What is true when working with loops within a flow?

When working with loops within a flow, creating separate collection variables for use in a loop rather than reusing a variable is a recommended best practice. This approach helps avoid unintended data manipulation or loss of data integrity that can occur if the same variable is modified multiple times during the loop's execution. By using distinct collection variables, you can maintain clarity on which data is being processed and ensure that the original set of data remains intact for any subsequent operations.

This practice is especially vital in scenarios where the original collection requires preservation for later use, or when the data being manipulated needs to be clearly separated for different processing paths within the flow. This method maximizes the effectiveness of the flow logic and minimizes the risk of errors that could occur due to variable re-use within the loop.

The other choices present limitations or misconceptions about flows in Salesforce. These include inaccuracies with the limits on record creation within loops and misunderstandings about governor limits or how collection variables are utilized.
