   A data engineer needs to process a variable number of input files that arrive throughout the day. The list of files is stored in a Delta table. The engineer wants the Lakeflow Jobs pipeline to process each file by running a notebook that takes a file path as a parameter. Which approach should they use?

   • ACreate a separate task for each possible file that might arrive.
   • BUse a loop that reads the Delta table and runs the notebook for each file path.
   • CUse a retry policy on a single task to process all files.
   • DUse conditional branching to process each file based on a condition.

   A Lakeflow Jobs task runs a Python script that exits with code 0 on success, code 1 on a data validation error, and code 2 on a transient timeout. The engineer wants the task to retry only on the timeout (exit code 2). Which retry condition should they configure?

   • AMatch any exit code.
   • BMatch exit code 0.
   • CMatch exit code 1.
   • DMatch exit code 2.
