The instances of the process model that will be affected by modifying the automatic process clean-up settings are future and past instances of the process model. The automatic process clean-up settings allow you to specify how long completed or canceled processes should be kept before being archived or deleted. These settings apply to all instances of the process model, regardless of when they were started or completed. However, these settings do not affect any subprocesses that are part of the process model. Subprocesses have their own archival settings that can be configured separately. References: Automatic Process Clean-up Settings, Archiving Processes

The most likely root cause of the error is that the view contains a large number of rows, requiring more time to fetch the data. This can result in a timeout or an out-of-memory error. To avoid this, you can use pagination or filters to limit the number of rows returned by the view. You can also optimize the view performance by using indexes, avoiding unnecessary joins, and reducing the number of columns. References: [Views], [View Performance]

When building a process model that transforms a large data set, two things that should be ensured to include in the process model are an XOR gateway before the transformation node, to check for empty/null values, and a transformation applied with an expression rule that takes the data set as an input, and loops through the dataset using a looping function, such as foreach. These things can help to improve the performance and reliability of the process model. The XOR gateway can prevent unnecessary processing of empty or null data sets, which can save time and resources. The expression rule can perform the transformation in one transaction, instead of using multiple nodes or subprocesses, which can reduce the memory footprint and the database load of the process model. Therefore, the correct answers are B and D.
