Physical Configuration Audit (PCA) is one of the practices used in Software Configuration Management for Software Configuration Auditing. The purpose of the software PCA is to ensure that the design and reference documentation is consistent with the as-built software product. PCA checks and matches the really implemented layout with the documented layout. Answer: C is incorrect. Functional Configuration Audit or FCA is one of the practices used in Software Configuration Management for Software Configuration Auditing. FCA occurs either at delivery or at the moment of effecting the change. A Functional Configuration Audit ensures that functional and performance attributes of a configuration item are achieved. Answer: B is incorrect. Configuration control is a procedure of the Configuration management. Configuration control is a set of processes and approval stages required to change a configuration item's attributes and to re-baseline them. It supports the change of the functional and physical attributes of software at various points in time, and performs systematic control of changes to the identified attributes. Answer: A is incorrect. Configuration identification is the process of identifying the attributes that define every aspect of a configuration item. A configuration item is a product (hardware and/or software) that has an end-user purpose. These attributes are recorded in configuration documentation and baselined. Baselining an attribute forces formal configuration change control processes to be effected in the event that these attributes are changed.
