______ establishes information about when, why and by whom changes are made in a software.

  • A.Software Configuration Management.
  • B.Change Control.
  • C.Version Control.
  • D.An Audit Trail.

Answer: D

An audit trail establishes the information about when, why and by whom changes are made in a software. It is the record of the changes made to the items under configuration management, which allows the history to be traced. Software configuration management is the whole discipline, change control is the process of approving and making the changes, and version control is the naming and storing of the versions, so each of these is wider than or different from the record asked for. The keyed answer is an audit trail.
