Question 2: Which UiPath activity should you use to sort a DataTable by a specific column?

Reorder Columns
Sort Data Table
Filter Data Table
LINQ OrderBy expression with Assign (Correct answer)

Correct answer: LINQ OrderBy expression with Assign

UiPath lacks a native Sort Data Table activity, so sorting is done via LINQ: dt.AsEnumerable().OrderBy(Function(r) r('ColumnName')).CopyToDataTable().

Question 3: Which UiPath activity filters rows in a DataTable based on a condition?

Filter Data Table (Correct answer)
Select Rows
Remove Data Row
Query Table

Correct answer: Filter Data Table

The 'Filter Data Table' activity applies column-based filter conditions and outputs a new DataTable containing only the matching rows.

Question 4: What is the purpose of the 'Arguments' panel in UiPath Studio?

To pass data between workflows (Correct answer)
To list installed packages
To configure Orchestrator connections
To define global constants

Correct answer: To pass data between workflows
