineering, and train, evaluate, and deploy machine learning models within a database. The feature runs your scripts where the data resides and eliminates transfer of the data across the network to another server. Base distributions of R are included in R Services. You can use open-source packages and frameworks in addition to the Microsoft packages RevoScaleR, MicrosoftML, [olapR]../r/ref-r-olapr.md), and sqlrutils for R. R Services uses an extensibility framework to run R scripts in SQL Server.
