Which Practice Area contains practices related to limiting access to a particular server that is the repository for controlled baseline product files?

The correct choice is associated with Configuration Management (CM), which focuses on the identification, organization, and control of the configuration of a system throughout its life cycle. One essential aspect of Configuration Management is the establishment and maintenance of controlled baselines for products and their associated files. This involves standard practices ensuring that access to these controlled files is limited to authorized individuals only.

During Configuration Management, practices like establishing and enforcing access controls are critical to ensure the integrity and protection of configuration items. By limiting access to a server containing these baseline files, organizations can prevent unauthorized modifications and maintain the security and consistency of their products.

On the other hand, the other practice areas focus on different aspects of process improvement. Causal Analysis and Resolution (CAR) is concerned with identifying and analyzing the causes of defects to eliminate them, Decision Analysis and Resolution (DAR) involves the process of making informed decisions based on analyzing alternatives, and Monitor and Control (MC) pertains to overseeing processes or performance to ensure they adhere to established requirements. While these practices play vital roles in effective process management, they do not specifically address the access control measures connected to the repository of controlled baseline product files as Configuration Management does.
