48.In Software Configuration Management (SCM), which of the following is a use-case supported by standard version control systems?
(a) Managing several versions or releases of a software
(b)Filing bug reports and tacking their progress
(c)Allowing team members to work in parallel
(d) Identifying when and where a regression occurred
Roger Pressman, in his book, Software Engineering: A Practitioner's Approach, says that software configuration management (SCM) is a "set of activities designed to control change by identifying the work products that are likely to change, establishing relationships among them, defining mechanisms for managing different versions of these work products, controlling the changes imposed, and auditing and reporting on the changes made." In other words, SCM is a methodology to control and manage a software development project. While Version Control System is a subset of SCM and SCM's definition does not contain anything related to team work, hence only (c) Allowing team members to work in parallel; is not the use-case.
