What are the two things to consider when deciding if you want to use variables from a BEx Query out of an SAP BW system in your scripts?

There are two correct answers.

Filters require an extra validation round trip to the backend.

Variable values need to be validated, so an extra backend request is required.

Changing a single variable can trigger multiple widgets to be rendered again with each change.

When using multiple variables, the setVariableValue() API must be written one line after the other.

When troubleshooting performance issues, when is script optimization typically required?

Choose the correct answer.

When there are frontend performance issues.

When there are network performance issues.

When there are backend performance issues.

Which of the following statements about the Main thread are not true?

Choose the correct answer.

The Main thread handles the whole story processing.

The Main thread can communicate with all of the data sources.

The Main thread processes the story scripts.

The Main thread responds to requests from the SandboxWorker thread for information that is handled outside of the script.

What are the two core threads that are used when processing a script in an SAP Analytics Cloud story?

There are two correct answers.

Which tool is commonly used to visualize the communication between the Main thread and the SandboxWorker thread when a script is processed in an SAP Analytics Cloud story?

Choose the correct answer.

Browser developer tools, such as Chrome DevTools

SAP Analytics Cloud Performance Insights tool

Script Performance tool

Script Processing Communication tool

Which of the following statements about scripting performance are true?

There are two correct answers.

Data connections do not impact on script processing times.

Performance can vary depending on how the story is set up and how the scripts are written.

Script processing is related to frontend time, so it may be slower, or even faster, depending on the user’s machine.

The getResultSet API in a script is faster and should always be used instead of the getMembers API to read dimension members.

Whatever you code in the onResultsetChanged event script, what do you need to make sure you avoid doing?

Choose the correct answer.

Avoid adding additional results sets to the script.

Avoid changing the same result set.

Avoid adding a getResultSet API to the script.

Which of the following is not a script optimization recommendation?

Choose the correct answer.

Use the getResultSet optional Selections argument that can be used to restrict the return array.

Use a local variable to store the result set instead of multiple getResultSet methods to reduce communication between the Main thread and SandboxWorker thread.

Use a text box to store intermediate states while the script is being processed.

From the statements below, select the ones that are true.

There are two correct answers.

Using the copyDimensionFilter API specifies another data source from where the filter is to be copied reducing the number of backend requests.

Using the setDimensionFilter API with only a member ID causes an additional roundtrip to the backend to retrieve the member description.

Using multiple setDimensionFilter API calls providing the value for the same dimension member as string, they are automatically batched into a single backend request.
