Regex Pattern

Answer

Variable Mapping

Question 3

You are writing a pattern that requires data from a REST API endpoint that returns a nested JSON array. Which step type is most appropriate to extract a specific attribute from an object located at the third index of the nested array?

Answer

It is kept as a temporary CI.

Answer

It is saved in the discovery log.

Question 5

You have a PowerShell script step in your pattern that returns multiple key-value pairs separated by commas. What is the most efficient way to convert this output into a table format for further processing in the pattern?

Answer

Use the Table Transformation step
