Configuration Management Questions and Answers

Q: Select the components from the following which contributes in the building of software configuration management (SCM) :(i) Software configuration identification (SCI)(ii) Change control(iii) Configuration status accounting(iv) Configuration audit

All four contribute, so the answer is (i), (ii), (iii) and (iv).Software configuration management rests on identifying the configuration items, the work products to be controlled (i); controlling changes to them through a formal change-control process (ii); recording and reporting the status of each item and change, configuration status accounting (iii); and auditing that the configuration actually matches its documentation and that approved changes were made correctly (iv). These are the classic SCM functions.Each of the other options leaves out at least one of them.

Q: The concurrent version system (CVS) is widely used for version control, where it is originally designed for source code, but useful for any text-based file, then CVS system must perform :(i) Establishing a simple repository.(ii) Maintains all version of a file in a single named file by storing only the difference between progressive version of the original file.(iii) Protect against simultaneous changes to a file by establishing different directories for each developer thus insulating one from another.(iv) The CVS merges changes when each developer completes the work.

CVS performs all four, so the answer is (i), (ii), (iii) and (iv).Pressman's description of the Concurrent Versions System lists exactly these: it establishes a simple repository; it keeps all versions of a file in a single named file by storing only the differences between successive versions; it protects against simultaneous changes by giving each developer a separate working directory; and it merges the changes when each developer finishes.Each three-item option leaves out one of these functions.

The concurrent version system (CVS) is widely used for version control, where it is originally designed for source code, but useful for any text-based file, then CVS system must perform :

(i) Establishing a simple repository.
(ii) Maintains all version of a file in a single named file by storing only the difference between progressive version of the original file.
(iii) Protect against simultaneous changes to a file by establishing different directories for each developer thus insulating one from another.
(iv) The CVS merges changes when each developer completes the work.

During the change control process, which of the following activities are required to be initiated ?

(i) While software configuration identification (SCI) is under development it can change freely since it is not under SCM.
(ii) While under review, the software configuration identification (SCI) is considered to be "Frozen".
(iii) Once SCI is reviewed and approved, it is entered into a library; the SCI is now formally under SCM.
(iv) Check in-check out process : once the change has been approved, the SCI has to be checked out from the library for change; once the change has been implemented, the SCI must be checked in to the library.

A.(i), (ii), (iii) and (iv)
B.(ii), (iii) and (iv)
C.(i), (ii) and (iii)
D.(i) and (iv)

Answer: A

All four statements belong to the change control process, so the answer is (i), (ii), (iii) and (iv).

In software configuration management, a configuration item can change freely while it is being developed, since it is not yet under SCM (i). While it undergoes formal technical review it is treated as frozen (ii). Once reviewed and approved it becomes a baseline and is entered into the project library, after which it is formally under SCM (iii). From then on, changes go through check-out and check-in: an approved change checks the item out of the library and checks the modified version back in, which provides access and synchronisation control (iv).

Each option that leaves a statement out omits a genuine stage of the process.
