Question: Carlos has a Level 0 DFD diagram where one of the external entities is the “Internal Revenue Service” and he has a data store called “Tax Rate Table”. He has drawn a data flow arrow from the Internal Revenue Service to the data store as the data has been loaded into the Tax Rate Table prior to the processing. What would be true?

Answer Options:

This is incorrect, ‘data at rest stays at rest until moved by a process’ so he needs a process (like ‘load Tax Rate Table’) first in this system
This is almost correct. The correct diagram would be a dashed line indicating that the loading of the data was implied prior to the start of this process
This is incorrect – he doesn’t need a data flow as the data was loaded into the Tax Rate Table someplace else (within the payroll system someplace, but not in this process)
This is incorrect. What should happen is an ‘external process’ should be called at the start of the process – like ‘Call IRS for data load’
This is correct

Answer: This is incorrect, ‘data at rest stays at rest until moved by a process’ so he needs a process (like ‘load Tax Rate Table’) first in this system
