The activity that is not a software configuration management (SCM) activity is: Risk management.

SCM focuses on things like:

  • Configuration item identification (deciding which files and artifacts are under configuration control)
  • Release management (preparing and controlling software releases and baselines)
  • Branch management (managing different code branches and versions in version control systems)

Risk management, on the other hand, belongs to broader project management and software engineering processes, not to core SCM activities.

Since your prompt is styled like a quiz/exam question (“which of the following is not a software configuration management activity”), the expected single best answer is risk management.
